North Star Nature Preserve Management Plan 3
SECTION I
Land Ethic
The land ethic simply enlarges the boundaries of the community to include soils, waters,plants,and
animals, or collectively:the land.
This sounds simple:do we not already sing our love for and obligation to the land of the free and the
home of the brave?Yes, but just what and whom do we love?Certaialynot the soil, which we are sending
helter-skelter downriver. Certainly not the waters, which we assume have no function except to turn turbines,
Boat barges, and carry off sewage. Certamlynot theplants, of which we exterminate whole communities
without batting an eye. Certainly not the animals, of which we have already extirpated many of the largest and
most beautiful species.Aland ethic of course cannot prevent the aheration management, and use of these
`resources,'but it does aAum their right to continued existence, and, at least in spots, their continued
existence in a natural state. Leopold,Aldo:A Sand County Almanac,and Sketches Here and There,1948,

1.01 FOREWORD
The North Star Nature Preserve is a unique and valuable tract of open space in Pitkin County
where development and recreation pressures threaten the integrity of the natural environment.
Although the original intent for the acquisition of North Star was for both passive recreation and
wildlife habitat protection[, public lands available for recreation are quite abundant in the
Roaring Fork Valley whereas elk migration corridors and other critical wildlife habitats protected
at North Star are being lost at an unprecedented rate.
This plan is the product of many BOCC meetings and the undaunted efforts of the North Star
Users Group who worked diligently over the 6 months preceding the adoption of this plan.
Although the members of the Users Group came into the User Group meetings with a variety of
opinions and special interests, we found that there were far more topics of agreement than
dissent.
The intent of this plan is to provide a basis for the long term management of the North Star
Nature Preserve that balances protection of the ecosystem processes that support the biological
diversity within the Preserve with compatible recreational and educational uses.
1.01.01 Background
In 1966, the Aspen Area General Plan was adopted allowing construction of up to 1500
houses on the North Star Ranch plus some recreational and commercial development..
Development of this magnitude was rejected by the landowner, James Smith, who, in 1973,
submitted an application for a 350 residence PUD. This application was denied by the Pitkin
County BOCC in its initial form and had not been resubmitted when, in 1974, a general County
rezoning took place. Consequently, North Star Ranch was rezoned to AF-1 reducing the
development potential of the property to 36 units. The primary intent and effect of AF
(Agriculture-Forestry) zoning was to reduce building potential to maintain the County's rural
The Pitkin County BOCC Resolution(77-105)exempting North Star Ranch from subdivision, ...the Board, ...has
determined that(a)the parcel to be conveyed will be devoted to trail, fishing,picnicking, kayak and like recreation
uses as well as wildlife preservation..."
North Star Nature Preserve Management Plan 2
atmosphere. This led to conversations between Mr. Smith and members of the Pitkin County
Parks Association (PCPA) concerning the possibility of converting part of the Ranch to Open
Space. Negotiations with the PCPA and the Aspen-Pitkin Planning Department led to the
selection of a 175 acre parcel within the Ranch and an appraisal of that parcel in 1977. The
Planning Department then took the lead in the acquisition process with the application of a
50/50 matching grant of $575,000 from the Federal Land and Water Conservation Fund,
administered through the Colorado Division of Parks and Recreation for the Federal Bureau of
Outdoor Recreation. When it was learned that this money would not be available in 1977, The
Nature Conservancy (TNC) was contacted.
TNC was familiar with the property and was anxious to assist in the County's acquisition.
Jon Mulford, TNC's local representative, renegotiated the purchase price to include a gift valued
at $275,000 from three generations of the Smith family. In November 1977, TNC took title to
175 acres of the North Star Ranch. In December 1978, Pitkin County took title from TNC. In
the meantime, a firm promise of Land and Water Conservation funds was made, but the amount
had shrunk to $75,000 leaving the County with the major funding burden, to be born primarily
by Payment-in-Lieu-of-Taxes (PILT) monies from the Federal Government. While this brief
outline of the acquisition process only touches on a complex series of negotiations, it does serve
to illustrate the many pressures and priorities that have been brought to bear on the property. In
addition, some consistent concepts were emphasized in most of the communiques between the
participating parties. Letters from Jon Mulford, attorney representing TNC, Bill Kane,
Aspen/Pitkin Planning Director, Sydney Macy, TNC Colorado Field Office Director, and James
Smith, Owner of The North Star Ranch, emphasized that the driving force behind the transfer of
North Star from private to public ownership was the protection of wildlife habitat and open
space. In a letter to the Pitkin County Planning and Zoning Commission dated July 18, 1984,
Sydney Macy wrote,
"The intent of the acquisition, which is in keeping with The Nature Conservancy's objective of
preserving natural areas, was that North Star Ranch be managed as a natural area for scientific
and educational purposes, while still encouraging and allowing some passive recreation".
Bill Kane, in a letter to Colorado Division of Parks and Outdoor Recreation, wrote, "It is our
contention that this land, if acquired, would present the prospect of an elk refuge in perpetuity".
Additionally, recent correspondence from Morgan Smith, son of James Smith, states that,
"...this donation[the$275,000 Smith family donation]...was intended to keep the land in
open space and for the purposes of wildlife. Whether this is reflected in whatever
documents may exist from the time of the donation, we never would have made the
donation if there had been discussion of commercial usages[sic]. In addition, it was
always our hope that this donation might serve as an example to others who are
interested in preserving land and protecting wildlife."
The North Star Nature Preserve is currently designated as Pitkin County Open Space. As
such, all rules and regulations specified in Pitkin County Resolution 25-93 apply to North Star.
Currently, North Star is being considered by the BOCC for inclusion into the Pitkin County
Open Space and Trails Program.
The information herein is largely based on the Design Workshop produced North Star Nature
Preserve Resource Management Plan, 1989 which in turn was a compilation of previous studies
and plans which included: Pitkin County BOCC Resolutions 77-98 and 77-105, 1977;
North Star Nature Preserve Management Plan 3
5
Environmental Assessment for North Star Ranch Open Space Acquisition Application, 1977;
North Star Nature Preserve Master Plan Draft, 1979; Vegetation Inventory, 1981; and The
Roaring Fork East Neighborhood Master Plan, 1985. Ecological Monitoring of North Star has
been conducted constantly since 1995 by the Aspen Center for Environmental Studies (ACES)
North Star Committee and Roaring Fork Watershed Coalition in conjunction with Dr. John
Emerick, Colorado School of Mines. This monitoring was funded in large part by Pitkin County.
Resulting data provided a strong ecological basis for the strategies within this plan.
1.01.02 The Present
The foundation of this management plan is ecology and conservation biology. The
conservation imperative at North Star is to preserve a mosaic of high quality native ecological
communities that support a high level of biological diversity. The current composition of the
current vegetational mosaic at North Star was largely shaped by human intervention. Future
management will instead focus on passive actions that assist the natural ecosystem processes that
control the representation of different vegetational communities and hydrological regimes.
North Star Preserve is a unique 175 acre tract of open space land about 1 '/2 miles east of
Aspen, Colorado. The topography contrasts sharply with regional landforms as the Preserve is a
relatively flat bottomland surrounded by the steep mountain slopes of Richmond Hill/Bell
Mountain and Smuggler Mountain. The landform is a result of modification during periods of
glaciation of the Pleistocene Epoch. A terminal moraine at the north end of the North Star
Preserve created a glacial lake which filled with stream deposited materials, before the river
broke through the morainal dam. As a result, two soil types are present: Agrolls in the
bottomlands along the river, and an unnamed peaty loam on alluvial fans at the base of
Richmond Hill/Bell Mountain.
North Star's vegetation is influenced by the climate near Aspen which is continental in
character and subject to sudden extreme temperature changes. Only June through September are
warm enough to foster growth. The Preserve is usually snow covered from November through
March.
Until 30 years ago most of the Preserve was dominated by the willow riparian vegetational
community (or carr), and occasional islands of cottonwoods and blue spruce. Thereafter it was
managed as a ranch for hay and grazing and became pastoral in character. Presently, ten distinct
vegetational communities occur at North Star: mixed conifer forest, aspen forest, cottonwood
riparian, willow riparian, oak-serviceberry shrubland, dry meadow, mesic hayfields, wet
meadow, emergent sedge wetland, and open water (Hickey and Emerick 2000).
In 1977, the land was acquired by the Nature Conservancy and transferred to Pitkin County
in 1978. From 1984 until the Spring of 1999, North Star was managed by the Aspen Center for
Environmental Studies (ACES) and is now being managed by Pitkin County.
The North Star Nature Preserve is a valuable resource to Pitkin County and the City of Aspen
for many reasons, including:
as a sanctuary for wildlife
as a public amenity for quiet recreation, including fishing, canoeing, and nature
appreciation
North Star Nature Preserve Management Plan 4
l�
as a visual resource on a scenic highway entering Aspen
a vital area for clean air and water quality
as a living classroom for environmental education
as a deep underground aquifer, the North Star Nature Preserve sustains the health of the
Roaring Fork River
flood abatement in wet years and river recharge in dry years
Intensive economic pressure in and around Aspen has created a strong need to ensure that
North Star is maintained as a nature preserve in perpetuity. An additional 60 acres of land have
been acquired by ACES but is separated from North Star by private property. Both recreation
and residential development threaten the ecological integrity of the Nature Preserve.
The following recommendations have been developed in order to manage the Nature
Preserve as a nature sanctuary and public amenity, in the context of the Roaring Fork Valley.
1.02 CONCEPTS
The objectives for managing North Star have evolved through the aims of the Nature
Conservancy, the conditions of sale by James H. Smith, Pitkin County, Roaring Fork East
Neighborhood Master Plan, and Aspen Center for Environmental Studies. The foundation of this
management plan is ecology and conservation biology and the conservation imperative at North
Star is to preserve a mosaic of high quality native ecological communities that support a high
level of biological diversity. Although the composition of the current vegetational mosaic at
North Star was largely dictated by human intervention future management will focus on
management actions that assist the natural ecosystem processes that support the representation of
North Star's vegetational communities and hydrological regimes.
North Star provides tremendous benefits to both the ecology and the people of the upper Roaring
Fork Valley:
1.02.01 ECOLOGY
Ecological studies and inventories conducted at North Star have revealed that North Star
supports a high level of biological diversity: 17 species of small mammals (e.g., mice, voles,
shrews, squirrels); at least 107 species of birds, more than 60 of which are like to breed at North
Star (including 4 U.S. Forest Service Designated "Sensitive" species); 13 medium to large
mammals (e.g., elk, coyote, black bear, bobcat); 3 species of amphibian (including the boreal
toad which is a U.S. Fish and Wildlife Service Endangered Species Act "Candidate" species);
and one reptile species (common garter snake).
Included within the birds are at least 6 species that nest on the ground. These species are
especially sensitive to human recreational disturbance and will abandon a nest after repetitive
disturbance ((Tremblay and Ellison 1979); (Jeffrey 1987); (Yalden and Yalden 1990); (Hockin et
al. 1992); (Watson et al. 1996)). When flushed from a nest by human activity the young or eggs
are exposed to weather and are vulnerable to predators such as ravens, raccoons, and foxes. As
well, young birds require almost continuous feeding and may become weakened and die if the
adults are otherwise occupied. Even if humans are careful, it is easy to step on eggs or chicks.
The cryptic eggs of killdeers and vesper sparrows blend in with the surrounding ground or

vegetation. Killdeer nests are little more than a few sticks and stones and are very difficult to see.
Nesting ducks will stay away for as long as humans are in close proximity. This can lead to death
of the eggs due to excessive cooling or exposure to the sun. More frequently, it leads to nest
abandonment or destruction of the nest by magpies or other predators.
Of particular conservation interest at North Star is a Great Blue Heron colony. It is estimated
that there are only 63 Great Blue Heron colonies in the entire state of Colorado and the North
Star colony is thought to be one of just a few occurring over 8000 feet in elevation and is the
only one occurring in blue spruce trees (most occur in cottonwoods). In other words, the North
Star Great Blue Heron colony is quite unique and ecologically significant. The presence of this
colony has important management implications. Research has resulted in a recommend a
minimum 200 meter buffer zone from the periphery of colonies in which no human activity
should take place during courtship and nesting seasons ((Vos et al. 1985); (Miller et al. 1998);
(Carney and Sydeman 1999)). Because colonies may move every few years, management plans
should encompass entire river systems ((Parker 1980)).
If, and it appears likely, boreal toads are federally listed as "Endangered" or "Threatened",
then we will be bound by law to increase the protective status of North Star.
A. Other Key Ecological Concepts
(1) North Star is a vital link in the Roaring Fork Watershed ecosystem. Plans for the
preservation of the health of natural systems in North Star will not be effective unless they
are supported throughout the system.
(2) North Star represents a high quality remnant of minimally disturbed riparian/montane
wildlife habitat surrounded by human development that serves to connect landscape
elements required by many wildlife species for different life history stages.
a) Significant ecological aspects of North Star as part of a landscape mosaic:
The Roaring Fork River riparian community and floodplain
Elk migration corridor
Elk calving area
Migratory stop for:
neotropical song birds (e.g., Wilson's warbler, American pipit)
resident mammals that migrate elevationally (e.g., coyote, black bear, mule deer)
waterfowl (e.g., gadwall, ring-necked duck)
Breeding site for:
resident birds that migrate elevationally (e.g., fox sparrow, song sparrow)
neotropical migrant song birds, wading birds, and waterfowl (e.g., yellow
warbler, warbling vireo, spotted sandpiper, mallard)
medium to large mammals (e.g., coyote, black bear, red fox, short-tailed weasel,
American marten)
raptors (e.g., red-tailed hawk, northern goshawk)
great blue heron
Habitat and potential breeding habitat for State Endangered and Federal Category I
(warranted but precluded) Candidate endangered boreal toad (Bufo boreas boreas)
Spawning site for wild trout
North Star Nature Preserve Management Plan 6
Breeding habitat for approximately 14 species of small mammals (e.g., montane
shrew, meadow vole, brush mouse)
Supports 3 rare vegetational communities considered to be vulnerable through their
range or found locally in a restricted range ((Spackman et al. 1999)):
Water Sedge-Beaked Sedge (Carex aquatilis-Carex utriculata) montane sedge
wetland
Geyer's Willow-Montane Willow (Salix gereriana-Salix monticola) montane
willow carr
Drummond's Willow-Beaked Sedge (Salix drummondiana-Carex utriculata)
montane willow carr
1.02.02 PEOPLE
North Star provides many benefits to both visitors and residents of the Roaring Fork Valley
which include the following:
Chemical and physical filtering of surface runoff resulting in a cleaner, more productive
river for both wildlife and people
Opportunity for solitude immediately adjacent to population center
Opportunity to observe wildlife in natural setting immediately adjacent to population
center
Opportunity for quiet recreational activities (e.g., fishing, bird watching, kayaking,
meditation)
Opportunity to serve as living classroom for environmental education and research
1.03 ECOLOGICAL COMMUNITIES
1.03.01 The Roaring Fork River
The Roaring Fork River meanders through the meadows of North Star, constantly changing
and rejuvenating the ecological communities it has helped to create. The river here is a wide
valley bottom stream with a sand, gravel, and paleo-peat substrate. The river has meandered
back and forth across the valley floor over time creating a system of old river channels and
oxbow lakes that are at different stages of eutrophication (i.e., enrichment of water by nutrients
resulting in increased vegetational growth). This results in a productive complex of permanent
and ephemeral ponds, sedge and sedge-willow dominated marshes, and wet meadows.
Sedge and sedge-willow marsh occupies areas with a high water table totaling approximately
35 acres. A four acre area of wet meadow occurs in areas that flood only early in the growing
season. Together these wetlands play an important role in absorbing the impact of spring
flooding and help assure Roaring Fork River water quality by filtering out silt and contaminants.
The treatment of riparian habitats in the past and their current condition is alarming. For
example, it has been estimated that in the Rocky Mountain-Great Plains region, 90-95% of the
cottonwood-willow riparian ecological community have been lost to development and
agriculture. In the American West, these communities support a disproportionately greater
number of wildlife than their upland counterparts. In fact, although less than 1% of the land in
North Star Nature Preserve Management Plan 7
I
Colorado is riparian over 60% of the vertebrates are obligates to riparian ecosystems and
approximately 85% require riparian habitat for some aspect of their life history (Ohmart and
Anderson 1986).
Rainbow trout in the river at North Star are small and less abundant than in other parts of the
River, probably due to the granitic nature of the simple sandy river bottom and lack of coarse
woody debris for hiding and thermal cover. Other, smaller fish species also thrive in the spring
fed ponds but have yet to be identified. Beavers have built a bank lodge and runway on the west
side of the river towards the south end of North Star. Waterfowl and songbirds abound along the
river edges and in the sedge-willow marshes. The ephemeral ponds provide optimal habitat for
western chorus frogs that in turn are prey for great blue herons. The permanent oxbow and
spring-fed ponds provide both migratory and breeding habitat for various duck species as well as
Canada geese. The wet meadows are host to a plethora of small mammal species. American
dippers, spotted sandpipers, and muskrats all make the river and its shores their home.
Spring flood events have been restoring the meanders to the Roaring Fork River at North
Star. Alternating banks are either sites of erosion or deposition. This is a natural process and is
important to the ecology of a riverine system in that it creates a diversity of habitats and allows
the river to access its flood plain. The beaches that develop as a result of this activity are critical
to regeneration of willows and cottonwoods and are very sensitive to disturbance. People
walking, picnicking, or beaching canoes and kayaks trample seedlings and reduce cottonwood,
willow, and sedge regeneration. Anglers also have a direct negative impact by denuding
vegetation along the river's edge, causing banks to slough into the river, and increasing erosion.
Consequently, it is important that visitors are made aware of these impacts and encouraged to
tread lightly.
Another issue of concern is that releases from Grizzly Reservoir at the headwaters of Lincoln
Creek are too late in the season and not gradual enough resulting in erosion processes that are
damaging the morphology and ecology of the upper and middle Roaring Fork including North
Star.
The river is a major attraction to people. As it flows through the Nature Preserve, it offers a
quiet meditative place, a couple of sandy beaches, limited canoeing and kayaking, catch and
release fishing, and nature viewing and education.
A. Management Actions
(1) The river will be managed to maintain semi-natural flood regimes and promote wildlife
habitat. Periodic flooding of the Roaring Fork River is perhaps the most important
ecological process in restoring North Star to its pre-agricultural condition. Bank stabilization
will NOT be a management objective for the Roaring Fork within North Star. Rather, the
intention is to promote river processes that result in meanders, oxbows, and a functional
floodplain.
a) Various willow species, thinleaf alder, river birch, and narrowleaf cottonwoods will be
planted along the river and in the wet meadows to increase structural diversity of riparian
habitat
(i) This will be accomplished using both native plant materials collected on site and
purchased native plant materials
North Star Nature Preserve Management Plan 8
M -
(ii) Planted native vegetation will serve as natural barriers to prevent abuse of sensitive
habitat areas
(iii)Woody materials may be added to the river to increase fish habitat complexity
(a) Colorado Division of Wildlife fishery biologists will be consulted
(iv)Installation of drop structures will be considered as a means of raising the water table
to support the hydrological function of the wetlands
(2) Research the effects of the releases from Grizzly Reservoir on the fluvial geomorphology of
the Roaring Fork River at North Star
(3) Boardwalks will be considered at the north and south ends of the preserve (the put-in and
take-out) as a means of minimizing impacts
(4) The area surrounding the active beaver run and lodge will be off limits to the public
1.03.02 Dry Meadows
Dry meadows are the most extensive vegetation type at North Star. These meadows cover
approximately 100 acres and are largely the product of extensive draining, chaining, seeding,
burning, and other human manipulation for the purpose of agriculture. Originally, most of North
Star was covered by a dense willow Carr with occasional solitary narrowleaf cottonwoods
(Populus angustifolia) and Colorado blue spruce (Picea pungens) or clumps of these trees in the
drier sites. Beginning in the early 1950's, the landowner, James Hopkins Smith, Jr., adopted a
strategy of willow eradication. He cleared the site of the native vegetation and replaced it with
hay grasses, and either hayed or grazed it continually until the early 1980's.
The dry meadows are currently dominated by non-native grasses (e.g., smooth brome
[Bromopsis inermis], Common timothy [Phleum pratense], Orchardgrass [Dactylis glomerata]),
and a couple of native grasses (e.g., Aggassiz bluegrass [Poa agassizensis]). Noxious weeds
such as Canada thistle, plumeless thistle, houndstongue, oxeye daisy, tansy, and yellow toadflax
(AKA butter and eggs) are a significant problem in the dry meadows and threaten the ecological
integrity of this community.
Until 1978, North Star has been utilized for hay production and livestock grazing. The open
space character of the meadow is recognized as a strong feature of the preserve, yet the pastoral
character should be allowed to revert toward a more natural state.
Elk, mule deer, coyotes, fox, and red-tailed hawks all depend upon dry meadow along with
various small mammals and ground-nesting songbirds.
A. Management Actions
(1) Weed management
a) Noxious weeds will be managed via:
(i) Volunteer pulls
(ii) Spraying of approved herbicides by county staff
b) Overseeding the pasture with native grasses will be considered based on cost
c) Prescribed burning is considered too great a risk in this location

(2) Improve wildlife habitat and encourage natural succession in the dry meadows
a) Selected areas will be planted with willow and native shrubs to increase habitat
complexity and forage for mule deer and elk
b) Natural succession back to a willow carr will be facilitated by filling drainage ditches and
removing culverts
c) Natural narrowleaf cottonwood regeneration will be facilitated by protecting suckers
from mule deer, elk, and beaver browsing. This will increase cover for larger wildlife
species and roosts for raptors and great blue herons
1.03.03 Sedge And Sedge-Willow Marshes
Marshes, the dynamic meeting places of land and water, are among the most productive
and diverse of all wildlife habitats. Not only do they attract a tremendous diversity of life, but
they perform numerous functions that benefit humans as well. Since the dawn of human
civilization people have been drawn to wetlands because of the goods (rich agricultural soil,
timber for fuel and construction, fish, drinking water) and services (transport, water storage,
storm protection, shoreline stabilization, erosion control, water purification, retention of
pollutants, recreation) which they have to offer. Wetlands have been described as "the kidneys
of the landscape"because of their water purifying roles and "biological supermarkets" because
of their natural resources which humans exploit. Human dependence on water is absolute (as is
all life) and, therefore, by extension, so is our dependence on wetlands. The valuable functions
performed by marshes and other wetlands include:
Conveyance and storage of floodwaters Erosion prevention
Sediment control Wildlife habitat
Recreation Water supply and quality maintenance
Educational value Open space and aesthetic value
The marshes at North Star occupy approximately 35 acres and are dominated by beaked
sedge (Carex utriculata) and five willow species: whiplash willow (Salix lasiandra), Bebb's
willow (S. bebbiana), Drummond's willow (S. drummondiana), Geyer's willow (S. geyeriana),
and Rocky Mountain willow (S. monticola). Beaked sedge covers approximately 80% of all the
marshes occurring at North Star with fowl bluegrass (Poa palustris) and other native graminoids
occupying the rest. A major problem in the marshes and wet meadows is the encroachment of
reed canarygrass (Phalaris arundinacea) into the wetlands. Because reed canarygrass is highly
competitive, it poses a major threat to native wetland vegetation. Currently, North Star is
developing acres of dense monocultures of reed canarygrass, resulting in the loss of dynamic
physical and abiotic features and, in turn, decreased diversity of plants and animals. Reed
canarygrass has little to no forage value to wildlife.
Native wildlife depending on the marshes at North Star include:
Boreal toad Western chorus frog Rainbow trout
Yellow warbler Cedar waxwing Red-winged blackbird
Sora Virginia rail Great blue heron
Mink Beaver Muskrat
Long-tailed weasel Water shrew Masked shrew
Merriam's shrew Western jumping mouse Eared grebe

A. Management Actions
1) As mentioned earlier, the sedge and sedge-willow marshes will, for the most part, be
passively encouraged to expand.
a) All drainage ditches on North Star will be filled or redirected so as to restore the
hydrology originating on the slopes above the property and the springs at the toe of
those slopes
b) The culverts draining the west side of North Star will be removed and replaced with a
headgate that will facilitate both mosquito control and restoration of the hydrology
i) The mosquito control district (Bob Oxenburg) has offered to pay for this
headgate)
c) Willows (Salix spp.), thinleaf alder (Alnus incana), and river birch (Betula
occidentalis) will be planted in a few places along the edges of sedge dominated
marshes on the west side of the river
d) Willow cuttings and wattles will be planted along the river as well as the ephemeral
and permanent streams on the east side of the river that flow under Colorado State
Highway 82
e) All new plantings will be protected with welded wire for two growing seasons to
protect from elk, mule deer, and beaver foraging
2) The marshes will be a primary focus of interpretive signage and environmental education
efforts
a) All interpretive signage and displays will be placed along the East of Aspen Trail
bordering North Star
b) All regulatory signage will be placed along the East of Aspen Trail bordering North
Star
3) Users will be advised (via signage) to stay on existing trails
a) If it becomes necessary due to increasing user impacts, interpretive boardwalks will
be constructed in the access corridors to control impacts
(i) Since these boardwalks may cross marshes every precaution will be taken to
avoid any significant impact
4) Intensive management of reed canarygrass will be considered via:
a) Herbicides (e.g., Rodeo)
b) over-planting/over-seeding
c) mowing
d) integrated pest management methods (as per Kilbride and Paveglio 1999).
5) The existing gate in the northwest boundary (along the old Ute Trail) will be fixed and
locked
6) Signage will be placed along the northern boundary of the nature preserve to prevent
residents of the Preserve Subdivision and others from using the old Ute Trail or
trespassing in the Sanctuary portion of North Star
a) Interpretive signage will be placed along this boundary explaining the prohibition

1.03.04 Alluvial Fans,Aspen Groves, and Oak-Serviceberry Shrublands
Two aspen forest stands occur on alluvial fans at the base of Bell Mountain. At higher
elevations aspen forests give way to Gambel oak shrubland which extends up the slopes of the
mountain mixed with Douglas fir and lodgepole pine. On the meadow side, rabbit brush
shrubland forms an edge between the heights of the forest and the flatness of the meadow.
The aspen stands and rabbit brush Shrublands cover approximately 26 acres. These
vegetational communities are considered seral, owing their presence to disturbance (e.g., fire,
avalanche). Site conditions at North Star may be such that they will persist over time.
Disturbances in the fans (e.g., avalanche or water depositions of colluvium) may maintain
colonizing aspen stands, and the dryness of the rabbitbrush shrubland area will discourage
domination of aspen. Due to the nature of alluvial fans, and the activity of pocket gophers, the
soils in and around the fans are constantly disturbed. Consequently, noxious weeds are present
and pose a threat to the integrity of this community.
According to Roger Hollowell, former Ranch Manager of the North Star Ranch, as many as
50 elk cows formerly calved in the aspen on the alluvial fans. Currently, only a handful are
doing so. Although it is difficult to determine the cause of this decline, it is likely that human
activity has contributed. A diverse array of other wildlife depends on the alluvial fan ecological
community for daily or seasonal life history requirements such as:
. Northern goshawk . Red-tailed hawk . Great horned owl
. Meadow vole . Deer mouse . Pocket gopher
. Black bear . Mule deer . Red fox
. Coyote . Warbling vireo . Western wood pewee
. Red-naped sapsucker . Yellow rumped warbler . Magillivray's warbler
The montane Shrublands at the North Star Nature Preserve are relatively dry areas on upland
sites on the slopes of Richmond Hill. They are characterized by dense stands of Gambel oak,
Saskatoon serviceberry, snowberry, Wood's rose, and chokecherry with an occasional aspen,
Douglas fir, or ponderosa pine. The montane shrub vegetational community provides an
abundant food source and protected nest sites for a plethora of birds and mammals. Spotted
towhees sing from the shrubs and Virginia's warblers build nests in the dense shrubs which
protect their eggs and nestling from predators. Least chipmunks, golden-mantled ground
squirrels, and snowshoe hares abound. North Star's shrublands also provide habitat for various
shrews, voles, mice, bats, snowshoe hare, coyotes, black bears, and mountain lions.
A. Management Actions
(1) Management will be limited to noxious weed control via:
a) volunteer pulls
b) backpack and ATV spraying of approved herbicides by county staff
c) biological control
(2) If, over time, it appears that the aspen stands are being replaced by conifers due to a lack of
disturbance, aspen regeneration can be encouraged via selective cutting
(3) Interpretive displays will be placed along the East of Aspen Trail to explain the ecology of
these communities
North Star Nature Preserve Management Plan 12
1.03.05 Mixed Conifer Forest
Douglas fir that is mixed with Engelmann spruce, lodgepole pine, and aspen dominates the
forested areas on the slopes of Richmond Hill. Mountain maple is a common understory species
in the denser areas. In these undisturbed forests, species that require interior forest habitat thrive.
Sensitive mature forest interior residents such as American martens, three-toed woodpeckers,
olive-sided flycatchers, and southern red-backed voles all live on these slopes. Two raptor
species that require this type of habitat, northern goshawks and boreal owls, both nest and hunt
on the slopes of Richmond Hill within North Star.
These coniferous forests are extremely important as snow collection areas. The greatest
effective precipitation in the region occurs in these forests. Water is stored in the soils and
slowly moves down the slopes to recharge the groundwater and resupply the wetlands and the
river in the valley below.
A diverse array of wildlife depends on the conifer forest ecological community for daily or
seasonal life history requirements such as:
Northern goshawk Pine grosbeak Ruby-crowned kinglet
Sourthern red-backed vole Boreal owl Pine marten
Black bear Pine squirrel Elk
Masked shrew Hermit thrush Snowshoe hare
A. Management Actions
(1) Management of these areas must be coordinated with the White River National Forest
and the special interest groups participating in the Richmond Ridge Master Plan process
(2) Interpretive displays will be placed along the East of Aspen Trail to explain the ecology
of these communities
1.04 WILDLIFE
1.04.01 Mule Deer& Elk
Currently, the Roaring Fork Watershed is experiencing an onslaught of unprecedented
development. Consequently, we are losing wildlife habitat at an alarming rate. Two of the more
charismatic wildlife species experiencing population declines because of this habitat conversion
in the Roaring Fork Valley are mule deer (Odecoileus hemionus) and Rocky Mountain elk
(Cervus elaphus nelsoni). Historically the valley floor and lower slopes of the Valley provided
habitat for deer and elk winter range, reproduction, and migration. Over the last 30 years,
however, human development and activity has destroyed much of the winter range and
calving/fawning habitat and blocked migration routes.
Mule deer are of particular concern as their numbers have dropped dramatically statewide
over the last few years. Resident deer use North Star in Spring, Summer, and Fall and migrate to
lower elevations in the winter. Fawning does occur at North Star and has increased over the last
few years as the shrublands have expanded, providing greater cover for does and fawns. Deer
would greatly benefit from an increase in shrub biomass and forb production.
North Star Nature Preserve Management Plan 13
l�
Presently a herd of approximately 50-100 elk use North Star as a migration corridor both in
spring (primarily April 15'h to May 151h) and fall primarily (October 15'h to November 15'h). In
addition, there is some history of calving in the aspen of the colluvial fans (May 15'h to June
15'h), but this is rare. As stated in the previous section as many as 50 elk cows calved in the
aspen on the alluvial fans. Currently, only a handful are doing so. Although it is difficult to
determine the cause of this decline, it is likely that human activity has contributed.
1.04.02 Other Large Mammals
Coyote (Canis latrans), fox (Vulpes velox), black bear (Ursus americana), badger (Taxidea
taxus), ermine (Mustela erminea), bobcat (Lynx rufus), American marten (Martes americana),
and beaver (Castor canadensis) all occur at North Star. Of special interest is the beaver since
they are keystone species, meaning that they create habitat for other wildlife species. There is a
historic beaver lodge on the south side of North Star. A new bank lodge was constructed in 1999
on the east side of the river toward the south end of the preserve and is currently active.
1.04.03 Birds
Over 100 species of birds have been identified at North Star. These birds consist of
residents, breeding neo-tropical migrants, and neo-tropical migrants that use North Star as a
stopover. The interspersion of aspen, willow riparian, and spring-fed ponds provide nesting and
foraging habitat for varied avian guilds. These guilds include woodpeckers and other cavity
nesters, non-cavity tree nesting songbirds, shrub nesting songbirds, ground nesting songbirds,
tree nesting wading birds, ground nesting wading birds, ground nesting waterfowl, nest-building
raptors, and cavity nesting raptors. The aspen and willows support rich insect life and offer
diverse nesting sites for perching birds. Waterfowl nest near the river but away from seasonally
flooding areas. Their chicks are led to these areas of forage and cover. The oxbow lakes, spring-
fed ponds, and quiet river waters are excellent duck habitat which is relatively scarce in the
Roaring Fork River.
Ground nesting species are especially sensitive to human recreational disturbance and will
abandon a nest after repetitive disturbance ((Tremblay and Ellison 1979); (Jeffrey 1987);
(Yalden and Yalden 1990); (Hockin et al. 1992); [Watson, 1996 #7). When flushed from a nest
by human activity the young or eggs are exposed to weather and are vulnerable to predators such
as ravens, raccoons, and foxes. As well, young birds require almost continuous feeding and may
become weakened and die if the adults are otherwise occupied. Even if humans are careful, it is
easy to step on eggs or chicks. The cryptic eggs of killdeers and green-tailed towhees blend in
with the surrounding ground or vegetation. Killdeer nests are little more than a few sticks and
stones and are very difficult to see. Nesting ducks will stay away for as long as humans are in
close proximity. This can lead to death of the eggs due to excessive cooling or exposure to the
sun. More frequently, it leads to nest abandonment or destruction of the nest by magpies or other
predators.
Of particular conservation interest is the Great Blue Heron colony on Joy Smith's property
but within 100 meters of North Star. It is estimated that there are approximately 63 Great Blue
Heron colonies in the entire state of Colorado and the Smith colony is thought to be the only one
occurring over 8500 feet in elevation and in blue spruce trees (most occur in cottonwoods). In
other words Great Blue Heron colony is quite unique and ecologically significant. The presence
of this colony has important management implications. In addition, most studies recommend a
North Star Nature Preserve Management Plan 14
minimum 200 meter buffer zone from the periphery of colonies in which no human activity
should take place during courtship and nesting seasons ((Vos et al. 1985); (Miller et al. 1998))
Because colonies may move every few years, management plans should encompass entire river
systems ((Parker 1980)).
1.04.04 Small Mammals
At least 13 species of small mammal (e.g., mice, shrews, voles, chipmunks, etc.) occur in the
various ecological communities at North Star. Among these species, some, such as the water
shrew (Sorex palustris) and masked shrew (Soren cinereus) are excellent indicators of high
quality wetlands and riparian areas. Monitoring small mammals can provide insight into
ecological change and human impacts since they have very small home ranges and do not
migrate. Consequently, even very small changes in environmental quality, vegetation,
hydrology, and/or soil compaction can be detected via shifts in small mammal species
composition and/or abundance.
A. Management Actions
(1) Encourage mule deer use of North Star by planting shrubs for forage and cover
(2) Plant willows and other native riparian shrubs for increased bird and waterfowl habitat
(3) Protect willow and cottonwood suckers against elk, mule deer, and beavers to improve
habitat structural heterogeneity
(4) Continue to restore the native willow carr to reestablish the original floral and faunal
species assemblages
1.05 RESEARCH& MONITORING
Research and monitoring of North Star is necessary to guide management. Currently,
volunteers led by the Watershed Coalition with financial and in-kind assistance from Pitkin
County, City of Aspen, and private sources are conducting vegetation, small mammal, and bird
monitoring that began in 1996. This work has produced invaluable information regarding the
species composition and population trends within each of the ecological communities that
comprise North Star. The monitoring project is being conducted in concert with a larger project
directed by a research team from the Environmental Science and Engineering Division, Colorado
School of Mines (CSM). The goal of the greater project is to examine the ecological and
hydrological processes of the upper Roaring Fork Watershed using a watershed modeling.
Upon completion of the CSM project, the vegetation, bird, and small mammal monitoring
will continue ad infinatum. In addition, a GPS/GIS monitoring program was begun in 1999 to
evaluate the size and proportion of each vegetational community at North Star with a special
emphasis on the wetland, riparian, and open water communities. Noxious weed infestations will
be tracked over time using the same methods. Two permanent vegetation plots will be randomly
placed in each of North Star's vegetational communities to track changes over time. This
program will also be continuous.
North Star Nature Preserve Management Plan 15
1.06 PEOPLE & RECREATION
Recreational pressures on public lands in Colorado and the Roaring Fork Valley are increasing as
our human population continues to grow. Current recreational uses at North Star include:
t Wildlife and nature observation
�h Environmental education
Vh Wildlife and scenic photography
% Canoeing, kayaking, and rafting
0 Paragliding and Hang gliding
Ah Catch and release fly-fishing
These recreational pressures affect wildlife and plant species diversity, survivorship, and
recruitment. In addition, some of these activities cause erosion and soil compaction. Although
North Star is ecologically sensitive and any human use will have an impact, it is also an
important cultural asset to the citizens of the Roaring Fork Valley that can further ecological
awareness and understanding. As such, one of the most important goals of this plan is to
achieve a balance between North Star as a nature preserve and as a cultural resource.

1.07 NEIGHBORS/SURROUNDING LAND USES
North Star Nature Preserve is the perfect neighbor to a homeowner. It is a quiet place
which offers beautiful vistas and the opportunity to observe wildlife, while affording a sense of
both space and privacy to adjacent properties. In order to maintain this landscape, it is important
that adjacent property owners respect the same guidelines used at North Star.
A. Management Actions
(1) North Star's neighbors should be encouraged to:
a) Respect the following conservation guidelines:
(i) Do not build in the floodplain
(ii) Protect wetlands on private land
(iii) Preserve the riparian zone and river
(iv) Preserve existing natural vegetation
(v) Manage noxious weeds
(vi) Use only native plant species for landscaping
(vii) Avoid fences. If necessary, use only wildlife friendly fences
(viii) Protect land west of the Roaring Fork to the maximum extent possible
b) Be considerate of other neighbors and users of the preserve
(i) Set development back to the maximum extent possible from North Star's boundaries.
The minimum setback should be no less than 100' from the North Star boundary
(ii) Locate development in areas that are visually screened from North Star by natural
landforms or vegetation
(iii)Minimize development, drainage, and erosion impact on the wetlands and river
(iv)Minimize noise from motorized equipment, radios, dogs, etc.
c) Preserve a '/a mile wide elk migration corridor to allow movement between Smuggler
Mountain and Richmond Ridge
d) Neighbors should consider the value of offering a conservation easement to North Star --
these include tax benefits, open space preservation and strengthening of natural
ecosystems
1.08 PUBLIC POLICY
Presently there are a number of state and local policies which restrict development in that
area based on environmental concerns. The following section summarizes these policies and
recommends additional legal conservation procedures.
A. Pitkin Board of County Commissioners Ordinance
North Star Nature Preserve Management Plan 21
93
A resolution to manage North Star according to the guidelines of the North Star Nature
Preserve Resource Management Plan 2000, should be adopted by the Pitkin County
Commissioners. This plan provides a base line management policy for North Star Nature
Preserve. Further development activity on adjacent properties should respect the
objectives stated in this plan since development on these properties may have significant
impact on the environment of the North Star. Therefore, review and approval agencies
need to be aware that this policy exists and that there are special areas of concern relative
to approval for development by adjacent landowners.
B. Zoning
The present zoning of the property is AFR-10. This theoretically permits one single
family dwelling unit per 10 acres. An application should be made to rezone the property
to a newly created zone district called something such as "Nature Preserve" or "Open
Space" based on the intent to conserve the land as open space and critical wildlife habitat.
C. Areas and Activities of Local and State Interest
Special review is required for development proposed in areas of local and state interest
which are specified in Section II, 5-400.2a of the Pitkin County Code. These include
floodplain and wildlife areas which exist at North Star. It is recommended that within
North Star no further development other than trails and signage be permitted in these
areas. Applications for private residential development in the Roaring Fork River Valley
should be subject to similarly strict review for the least possible impact on the
ecosystems. Lot owners should be encouraged to build both outside the floodplain and
the wildlife areas.
D. Clean Water Act Section 404
Any proposed development which will directly impact waters of the United States or
jurisdictional wetlands is subject to review by the U.S. Army Corps of Engineers and
Pitkin County. This type of development is currently prohibited by the Pitkin County
Land Use Code except where there is absolutely no alternative.
E. Water Rights
a) The North Star Agreement for Water Rights, Book 339, pages 543-544, should be
reviewed by an attorney and recommendations be made to ensure that those water
rights are maintained. This may mean maintaining the ditches leading to the
historically irrigated meadows.
b) Spring Water Rights should be researched and recommendations made.
F. Subsurface Rights
It should be determined whether subsurface rights exist which would affect North Star in
any way.
North Star Nature Preserve Management Plan 22
91-(
G. Easements and Rights-of-Way
Power line and utility easements on the property should be studied and the implications
reviewed.
H. Conservation Easements/Open Space and Trails Program Acquisitions
Neighboring property owners should be advised of incentives to donate land or
conservation easements to the Pitkin County Open Space and Trails Program (OST) to
extend the area managed for wildlife conservation. In addition, a conservation easement
for North Star should be given OST so as to ensure protection in perpetuity.
I. Colorado Department of Transportation (CDOT)
CDOT has specific regulations regarding development within the 60 foot right-of-way.
Communication should be maintained with CDOT regarding any rezoning as well as the
sensitivity of North Star. Additionally, CDOT should keep the County apprised of any
activities it is planning on Highway 82 where it borders North Star.
1.09 CONCLUSION
...in the end is the beginning...
T.S. Eliot
This Management Plan outlines key concepts and general directives for resource
management of North Star Nature Preserve with emphasis on North Star as a link in the Roaring
Fork Valley ecosystem. In order to ensure North Star and its environs are conserved as
undeveloped open space and critical wildlife habitat the recommended actions must be
implemented. This will involve the following measures:
A. Adoption of this plan by the Pitkin County BOCC,
B. Direction and implementation of this plan by the Pitkin County Open Space Department and
Assets Management Division,
C. Additional work by the Pitkin County Attorney's Office,
D. Adoption of policies by Pitkin County BOCC,
E. Cooperative development by neighbors of North Star.
The adoption of the concept of preservation of the west side of the Roaring Fork River, the
restrictions described herein, and the implementation of regulations for ecologically sensitive
development along the River corridor, as well as the proposed conservation easement will
ensure rich wildlife habitat and scenic vistas to be appreciated by the public who travel State
Highway 82, those using the proposed pedestrian trail and all neighbors to the North Star Nature
Preserve.
