APPROVED BY:
The Carrolls Woods Master Plan Committee has been meeting since early
spring. Their goal was to produce a plan that can be used to guide the
development of the areas of Carrolls Woods and Schwarz Park in conjunction
with a positive relationship with adjoining properties.
In'~addition to the many meetings that the Carrolls Woods Committee held to'
discuss this project there were also two community input meetings held. At
those two meetings citizens were encouraged to voice their concerns and to
share thoughts on this project.
The copy of the concept plan that you received prior to this',council
meeting was developed with the direction of the consulting firm of Brauer &
Associates. Jeff Schoenbauer was the principal representing that firm in
their consulting role.
At the Parks & Recreation Committee meeting of September 16, 1991 this
draft of the Carrolls Woods Master Plan was presented to the committee
members. Following the presentation by Mr. Schoenbauer the Committee did
approve the concept plan and moved to recommend to the City Council that
they also approve the plan.
RECOMMENDED ACTION:
To approve and adopt the Carrolls Master Plan as presented by Brauer
& Associates as apart of the planning process of the Rosemount Parks
Department.

Master Plan for Carrolls Woods Nature Area
Planning Overview
In early 1991 the City of Rosemount undertook this master
planning study for Carrolls Woods Nature Area to define
its long-term purpose and objectives for development.
To accomplish this task, the City.
• appointed an ad hoc advisory committee of local
citizens to oversee the development of a master plan
for the park.
• hired the firm of Brauer & Associates, Ltd. to facilitate
discussion and develop a park master plan document.
The master plan document consists of the following major
components:
• Development Program: defines the park's general
purpose and identifies the major issues affecting its
future development.
• Alternative Concepts: illustrate a number of schematic
designs and physical relationships in response to the
development program.
• Site Inventory. identifies the site's existing physical
characteristics such as soils, slopes, drainage patterns,
etc.
• Site Analysis: makes judgements about the site and
identifies the site's opportunities and constraints for
development.
• Site Master Plan: is an outgrowth of the accepted
concept plan and represents the design solution that
best responds to the development program and site
inventory/analysis information.
• Vegetation Management Program: identifies the key
management objectives to assure long term ecological
diversity and integrity.
• WMdlife Habitat Program: identifies the key
management objectives to assure that the needs of
wildlife are met.
• Cost Estimate and General Phasing Program: projects
the anticipated costs to develop the park and establishes
a general phasing program.
• Education and Interpretive Program: identifies key
objectives of education and interpretive programs.
• Advisory Committee: defines the critical role the
advisory committee will play in overseeing the
development of the park.
The findings related to each of these components are
summarized in the forthcoming text.
Development Program
The Advisory Committee defined during focus meetings
the history and general purpose of the park and identified
the major issues affecting its future development. These
items make up the development program.
The development program is important because it provides
the direction and establishes the basis for the entire master
planning process.
LAWCON Grant
Carrolls Woods Park was acquired by the City of
Rosemount in 1975 through the State of Minnesota's
Outdoor Recreation Grant Program (LAWCON).
According to the original grant application, the intent of
Carrolls Woods Nature Area 1 City of Rosemount
the project was to "protect (from development) a natural,
wooded area within a growing part of the metropolitan
area" and to "provide some outdoor recreational and
outdoor educational opportunities for the citizens of
Rosemount."
In subsequent years the City applied for a number of
revisions and amendments to the original grant.
LAWCON, in most cases, granted these requests.
Since the original grant was obtained in 1975, the City has
created some trails and removed many dead American
Elms from the property. There has been no other
substantial development.
Wayne Sames, Director of the Outdoor Recreation Grant
Program (Community Development Division of the
Minnesota Department of Trade and Economic
Development) represented the State in interpreting the
provisions of the various grant application. Under his
interpretation, the current level of development was
considered to be within the guidelines and general
parameters established as part of the original grant
application and subsequent amendments.
With respect to future development, Mr. Sames indicated
that, under the State's interpretation, the park should: a)
continue to focus on the preservation of the resource and
b) provide passive recreational opportunities, such as
nature observation, educational programs, walking trails,
benches, etc. for the citizens to enjoy.
General Purpose(s) Of The Park
Given their understanding of the park's history and what it
means to the community, the Advisory Committee was
asked to identify what they considered to be the general
purpose(s) of the park:
Conservation and Preservation: to protect the site and
natural environment from encroaching development.
Passive Recreation: to provide opportunities for passive
recreational activities such as:
• walking/hiking (accessible for the handicapped)
• nature/wildlife study
• family and individual "quiet space"
• informal cross-country skiing/snow-shoeing (groomed
for one track of skiing only)
Interpretation and Education: to provide opportunities for
education and interpretation without jeopardizing the
park's natural character. The City and School District
should develop programs for a variety of potential users
groups, including:
• school children of all age groups.
• individuals and families.
• seniors and special populations.
The park should also allow for "passive" educational
opportunities so that an individual can gain knowledge in
an informal manner. This passive education would include
such things as interpretive signs, printed site maps as well
as informational brochures, etc.
General Issues Related To The
Parks's Future Development
Along with identifying the purpose(s) of the park, the
Advisory Committee also identified a number of issues to
address during the planning process. These included:
• a general inventory/identification of existing plant
communities and vegetation.
• a need for a vegetation management program.
• a need to provide wildlife habitat
• a need for an interpretation program to identify and
describe the various plant communities and wildlife.
• a need to encourage the local school district and local
civic groups to participate in the development of a
comprehensive educational program to educate people
(of all ages) about plant communities and wildlife.
• the need to maintain some form of site access and
control. Potential uses of the park which could damage
it included: general overuse, free -roaming domestic
animals attacking wildlife, motorized vehicles entering
the park, and other "nuisance" problems, such as kids
starting campfires, smoking, drinking, littering, etc.
Uncontrolled access also allows a convenient
"thoroughfare" from the west side of the park to the
high school area.
• the need to define more clearly the purpose of the
internal trads. The Committee expressed concerns
about the need to reduce the width of the trails, the
desire for woodchip trails, and limiting the grooming of
cross-country skiing trails.
• the need for additional parkin The Committee
considered the parking lots for Schwarz Pond Park and
Rosemount High School to be too far away and often
unavailable to potential users of the park.
Carrolls Woods Nature Area 2 City of Rosemount
• the need for additional site amenities such as benches,
signs, observation blinds, bridges, etc.
• the need to identify and capitalize on the opportunities
inherent in park's proximity to Schwarz Pond Park and
Rosemount High School.
• the need for neighborhood recreational facilities to
service the recreational needs of existing and future
neighborhoods to the west and north of the park. Note:
this was identified within the overall park system plan
for the City.
• the possibility of including a prairie preserve area within
the park.
• the need to address safety issues (personal and
physical).
Addressing these needs provides the direction and basis for
the entire master planning process.
Alternative Concepts
Three alternative concepts explored different boundaries
for the park and illustrated different management
techniques and relationships between physical uses of the
site. These concepts respond to the issues listed above in
the Development Program.
Figures I, 2, & 3 illustrate three alternative concepts for
the park.
After considerable debate, the Advisory Committee
selected Concept #3 (Figure 3) because it:
• responded to the criteria as set forth in the
development program.
• provided a visionary approach to the park's future
development.
• allowed for more diversity in plant communities and
wildlife species than the other concepts.
Based on these findings, Concept #3, along with the
development program, was used to define the study area
and provide the basis for the continuation of the master
planning process.
Site Inventory
Site inventory identifies the existing characteristics of the
proposed park area (including geology, topography,
drainage, soils, and vegetation).
Based on Concept Plan #3, the study area was broken
down into four adjacent parcels of land, of which
Rosemount currently owns two. The other two parcels
would have to be acquired through parkland dedication,
direct purchase, and/or State grant programs.
Figw 8 - Site .Analysis identifies four parcels within the
study area:
• Parcel A. includes Carrolls Woods as defined by its
current (1991) boundary (45 acres). Acquired by the
City through a LAWCON grant in 1976 for passive use,
nature preservation and environmental education.
• Parcel B: includes the part of Schwarz Pond Park
which lies west of the north -south asphalt trail (e.g.,
west of the existing ballfield). This would include the
pond itself (31 acres). The parcel is already owned by
the City.
• Parcel Q is an area which lies between Carrolls Woods
and an existing gasline easement north of the park. This
parcel is currently used for pasture land and is not
owned by the City (15 acres).
• Parcel D: is an area west of Schwarz Pond, north of
Parcel C, east of a dominant ridge line, and south of a
future collector street. This parcel is also currently used
for pasture land and is not owned by the City (7 acres).
Geology, Topography, and Drainage
Thousands of years ago the climate of Minnesota warmed
and the glacial ice which covered Rosemount began to
melt. As the glaciers receded northwards, they deposited
huge amounts of debris which had been carried in the ice.
The deposits of sand and gravel and boulders, often over
one hundred feet thick, are known as terminal moraine.
The topography of the terminal moraine is rolling with
steep hills, ridges, and landlocked depressions. Some level
areas do exist at the base of slopes, in saddles and
depressions, and on hilltops.
The slopes of Carrolls Woods are mostly hot, south-
southwest facing slopes. The Schwarz Pond parcel is a hot
west -facing hillside. Parcel D has mostly north -facing
slopes and the most moderate topography. Parcel C is a
Carrolls Woods Nature Area 3 City of Rosemount
series of ridges running north to south with steepest slopes
facing east and west.
Glaciers determined the landscape of Carrolls Woods and
set up the drainage patterns which still exist today. Figure
4 - Drainage Pattenrs illustrates the site's current drainage
patterns. These patterns are critical to the formation of
soils and the subsequent development of plant
communities. In Figure 4 - Drainage Patterns, the thick
dashed lines mark the high points of the property and the
boundaries of the watersheds. Water flows in opposite
directions on either side of these lines. It is interesting to
note the north -south pattern of ridges within the study area
which mark the direction of receding glaciers. Because of
the steep slopes of these ridges, the watersheds would tend
to drain rapidly after a heavy rain. Since the watersheds
are small, their lowpoints would not collect much runoff.
Even so, one would expect to find wetlands in the several
landlocked depressions on the property unless the soils are
porous.
Soils
After the glaciers melted, weathering forces began to act
upon the rock and debris left behind and started to form
soils. Soils and slopes are intrinsically related. Slopes
affect the degree of wind and water erosion, the rate at
which moisture is absorbed and retained, and finally in the
amount of sunlight reaching the ground. These factors in
turn affect the growth of vegetation and the subsequent
development of soil strata called a profile.
Any management program should begin with an
examination of the area's soil profiles. Soils offer an
explanation for existing plant communities and affect the
success of any planting restoration efforts.
Figure 5 - Slopes and Soils shows that the study area is
generally a dry site. No clay soils are present. Most of the
soils are sandy or silt loams with moderate to steep slopes.
This means water either runs off rapidly or percolates
through rapidly. The subsoils are usually composed of
several feet of sand and/or gravel. Depressions on the site
are silty loams and poorly drained; these soil types make
up a very small percentage of the total acres of the study
area.
Figure 6 - Soil Quvncterirtics explains the possible uses of
each soil type found within the study area. The Dakota
County Soil Survey states that the hillsides of the study
area are generally most suited to woodland or prairie/
pasture/hay. Tilling is often difficult. The Soil
Conservation Service recommends using drought resistant
species on the most of the hillside soils.
Vegetation
150 years or so ago the Rosemount area was
predominantly oak savannah and prairie. Prairies are
communities dominated by grasses and forbes. Oak
savannahs consist of isolated oaks or small stands of oaks
surrounded by a sea of grasses and wildflowers. Both plant
communities are dependent on fire for continued existence.
The savannahs, with their open vistas and groves of
beautifully -formed craggy oaks, were particularly attractive
to European settlers who were reminded of the parklands
of their home countries. As the settlers turned the
savannahs into home sites and farms, they also suppressed
the fires which are so critical to the continued existence of
the prairie and oak savannah communities. In the absence
of fire, woodland species invaded uncultivated savannahs
and prairies. In the full sunlight between the established
Bur Oaks of the savannahs, Black Cherry, White Oak and
Red Oak sprouted and grew. Sun -loving shrubs such as
Hazelnut, Sumac, Gooseberry and Raspberry also invaded.
When wildfire was suppressed, American Elm, Boxelder,
Hackberry, Green Ash began to take hold. Under their
canopy, the more shade -tolerant shrub species such as
Elderberry, Dogwoods and perhaps Arrowwood and
Nannyberry Viburnums grew. Within 50 years of the
arrival of settlers, the savannahs and prairies of Rosemount
had changed dramatically.
In addition to suppressing fire, the European settlers also
brought with them plant diseases and non-native shrubs
and trees which sometimes out -competed native species.
25 years ago, American Elm probably dominated the tree
canopy of Carrolls Woods. Since then almost all the
American Elm has died of Dutch Elm disease and has left
the central portion of the 45 acre parcel with a very sparse
canopy of trees. Common Buckthorn (Rhamnus
cathartica), a particularly aggressive non-native shrub, has
invaded the property and has virtually taken over the
understory. Tartarian Honeysuckle and woody vines have
also been aggressive invaders. Fortunately in the last
decade the Tartarian Honeysuckle has died out because of
aphid attacks and concerned citizens of Rosemount cut and
reduced considerably the vines strangling many canopy
trees.
Today the canopy of trees in Carrolls Woods is composed
of the following species:
Boxelder (Acer negundo)
Green Ash (Fraxinus pennsylvanica)
Black Cherry (Prunus serotina)
Hackberry (Celtic occidentalis)
Red Oak (Quercus rubra)
Northern Pin Oak (Quercus ellipsoidalis)
Bur Oak (Quercus macrocarpa)
Carrolls Woods Nature Area 4 City of Rosemount
White Oak (Quercus alba)
Silver Maple (Acer saccharinum)
Cottonwood (Populus deltoides)
Aspen (Populus asp.)
Boxelder and Green Ash are the most common trees of
the uplands. Black Cherry and oaks are also quite
prevalent with some beautiful stands of mature individuals
scattered throughout the site. Several Silver Maple
dominate the moist lowlands of the site. One enormous
Cottonwood grows along the trail which runs across the
southern edge of the property. Small mature stands of
aspen are scattered throughout the uplands. Aspen are
short-lived in a forest because they are intolerant of shade.
They may seed in or root sucker into openings, but as the
canopy closes in, they will begin to die out.
Ecologists and foresters examine the understory of a forest
to determine the future of its canopy. The understory of
Carrolls Woods and the forest west of Schwarz Pond has
a rather depressing story to tell. Barring human
intervention or natural catastrophe (fire), Carrolls Woods
will succeed to an almost pure stand of impenetrable
Buckthorn with some Boxelder as the existing canopy trees
die out. There are almost no seedlings of oak or cherry
present in the 45 acres except in small openings with full
sun and no Buckthorn.' Occasional saplings of Green Ash
and Hackberry are present but even they are rare. Shrub
species other than Buckthorn are also uncommon.
Occasional Elderberry and Prickly Ash are scattered
throughout the site.
The ground layer of Parcel A (Carrolls Woods) shows
quite a diversity. Although not closely inventoried, Jack -
in -the -Pulpit, Trillium, ferns and mosses are present in
various areas of the site. These species indicate moist or
mesic microclimate conditions and need shade to survive.
Nettles, gooseberry, raspberry and seedlings of the ever-
present Buckthorn are common along paths and in
openings where there is full sunlight.
Parcel B (part of Schwarz Pond Park ) consists of a hot
west -facing slope which leads down to the pond. The slope
is covered by a well-established canopy of Northern Pin
Oak, Red Oak, White Oak and Black Cherry with a dense
understory of Buckthorn. The eastern and northern shores
of the pond are primarily open with young successional
woodlands of pioneering species (aspen, Boxelder, and
willow) and stands of sumac.
Parcel C is a open, rolling site with one very small remnant
of prairie. The topography is spectacular and interesting.
It is currently used as sheep pasture.
Parcel D is a open, rolling site with some fairly level
topography. It too is used for sheep pasture.
General Perceptions of Vegetation
It is clear that Rosemount citizens are very fond and
protective of Carrolls Woods and the Schwarz Pond
property. Most people enjoy strolling under a lush, cool
canopy of trees in the summer. They appreciate the beauty
of the woods as they are now and are more interested in
sensory experiences rather than how "pure" the ecological
communities are.
Ecologists, on the other hand, see Carrolls Woods through
different eyes: as a forest of mixed hardwoods considerably
degraded by Buckthorn and with a limited future.
The short-term management objectives for the two views
of the woods are opposite; the first demands little
disturbance of existing conditions, the second demands
heavy intervention and manipulation to maintain ecological
diversity.
Left on its current course, the canopy of mixed hardwoods
will continue to die out and be replaced by Buckthorn
which effectively shades out any tree seedling or sapling.
In the not -to -distant future, Carrolls Woods will evolve into
a dramatically different place: a sea of Buckthorn. The
trails will become corridors through a dense mass of 20-
25 foot Buckthorn with no cool shade and no sensory
diversity. At this point in time the two opposite
approaches for forest management will become similar,
demanding intense intervention to recreate the canopy.
The perceptions of the public, rather than the ecologists,
are critical to the acceptance of the Master Plan for
Carrolls Woods Nature Area. Brauer & Associates Ltd.
recognized this and inventoried the vegetation of the four
parcels in a manner which would address these
perceptions. The wooded areas of the study site were
divided into six forest types (see Figure 7.- Vegetation). Each
type has a different type of canopy and understory and very
different visual and sensory qualities.
Site Analysis
Site analysis uses inventory information to make
judgements about the site. Site analysis identifies potential
opportunities and constraints for development.
Access and Control• Users of Carrolls Woods currently
enter the 45 acre parcel from several points. The asphalt
trail running along the eastern border is the most
sanctioned entry point. Several trails of varying widths
enter the woods off this trail. Another main entry point is
Carrolls Woods Nature Area 5 City of Rosemount
at the bottom of a steep hill in the southeast comer of the
property. There are three points of entry along the west
border. The Advisory Committee felt strongly that the
number of access points into the park be limited.
The Committee also felt that entry points will be needed
on the north, west, and east side of the property.
Internal Tram System: Many trails crisscross Carrolls
Woods. They vary in width, degree of steepness, and
quality of the surface. The Committee did not want to
create new trails unless necessary and felt some trails
should be eliminated or realigned.
Currently, individuals often use the trail along the southern
edge of the woods as a way to get from the areas west of
the park to the areas east of the park, particularly
Rosemount High School. As residential development on
the_ west side of the park continues, use of this trail will
likely increase. The Committee felt that this type of
"thoroughfare" was not in line with the park's natural
character and therefore they did not want any trails
developed through the park for this specific purpose.
Figure & Site Analysis highlights those trails which should
be eliminated because they are redundant, too steep, too
wet, or because they serve undesirable access points.
Site Amenities: There are no benches, signs, or other site
amenities in Carrolls Woods. There are many
opportunities for these built facilities which should be
added once restoration efforts for the plant communities
are underway.
Parking: Visitors coming to Carrolls Woods by car must
use the parking lots for Rosemount High School or
Schwarz Pond Park. These are so far away from the
woods that it takes a good walk just to get to the park.
Also the lots are often full.
Topography and existing development around the
perimeter of the site presents a challenge to the designer
of a parking lot which requires level grades. Parcel D has
the most level grades for parking. The two lots owned by
the City in the southwest comer are inadequate in size to
serve the future parking needs of the park.
Neighborhood Recreational Facilities: Parcel D is an
open, rolling area with some fairly level topography. It will
be immediately adjacent to a proposed collector street. In
the near future the areas north and west of this parcel will
likely be developed for residential housing. These
communities will need neighborhood recreational facilities
within walking and biking distance. Parcel D has the
acreage and enough level topography for these recreational
facilities.
Schwarz Pond. The pond within Schwarz Pond Park is a
significant natural area and has value as wildlife habitat.
It has limited value as a recreational lake. The woodland
east of the pond has many lovely oaks and cherry trees.
This area should be included in the park.
Parcel C. With its dramatic topography and open vistas
and its existing use as a pasture, this area is perfect for
prairie and oak savannah restoration. Near the northern
border of Carrolls Woods is a mature, beautifully -formed
Bur Oak and a nice stand of smaller Bur Oaks. The form
of these trees indicates the area could have once been a
savannah.
Woodland Vegetation: the inventory of vegetation in the
study area indicated six types of forest. Each type will have
a different management approach (defined in the
Vegetation Management Program). Control of Buckthorn
will be critical in all areas.
Fi urr 8 Site Analysis simplifies the areas of forest for the
purpose of management.
• Degraded Woods: sparse canopy; isolated mature trees
@ 150-200+ feet apart. Understory is a impenetrable
wall of Buckthorn.
• Open Canopy: mature trees are much more common
and closer together. The understory is still fairly dense
Buckthorn. .
• Pleasant Woods: mature trees form a good canopy with
some Buckthorn in the understory.
• Lowland forest: these small areas are disturbed
frequently by groundwater or wet soil conditions.
Gigantic Silver Maples and Cottonwoods are common
with an ground layer of nettles.
• Successional: young trees, dense understory with a
variety of species.
Master Plan
The Master Plan is a direct outgrowth of the accepted
Concept Plan and represents the design solution that best
responds to the development program and the site
inventory and analysis.
Figure 9. MasterPlan illustrates the results of the planning
process for Carrolls Woods Nature Area. This graphic:
• clearly defines the park's property boundary (consistent
with Concept Plan #3) to ensure diversity of plant
communities and wildlife habitat.
• locates and sizes all facilities and site amenities.
Carrolls Woods Nature Area 6 City of Rosemount
• establishes appropriate plant communities which are the
basis for wildlife habitat.
The following text describes each physical element of the
Master Plan and explains the reasoning behind the design.
Access Control
It is clear that Rosemount citizens feel the need for an
undeveloped area where they can stroll and appreciate the
beauty of nature. A number of recent studies have
documented this need, which is likely to become more
acute as the community continues to grow. Likewise,
Rosemount schools will continue to need a place for
environmental education and interpretation. It is important
to recognize that the park is different from other
community -type parks: its environment is more fragile and
complex. Human activity and intervention can easily
change the character and overall quality of this natural
area.
To insure the long-term preservation of the park, it will be
critical to protect the park from the pressures associated
with urban development. These pressures raise the issue
of control and access.
Currently Carrolls Woods has an unfenced perimeter.
Although it is not easy for the average citizen to reach the
park (parking is far away), it is easy to enter the woods at
any number of locations. There is no perceived
stewardship of the park. This lack of control works fairly
well with the existing level of use of the park and with the
land uses which currently surround the property, i.e.
farmland to the west and north, the high school to the east,
and homes to the south. Without a doubt, this casual
approach to control is ideal and very appropriate in the
near future while the community begins managing the plant
communities of the park and developmental pressures
around the park remain limited.
However times are changing in Rosemount. Within the
next decade residential development will likely occur to the
north and west of the park. As undeveloped land
disappears from the community, citizens will have a greater
desire to spend time in a nature preserve. The City will
want to make access to the park as a community resource
easier for the average citizen by providing parking and
trails. Undesirable activities within the park will increase
as the population of Rosemount grows. Free -roaming cats
and dogs will disturb wildlife. Small footpaths begin to
increase in width as people make their own shortcuts.
Students will cut through the park to get to the high
school. Unauthorized uses (parties, campfires) and
nuisance and vandalism problems tend to increase in areas
that the public does not perceive as controlled. All these
pressures will degrade the woods as a natural area. At
some point in the future the park will likely have to be
protected by some means other than the goodwill of
Rosemount citizens, namely a fence around the perimeter.
This circumstance is certainly not unique to this park.
Virtually all nature centers with limited acreage in the
Twin Cities metropolitan area fence their property. The
fence becomes not only a physical barrier but a
psychological one as well. It makes a statement to the
community that the area is special and needs protection.
By limiting the number of gates, the City can control the
hours and season of use (if desired) and most undesirable
activities. Gates are also opportune places to present rules
and interpretive information. Fences discourage
unauthorized uses, encroachment, and trespassing on
private property.
Specifically, the fence is intended to:
• clearly define the parks perimeter and make a
statement as to its intended purpose.
• protect the park from developmental encroachment.
• restrict site access to pedestrians and maintenance
vehicles and thereby limit trails.
• control free -roaming domestic animals.
• prevent motorized vehicles and bicycles from entering
the park.
• control "nuisance" problems, such as kids starting
campfires, smoking, drinking, littering, etc.
• prevent the park from becoming a convenient
"thoroughfare" between the developing part of the City
to the west and north of the park and the schools and
major community center.
After considerable discussion and debate, the Advisory
Committee recognized that the need for a fence may
become a reality at some point in the park's future and
that a fence should be included in the Master Plan.
However, the Committee also felt that there is no
compelling reason at this point to have the fence high on
the priority list for development. Instead, the Advisory
Committee should review on a periodic basis the need for
a fence, along with other development considerations. The
Committee should use as criteria the items listed above to
determine whether or not the fence is needed. If the site
begins to degrade from unauthorized uses and these uses
cannot be effectively controlled by other means, the City
will have to strongly consider installing the fence to protect
the site.
Initial reactions to the idea of a fence around the park may
be that it is intimidating, unnecessary, and ugly. However,
this does not have to be the case. If installed properly, a
fence can be relatively unnoticeable. Vegetation will screen
Carrolls Woods Nature Area 7 City of Rosemount
it. Psychologically, the fence becomes a barrier to the
human world that, in the not so distant future, will encircle
the park. Those who are involved in the park's future
development should go out to any one of a number of
fenced nature areas within the metropolitan area and see
for themselves how little a fence affects the park's
atmosphere.
Should a fence become necessary in the future, it should be
six foot in height. Galvanized chaird nk fence of a suitable
commercial grade is the most commonly used material
because it is relatively economical to construct and
reasonably durable.
As the Master Plan illustrates, the fence is intended to
essentially follow the park's property boundary. To limit
its visual impact and make it as unobtrusive as possible,
the fence should be set back from 0 to 15 feet from the
property line and be screened by surrounding vegetation.
This is particularly true in the more heavily wooded areas
of the site, where the fence's alignment will be dictated as
much by the existing vegetation as by the property
boundary. Care should be taken during the fence's
installation to limit disturbance to the existing vegetation.
Installing the fence in the late fall when plant life is largely
dormant and avoiding existing trees will minimize damage
to the park. In open areas, planting vines and shrubbery
will help screen the fence from view.
In areas where the fence will be adjacent to existing
residential properties, the City should make homeowners
aware of the fence's proposed alignment prior to its
installation. Some homeowners may prefer the fence along
the property line rather than set back and screened from
view.
The Master Plan identifies four pedestrian gates to provide
access into the park.
The tum -style type, pedestrian -only gate in the southeast
comer of the site will serve the already -developed
residential "core" of the City as well as the school. This
entrance should be very simple and unobtrusive, with an
asphalt trail providing access from the existing roadway
down to the gate.
The access shown on the northwest comer of the site will
serve future residential areas to the west and northwest of
the site. This gate should also be a tum -style, pedestrian -
only gate. To access the gate from the future residential
street west of the park, the City needs to acquire a 24'
wide easement to allow for grading, screening and building
a pedestrian trail.
The Advisory Committee debated at length the issue of
whether or not to provide a pedestrian access in the
southwest comer of the site. After lengthy discussions and
considerable public input, the Committee felt that a gate
in the southwest is appropriate and necessary to serve both
the current and future residential areas to the west and
southwest of the park. As with the other secondary gates,
this gate should also be a turn -style, pedestrian -only gate.
To access this gate from the residential street west of the
park, the City needs to retain a portion of the park
dedication land directly adjacent to this comer of the park.
Retaining a 24' wide strip (e.g., easement) to allow for
grading, screening and building a pedestrian trail should be
adequate. The remainder of the park dedication land is of
limited future value (for the purpose of this master plan
and providing access to the park) and could be, at the
discretion of the Parks Committee and City Council, sold -
off for development, with the proceeds ideally being used
for future development within the park.
With respect to the access in the southwest comer of the
site, adjacent property owners and the Committee were
very concerned about preventing a "thoroughfare" from
being developed through the park along the southern
property line. In this instance, "thoroughfare" means either
a high volume asphalt -type trail and/or a developed
roadway. It is not the intention of the southwest comer
access to serve this type of development in the future. The
only intention (within the context of this master plan) is to
allow residents to the west and southwest the opportunity
to enter the park itself, and not to serve as a direct link to
other areas of the community.
The main entrance gate on the north side of the site will
serve not only those walking to the site but school buses
and those driving to the site from other areas of the
community. This entrance should be simple and natural in
design and make a statement that the visitor is entering the
nature area and a protected environment. This gate should
be limited to pedestrians. A gathering area outside the gate
should accommodate a group of 25 people (a class of
students). This area will include benches and perhaps a
kiosk. Inside the gate, a kiosk provides visitors with a map
of the area and a brief description of what might be seen.
The displays should include photos, graphics, and written
text to describe and illustrate the park's features. The kiosk
should have a leaflet box to dispense park maps/guides.
The Master Plan also includes a number of gates for
maintenance vehicle access. The primary access is near the
main entrance gate on the north side of the park. This
access should serve most maintenance needs once the park
is fully developed. A second access is shown near the
existing hockey rink on the southeast side of the site. This
access will probably serve as the primary maintenance
access until the park becomes more fully developed. This
gate can also be opened in October for participants in the
Haunted Woods program. Third and fourth accesses are
shown near the pedestrian entrance on the northwest and
the southwest. These are intended to be used on a minimal
basis and only to service areas of the park that cannot be
effectively serviced through other gates.
The Advisory Committee also discussed the twenty foot
easement near the southeast comer of the site. Given its
Canolls Woods Nature Area 8 City of Rosemount
relatively steep grades and the current lack of use as an
access to the park, the Advisory Committee felt no action
was necessary at this time. However, the members of the
Committee did agree that the issue should be reviewed
again prior to installing the fence, should the fence become
a reality in the future.
Internal Trail System
An internal trail system which meanders through the park
is intended to move people through the nature area with a
minimum impact to the environment and yet insure that
they receive a quality outdoor experience. Although the
primary objective of the trails is to link together the various
plant communities, the system should also be developed to
take advantage of the varying topography, views, and vistas.
The trails should provide visitors with a variety of
perspectives and experiences.
Yzgum 10- Typical Tial Cross Seddon for GVTOUs Woods
Nature Area shows the suggested design for internal trails.
In order to keep the experience of the woods as intimate
as possible, the width of the trail should ideally be six feet
with a one foot maintenance strip on each side. Although
this would be ideal, it should be recognized that the trail
widths will have to be somewhat wider in at least the near
future since the City's current maintenance equipment
cannot economically maintain an eight foot wide trail
corridor. Instead, a ten foot wide trail corridor is a more
realistic expectation at this time, with the width potentially
being narrowed over time as new equipment becomes
available.
The surfacing material should be:
• compacted crushed aggregate (suitable for handicap
accessibility) on the primary loop within the wooded
and prairie/savanna areas.
• woodchips on the auxiliary and secondary trails within
the wooded areas.
• mowed grass on the auxiliary and secondary trails
within the prairie/savanna areas.
Because one of the primary development objectives is to
limit disruption to the existing mature vegetation, the
Master Plan uses existing trails within the park as much as
possible. However, some changes will be needed where
existing trails do not serve a future purpose and/or where
their grades are excessive. In some cases, trails will be
eliminated because they serve undesirable access points.
Since the existing trials vary from four to twelve feet in
width, they will require some reworking, much of which
can begin immediately. Also, even though the trails shown
on the Master Plan may follow existing alignments, they
may need redesigning to make sure that they are safe and
maintainable.
The new trails shown on the master plan supplement the
existing trails. All of the trail alignments, both old and
new, should give the user a quality experience of the park
with many options for routes to walk. The exact location
of each trail must be established in the field during design
development (i.e. the "next step" in the planning process)
to take advantage of the opportunities afforded by the site.
In other words, the trail alignments as illustrated on the
Master Plan should be considered approximate and not
absolute.
As with the existing trails, new trials should be designed to
make sure that they are safe and maintainable.
Carrolls Woods Nature Area should be a community
resource in the winter as well as in the spring, summer and
fall. Snow and ice can be barriers to using the trails. The
Advisory Committee felt that a single groomed track for
cross-country skiing would allow people to experience the
woods in winter and would not detract from the quality of
the environment. A single pass through the woods by a
snowmobile trailing a pair of weighted skis would create a
narrow trail for skiers which would not damage
surrounding vegetation.
Site Amenities
Enhancing the perceptions and experiences of park visitors
through the careful use and placement of site amenities is
important and will greatly affect the overall success of the
park as a public resource. Site amenities are the built
features which increase the comfort/access of the park
users. As with the trial alignments, the exact locations of
the various site amenities must be established in the field
during design development to take advantage of the
opportunities afforded by the site.
All of the site amenities should be natural and simple in
design and as much as possible blend into the environment
that surrounds them.
Interpretive Nodes and Signs: interpretive nodes are
places along the trail with low profile kiosks. These kiosks
have interpretive panels and exhibits which are fun and
easy to read with good graphics and minimal text.
Interpretive nodes are typically located near benches and
other site amenities (i.e. decks, docks, etc.). Located
along the trails, unobtrusive interpretive signs will identify
the various plant communities and wildlife species and
augment the interpretive nodes.
Benches: should be provided to take advantage of different
views and site features, ranging from quiet, intimate spots
to wide open vistas. Again, benches can be installed at
Carrolls Woods Nature Area 9 City of Rosemount
interpretive nodes if appropriate.
A Floating Boardwalk: located in the wet prairie area gives
park users an close -hand experience of the tall grasses and
Forbes of the wet prairie.
Environmental Education Dock: provides an educational
opportunity for school children so that they can study pond
life and take water samples, etc. In addition, the shop
students from the local schools could help construct the
dock as part of their classes.
Pond Overlook Dock provides park users with a pleasant
place to sit and view the pond. Two benches allow seating.
Pond Observation Blind: provides park users with an
opportunity to view waterfowl activities. If properly
designed, the blind hides people whose presence and
movements normally scare the waterfowl away. The blind
is on the edge of the pond and surrounded by vegetation
to help screen it from view. An elevated catwalk from high
ground provides an interesting access to the blind.
Wooden Bridge Across Woodland Pothole: is a simple
structure with a railing that crosses the woodland pothole
at a narrow point.
'Lookout" Tower. gives park users a birds eye view of the
area and is another opportunity for a visitor to observe
nature in relative anonymity. A height of thirty feet should
elevate the tower platform above most of the understory
trees.
Woodland Deck is another simple structure with benches
designed for resting and observing nature.
Cottage House for Interpretive Displays, Storage,
Meetings, Restrooms, Etc.: is a simple building to serve the
listed uses. The building should be sited near the main
entrance gate at the edge of the savannah. It should have
a low profile and use natural materials to blend into the
surroundings. A patio outside the building allows visitors
a place to sit and observe the prairie.
Entrance Drive and Parking
Since the entrance drive is the first contact that visitors
have with the park, it should be located in a manner which
compliments the existing topography. The entrance drive
will tie into a future collector street which is likely to be
developed north of Schwarz Pond Park.
The parking lot at the end of the entrance road should be
sized to prevent overuse of the park but large enough to
allow a bus to turn around. Ideally, the lot should be
paved with asphalt to minimize long-term maintenance and
dust.
Since the entrance drive and lot are outside the nature
area itself, they will technically be part of Schwarz Pond
Park. Users of the picnic areas on the west end of the
park will probably park in the lot. A lot for 35 to 50
spaces plus several bus parking stalls will probably be
sufficient to satisfy the parking needs of the users of both
the nature area and Schwarz Pond Park. However, as
actual design and construction of the lot and entrance road
become reality, the City should closely examine potential
demand for parking and size the lot accordingly.
Neighborhood Recreational Facilities
The city-wide park system study identified the need for
neighborhood recreational facilities for this area of the
community. Parcel D is an open, rolling area with some
fairly level topography and is adjacent to the proposed
collector street. Parcel D is the best site within the study
area for neighborhood recreational facilities.
Since it is the policy of the City to include input from area
residents when determining what recreational features will
be in the park, the facilities shown on the plan are for
reference only and need to be confirmed (or changed)
when development actually occurs.
These recreational facilities should be connected by trails
to the community -wide trail system.
Schwarz Pond Park
The pond within Schwarz Pond Park is a significant natural
area which could add greatly to the diversity of plant and
wildlife habitat within the park. The area east of the pond
can provide excellent waterfowl nesting habitat if current
mowing practices are discontinued and the City restored
the area to prairie. Fencing (should it become necessary)
and wildlife plantings along the asphalt trail would keep
domestic animals from disturbing nesting areas.
The woodlot west of the pond is a beautiful natural area
which justifiably should be included and managed as part
of the park. Its location next to the pond enhances the
wildlife value of both areas.
The pond is a ecological community which' has important
education and interpretive possibilities. The City and
Rosemount School District should monitor the pond's
water quality and protect its integrity as a resource by
establishing water quality guidelines.
The Master Plan shows a number of amenities within
Schwarz Pond Park and outside the nature area. These
amenities include two scenic overlooks and a number of
Carrolls Woods Nature Area 10 City of Rosemount
picnic areas near the parking lot. The overlooks should be
mowed areas or decks with benches overlooking the pond.
The picnic areas should also be simple in design, with a
number of picnic table and grills and perhaps a small -
group picnic shelter.
External Trails
External trails provide access to park entrances and play
an important role in how well the park ultimately serves
the residents of Rosemount. The four entrance gates
should tie into the community -wide trail system which is
defined within the City's Comprehensive Park Plan and
Development Guide.
The existing asphalt trails on the east side of Carrolls
Woods and Schwarz Pond will ultimately be outside the
(fenced) nature area.
The trail link to the southwest entrance can easily tie into
the already established community trail along the 142nd
Street West. Since the trail does run across school
property, the district would have to be involved in
determining its exact location.
The trail links to the northwest, southwest, and main
entrance gates are also very important and should be
developed in conjunction with future roadway and
subdivision development.
The Advisory Committee and City should review access
concerns periodically and in conjunction with planned
development in the area to insure that trail access
opportunities are not lost along the way.
Vegetation Management Program
The Vegetation Management Program identifies the
management approaches and procedures to guarantee the
ecological diversity of the park so that it will be a treasure
and resource for future generations.
In order to maintain long-term ecological diversity and
integrity, the wooded portions of the park must be
managed and improved and the open areas need to be
restored to prairie or savannah.
Vegetation management programs can be geared to create
five different types of sensory experiences of the park and
adjacent parcels. These sensory experiences also represent
different ecological communities.
Dense canopy. 75%-95% overstory coverage with sparse
understory (relatively open). Sensory experience: lush,
shady, cool. Open feeling under a ceiling of trees. Long
views through woods. This type of feeling is most common
in a lowland forest or in a mature Sugar Maple -Basswood
forest. The latter requires moist (not wet), protected and
semi -shaded conditions. Neither Sugar Maple or Basswood
grows naturally on the site; introducing these species would
create an anomaly or artificial condition. It might be
beneficial to attempt to create this woodland community
for an environmental education program.
Moderate canopy. 40%-60% overstory coverage with
moderately dense understory. Cool shade dappled by
sunlight, limited views. Common in a mixed hardwood
forest. This sensory experience is probably most popular
among Rosemount citizens and already exists along most
of the trails and along the northern edge of Carrolls
Woods.
Sparse canopy. less than 15% overstory coverage and dense
understory. Without fire, this community is dominated by
aggressive pioneering plants. The sensory experience in
summer is hot, walled -in, transitional, young, not as
appealing as types listed above. This condition is frequent
in the center portion of the site with dense Buckthorn.
Savannah: mostly open with occasional spreading individual
trees or small stands of stunted trees. Intense sunlight with
pockets of shade. Bright, hot, open, windy in summer. In
winter, savannahs feel exposed and cold; snow melts away
quickly especially on south -facing slopes. Attention focuses
on landform and trees. Oak savannahs are rare plant
communities today.
Prairie: open, hot, often uncomfortable in the summer
unless there is a good breeze. Pleasant in spring and fall.
Windy and unprotected in winter; snow disappears quickly
on south -facing slopes. Attention focuses on landform, the
texture and color of grasses, the washes of color from
wildflowers. Prairies can grow in a variety of situations:
from wet, poorly drained areas to dry, barren hilltops.
Available water and the depth of topsoils determine which
species of grasses and wildflowers will best grow.
Existiung Site Opportunities. The two wooded parcels
within the study area (Parcels A & B) currently provide
opportunities for nature lovers to enjoy two types of
Minnesota forests: the dry upland forests of mixed
hardwoods (oak, cherry, ash, Hackberry) and lowland
forest of boxelder, cottonwood and silver maple. Parcel A
(Carrolls Woods) has one north -facing slope which could
provide the cooler microclimate conditions needed for a
moist upland forest (Sugar Maple -Basswood).
Parcel C is an open, rolling site with one very small
remnant of prairie. The topography of this parcel is
spectacular and interesting and has great potential for
prairie and oak savannah restoration. If possible,
Carrolls Woods Nature Area 11 City of Rosemount
Rosemount should acquire enough land to control the
viewshed (Le. to the tops of ridge lines) and should also
consider scenic easements.
Aesthetics suggest softening the straight line boundaries
between woods and pasture (prairie) that exist along the
northern boundary of Parcel A (Carrous Woods) and along
the eastern border of Parcel B (Schwarz Pond Park ). For
this reason, some of the oak woods along the western edge
of Parcel B be restored to savannah.
Since savannah is more easily restored than recreated,
Rosemount should treasure the savannah type oaks (Le.
100-150 year old Bur Oaks with rounded canopies) which
exist within the study area.
Management Objectives. The management objective of
woodland management within the nature area is to
maiptain diversity within the existing woodland
communities. This will insure that the future generations
will be able to enjoy a forest of trees rather than a
monoculture of Buckthorn.
Woodland management will be a tricky issue for the City.
The Buckthorn infestation is so severe that removing it will
devastate the forest for a few years until other species take
hold. Unfortunately, there is no alternative if Rosemount
citizens want to achieve the long-term goal for the park
with ecological diversity. Phasing and public
awareness/education will be critical to public's
understanding of what is happening within the park and to
their support of management efforts.
The restoration of prairie and oak savannah should not
create the same concerns as the woodland management
program. The proposed sites for these communities are
currently in pasture and restoration efforts will not appear
to change the area so dramatically. Burning may present
some problems, but again publicity and sensible scheduling
will limit public concern.
Vegetation Management Plan
Kigum 11- Vegetation Management divides the park into
several zones. Each zone is described by.
• a letter/number code.
• a phase number.
• an approximate acreage figure.
The first part of the code describes the ecological
community (e.g. WO = Woodland - Mixed Hardwood, P
= Prairie, S = Savannah, etc.). The second part of the
code is an alphabetical letter which describes the method
of restoring or managing the ecological zone. These
methods are described in detail below. The third part of
the code is a number which describes the priority of the
zone for management/restoration. Zone 1 is the highest
priority within a particular ecological community and Zone
9 is the lowest. Ytgure 12 - Vegetation Management Phasing
Progr+wn describes phasing in more detail.
Prairie Areas (Method A or P -A-#)
The City should hire a firm specializing in prairie
restorations such as Prairie Restorations of Zimmerman,
Minnesota or Prairie Nursery of Winona, Minnesota.
These firms offer advice and a range of services including
burning and planting. Make sure the chosen firm uses
prairie seed collected within a 200 mile radius of
Rosemount. Non-native seeds can be aggressive, resulting
m one or two species dominating the site.
Mow fire breaks around the perimeter of the future prairie
areas.
The experts from the prairie restoration firms will
recommend the best technique for restoring the prairie
grasses and forbes appropriate to each particular microlite.
The nursery may recommend burning the entire prairie -
designated area to see what surprises the seed bank in the
soil holds. Prairie seed can lie dormant for years in the
soil. Next, the experts may recommend one or two general
or local applications of Round -Up. This herbicide will kill
all vegetation. The next step is to use a Truax Drill to
plant seeds of prairie grasses. The following year the
restoration firm may mow and plant by hand forbes or
wildflowers (1000/acre).
In the beginning a prairie should be burned every year in
order to eliminate weeds and the woody plant materials
which naturally invade an open site. Burning also creates
spectacular wildflower displays. Once established, a prairie
should be burned every 3-5 years. Although other
techniques, such as mowing, can be used in the restoration
process, burning is typically the most effective (and
natural) and should be used when at all possible and
permitted by the City. Communicating with nearby
residents about the burning process and burning under
ideal conditions will go a long way toward minimizing or
mitigating the negative aspects of this procedure.
Recreated Oak Savannah (Method A or S-A-#)
In these designated savannah areas, mow 10-15 foot fire
breaks around the edges to prevent the fire from jumping
into the adjacent woods.
Carrolls Woods Nature Area 12 City of Rosemount
Hire a prairie restoration firm. Restore prairie. Once the
prairie community is established, tree spade in small Bur
Oaks ( 2" -3" diameter at breast height). Plant the Bur
Oaks in clusters or as isolated species 150-200 feet apart.
The City can reduce costs by transplanting Bur Oaks from
other City property or by donation from private property.
This transplanting can occur over a period of years. All
plant stock should be obtained from a local source to
insure its hardiness.
Examine the transplanted trees after one season. If they
are doing well, leave them be. If they appear sick, cut the
trunks off around 6-12 inches above ground. The Bur
Oaks should sprout from the base. After 2-3 years, select
a main leader and prune off the rest.
The Bur Oaks seedlings will need Tubex Tree Shelters
(@$5.00 apiece installed) to protect them from deer
browsing.
Initially, a savannah should be burned annually. The young
Bur Oaks need protection from the heat of the fire. Mow
a 16 foot diameter circle around each oak to protect it
from damage.
Once sufficient shade is established, plant the forbes and
grasses unique to a savannah community.
Restored Oak Savannahs (Method B or S -B-#)
Oak Savannahs are more easily restored than created from
scratch. A few savannah type trees exist along the
northern edge of the Carrolls Wood. These are Bur Oaks
with well -formed rounded canopies; they look like they
have always grown in the open rather than in cramped
forest conditions. Mature Bur Oak have thick corky bark
which makes them resistant to quick ground fires common
to prairies.
In the designated savannah areas, mow 10-15 foot fire
breaks around the edges to prevent the fire from jumping
into the woods.
The City should also hire a prairie restoration firm to assist
in restoration of prairie grasses and forbes within the
savannah areas.
In the fall cut and remove undergrowth (usually
Buckthorn). Paint the herbicide Garlon on cut surfaces of
stems. The next spring, bum. Because of lack of fuel it
may take a few years to get a complete bum. Savannah -
type grasses and forbes should start to reappear.
After an area is burned, seed in handfuls of grasses and
forbes (seeds and berries) appropriate to an oak savannah.
The prairie restoration firm can provide some of these
species. Others may have to be collected by volunteers
from local areas.
Initially a restored savannah should be burned every years.
Once the understory of desired species is established, the
burning can be done every three to five years and,
eventually once every ten to fifteen years.
Oak Woodland (Method A or WO -A-#)
This restoration method is for degraded woods (see Figure
8: Site Analysis) with a sparse canopy or isolated mature
trees @ 150-200+ feet apart. The understory is a
impenetrable wall of Buckthorn. These woodland areas
will be the most costly and exasperating to restore. This
method of management is geared towards eliminating the
dense understory of Buckthorn and replacing it with more
desirable species. This is a multiyear process because
Buckthorn is a prolific seeder.
Year One: In the fall or winter, cut and remove adult
Buckthorn (any stem over ; inch in diameter if possible).
Treat the cut stems with Garlon. This phase will eliminate
90-95% of the Buckthorn biomass. It is extremely labor
intensive (Rosemount may want to organize volunteer help.
A person licensed to apply herbicides must be in charge of
training and overseeing the volunteer help.)
Year Two: Plant 75 saplings per acre. Plant Red Oak,
White Oak, Black Cherry, and Green Ash. Use the Tubex
5' tree shelters for these saplings. These tubes will serve
3 functions:
• protect the saplings from rodents and deer
• create condensation which will help the saplings survive
the drought -prone soils.
• protect the saplings from herbicide sprays.
After planting, use a foliar spray (such as Krenite .or
Round -up) to kill off all the Buckthorn seedlings. These
sprays will kill any green growing plant that they contact.
Buckthorn remains green and growing in the forest 2-14
days after most native vegetation goes dormant in the
autumn. This time may be the best time to spray in order
to preserve as much non -Buckthorn understory vegetation
as possible. Rosemount will need expert advice from the
herbicide distributor as to timing of application (the
window of opportunity varies from year to year and can be
quite small).
Year Three: Apply a foliar spray again to eliminate any
remaining Buckthorn seedlings. Seed each acre with
Canons Woods Nature Area 13 City of Rosemount
acorns or plant oak/cherry seedlings (2000/acre). The
DNR sells 1000 tree seedlings for $150. Acorns are not
available commercially, collecting them could be a
volunteer effort in early to mid August. One drawback for
acorns is that not every year is a productive year for oaks
to produce them.
Subsequent years: Monitor the restored areas for
buckthorn regeneration. Continue to eliminate either by
cutting and applying Garlon to the cut stems or by using
foliar sprays for pockets of infestation.
Oak Woodland (Method B or WO -B-#)
This management method is for pleasant woods (see Ylgure
8. Site Analysis) with a well-developed canopy of mature
trees and a moderate Buckthorn understory. Management
efforts should be directed at eliminating Buckthorn,
especially the mature individuals and ones in the occasional
openings in the canopy, and supplementing the planting
especially in openings.
Year One: Cut and remove adult Buckthorn (over 4 inch
in diameter). Apply Garlon to cut stems. Replace the
Buckthorn with tree saplings or shade -tolerant shrubs.
Possible species:
Common or Scarlet Elderberry (Sambucus canadensis
or pubens)
American Hazelnut (Corylus americana)
Nannyberry (Viburnum lentago)
Gray Dogwood (Cornus racemosa)
Pagoda Dogwood (Cornus alternifolia)
Round -Leafed Dogwood (Cornus rugosa)
Serviceberry (Amelanchier canadensis)
Gooseberry (Ribes cynosbati)
Raspberry (Rubus strigosus)
Prickly Ash (Zanthoxylum americana)
Green Ash (Fraxinus pennsylvanica)
Red Oak (Quercus rubra)
Northern Pin Oak (Quercus ellipsoidalis)
White Oak (Quercus alba)
Black Cherry (Prunus serotina)
Hackberry (Cells occidentalis)
All plant stock should be obtained from a local source to
insure its hardiness.
If there are any large openings in these zones with solid
stands of Buckthorn, eliminate using Method A.
Year Two: Monitor these zones, cut and apply Garlon to
any remaining Buckthorn. Continue to add shrubs and
saplings if needed. Begin to enrich the herbaceous layer
in shady areas with appropriate wildflowers.
Oak Woodland (Method C)
This restoration method is for north -facing slopes with an
open canopy and a fairly dense understory of Buckthorn.
For areas without canopy trees and heavy Buckthorn, use
Method A. When planting, use the species listed below.
For areas with canopy trees and some Buckthorn, use
Method B.
Species to plant:
Sugar Maple (Acer saccharum)
Basswood (Tilia americana)
Ironwood (Ostrya virginiana)
Black Cherry (Prunus serotina)
Hackberry (Celtic occidentalis)
Red Oak (Quercus rubra)
Butternut (Juglans cinera)
Black Walnut (Juglans nigra)
All plant stock should be obtained from a local source to
insure its hardiness.
As the Buckthorn is eliminated and the canopy begins to
fill in, enrich the forest floor with wildflowers called spring
ephemerals.
Lowland Woods (WL)
These small areas of the site are disturbed frequently by
groundwater or wet soil conditions. This community will
not require much management except to prevent
disturbance of the drainage systems and to eliminate
infestations of Buckthorn.
Successional Woods (WS)
Successional forest: these areas are dominated by
pioneering plants and have few mature trees and a dense
understory of a variety of species. The only management
needed for these areas is to control Buckthorn invasions.
Woodland Pothole
The area in the southwest comer of Carrolls Woods was
once quite productive waterfowl habitat. In the last twenty
years it has silted in and become dry enough for Silver
Maples to grow. To make the area a pothole again, it
must be dredged, regraded, and perhaps sealed to prevent
water from seeping away. If possible the City should
Can -oils Woods Nature Area 14 City of Rosemount
construct a small siltation pond to filter all stormwater
runoff before it enters the pothole. Once open water is
provided, the bird (and animal) life will return.
Schwarz Pond
The fluctuations in water levels for this pond actually
increase its productivity as a food source for waterfowl.
Discontinuing mowing and planting prairie would improve
this area as habitat for birds and animals. Some wildlife
plantings along the fence will help screen it. The City or
school should monitor water quality in future years.
Wildlife Habitat Program
One of the primary objectives for this park is to establish
diverse wildlife habitat which provides food, water, and
shelter for a variety of wildlife species.
Although the pallet of plants included in the Vegetation
Management Program for the park will provide habitat for
several wildlife species, a wildlife management program
will add extra components to improve the diversity of
species using the nature area.
A number of state and regional resources are available to
help develop a wildlife habitat and management program.
The Minnesota Department of Natural Resources (D.N.R.)
have individuals with expertise necessary to:
• evaluate existing habitat and its potential to support
wildlife.
• recommend habitat development programs to improve
the habitat that is already present.
• identify the bearing capacity of the park and ways to
maintain a healthy wildlife population.
The City should contact the D.N.R. Section of Wildlife
prior to future development to insure that no opportunities
are missed along the way.
Based on the DN.R.'s guidelines, fifteen components of
wildlife habitat are necessary to fulfill the major needs of
most species. Eight of these components are plants and
eight are structural or non -living components.
Plant Components:
• grasses/legumes
• butterfly, bees, moth plants
• hummingbird plants
• summer plants
• fall plants
• winter plants
• nut/acorn trees
Structural Components:
• feeders
• water
• dust beds/grit
• salt
• cut banks/cliffs/banks
• brush/rock piles
• snags
• nest boxes
By providing these components, the community will
improve the chances of wildlife flourishing within the
confines of this nature area.
Cost Estimate and General
Phasing Program
Although certainly not an exact science, estimating or
projecting the costs to develop this park is important
because it provides the citizens of the community,
governing bodies, and City staff with a basic understanding
of the economic commitment necessary to put the park's
Master Plan into effect. The estimated costs to develop
the park will affect priorities for adding the various
components and amenities and in deciding which ones are
best accomplished through volunteer efforts versus paid
contracts.
The City and Advisory Committee should use the figures
below only as 'benchmarks" to compare the relative costs
of items and for budgeting purposes. Actual cost to
acquire land and develop the Master Plan will depend a
great deal on:
• the actual land values at the time of acquisition.
the actual construction costs at the time of
development.
• how much of the costs for development can be offset
through alternative funding programs, such as
volunteerism, grants, donations, etc.
The cost estimates below are based on estimated land
values in 1991 dollars (determined by the City) and typical
development costs in 1991 dollars (as determined by
industry cost -to -construct averages, i.e. what it would
typically cost, on average, for a contractor to come in and
do the work).
Carrolls Woods Nature Area 15 City of Rosemount
Park Land Acquisition Costs
The Master Plan includes two parcels of land which the
City does not currently own.
The first parcel (Parcel C) has the highest priority for
acquisition because it plays an critical role in the long term
objectives of the Master Plan. Based on current land prices
in the City of $8,000 to $11,000 per acre, the cost for the
15 acres identified in the master plan would range from
$120,000 to $165,000.
The second parcel (Parcel D) plays an important secondary
role in the long term objectives of the Master Plan. It
provides an area for support facilities (e.g., parking lot)
and neighborhood recreational facilities. Again based on
current land prices in the City of $8,000 to $11,000 per
acre, the cost for the 7 acres identified in the master plan
would range from $56,000 to $77,000.
Although these two parcels play an important sole in the
park's Master Plan, they may not be either available for
purchase or the City may not be 'able to fund their
acquisition. If this becomes the case, the overall integrity
of the Master Plan is not lost. Even without these parcels,
the park will be a priceless natural resource and will make
a significant contribution to the park system within the
community. However, if the vision of this master planning
process is to be realized, every effort should be made to
include these parcels within the park.
Park Development Costs
The cost estimate and general phasing program for
developing the park is illustrated in Figure 13 - Cost
Estimate and General Phasing Program.
The suggested phasing is based on the most reasonable
approach to the park's future development. The vegetative
management programs are the top priorities. The auxiliary
site amenities can be added in the future. The phasing
program is based on the best judgements given current
conditions. Since conditions and opportunities often
change over time, the City and Advisory Committee should
review the phasing program on a periodic basis to change
priorities if necessary.
Interpretive/Education Programs
One of the important program elements for this park is the
an. interpretive and environmental education program to
emphasize the importance of preservation and conservation
of limited natural resources.
The programs should focus on native plant communities,
how they evolve and maintain themselves, and on the
wildlife which depend on them for survival. These
programs should also emphasize the use of native plants
around homes and the benefits they provide, both in an
aesthetic and practical sense (such as wind screening,
shade, attraction to wildlife, etc.).
Environmental education programs for elementary and
secondary schools should be a high priority, considering the
park's proximity to the nearby schools.
The Minnesota Department of Education often assists
communities in developing environmental educational
programs. State personnel, along with local school district
staff, should be contacted and asked to help create these
programs.
Interpretive programs should be created to reach a wide
variety of people and age groups. Interpretive programs
typically focus on providing park visitors with information
about the plant communities and wildlife within the park.
These programs often include:
• interpretive nodes (low profile kiosks with interpretive
panels).
• interpretive signs throughout the park which describes
different features.
• maps and handouts with text describing the park's
ecological systems, wildlife, geology, etc.
Development of interpretive programs should also include
the Minnesota Department of Education, local school
district staff, as well as a naturalist and other
environmental professionals.
Existing Community Programs
This Master Plan does not intend to exclude existing and
successful community programs from taking place within
park boundaries. However these programs should occur.
only if they do not cause significant negative impacts to the
park's natural character. Organized events bring visitors to
the park and create experiences which give people a vested
interest in the future of the park. A pleasant memory of
a place can motivate people to protect it as a resource.
As an example, there is no compelling reason why the
Haunted Woods program should not continue as it has in
Carrolls Woods Nature Area 16 City of Rosemount
the past as long as its organizers take reasonable care to
protect fragile plant life from damage. To accomplish this,
organizers of community programs should work closely
with the Advisory Committee in selecting a route and
location for props. In the future, when the nature area is
fully restored and developed, the Haunted Woods program
may be better suited to another location. The organizers
should work with the Parks and Recreation Committee and
city staff in the next few years to see if another more
suitable site exists. In the interim, the Haunted Woods
program should continue.
Advisory Committee
The.City should establish an advisory committee to oversee
and guide the future development and protection of
Carrolls Woods Nature Area. The Committee should be
made up of individuals with different backgrounds who can
help give direction and motivation to the community in
support of the park's Master Plan. The Advisory
Committee should work directly with the Parks &
Recreation Committee and City staff to guarantee that the
park's best interests are served.
The Parks and Recreation Committee and City Council
should formally accept the Advisory Committee in an
advisory role and as the guiding force behind the park's
future development in order to add strength to Advisory
Committee's position.
The Committee's make-up should include:
• local citizens who are concerned about the park's future
and want to contribute their energies toward insuring
that its mission is carried out.
• members of local conservation organizations with
interest and expertise in native habitat, wildlife
observation and wildflower gardening.
• members of local garden club(s) who have a special
interest in native plants and gardening.
• teachers in the local educational community who have
an interest in environmental education and
interpretation.
• community leaders who can provide political guidance
and potential sources of private funding.
• a City staff member(s) to assist in guiding the project
through administrative and political channels.
The Advisory Committee's involvement in the development
of the park should occur prior to the design development
stage of the project. The Advisory Committee should use
the Master Plan as a guide to any development within the
park. Other key responsibilities for the Committee
include:
• interpreting the master plan document, including
periodic review of the plan itself and the priorities for
phasing.
• implementing the plan, including scheduling of
improvements, securing professional assistance as
necessary, and making recommendations to the Parks
& Recreation Committee, City staff, and City Council.
• initiating education and interpretive programs.
• initiating public awareness programs and public meeting
to keep the citizens of Rosemount aware of the park's
development.
• initiating volunteer programs to assist in the
development of the park and reduce development costs.
• providing on-going guidance and support to volunteer
and educational programs to insure the long-term
success of the park.
• monitoring maintenance practices so that, they stay
within the intent of the Master Plan.
• monitoring existing community programs (such as the
Haunted Woods) and work with program organizers to
guarantee that the best interests of the park are served.
Conclusion
The citizens of Rosemount should commend its City
Council, Park and Recreation Committee, and the Advisory
Committee for their concern in planning for such a
valuable community resource as the Carrolls Woods
Nature Area. The Advisory Committee in particular put
in many hours debating the issues facing this park and
came to some tough and critical decisions about its future.
Carrolls Woods Nature Area is a treasure for future
generations. Rosemount is lucky to have citizens who feel
passionate about its existence and the quality of its
environment. Their energy can go a long way toward
motivating the community and creating the support
necessary to implement the Master Plan.

Mr. Dave Bechtold, Park and Recreation Director
City of Rosemount
City Hall
2875 - 145th St. West
Rosemount, MN 55068
Dear Dave,
Given my involvement in the Carroll's Woods issue over the past
year or so I thought it would be appropriate to comment on the
proposed master plan. As you know, I have had an opportunity to
reveiw the draft master plan and attended some of the committee
meetings and one of the public information meetings.
In general, I think the proposed master plan for Carroll's Woods is
an excellent document that should provide a solid basis for long-
term management and development of the park. I believe that it is
consistent with the purposes of the original grant request and the
requirements of the grant agreement.
On the issue of trails, I believe the plan goes a long way toward
resolving some of the concerns I had. For example, the
recommendation to eliminate some trail segments, particularly on
steeper slopes, is a good one. I feel the committee's original
suggestion to provide an entry point on the northwest corner of the
park was reasonable, given the inevitable residential development
that is bound to occur in that area. The possible compromise,
suggested by one member of the committee, to enter the park
somewhere between the northwest and southwest corner also seemed
reasonable because it still seemed to deal with my concern, and
that of several committee members, that there not be a direct
trailway through the south end of the park that would be used
primarily for access to the school. I would prefer one of these
entry points because of this concern. If it is decided that a
southwest entry to the park is necessary, S would suggest that the
entry be kept unobtrusive by using an easement of no more than
twenty feet in width and routing the trail in such a way that it
would not be attractive as a transportation route between the
neighborhood and the school. I agree with the consultant's
conclusion that the two lots in the southwest corner should not be
used for parking and that they are not really suitable for
development as a neighborhood park.
��,
An Equal Opportunity Employer
On the issue of vegetative management, it appears that some
difficult decisions must be made. After listening to the
consultants' explanation of the problem, I personally feel that a
long term effort to reduce the Buckthorn and restore other species
is the way to go. This may be expensive and require a great deal
of effort, but I think the future of the woods as an attractive
natural area depends on it. The whole master plan is based on the
premise that the area will be managed to preserve its natural
characteristics.
The proposed additions to the park, while not directly related to
the grant requirements, would certainly complement the existing
park area, provide additional buffer between the park and future
residential development, provide opportunities for restoring some
of the original vegetation types and provide for some of the more
active recreation uses that are likely to be needed in the future.
On the issue of fencing I think the master plan suggests a prudent
approach to what could be a controversial and expensive project.
While I am not usually a big proponent of fencing parks, in this
particular case some good arguements can be made for the possible
future need for fencing. At this time, however, it is probably
reasonable to direct funding resources toward other high priority
items, such as vegetative management and land acquisition, rather
than immediately fencing the area.
In summary, the proposed master plan for Carroll's Woods appears to
be consistent with the requirements of the grant agreement and, if
adopted, would establish needed guidelines for the future
development and management of the park. While I still have some
concern about the development of a southwest entry point, this
concern can be eliminated by taking steps to ensure that the trail
will not be used in the future as a traffic route between the
school and residential area. This concern should not detract,
however, from the overall importance and value of the master plan.
I think that city officials, your consultants and the citizens who
participated in the master planning process have done a fine job in
planning for the future of Carroll's Woods.
Finally, I want to compliment the City of Rosemount for its
decision to undertake such a comprehensive master planning project.
It is an effort that, I believe, has already proven its worth and
will continue to pay dividends into the future. I also want to
thank you for your efforts to keep me informed during the planning
process.
Sincerely,
Wayne GSames, Director
Outdoor Recreation Grants Program
Master Plan for Carrolls Woods Nature Area V
Planning Overview
In early 1991 the City of Rosemount undertook this master
planning study for Carrolls Woods Nature Area to define
its long-term purpose and objectives for development.
To accomplish this task, the City:
• appointed an ad hoc advisory committee of local
citizens to oversee the development of a master plan
for the park.
• hired the firm of Brauer & Associates, Ltd. to facilitate
discussion and develop a park master plan document.
The master plan document consists of the following major
components:
• Development Program: defines the park's general
purpose and identifies the major issues affecting its
future development.
• Alternative Concepts: illustrate a number of schematic
designs and physical relationships in response to the
development program.
• Site Inventory: identifies the site's existing physical
characteristics such as soils, slopes, drainage patterns,
etc.
• Site Analysis: makes judgements about the site and
identifies the site's opportunities and constraints for
development.
• Site Master Plan: is an outgrowth of the accepted
concept plan and represents the design solution that
best responds to the development program and site
inventory/analysis information.
• Vegetation Management Program: identifies the key
Carrolls Woods Nature Area
management objectives to assure long term ecological
diversity and integrity.
• Wildlife Habitat Program: identifies the key
management objectives to assure that the needs of
wildlife are met.
• Cost Estimate and General Phasing Program: projects
the anticipated costs to develop the park and establishes
a general phasing program.
• Education and Interpretive Program: identifies key
objectives of education and interpretive programs.
• Advisory Committee: defines the critical role the
advisory committee will play in overseeing the
development of the park.
The findings related to each of these components are
summarized in the forthcoming text.
Development Program
The Advisory Committee defined during focus meetings
the heritage and general purpose of Carrolls Woods
Nature Area and identified the major issues affecting its
future development. These items make up the
development program.
The development program is important because it provides
the direction and basis for the entire master planning
process.
LAWCON Grant
Carroll's Woods Park was acquired by the City of
Rosemount in 1975 through the State of Minnesota's
Outdoor Recreation Grant Program (LAWCON).
City of Rosemount
According to the original grant application, the intent of
the project was to "protect (from development) a natural,
wooded area within a growing part of the metropolitan
area" and to "provide some outdoor recreational and
outdoor educational opportunities for the citizens of
Rosemount."
In subsequent years the City applied for a number of
revisions and amendments to the original grant.
I AWCON, in most cases, granted these requests.
Since the original grant was obtained in 1975, the City has
created some trails and removed many dead American
Elms from the property. There has been no other
substantial development.
Wayne Sames, Director of the Outdoor Recreation Grant
Program (Community Development Division of the
Minnesota Department of Trade and Economic
Development) represented the State in interpreting the
provisions of the various grant application. Under his
interpretation, the current level of development was
considered to be within the guidelines and general
parameters established as part of the original grant
application and subsequent amendments.
With respect to future development, Mr. Sames indicated
that, under the State's interpretation, the park should: a)
continue to focus on the preservation of the resource and
b) provide passive recreational opportunities, such as
nature observation, educational programs, walking trails,
benches, etc. for the citizens to enjoy.
General Purpose(s) Of The Park
Given their understanding of the park's history and what it
means to the community, the Advisory Committee was
asked to identify what they considered to be the general
purpose(s) of the park:
Conservation and Preservation: to protect the site and
natural environment from encroaching development.
Passive Recreation to provide opportunities for passive
recreational activities such as:
• walking/hiking (accessible for the handicapped)
• nature/wildlife study
• family and individual "quiet space"
• informal cross-country skiing/snow-shoeing (groomed
for one track of skiing only)
Interpretation and Education: to provide opportunities for
education and interpretation without jeopardizing the
park's natural character. The City and School District
should develop programs for a variety of potential users
groups, including:
• school children of all age groups.
• individuals and families.
• seniors and special populations.
Carrolls Woods Nature Area should allow "passive"
education so that an individual can gain knowledge in an
informal manner. This passive education would include
such things as interpretive signs, printed site maps as well
as informational brochures, etc.
General Issues Related To The
Parks's Future Development
Along with identifying the purpose(s) of the park, the
Advisory Committee also identified a number of needs to
address during the planning process. These included:
• a general inventory/identification of existing plant
communities and vegetation.
• a need for a vegetation management program.
• a need to provide wilMe habitat.
• a need for an interpretation program to identify and
describe the various plant communities and wildlife.
• a need to encourage the local school district and local
civic groups to participate in the development of a
comprehensive educational program to educate people
(of all ages) about plant communities and wildlife.
• the need to maintain some form of site access and-
control.
ndcontrol. Potential uses of Carrolls Woods Nature Area
which could damage it included: overuse of the park,
free -roaming domestic animals attacking wildlife,
motorized vehicles entering the park, and other
"nuisance" problems, such as kids starting campfires,
smoking, drinking, littering, etc. Uncontrolled access
also allows a convenient "thoroughfare" from the west
side of the park to the high school area.
• the need to define more clearly the purpose of the
internal traiil& The 'Committee expressed concerns
about the need to reduce the width of the trails, the
desire for woodchip trails, and limiting the grooming of
cross-country skiing trails.
the need 'for additional parking. The Committee
considered the parking lots for Schwarz Pond Park and
Carrolls Woods Nature Area City of Rosemount
2
Rosemount High School to be too far away and often
unavailable to potential users of Carrolls Woods Nature
Area.
• the need for additional site amenities such as benches,
signs, observation blinds, bridges, etc.
• the need to identify and capitalize on the opportunities
inherent in Carrolls Woods' proximity to Schwarz Pond
and Rosemount High School
• the need for neighborhood recreational facilities to
service the recreational needs of the neighborhoods to
the west and north of the park. Note: this was identified
within the overall park system plan for the City.
• the possibility of including a prairie preserve area within
the park.
• the need to address safety issues (personal and
physical).
Addressing these needs provides the direction and basis for
the entire master planning process.
Alternative Concepts
Three alternative concepts explored different boundaries
for Carrolls Woods Nature Area and illustrated different
management techniques and relationships between physical
uses of the site. These concepts respond to the issues
listed above in the Development Program.
Fgwes 1, 2, & 3 illustrate three alternative concepts for
the park.
After considerable debate, the Advisory Committee
selected Concept #3 (Figure 3) because it:
responded to the criteria as set forth in the
development program.
provided a visionary approach to the park's future
development.
• allowed for more diversity in plant communities and
wildlife species than the other concepts.
Based on these findings, Concept #3, along with the
development program, provided the basis for the continued
progress in the master planning process. Brauer &
Associates Ltd. used this concept to begin an inventory of
the study area, analyzing its opportunities and constraints
in light of the development program and finally to refine
the concept into a Site Master Plan.
Site Inventory
Site inventory identifies the existing characteristics of the
proposed park area (including geology, topography,
drainage, soils, and vegetation).
Based on Concept Plan #3, the study area breaks down
into four adjacent parcels of land. Rosemount currently
owns two and would have to acquire the other two parcels
through parkland dedication, direct purchase, and/or grant
money.
Figure 8 - Site Analysis identifies four parcels within the
study area:
• Parcel A: includes Carrolls Woods Nature Area as
defined by its current (1991) boundary (45 acres).
Acquired by the City through a LAWCON grant in
1976 for passive use, nature preservation and
environmental education.
• Parcel B: includes the part of Schwarz Pond Park
which lies west of the north -south asphalt trail (e.g.,
west of the existing ballfield). This would include the
pond itself (31 acres). The parcel is already owned by
the City.
• Parcel C. is an area which lies between Carrolls Woods
and an existing gasline easement north of the park. This
parcel is currently used for pasture land and is not
owned by the City (15 acres).
• Parcel D: is an area west of Schwarz Pond, north of
Parcel C, east of a dominant ridge line, and south of a
future collector street. This parcel is also currently used
for pasture land and is not owned by the City (7 acres).
Geology, Topography, and Drainage
Thousands of years ago the climate of Minnesota warmed
and the glacial ice which covered Rosemount began to
melt. As the glaciers receded northwards, they deposited
huge amounts of debris which had been carried in the ice.
The deposits of sand and gravel and boulders, often over
one hundred feet thick, are known as terminal moraine.
The topography of the terminal moraine is rolling with
steep hills, ridges, and landlocked depressions. Some level
areas do exist at the base of slopes, in saddles and
depressions, and on hilltops.
The slopes of Carrolls Woods are mostly hot, south-
southwest facing slopes. The Schwarz Pond parcel is a hot
Carrolls Woods Nature Area City of Rosemount
west -facing hillside. Parcel D has mostly north -facing
slopes and the most moderate topography. Parcel C is a
series of ridges running north to south with steepest slopes
facing east and west.
Glaciers determined the landscape of Carrolls Woods and
set up the drainage patterns which still exist today. Figure
4 - Dmimagie Paltems illustrates the site's current drainage
patterns. These patterns are critical to the formation of
soils and the subsequent development of plant
communities. In Figure 4 - Dndnage Pauems, the thick
dashed lines mark the high points of the property and the
boundaries of the watersheds. Water flows in opposite
directions on either side of these lines. It is interesting to
note the north -south pattern of ridges within the study area
which mark the direction of receding glaciers. Because of
the steep slopes of these ridges, the watersheds would tend
to drain rapidly after a heavy rain. Since the watersheds
are small, their lowpoints would not collect much runoff.
Even so, one would expect to find wetlands in the several
landlocked depressions on the property unless the soils are
porous.
Soils
After the glaciers melted, weathering forces began to act
upon the rock and debris left behind and started to form
soils. Soils and slopes are intrinsically related. Slopes
affect the degree of wind and water erosion, the rate at
which moisture is absorbed and retained, and finally in the
amount of sunlight reaching the ground. These factors in
tum affect the growth of vegetation and the subsequent
development of soil strata called a profile.
Any management program should begin with an
examination of the area's soil profiles. Soils offer an
explanation for existing plant communities and affect the
success of any planting restoration efforts.
Figure 5 - Slopes and Soils shows that the study area is
generally a dry site. No clay soils are present. Most of the
soils are sandy or silt loams with moderate to steep slopes.
This means water either runs off rapidly or percolates
through rapidly. The subsoils are usually composed of
several feet of sand and/or gravel. Depressions on the site
are silty loams and poorly drained; these soil types make
up a very small percentage of the total acres of the study
area.
Figure 6 - Soil ChanutoWd explains the possible uses of
each soil type found within the study area. The Dakota
County Soil Survey states that the hillsides of the study
area are generally most suited to woodland or prairie/
pasture/hay. Tilling is often difficult. The Soil
Conservation Service recommends using drought resistant
species on the most of the hillside soils.
Carrolls Woods Nature Area
Vegetation
150 years or so ago the Rosemount area was
predominantly oak savannah and prairie. Prairies are
communities dominated by grasses and forbes. Oak
savannahs consist of isolated oaks or small stands of oaks
surrounded by a sea of grasses and wildflowers. Both plant
communities are dependent on fire for continued existence.
The savannahs, with their open vistas and groves of
beautifully -formed craggy oaks, were particularly attractive
to European settlers who were reminded of the parklands
of their home countries. As the settlers turned the
savannahs into home sites and farms, they also suppressed
the fires which are so critical to the continued existence of
the prairie and oak savannah communities. In the absence
of fire, woodland species invaded uncultivated savannahs
and prairies. In the full sunlight between the established
Bur Oaks of the savannahs, Black Cherry, White Oak and
Red Oak sprouted and grew. Sun -loving shrubs such as
Hazelnut, Sumac, Gooseberry and Raspberry also invaded.
When wildfire was suppressed, American Elm, Boxelder,
Hackberry, Green Ash began to take hold. Under their
canopy, the more shade -tolerant shrub species such as
Elderberry, Dogwoods and perhaps Arrowwood and
Nannyberry Viburnums grew. Within 50 years of the
arrival of settlers, the savannahs and prairies of Rosemount
had changed dramatically.
In addition to suppressing fire, the European settlers also
brought with them plant diseases and non-native shrubs
and trees which sometimes out -competed native species.
25 years ago, American Elm probably.dominated the tree
canopy of Carrolls Woods. Since then almost all the
American. Elm has died of Dutch Elm disease and has left
the central portion of the 45 acre parcel with a very sparse
canopy of trees. Common Buckthorn (Rhamnus
cathartica), a particularly aggressive non-native shrub, has
invaded the property and has virtually taken over the
understory. Tartarian Honeysuckle and woody vines have
also been aggressive invaders. Fortunately in the last
decade the Tartarian Honeysuckle has died out because of
aphid attacks and concerned citizens of Rosemount cut and
reduced considerably the vines strangling many canopy
trees.
Today the canopy of trees in Carrolls Woods is composed
of the following species:
Boxelder (Acer negundo)
Green Ash (Fraxinus pennsylvanica)
Black Cherry (Prunus serotina)
Hackberry (Celtis occidentalis)
Red Oak (Quercus rubra)
Northern Pin Oak (Quercus ellipsoidalis)
Bur Oak (Quercus macrocarpa)
City of Rosemount
White Oak (Quercus alba)
Silver Maple (Acer saccharinum)
Cottonwood (Populus deltoides)
Aspen (Populus sp.)
Boxelder and Green Ash are the most common trees of
the uplands. Black Cherry and oaks are also quite
prevalent with some beautiful stands of mature individuals
scattered throughout the site. Several Silver Maple
dominate the moist lowlands of the site. One enormous
Cottonwood grows along the trail which runs across the
southern edge of the property. Small mature stands of
aspen are scattered throughout the uplands. Aspen are
short-lived in a forest because they are intolerant of shade.
They may seed in or root sucker into openings, but as the
canopy closes in, they will begin to die out.
Ecologists and foresters examine the understory of a forest
to determine the future of its canopy. The understory of
Carrolls Woods and the forest west of Schwarz Pond has
a rather depressing story to tell. Barring human
intervention or natural catastrophe (fire), Carrolls Woods
will succeed to an almost pure stand of impenetrable
Buckthorn with some Boxelder as the existing canopy trees
die out. There are almost no seedlings of oak or cherry
present in the 45 acres except in small openings with full
sun and no Buckthorn. Occasional saplings of Green Ash
and Hackberry are present but even they are rare. Shrub
species other than Buckthorn are also uncommon-
Occasional
ncommonOccasional Elderberry and Prickly Ash are scattered
throughout the site.
The ground layer of Parcel A (Carrous Woods) shows
quite a diversity. Although not closely inventoried, Jack -
in -the -Pulpit, Trillium, ferns and mosses are present in
various areas of the site. These species indicate moist or
mesic microclimate conditions and need shade to survive.
Nettles, gooseberry, raspberry and seedlings of the ever-
present Buckthorn are common along paths and in
openings where there is full sunlight.
Parcel B (part of Schwarz Pond Park ) consists of a hot
west -facing slope which leads down to the pond. The slope
is covered by a well-established canopy of Northern Pin
Oak, Red Oak, White Oak and Black Cherry with a dense
understory of Buckthorn. The eastern and northern shores
of the pond are primarily open with young successional
woodlands of pioneering species (aspen, Boxelder, and
willow) and stands of sumac.
Parcel C is a open, rolling site with one very small remnant
of prairie. The topography is spectacular and interesting.
It is currently used as sheep pasture.
Parcel D is a open, rolling site with some fairly level
topography. It too is used for sheep pasture.
General Perceptions of Vegetation
It is clear that Rosemount citizens are very fond and
protective of Carrolls Woods and the Schwarz Pond
property. Most people enjoy strolling under a lush, cool
canopy of trees in the summer. They appreciate the beauty
of the woods as they are now and are more interested in
sensory experiences rather than how "pure" the ecological
communities are.
Ecologists, on the other hand, see Carrolls Woods through
different eyes: as a forest of mixed hardwoods considerably
degraded by Buckthorn and with a limited future.
The short-term management objectives for the two views
of the woods are opposite; the first demands little
disturbance of existing conditions, the second demands
heavy intervention and manipulation to maintain ecological
diversity.
Left on its current course, the canopy of mixed hardwoods
will continue to die out and be replaced by Buckthorn
which effectively shades out any tree seedling or sapling.
In the not -to -distant future, Carrolls Woods will evolve into
a dramatically different place: a sea of Buckthorn. The
trails will become corridors through a dense mass of 20-
25 foot Buckthorn with no cool shade and no sensory
diversity. At this point in time the two opposite
approaches for forest management will become similar,
demanding intense intervention to recreate the canopy.
The perceptions of the public, rather than the ecologists,
are critical to the acceptance of the Master Plan for
Carrolls Woods Nature Area. Brauer & Associates Ltd.
recognized this and inventoried the vegetation of the four
parcels in a manner which would address these
perceptions. The wooded areas of the study site were
divided into six forest types (see Figure 7• Vegetation). Each
type has a different type of canopy and understory and very
different visual and sensory qualities.
Site Analysis
Site analysis uses inventory information to make
judgements about the site. Site analysis identifies
opportunities and constraints for development.
Access and ControL• Users of Carrolls Woods currently
enter the 45 acre parcel from several points. The asphalt
trail running "along the eastern border is the most
sanctioned entry point. Several trails of varying widths
enter the woods off this trail. Another main entry point is
Carrolls Woods Nature Area City of Rosemount
19
at the bottom of a steep hill in the southeast comer of the
property. There are three points of entry along the west
border. The Advisory Committee felt strongly that the
number of access points into Carrolls Woods Nature Area
be limited.
The Committee also felt that entry points will be needed
on the north, west, and east side of the property.
Internal Trail System: Many trails crisscross Carrolls
Woods. They vary in width, degree of steepness, and
quality of the surface. The Committee did not want to
create new trails unless necessary and felt some trails
should be eliminated or realigned.
Currently teens often use a trail along the southern edge of
the woods as a way to get to and from Rosemount High
School. As residential development on the west side of the
park continues, use of this trail will likely increase. The
Committee felt that they did not want Carrolls Woods
Nature Area to be used merely as a shortcut from one
point to another.
Figure 8. Site Analysis highlights those trails which should
be eliminated because they are redundant, too steep, too
wet, or because they serve undesirable access points.
Site Amenities: There are no benches, signs, or other site
amenities in Carrolls Woods. There are many
opportunities for these built facilities which should be
added once restoration efforts for the plant communities
are underway.
Parking: Visitors coming to Carrolls Woods by car must
use the parking lots for Rosemount High School or
Schwarz Pond Park. These are so far away from the
woods that it takes a good walk just to get to the park.
Also the lots are often full.
Topography and existing development around the
perimeter of the site presents a challenge to the designer
of a parking lot which requires level grades. Parcel D has
the most level grades for parking. The two lots owned by
the City in the southwest comer are inadequate in size to
serve the future parking needs of the park.
Neighborhood Recreational Facilities: Parcel D is an
open, rolling area with some fairly level topography. It will
be immediately adjacent to a proposed collector street. In
the near future the areas north and west of this parcel will
likely be developed for residential housing. These
communities will need neighborhood recreational facilities
within walking and biking distance. Parcel D has the
acreage and enough level topography for these recreational
facilities.
Schwarz Pond: The pond within Schwarz Pond Park is a
significant natural area and has value as wildlife habitat.
It has limited value as a recreational lake. The woodland
east of the pond has many lovely oaks and cherry trees.
This area should be included in the Carrolls Woods Nature
Area.
Parcel C: With its dramatic topography and open vistas
and its existing use as a pasture, this area is perfect for
prairie and oak savannah restoration. Near the northern
border of Carrolls Woods is a mature, beautifully -formed
Bur Oak and a nice stand of smaller Bur Oaks. The form
of these trees indicates the area could have once been a
savannah.
Woodland Vegetation: the inventory of vegetation in the
study area indicated six types of forest. Each type will have
a different management approach (defined in the
Vegetation Management Program). Control of Buckthorn
will be critical in all areas.
Fguue & SiteAnalp* simplifies the areas of forest for the
purpose of management.
• Degraded Woods: sparse canopy; isolated mature trees
@ 150-200+ feet apart. Understory is a impenetrable
wall of Buckthorn.
• Open Canopy: mature trees are much more common
and closer together. The understory is still fairly dense
Buckthorn.
• Pleasant Woods: mature trees form a good canopy with
some Buckthorn in the understory.
• Lowland forest: these small areas are disturbed
frequently by groundwater or wet soil conditions.
Gigantic Silver Maples and Cottonwoods are common
with an ground layer of nettles. .,
• Successional: young trees, dense understory with a
variety of species.
Master Plan
The Master Plan is a direct outgrowth of the accepted
Concept Plan and represents the design solution that best
responds to the development program and the site
inventory and analysis.
Fgune 9. MasterPlan illustrates the results of the planning
process for Carrolls Woods Nature Area. This graphic:
• clearly defines the park's property boundary (consistent
with Concept Plan #3) to ensure diversity of plant
communities and wildlife habitat.
locates and sizes all appropriate facilities and site
amenities.
Carrolls Woods Nature Area City of Rosemount
• establishes appropriate plant communities which are the
basis for wildlife habitat.
The following tem describes each physical element of the
Master Plan and explains the reasoning behind the design.
It is clear that Rosemount citizens feel the need for an
undeveloped area where they can stroll and appreciate the
beauty of nature. A number of recent studies have
documented this need, which is likely to become more
acute as the community continues to grow. Likewise,
Rosemount schools will continue to need a place for
environmental education and interpretation. It is important
to recognize that Carrolls Woods Nature Area is different
from other community -type parks: its environment is more
fragile and complex. Human activity and intervention can
easily change the character and overall quality of this
natural area.
To insure the long-term preservation of Carrolls Woods
Nature Area, it will be critical to protect the park from
the pressures associated with suburban development.
These pressures raise the issue of control and access.
Currently Carrolls Woods has an unfenced perimeter.
Although it is not easy for the average citizen to reach the
park (parking is far away), it is easy to enter the woods at
any number of locations. There is no perceived
stewardship of the park. This lack of control works fairly
well with the existing level of use of the park and with the
land uses which currently surround the property, i.e.
farmland to the west and north, the high school to the east,
and homes to the south. Without a doubt, this casual
approach to control is ideal and very appropriate in the
near future while the community begins managing the plant
communities of Carrolls Woods Nature Area and
developmental pressures around the park remain limited.
However times are changing in Rosemount. Within the
nem decade residential development will occur to the north
and west of the park. As undeveloped land disappears
from the community, citizens will have a greater desire to
spend time in a nature preserve. The City will want to
make access to the park as a community resource easier
for the average citizen by providing parking and trails.
Undesirable activities within the park will increase as the
population of Rosemount grows. Free -roaming cats and
dogs will disturb wildlife. Small footpaths begin to increase
in width as people make their own shortcuts. Students will
cut through the park to get to the high school.
Unauthorized uses (parties, campfires) and nuisance and
vandalism problems tend to increase in areas that the
public does not perceive as controlled. All these pressures
will degrade the woods as a natural area. At some point in
the future Carrolls Woods Nature Area will likely have to
be protected by some means other than the goodwill of
Rosemount citizens, namely a fence around the perimeter.
This circumstance is certainly not unique to this park.
Virtually all nature centers with limited acreage in the
Twin Cities metropolitan area fence their property. The
fence becomes not only a physical barrier but a
psychological one as well. It makes a statement to the
community that the area is special and needs protection.
By limiting the number of gates, the City can control the
hours and season of use (if desired) and most undesirable
activities. Gates are also opportune places to present rules
and interpretive information. Fences discourage
unauthorized uses, encroachment, and trespassing on
private property.,
Specifically, the fence is intended to:
• clearly define the parks perimeter and make a
statement as to its intended purpose.
• protect the park from developmental encroachment.
• restrict site access to pedestrians and maintenance
vehicles and thereby limit trails.
• control free -roaming domestic animals.
• prevent motorized vehicles and bicycles from entering
the park.
• control "nuisance" problems, such as kids starting
campfires, smoking, drinking, littering, etc.
• prevent the park from becoming a convenient
"thoroughfare" between the developing part of the City
to the west and north of the park and the schools and
major community center.
After considerable discussion and debate, the Advisory
Committee recognized that the need for a fence may
become a reality at some point in the park's future and
that a fence should be included in the Master Plan.
However, the Committee also felt that there is no
compelling reason at this point to have the fence high on
the priority list for development. Instead, the Advisory
Committee should review on a periodic basis the need for
a fence, along with other development considerations. The
Committee should use as criteria the items listed above to
determine whether or not the fence is needed. If the site
begins to degrade from unauthorized uses and these uses
cannot be effectively controlled by other means, the City
will have to consider strongly installing the fence to protect
the site.
Initial reactions to the idea of a fence around the Carrolls
Woods Nature Area may be that it is intimidating,
unnecessary, and ugly. However, this does not have to be
Carrolls Woods Nature Area City of Rosemount
the case. If installed properly, a fence can be relatively
unnoticeable. Vegetation will screen it. Psychologically, the
fence becomes a barrier to the human world that, in the
not so distant future, will encircle the park. Those who are
involved in the park's future development should go out to
any one of a number of fenced nature areas within the
metropolitan area and see for themselves how little a fence
affects the park's atmosphere.
Should a fence become necessary in the future, it should be
six foot in height. Galvanized chainlink fence of a suitable
commercial grade is the most commonly used material
because it is relatively economical to construct and
reasonably durable.
As the Master Plan illustrates, the fence is intended to
essentially follow the park's property boundary. To limit
its visual impact and make it as unobtrusive as possible,
the fence should be set back 15 to 20 feet from the
property line and be screened by surrounding vegetation.
This is particularly true in the more heavily wooded areas
of the site, where the fence's alignment will be dictated as
much by the existing vegetation as by the property
boundary. Care should be taken during the fence's
installation to disturb the existing vegetation as little as
possible. Installing the fence in the late fall when plant life
is largely dormant and avoiding existing trees will minimise
damage to the park. In open areas planting vines and
shrubbery will help screen the fence from view.
In areas where the fence will be adjacent to existing
residential properties, the City should make homeowners
aware of the fence's proposed alignment prior to its
installation. Some homeowners may prefer the fence along
the property line rather than set back and screened from
view.
The Master Plan identifies three pedestrian gates to
provide access into the park.
The tum -style type, pedestrian -only gate in the southeast
comer of the site will serve the already -developed
residential "core" of the City as well as the school. This
entrance should be very simple and unobtrusive, with an
asphalt trail providing access from the existing roadway
down to the gate.
The access shown on the northwest comer of the site will
serve future residential areas to the west and northwest of
the site. This gate should also be a tum -style, pedestrian -
only gate. To access the gate from the residential street
west of the park, the City needs to acquire a 25-30' wide
easement to allow for grading, screening and building a
trail.
The main entrance gate on the north side of the site will
serve not only those walking to the site but school buses
and those driving to the site from other areas of the
community. This entrance should be simple and natural in
design and make a statement that the visitor is entering the
nature area and a protected environment. This gate should
be limited to pedestrians. A gathering area outside the gate
should accommodate a group of 25 people (a class of
students). This area will include benches and perhaps a
kiosk. Inside the gate, a kiosk provides visitors with a map
of the area and a brief description of what might be seen.
The displays should include photos, graphics, and written
text to describe and illustrate the park's features. The kiosk
should have a leaflet box to dispense park maps/guides.
The Master Plan includes a number of gates for
maintenance vehicles. The primary access is near the main
entrance gate on the north side of the park. This access
should serve most maintenance needs once the park is fully
developed. A second access is shown near the pedestrian
entrance on the northwest. A third access is shown near
the existing hockey rink on the southeast side of the site.
This access will probably serve as the primary maintenance
access until the park becomes more fully developed. This
gate can be opened in October for participants in the
Haunted Woods program.
The Advisory Committee debated at length the issue of
whether or not to provide a pedestrian access in the
southwest comer of the site. After lengthy discussions, the
majority of Committee felt that a gate, in the northwest
would better serve the park because:
• it was more centrally located to serve the residential
areas to the west as well as the northwest.
• it reduced the likelihood of the park being used as a
"thoroughfare" from the western part of the community
to the high school and other community areas east of
the park. I _ .
Since no pedestrian access is planned for the southwest
comer of the site, the park dedication land currently owned
by the City adjacent to the park is of little future value (for
the purpose of accessing the park) and could be, at the
discretion of the City Council, sold -off for residential
development.
The Advisory Committee also discussed the twenty foot
easement near the southeast comer of the site. Given its
relatively steep grades and the current lack of use as an
access to the park, the Advisory Committee felt no action
was necessary at this time. However, the members of the
Committee did agree that the issue should be reviewed
again prior to installing the fence, should the fence become
a reality in the future.
Internal Trail System
An internal trail system which meanders through the park
will move people through the nature area with a minimum
Carrolls Woods Nature Area City of Rosemount
a
impact to the environment and yet insure that they receive
a quality outdoor experience. Although the primary
objective of the trails is to link together the various plant
communities, the system should also be developed to take
advantage of the varying topography, views, and vistas. The
trails should provide visitors with a variety of perspectives
and experiences.
Figure Ia- Typical Trad Dass -Section for Canvas Woods
Nature Area shows the suggested design for internal trails.
In order to keep the experience of the woods as intimate
as possible, the width of the trail should be six feet with a
one foot maintenance strip on each side. The surfacing
material should be:
compacted crushed aggregate (suitable for handicap
accessibility) on the primary loop within the wooded
and prairie/savanna areas.
• woodchips on the auxiliary and secondary trails within
the wooded areas.
mowed grass on the auxiliary and secondary trails
within the prairie/savanna areas.
Because one of the primary development objectives is to
limit disruption to the existing mature vegetation, the
Master Plan uses existing trails within the park as much as
possible. However, some changes will be needed where
existing trails do not serve a future purpose and/or where
their grades are excessive. In some cases, trails will be
eliminated because they serve undesirable access points.
Since the existing trials vary from four to twelve feet in
width, they will require some reworking, much of which
can begin immediately. Also, even though the trails shown
on the Master Plan may follow existing alignments, they
may need redesigning to make sure that they are safe and
maintainable.
The new trails shown on the master plan supplement the
existing trails. All of the trail alignments, both old and
new, should give the user a quality experience of the park
with many options for routes to walk. The exact location
of each trail must be established in the field during design
development (i.e. the "next step" in the planning process)
to take advantage of the opportunities afforded by the site.
In other words, the trail alignments as illustrated on the
Master Plan should be considered approximate and not
absolute.
As with the existing trails, new trials should be designed to
make sure that they are safe and maintainable.
Carrolls Woods Nature Area should be a community
resource in the winter as well as in the spring, summer and
fall. Snow and ice can be barriers to using the trails. The
Advisory Committee felt that a single groomed track for
cross-country skiing would allow people to experience the
Carrolls Woods Nature Area
woods in winter and would not detract from the quality of
the environment. A single pass through the woods by a
snowmobile trailing a pair of weighted skis would create a
narrow trail for skierswhich would not damage surrounding
vegetation.
Site Amenities
Enhancing the perceptions and experiences of park visitors
through the careful use and placement of site amenities is
important and will greatly affect the overall success of the
park as a public resource. Site amenities are the built
features which increase the comfort/access of the park
users. As with the trial alignments, the exact locations of
the various site amenities must be established in the field
during design development to take advantage of the
opportunities afforded by the site.
All of the site amenities should be natural and simple in
design and as much as possible blend into the environment
that surrounds them.
Interpretive Nodes and Signs: interpretive nodes are
places along the trail with low profile kiosks. These kiosks
have interpretive panels and exhibits which are fun and
easy to read with good graphics and minimal text.
Interpretive nodes are typically located near benches and
other site amenities (i.e. decks, docks, etc.). Located
along the trails, unobtrusive interpretive signs will identify
the various plant communities and wildlife species and
augment the interpretive nodes.
Benches: should be provided to take advantage of different
views and site features, ranging from quiet, intimate spots
to wide open vistas. Again, benches can be installed at
interpretive nodes if appropriate.
A Floating Boardwalk: located in the wet prairie area gives
park users an close -hand experience of the tall grasses and
forbes of the wet prairie.
Environmental Education Dodc provides an educational
opportunity for schoolchildren so that they can study pond
life and take water samples, etc. In addition, the shop
students from the local schools could help construct the
dock as part of their classes.
Pond Overlook Doc]- provides park users with a pleasant
place to sit and view the pond. Two benches allow seating.
Pond Observation Blind: provides park users with an
opportunity to view waterfowl activities. If properly
designed, the blind hides people whose presence and
movements normally scare the waterfowl away. The blind
is on the edge of the pond and surrounded by vegetation
to help screen it from view. An elevated catwalk from high
ground provides an interesting access to the blind.
City of Rosemount
Wooden Bridge Across Woodland Pothole: is a simple
structure with a railing that crosses the woodland pothole
at a narrow point.
"Lookout' Tower. gives park users a birds eye view of the
area and is another opportunity for a visitor to observe
nature in relative anonymity. A height of thirty feet should
elevate the tower platform above most of the understory
trees.
Woodland Dedc is another simple structure with benches
designed for resting and observing nature.
Cottage House for Interpretive Displays, Storage,
Meetings, Etc.: is a simple building to serve the listed uses.
The building should be sited near the main entrance gate
at the edge of the savannah. It should have a low profile
and use natural materials to blend into the surroundings.
A patio outside the building allows visitors a place to sit
and observe the prairie.
Entrance Drive and Parking
Since the entrance drive is the first contact that visitors
have with the park, it should be located in a manner which
compliments the existing topography. The entrance drive
will tie into a future collector street which is likely to be
developed north of Schwarz Pond Park.
The parking lot at the end of the entrance road should be
sized to prevent overuse of the park but large enough to
allow a bus to turn around. Ideally, the lot should be
paved with asphalt to minimize long-term maintenance and
dust.
Since the entrance drive and lot are outside the nature
area itself, they will technically be part of Schwarz Pond
Park. Users of the picnic areas on the west end of the
park will probably park in the lot. A lot for35 to 50
spaces plus several bus parking stalls will probably be
sufficient to satisfy the parking needs of the users of both
the nature area and Schwarz Pond Park. However, as
actual design and construction of the lot and entrance road
become reality, the City should closely examine potential
demand for parking and size the lot accordingly.
Neighborhood Recreational Facilities
The city-wide park system study identified the need for
neighborhood recreational facilities for this area of the
community. Parcel D is an open, rolling area with some
fairly level topography and is adjacent to the proposed
collector street. Parcel D is the best site within the study
area for neighborhood recreational facilities.
Carrolls Woods Nature Area
/^
Since it is the policy of the City to include input from area
residents when determining what recreational features will
be in the park, the facilities shown on the plan are for
reference only and need to be confirmed (or changed)
when development actually occurs.
These recreational facilities should be connected by trails
to the community -wide trail system.
Schwarz Pond Park
The pond within Schwarz Pond Park is a significant natural
area which could add greatly to the diversity of plant and
wildlife habitat within the park. The area east of the pond
can provide excellent waterfowl nesting habitat if current
mowing practices are discontinued and the City restored
the area to prairie. Fencing (should it become necessary)
and wildlife plantings along the asphalt trail would keep
domestic animals from disturbing nesting areas.
The wooded area, as a beautiful natural area west of the
pond, should be included and managed as part of the park.
Its location next to the pond enhances the wildlife value of
both areas.
The pond is a ecological community which has important
education and interpretive possibilities. The City or
Science Department of the Rosemount High School should
monitor the water quality of the pond to protect its
integrity as a resource.
The Master Plan shows a number of amenities within
Schwarz Pond Park and outside the nature area. These
amenities include two scenic overlooks and a number of
picnic areas near the parking lot. The overlooks should be
mowed areas or decks with benches overlooking the pond.
The picnic areas should also be simple in design, with a
number of picnic table and grills and perhaps a small -
group picnic shelter.
External Trails
External trails provide access to park entrances and play
an important role in how well the park ultimately serves
the residents of Rosemount. The three entrance gates
should tie into the community -wide trail system which is
defined within the City's Comprehensive Park Plan and
Development Guide.
The existing asphalt trails on the east side of Carrolls
Woods and Schwarz Pond will ultimately be outside the
(fenced) nature area.
The trail to the southwest entrance can easily tie into the
City of Rosemount
already established community trail along the 142nd Street
West.
The trail to the northwest gate and main entrance gate are
important. Since no access is planned for the southwest
corner of the park, the residential areas to the west need
a safe means to get to the northwest entrance. Likewise,
the communitytrail built along the future collector street
north of the park will be an important link to the
communities to the north and northwest of the site.
The Advisory Committee and City should review access
concerns periodically and in conjunction with planned
development in the area to insure that trail access
opportunities are not lost along the way.
Vegetation Management Program
The Vegetation Management Program identifies the
management approaches and procedures to guarantee the
ecological diversity of the Carrolls Woods Nature Area so
that it will be a treasure and resource for future
generations.
In order to maintain long-term ecological diversity and
integrity, the wooded portions of the park must be
managed and improved and the open areas need to be
restored to prairie or savannah.
Vegetation management programs can be geared to create
five different types of sensory experiences of Carrolls
Woods Nature Area and adjacent parcels. These sensory
experiences also represent different ecological
communities.
Dense canopy: 75%-95% overstory coverage with sparse
understory (relatively open). Sensory experience: lush,
shady, cool. Open feeling under a ceiling of trees. Long
views through woods. This type of feeling is most common
in a lowland forest or in a mature Sugar Maple -Basswood
forest. The latter requires moist (not wet), protected and
semi -shaded conditions. Neither Sugar Maple or Basswood
grows naturally on the site; introducing these species would
create an anomaly or artificial condition. It might be
beneficial to attempt to create this woodland community
for an environmental education program.
Moderate canopy. 40%-60% overstory coverage with
moderately ,dense understory. Cool shade dappled by
sunlight, limited views. Common in a mixed hardwood
forest. This sensory experience is probably most popular
among Rosemount citizens and already exists along most
of the trails and along the northern edge of Carrolls
Woods.
Sparse canopy: less than 15% overstory coverage and dense
understory. Without fire, this community is dominated by
aggressive pioneering plants. The sensory experience in
summer is hot, walled -in, transitional, young, not as
appealing as types listed above. This condition is frequent
in the center portion of the site with dense Buckthorn.
Savannah: mostly open with occasional spreading individual
trees or small stands of stunted trees. Intense sunlight with
pockets of shade. Bright, hot, open, windy in summer. In
winter, savannahs feel exposed and cold; snow melts away
quickly especially on south -facing slopes. Attention focuses
on landform and trees. Oak savannahs are rare plant
communities today.
Prairie: open, hot often uncomfortable in the summer
unless there is a good breeze. Pleasant in spring and fall.
Windy and unprotected in winter; snow disappears quickly
on south -facing slopes. Attention focuses on landform, the
texture and color of grasses, the washes of color from
wildflowers. Prairies can grow in a variety of situations:
from wet, poorly drained areas to dry, barren hilltops.
Available water and the depth of topsoils determine which
species of grasses and wildflowers will best grow.
Existing Site Opportunities. The two wooded parcels
within the study area (Parcels A & B) currently provide
opportunities for nature lovers. to enjoy two types of
Minnesota forests: the dry upland forests of mixed
hardwoods (oak, cherry, ash, Hackberry) and lowland
forest of boxelder, cottonwood and silver maple. Parcel A
(Carrolls Woods) has one north -facing slope which could
provide the cooler microclimate conditions needed for a
moist upland forest (Sugar Maple -Basswood).
Parcel C is an open, rolling site with one very small
remnant of prairie. The topography of this parcel is
spectacular and interesting and has great potential for
prairie and oak savannah restoration. If possible,
Rosemount should acquire enough land to control the
viewshed (i.e. to the tops of ridge lines) and should also
consider scenic easements.
Aesthetics suggest softening the straight line boundaries
between woods and pasture (prairie) that exist along the
northern boundary of Parcel A (Carrolls Woods) and along
the eastern border of Parcel B (Schwarz Pond Park ). For
this reason, some of the oak woods along the western edge
of Parcel B be restored to savannah.
Since savannah is more easily restored than recreated,
Rosemount should treasure the savannah type oaks (Le.
100-150 year old Bur Oaks with rounded canopies) which
exist within the study area.
Management Objectives. The management objective of
woodland management within the nature area is to
maintain diversity within the existing woodland
communities. This will insure that the future generations
Carrolls Woods Nature Area City of Rosemount
will be able to enjoy a forest of trees rather than a
monoculture of Buckthorn.
Woodland management will be a tricky issue for the City.
The Buckthorn infestation is so severe that removing it will
devastate the forest for a few years until other species take
hold. Unfortunately, there is no alternative if Rosemount
citizens want to achieve the long-term goal for the park
with ecological diversity. Phasing and public
awareness/education will be critical to public's
understanding of what is happening within the park and to
their support of management efforts.
The restoration of prairie and oak savannah should not
create the same concerns as the woodland management
program. The proposed sites for these communities are
currently in pasture and restoration efforts will not appear
to change the area so dramatically. Burning may present
some problems, but again publicity and sensible scheduling
will limit public concern.
Vegetation Management Plan
Figure 11 - Vegetation Management divides the park into
several zones. Each zone is described by:
• a letter/number code.
• a phase number.
• an approximate acreage figure.
The first part of the code describes the ecological
community (e.g. WO = Woodland - Mixed Hardwood, P
= Prairie, S = Savannah, etc.). The second part of the
code is an alphabetical letter which describes the method
of restoring or managing the ecological zone. These
methods are described in detail below. The third part of
the code is a number which describes the priority of the
zone for management/restoration. Zone 1 is the highest
priority within a particular ecological community and Zone
9 is the lowest. Ytg=12 - Vegetation Management Phasing
Program describes phasing in more detail.
Prairie Areas (Method A or P -A-#)
The City should hire a firm specializing in prairie
restorations such as Prairie Restorations of Zimmerman,
Minnesota or Prairie Nursery of Winona, Minnesota.
These firms offer advice and a range of services including
burning and planting. Make sure the chosen firm uses
prairie seed collected within a 200 mile radius of
Rosemount. Non-native seeds can be aggressive, resulting
in one or two species dominating the site.
Can-olls Woods Nature Area
1-7
Mow fire breaks around the perimeter of the future prairie
areas.
The experts from the prairie restoration firms will
recommend the best technique for restoring the prairie
grasses and forbes appropriate to each particular microlite.
The nursery may recommend burning the entire prairie -
designated area to see what surprises the seed bank in the
soil holds. Prairie seed can lie dormant for years in the
soil. Next, the experts may recommend one or two general
or local applications of Round -Up. This herbicide will kill
all vegetation. The next step is to use a Truax Drill to
plant seeds of prairie grasses. The following year the
restoration firm may mow and plant by hand forbes or
wildflowers (1000/acre).
In the beginning a prairie should be burned every year in
order to eliminate weeds and the woody plant materials
which naturally invade an open site. Burning also creates
spectacular wildflower displays. Once established, a prairie
should be burned every 3-5 years.
Recreated Oak Savannah (Method A or S-A-#)
In these designated savannah areas, mow 10-15 foot fire
breaks around the edges to prevent the fire from jumping
into the adjacent woods.
Hire a prairie restoration firm. Restore prairie. Once the
prairie community is established, tree spade in small Bur
Oaks ( 2• -3" diameter at breast height). Plant the Bur
Oaks in clusters or as isolated species 150-200 feet apart.
The City can reduce costs by transplanting Bur Oaks from
other City property or by donation from private property.
This transplanting can occur over a period of years.
Examine the transplanted trees after one season. If they
are doing well, leave them be. If they appear sick, cut the
trunks off around 6-12 inches above ground. The Bur
Oaks should sprout from the base. After 2-3 years, select
a main leader and prune off the rest.
The Bur Oaks seedlings will need Tubex Tree Shelters
(@$5.00 apiece installed) to protect them from deer
browsing.
Initially, a savannah should be burned annually. The young
Bur Oaks need protection from the heat of the fire. Mow
a 16 foot diameter circle around each oak to protect it
from damage.
Once sufficient shade is established, plant the forbes and
grasses unique to a savannah community.
City of Rosemount
Restored Oak Savannahs (Method B or S -B-#)
Oak Savannahs are more easily restored than created from
scratch. A few savannah type trees exist along the
northern edge of the Carrolls Wood. These are Bur Oaks
with well -formed rounded canopies; they look like they
have always grown in the open rather than in cramped
forest conditions. Mature Bur Oak have thick corky bark
which makes them resistant to quick ground fires common
to prairies.
In the designated savannah areas, mow 10-15 foot fire
breaks around the edges to prevent the fire from jumping
into the woods.
The City should also hire a prairie restoration firm to assist
in restoration of prairie grasses and forbes within the
savannah areas.
In the fall cut and remove undergrowth (usually
Buckthorn). Paint the herbicide Garlon on cut surfaces of
stems. The next spring, bum. Because of lack of fuel it
may take a few years to get a complete bum. Savannah -
type grasses and forbes should start to reappear.
After an area is burned, seed in handfuls of grasses and
forbes (seeds and berries) appropriate to an oak savannah.
The prairie restoration firm can provide some of these
species. Others may have to be collected by volunteers
from local areas.
Initially a restored savannah should be burned every years.
Once the understory of desired species is established, the
burning can be done every three to five years and
eventually once every ten to fifteen years.
Oak Woodland (Method A or WO -A-#)
This restoration method is for degraded woods (see Figure
& Site Analysis) with a sparse canopy or isolated mature
trees @ 150-200+ . feet apart. The understory is a
impenetrable wall of Buckthorn. These woodland areas
will be the most costly and exasperating to restore. This
method of management is geared towards eliminating the
dense understory of Buckthorn and replacing it with more
desirable species. This is a multiyear process because
Buckthorn is a prolific seeder.
Year One: In the fall or winter, cut and remove adult
Buckthorn (any stem over ; inch in diameter if possible).
Treat the cut stems with Garlon. This phase will eliminate
90-95% of the Buckthorn biomass. It is extremely labor
intensive (Rosemount may want to organize volunteer help.
A person licensed to apply herbicides must be in charge of
Carrolls Woods Nature Area
training and overseeing the volunteer help.)
Year Two: Plant 75 saplings per acre. Plant Red Oak,
White Oak, Black Cherry, and Green Ash. Use the Tubex
5' tree shelters for these saplings. These tubes will serve
3 functions:
• protect the saplings from rodents and deer
• create condensation which will help the saplings survive
the drought -prone soils.
• protect the saplings from herbicide sprays.
After planting, use a foliar spray (such as Krenite or
Round -up) to kill off all the Buckthorn seedlings. These
sprays will kill any green growing plant that they contact.
Buckthorn remains green and growing in the forest 2-14
days after most native vegetation goes dormant in the
autumn. This time may be the best time to spray in order
to preserve as much non -Buckthorn understory vegetation
as possible. Rosemount will need expert advice from the
herbicide distributor as to timing of application (the
window of opportunity varies from year to year and can be
quite small).
Year Three: Apply a foliar spray again to eliminate any
remaining Buckthorn seedlings. Seed each acre with
acorns or plant oak/cherry seedlings (2000/acre). The
DNR sells 1000 tree seedlings for $150. Acorns are not
available commercially; collecting them could be a
volunteer effort in early to mid August. One drawback for
acorns is that not every year is a productive year for oaks
to produce them.
Subsequent years: Monitor the restored areas for
buckthorn regeneration. Continue to eliminate either by
cutting and applying Garlon to the cut stems or by using
foliar sprays for pockets of infestation.
Oak Woodland (Method B or WO -B-#)
This management method is for pleasant woods (see Figure
& Site Analysis) with a well-developed canopy of mature
trees and a moderate Buckthorn understory. Management
efforts should be directed at eliminating Buckthorn,
especially the mature individuals and ones in the occasional
openings in the canopy, and supplementing the planting
especially in openings.
Year One: Cut and remove adult Buckthorn (over � inch
in diameter). Apply Garlon to cut stems. Replace the
Buckthorn with tree saplings or shade -tolerant shrubs.
Possible species:
Common or Scarlet Elderberry (Sambucus eanadensis
or pubens)
City of Rosemount
American Hazelnut (Corylus americana)
Nannyberry (Viburnum lentago)
Gray Dogwood (Comus racemosa)
Pagoda Dogwood (Comus alternifolia)
Round -Leafed Dogwood (Cornus rugosa)
Serviceberry (Amelanchier canadensis)
Gooseberry (Ribes cynosbati)
Raspberry (Rubus strigosus)
Prickly Ash (Zanthoxylum americana)
Green Ash (Fraxinus pennsylvanica)
Red Oak (Quercus rubra)
Northern Pin Oak (Quercus ellipsoidalis)
White Oak (Quercus alba)
Black Cherry (Prunus serotina)
Hackberry (Celtis occidentalis)
If there are any large openings in these zones with solid
stands of Buckthorn, eliminate using Method A.
Year Two: Monitor these zones, cut and apply Garlon to
any remaining Buckthorn. Continue to add shrubs and
saplings if needed. Begin to enrich the herbaceous layer
in shady areas with appropriate wildflowers.
Oak Woodland (Method C)
This restoration method is for north -facing slopes with an
open canopy and a fairly dense understory of Buckthorn.
For areas without canopy trees and heavy Buckthorn, use
Method A. When planting, use the species listed below.
For areas with canopy trees and some Buckthorn, use
Method B.
Species to plant:
Sugar Maple (Acer saccharum)
Basswood (Tilia americana)
Ironwood (Ostrya virginiana)
Black Cherry (Prunus serotina)
Hackberry (Celtic occidentalis)
Red Oak (Quercus rubra)
Butternut (Juglans cinera)
Black Walnut (Juglans nigra)
As the Buckthorn is eliminated and the canopy begins to
fill in, enrich the forest floor with wildflowers called spring
ephemerals.
Lowland Woods (WL)
These small areas of the site are disturbed frequently by
groundwater or wet soil conditions. This community will
not require much management except to prevent
disturbance of the drainage systems and to eliminate
infestations of Buckthorn.
Successional Woods (WS)
Successional forest: these areas are dominated by
pioneering plants and have few mature trees and a dense
understory of a variety of species. The only management
needed for these areas is to control Buckthorn invasions.
Woodland Pothole
The area in the southwest comer of Carrolls Woods was
once quite productive waterfowl habitat. In the last twenty
years it has silted in and become dry enough for Silver
Maples to grow. To make the area a pothole again, it
must be dredged, regraded, and perhaps sealed to prevent
water from seeping away. If possible the City should
construct a small siltation pond to filter all stormwater
runoff before it enters the pothole. Once open water is
provided, the bird (and animal) life will return.
Schwarz Pond
The fluctuations in water levels for this pond actually
increase its productivity as a food source for waterfowl.
Discontinuing mowing and planting prairie would improve
this area as habitat for birds and animals. Some wildlife
plantings along the fence will help screen it. The City or
school should monitor water quality in future years.
Wildlife Habitat Program
One of the primary objectives for this park is to establish
diverse wildlife habitat which provides food, water, and
shelter for a variety of wildlife species.
Although the pallet of plants included in the Vegetation
Management Program for the park will provide habitat for
several wildlife species, a wildlife management program
will add extra components to improve the diversity of
species using the nature area.
A number of state and regional resources are available to
help develop a wildlife habitat and management program.
The Minnesota Department of Natural Resources (D.N.R.)
have individuals with expertise necessary to:
• evaluate existing habitat and its potential to support
wildlife.
Carrolls Woods Nature Area City of Rosemount
am
• recommend habitat development programs to improve
the habitat that is already present.
• identify the bearing capacity of the park and ways to
maintain a healthy wildlife population.
The City should contact the D.N.R. Section of Wildlife
prior to future development to insure that no opportunities
are missed along the way.
Based on the DN.R: s guidelines, fifteen components of
wildlife habitat are necessary to fulfill the major needs of
most species. Eight of these components are plants and
eight are structural or non -living components.
Plant Components:
• grasses/legumes
• butterfly, bees, moth plants
• hummingbird plants
• summer plants
• fall plants
• winter plants
• nut/acorn trees
Structural Components:
• feeders
• water
• dust beds/grit
• salt
• cut banks/cliffs/banks
• brush/rock piles
snags
• nest boxes
By providing these components, the community will
improve the chances of wildlife flourishing within the
confines of this nature area.
Cost Estimate and General
Phasing Program
Although certainly not an exact science, estimating or
projecting the costs to develop this park is important
because it provides the citizens of the community,
governing bodies, and City staff with a basic understanding
of the economic commitment necessary to put the park's
Master Plan into effect. The estimated costs to develop
the park will affect priorities for adding the various
components and amenities and in deciding which ones are
best accomplished through volunteer efforts versus paid
contracts.
The City and Advisory Committee should use the figures
below only as "benchmarks" to compare the relative costs
of items and for budgeting purposes. Actual cost to
acquire land and develop the Master Plan will depend a
great deal on:
• the actual land values at the time of acquisition.
the actual construction costs at the time of
development.
• how much of the costs for development can be offset
through alternative funding programs, such as
volunteerism, grants, donations, etc.
The cost estimates below are based on estimated land
values in 1991 dollars (determined by the City) and typical
development costs in 1991 dollars (as determined by
industry cost -to -construct averages, i.e. what it would
typically cost, on average, for a contractor to come in and
do the work).
Park Land Acquisition Costs
The Master Plan includes two parcels of land which the
City does not currently own.
The first parcel (Parcel C) has the highest priority for
acquisition because it plays an critical role in the long term
objectives of the Master Plan. Based on current land prices
in the City of $8,000 to $11,000 per acre, the cost for the
15 acres identified in the master plan would range from
$120,000 to $165,000.
The second parcel (Parcel D) plays an important secondary
role in the long term objectives of the Master Plan. It
provides an area for support facilities (e.g., parking lot)
and neighborhood recreational facilities. Again based on
current land prices in the City of $8,000 to $11,000 per
acre, the cost for the 7 acres identified in the master plan
would range from $56,000 to $77,000.
Although these two parcels play an important role in the
park's Master Plan, they may not be either available for
purchase or the City may not be able to fund their
acquisition. If this becomes the case, the overall integrity
of the Master Plan is not lost. Even without these parcels,
the park will be a priceless natural resource and will make
a significant contribution to the park system within the
community. However, if the vision of this master planning
process is to be realized, every effort should be made to
include these parcels within the park.
Carrolls Woods Nature Area City of Rosemount
,L
Park Development Costs
The cost estimate and general phasing program for
developing the park is illustrated in Figure 13 Cost
Estimate and General Phasing Program.
The suggested phasing is based on the most reasonable
approach to the park's future development. The vegetative
management programs are the top priorities. The auxiliary
site amenities can be added in the future. The phasing
program is based on the best judgements given current
conditions. Since conditions and opportunities often
change over time, the City and Advisory Committee should
review the phasing program on a periodic basis to change
priorities if necessary.
Interpretive/Education Programs
One of the important program elements for this park is the
an interpretive and environmental education program to
emphasize the importance of preservation and conservation
of limited natural resources.
The programs should focus on native plant communities,
how they evolve and maintain themselves, and on the
wildlife which depend on them for survival. These
programs should also emphasize the use of native plants
around homes and the benefits they provide, both in an
aesthetic and practical sense (such as wind screening,
shade, attraction to wildlife, etc.).
Environmental education programs for elementary and
secondary schools should be a high priority, considering the
park's proximity to the nearby schools.
The Minnesota Department of Education often assists
communities in developing environmental educational
programs. State personnel, along with local school district
staff, should be contacted and asked to help create these
programs.
Interpretive programs should be created to reach a wide
variety of people and age groups. Interpretive programs
typically focus on providing park visitors with information
about the plant communities and wildlife within the park.
These programs often include:
• interpretive nodes (low profile kiosks with interpretive
panels).
• interpretive signs throughout the park which describes
different features.
maps and handouts with text describing the park's
ecological systems, wildlife, geology, etc.
Development of interpretive programs should also include
the Minnesota Department of Education, local school
district staff, as well as a naturalist and other
environmental professionals.
Existing Community Programs
This Master Plan does not intend to exclude existing and
successful community programs from taking place within
park boundaries. However these programs should occur
only if they do not cause any negative impacts on the
park's natural character. Organized events bring visitors to
the park and create experiences which give people a vested
interest in the future of the park. A pleasant memory of
a place can motivate people to protect it as a resource.
As an example, there is no compelling reason why the
Haunted Woods program should not continue as it. has in
the past as long as its organizers take reasonable care to
protect fragile plant life from damage. To accomplish this,
organizers of community programs should work closely
with the Advisory Committee in selecting a route and
location for props. In the future, when the nature area is
fully restored and developed, the Haunted Woods program
may be better suited to another location. The organizers
should work with the Parks and Recreation Committee and
city staff in the next few years to see if another more
suitable site exists. In the interim, the Haunted Woods
program should continue.
Advisory Committee
The City should establish an advisory committee to oversee
and guide the future development and protection of
Carrolls Woods Nature Area. The Committee should be
made up of individuals with different backgrounds who can
help give direction and motivation to the community in
support of the park's Master Plan. The Advisory
Committee should work directly with the Parks &
Recreation Committee and City staff to guarantee that the
park's best interests are served.
The City Council should formally accept the Advisory
Committee in ,an advisory role and as the guiding force
behind the park's future development in order to add
strength to Advisory Committee's position.
Carrolls Woods Nature Area City of Rosemount
The Committee's make-up should include:
• local citizens who are concerned about the park's future
and want to contribute their energies toward insuring
that its mission is carried out.
• members of local conservation organizations with
interest and expertise in native habitat, wildlife
observation and wildflower gardening.
• members of local garden club(s) who have a special
interest in native plants and gardening.
• teachers in the local educational community who have
an interest in environmental education and
interpretation.
• community leaders who can provide political guidance
and potential sources of private funding.
• a City staff member(s) to assist in guiding the project
through administrative and political channels.
The Advisory Committee's involvement in the development
of the park should occur prior to the design development
stage of the project. The Advisory Committee should use
the Master Plan as a guide to any development within the
park. Other key responsibilities for the Committee
include:
• interpreting the master plan document, including
periodic review of the plan itself and the priorities for
phasing.
• implementing the plan, including scheduling of
improvements, securing professional assistance as
necessary, and making recommendations to the Parks
& Recreation Committee, City st4 and City Council.
• initiating education and interpretive programs.
• initiating public awareness programs and public meeting
to keep the citizens of Rosemount aware of the park's
development.
• initiating volunteer programs to assist in the
development of the park and reduce development costs.
• providing on-going guidance and support to volunteer
and educational programs to insure the long-term
success of the park.
• monitoring maintenance practices so that they stay
within the intent of the Master Plan.
monitoring existing community programs (such as the
Haunted Woods) and work with program organizers to
guarantee that the best interests of the park are served.

Conclusion
The citizens of Rosemount should commend its City
Council, Park and Recreation Committee, and the Advisory
Committee for their concern in planning for such a
valuable community resource as the Carrolls Woods
Nature Area. The Advisory Committee especially put in
many hours debating the issues facing this park and came
to some tough and critical decisions about its future.
Carrolls Woods Nature Area is a treasure for future
generations. Rosemount is lucky to have several citizens
who feel passionate about its existence and the quality of
its environment. Their energy can motivate the community
and create the support necessary to implement the Master
Plan.
