INTRODUCTION
This report constitutes the Ecological Characterization Study (ECS) required for the proposed development of a RV and boat
storage facility within the Industrial zone district. This ECS was completed by AloTerra Restoration Services to address
requirements set forth in Article 3, section 3.4.1 of the City of Fort Collins Land Use Code.
PROPERTY LOCATION
The 105-acre property is located at the southeast corner of NE Frontage Road and an unnamed dirt road, with I-25 to the
west, the Larimer and Weld Canal, and Core and Main Waterworks Equipment Supplier to the south, and agricultural land to
the North and East. The Larimer and Weld Canal defines most of the southern edge of the property, while NE Frontage Rd.
defines the western edge. The center of the property lies approximately at 40.60400556 N Latitude and -104.99567500 W
Longitude.

PROJECT DESCRIPTION
The Front Range Storage – RV and Boat Facility project (hereafter referred to as “the project”) includes the development of a
10-acre outdoor and covered RV and Boat Storage lot, with the additional 95 acres remaining irrigated agriculture. To meet
development needs, the current infrastructure will likely be demolished and removed. There will be public access easements
constructed on the south and east borders of the facility, a right of way on the north border, and an 80 foot I-25 setback on
the west borer. The construction of a detention pond will also occur on the southeast corner of the facility, within the
irrigated agricultural land (Figure 2). During site assessments, AloTerra recorded an urban plains forest within the proposed
development containing 19 mature trees of primarily non-native species providing corridor habitat for a variety of wildlife
species. As a result of the facility, the non-native urban forest will be permanently impacted. There is one individual wetland
Ecological Characterization Study, Front Range Storage Page 3
on the property running adjacent to the Larimer and Weld Canal, comprising a total of 0.75 acres of wetland habitat (Figure
3). Current wetland vegetation will not be permanently impacted.

STUDY METHODS
In fulfillment of the ECS requirements set forth in Article 3, section 3.4.1 of the City of Fort Collins Land Use Code, AloTerra
staff acquired desktop data and conducted field surveys in support of our characterization of existing ecological and wildlife
conditions, as well as other natural features occurring on the site.
Ecological Field Assessment: 07/23/2023
Wildlife Field Review: 07/27/2023
Desktop analysis included reviews and interpretations of aerial imagery, assessment of regional drainage patterns, IPAC
database review (USFWS), and Colorado’s Conservation Data Explorer from the Colorado Natural Heritage Program (CNHP),
groundwater conditions, soil conditions, and location of nearby natural areas. Field assessments included qualitative rapid
assessments of native plant communities, weed populations, wetland and riparian areas, wildlife habitat conditions, and
indicators of current wildlife occupation. A formal wetland delineation was not performed, but rather a rapid wetland
assessment was performed, as the proposed development activities do not impact existing wetlands. The rapid assessment of
vegetation was performed to compile a list of dominant and co-dominant species, and species present in each community at
lower percent cover. For the purposes of this study, a plant was considered dominant or co-dominant if its relative cover is
greater than approximately 20%. Due to the homogeneity of the vegetation resulting from agricultural practices, ocular
assessments were conducted to characterize communities. Based on general disturbed site conditions, and the presence of
above ground features of the dominant species that are present, we are confident that this survey captured the species that
together represent approximately 98% of the above ground biomass of the site.

RESULTS
The results of the field and desktop assessments are described below, with the associated natural features represented in
Figure 3. Approximately 83% of the project site is characterized as historic agricultural fields, with about 17% of the site
dominated by exotic plants, or comprised of wetland and riparian communities in a degraded state (e.g., ditch-side wetlands
where concrete rip-rap provides primary substrate).

Proximity to Designated Natural Areas, Open Spaces, and Natural Habitats
The nearest Natural Area or Open Space is the Riverbend Ponds Natural Area approximately 2.25 miles to the southwest. The
nearest Natural Habitats are listed as Aquatic (Larimer and Weld Canal) running directly though the southern border. Other
natural habitats are Non-Native Upland Plains Forest along the northern border, and wetland habitats surrounding Boxelder
Creek to the East (Figure 4). These habitats will not be permanently impacted from the proposed development activities.

Site Description
From a historical perspective, prior to modern development, we believe the project site to have been dominated by short-
grass prairie within the Northwestern Great Plains ecoregion (level III ecoregion). Given the proximity of the property to the
Boxelder Creek floodplain, it is possible that the adjacent old growth cottonwood trees and associated understory riparian
vegetation typical of plains riparian ecosystems existed prior to agricultural development, though they may also be associated
with historic agricultural ditches. Currently, the upland areas are dominated by agroeconomic species, annual weeds, and
highly disturbed soils. The wetland and associated riparian areas are of low native species diversity, low community
complexity, and low structural diversity. The opportunity for wildlife to thrive in the existing conditions is low, with little
connectivity to adjacent habitats. Soil analysis revealed that agricultural disturbance has homogenized soils to generally a
sandy clay loam. The greatest native habitat features include the facultative wetland community and the non-native urban
forest on site. However, agricultural habitat is also very important to the agricultural roots and future sustainable
development of Larimer County.
Site Conditions and Status
The general ecological functions provided by the site and its features
The greatest ecological functions provided by the project site include sediment entrapment by the wetland and organic
matter production by the non-native vegetation. The urban forest also provides habitat for some bird species and insects,
though it is not a typical ecological condition of this ecoregion. The wetland and associated riparian habitat provide some
minor wildlife benefits, though those benefits are limited due to the highly fragmented condition of this small patch
surrounded by urban development.
Existing Soils
Desktop analysis via the USGS Web Soil Survey (WSS) revealed primarily clay loams with sandy loams. As these are historically
mapped soils, agricultural disturbance has homogenized these soils. There are no hydric soils historically.

Existing Infrastructure
Existing infrastructure includes access roads, two residential buildings, a 24” waterline that runs East/West through the center
of the site, and two primary culverts. There are buried utilities on the project site, which will be identified in future design and
construction phases. There is an electric utility on the eastern border, with subsequent transmission lines that parallel the
water line. The Larimer and Weld Canal constitutes the other primary infrastructure of the site.
Ecological Characterization Study, Front Range Storage Page 11
Topography
The project site is generally flat (< 5% slope). Greater slopes exist on the banks of the Larimer and Weld Canal (~40%). A
topographical map can be viewed in Figure 1.
Natural Habitats and Features with Significant Ecological Value
In this section we provide a checklist of required features as outlined in the ECS. No significant native plant communities were
documented on the site apart from the facultative and mesic meadow vegetation associated with the wetland and ditch-side
riparian community. The plant cover in the remainder of the site is dominated by non-native, agroeconomic species with low
structural and biological diversity.
Natural Communities or Habitats
Aquatic: yes; Wetland and wet meadow: yes; Native grassland: no;
Riparian forest: no; Urban plains forest: yes; Riparian shrubland: yes; Foothills forest: no;
Foothills shrubland: no
Special Features (enter present/absent, indicate on map, and describe details below):
Significant remnants of native plant communities: absent
Based on field conditions and analysis of aerial imagery, it is apparent no significant remnant native plant communities
exist on site. The existing riparian and wetland plant associates are a result of human-created topographic (e.g.,
stormwater drainages), hydrologic (e.g., irrigated farmland), and surface water alterations via the creation of a ditch.
Potential habitats and known locations of rare, threatened, or endangered species of plants: absent
No species of rare plants were observed during site visits. Due to agricultural activities and other current site conditions,
rare, sensitive, threatened, or endangered species are not likely to exist.
Raptor habitat features, including nest sites, communal roost sites and key concentration areas: present
Redtail hawks were heard.
Concentration areas for nesting and migratory shorebirds and waterfowl: absent
Not likely due to minimal aquatic habitat. However, ephemeral waterfowl use is likely in the canal, and one black
cormorant was noticed flying along the ditch.
Ecological Characterization Study, Front Range Storage Page 12
Migratory songbird concentration areas: absent
Not likely due to agricultural activities. One eastern kingbird was seen.
Key nesting areas for grassland birds: minor presence
Not likely due to agricultural activities. Two mourning doves were seen flying through the agricultural field and occupying
barren road conditions.
Fox and coyote dens: absent
Not noticed, but possible along canal banks.
Mule deer winter concentration areas: minor presen ce
Tracks were noticed along eastern road. However, due to habitat type and lack of connectivity to other deer habitats,
this is likely not a high concentration area.
Prairie dog colonies one (1) acre or greater in size: absent
Not present.
Concentration areas for rare, migrant, or resident butterflies: present
Concentrations of resident butterflies were noticed in dense patches of alfalfa.
Areas of high terrestrial or aquatic insect diversity: absent
Minimal diversity was present however, but species noticed include grasshoppers, mosquitoes, syrphid flies, and bumble
bees.
Areas of significant geological or paleontological interest: absent
A cultural and historical resources survey was not conducted as part of this assessment. However, based on the history
of the site and constant agricultural alteration, it is unlikely the site harbors significant cultural or historical resources.
The desktop analysis of soils revealed a diverse set of soils for a small area, which was not confirmed in the field due to
homogeneity resulting from agriculture.
Irrigation ditches that serve as wildlife corridors: present; not likely
Irrigation ditch (Larimer and Weld Canal) is present, but does not act as a wildlife corridor due to steep slopes with high
low diversity, high noxious species presence, and concrete rubble present throughout. Minimal potential exists for an
important wildlife corridor.
Other Important Features
Unobstructed views of mountains, rivers, or other notable landscape features: present
Ecological Characterization Study, Front Range Storage Page 13
Viewing west, there is an unobstructed view of the mountains including the Front Range and snow-covered peaks in July.
Pattern, species and location of any significant non-native trees.
Within the non-native urban plains forest, there is Norway spruce (Picea abies) and honey locust (Gleditsia triacanthos).
Within the wetland community there are Russian olive (Eleangus angustifolia) trees.
Special habitat features
The special habitat features on the project site include the wetland. However, the quality of the wetland is of poor condition
and function, and is likely 100% supported by anthropogenic hydrology resulting from canal seepage, highway run-off, and/or
overflow water from historic cattle troughs.
Habitats and Plant Communities
The subsections below outline the conditions of habitats existing on site: wetlands, agricultural communities, and uplands.
Refer to Figure 3 for locations of these features.
Wetland and Riparian Communities
AloTerra identified wetlands on site, however a formal wetland delineation was not completed. Also completed, was a
review of other aquatic features such as ponds and streams. Because the vegetation and hydrology were primarily non-
native, and field indicators of an Ordinary High-Water Mark (OHWM) were weak due to the artificial concrete dominated,
steep banks, we did not perform an Ordinary High-Water Mark (OHWM) survey.
Wetland
The wetland is likely an anthropogenic wetland supported by groundwater seepage from the Larimer and Weld Canal,
run-off from adjacent I-25, and/or a historic cattle trough. However, the area was assessed based on the presence of
Facultative (FAC), facultative-wet (FACW), and some obligate (OBL) vegetation. Very low plant and structural diversity
exists in this wetland, with very poor wildlife value. The dominant vegetation across all strata (herb, vine, and shrub/tree)
is comprised of plants common threesquare (Schoeonoplectus punges; OBL), arctic rush (Juncus arcticus; FACW), tall
scouring rush (Equisetum hymale; FACW), showy milkweed (Asclepias speciosa; FAC), and facultative upland (FACU) plants
smooth brome (Bromus inermis), meadow fescue (Festuca pratensis), Canada thistle (Cirsium arvense), and Curly dock
(Rumex crispus). Also present in the canopy was Russian olive (Eleangus angustifolia; FAC ) however there seemed to be a
recent treatment and removal Russian olive. Smooth brome was the dominant cover, accounting for approximately 80%
of vegetation. Soil pits were not dug to identify whether hydric soils were present.
Larimer and Weld Canal
Larimer and Weld Canal was anthropogenically created, likely to support agricultural lands in the plains of Colorado.
Minimal native vegetation habitat was present along the banks or within the stream. The stream is characterized as
Ecological Characterization Study, Front Range Storage Page 14
primarily non-native with minimal sinuosity, steep banks, poor floodplain connectivity, and construction debris serving as
“riffle” structures and bank stabilization. Ecological value is low with minimal vegetative and structural diversity.
Dominant species along canal banks include: reed canarygrass (Phalaris arundinaceae), Emory’s sedge (Carex emoryi),
smooth brome (Bromus inermus), and kochia (Bassia scoparia). Additional present species include common mullein
(Verbascum thapsis), prickly lettuce (Lactuca serriola), Canada thistle (Cirsium arvensis), squirreltail (Elymus elymoides),
curly dock (Rumex crispus), cheatgrass (Bromus tectorum), leafy spurge (Euphorbia esula), and various annual mustards.
Agricultural Communities
Agricultural Community - 1
The project site is highly disturbed and predominately vegetated with agroeconomic species. The community is densely
vegetated forming a monoculture (~95%) of common oat (Avena sativa). Other species present in small quantities (mostly
along borders) include corn (Zea mays), alfalfa (Medicago sativa), amaranth species (Amaranthus spp.), Bermuda grass
(Cynodon spp.), foxtail species (Setaria spp.), common purslane (Portulaca oleracea), and kochia (Bassia scoparia). Due to
the high cover of non-native vegetation, and low diversity of structure, the wildlife value of this field is very low.
Agricultural Community - 2
This community did not seem to be currently active as an agricultural field. Due to the cover, and presence of
agroeconomic species, AloTerra assumes consistent use for agricultural purpose. Dominant species include alfalfa
(Medicago sativa) and kochia (Bassia scoparia). Also present in small amounts was Bermuda grass (Cynodon spp.). Due to
low species and structural diversity, the wildlife value is very low. Large amounts of alfalfa correlated to an increase in
pollinator value from Agricultural Community – 1.
Upland Plant Communities
Kochia - 1
Upland areas are highly disturbed and predominately vegetated by non-native flora. Minimal pollinators were noticed,
and species diversity was low. Due to the high cover of bare ground, high cover of non-native vegetation, and low
diversity of structure, the wildlife value of this field is very low. Dominant species include Kochia (Bassia scoparia),
goosefoot (Chenopodium sp.), puncture vine (Tribulus terrestris), and field bindweed (Convululus arvensis). Additional
species presence includes prickly lettuce (Lactuca serriola), foxtail species (Setaria spp.), sow thistle (Sonchus), cutleaf
vipergrass (Scorzonera laciniata), poinsettia plant (Euphorbia spp.), and Russian thistle (Salsola iberica).
Non-Native Grassland
This upland community is in an extremely degraded state, with historic signs of cattle grazing (trough). Minimal species
and structural diversity are present, with a dominance of non-native grasses. Approximately 80% of the community is
Ecological Characterization Study, Front Range Storage Page 15
composed of smooth brome (Bromus inermis), with minor presence of meadow fescue (Festuca pratensis), Kochia (Bassia
scoparia), Canada thistle (Cirsium arvense), and cheatgrass (Bromus tectorum). Wildlife value is very low.
Non-Native Upland Plains Forest
The community is anthropogenically created, surrounding the current infrastructure. As structural diversity is low
throughout the property, this location provides the only nesting habitat for most birds. The 19 trees are a mix of Norway
spruce (Picea abies), Ponderosa pine (Pinus ponderosa), and honey locust (Gleditsia triacanthos). The understory is
primarily smooth brome (Bromus inermis).
Turf Grass
Adjacent to the current infrastructure stands a mowed stand of turf grass which is approximately 90% smooth brome
(Bromus inermis). Minimal other vegetation exists, with no other structural diversity. Wildlife value is very low.
Staging Area
This location is currently being used as a staging area for agricultural operations such as straw, equipment, fencing
material, etc. It will likely continue to be used as staging and access during construction of the storage facility.
Approximately 90% of the ground is bare, but there is a presence of weedy annuals and some native species. Species
present at low concentrations include Kochia (Bassia scoparia), goosefoot (Chenopodium sp.), common sunflower
(Helianthus nutans), and cheatgrass (Bromus tectorum). Wildlife value is very low.
NOXIOUS WEEDS
A preliminary weed (non-native plants) list is provided in the wetland, riparian, and upland plant community sections above.
Of the weeds present, those species of greatest management concern include smooth brome (Bromus inermis), Canada thistle
(Cirsium arvense), kochia (Bassia scoparia), and reed canary grass (Phalaris arundinaceae).
Wildlife Review
Background
The proposed Front Range Storage Facility (hereafter referred to as The Project) is in Fort Collins, Colorado on Larimer County
land (Figure 1) at approximately 4,990 feet in elevation. A 105-acre property sits adjacent to I-25 north and Frontage Rd and is
bordered by the Larimer and Weld County Canal to the south and E Co Rd 50 to the north. The Project largely consists of old
agricultural fields and is surrounded by Industrial and private lands to the south and a small parcel of Colorado Division of
Wildlife land to the north.
Ecological Characterization Study, Front Range Storage Page 16
On July 27, 2023 AloTerra Restoration Services (AloTerra) determined an approximately 0.75-acre facultative wetland south of
the canal that was dominated by smooth brome (Bromus inermis) with pockets of showy (Asclepias speciosa), arctic rush
(Juncus arcticus), horsetail (Equisetum hymale), and three-square (Schoenoplectus pungens). The canal that flows east through
the southwestern corner is defined by steep grades lined with reed canarygrass (Phalaris arundinaceae), Emory’s sedge (Carex
emoryi), and smooth brome (Bromus inermus) with low presence of horsetail (Equisetum spp.), and Kochia (Bassia scoparia).
The adjacent upland is dominated by smooth brome (Bromus inermis) with pockets of common sunflower (Helianthus nutans),
cheatgrass (Bromus tectorum), and alfalfa (Medicago sativa). The western portion of the project north of the canal contains
existing structures surrounded by 19 mature deciduous and conifer trees. The species consist of one Norway spruce (Picea
abies), Ponderosa pine (Pinus ponderosa), and honey locust (Gleditsia triacanthos). To the east of the structures lies
agricultural fields dominated by common oat (Avena sativa) with residual corn (Zea mays), alfalfa (Medicago sativa),
amaranth species (Amaranthus spp.), and kochia (Bassia scoparia).
The proposed construction plan comprises of developing 10 acres of land for a recreational vehicle and boat storage facility.
Construction will take place north of the Larimer and Weld County Canal on the 104-acre property and will be accessed on the
west side via NE Frontage Rd. The remaining 95 acres to the east side will remain and be used for agricultural purposes. A
large detention pond is proposed to be built south of the facility and public access buffers are designed to line the facility on
the south and east side.

Purpose
The purpose of this wildlife review is to assess the probable effects on federally listed species and sensitive species in The
Project site, per Section 7 of the 1973 Endangered Species Act. Under the actions, consultations, and recommendations of the
USFWS, in cooperation with Colorado Parks and Wildlife. The authorized organization must ensure, with the best scientific
data available, that there will be no negative change or destruction to critical habitats in The Project area (USFWS, 2013).
Threatened, Endangered, and Proposed Species
On July 29, 2023 an official species list was documented by U.S Fish and Wildlife Service’s Information for Planning and
Consultation (IPAC: http://ecos.fws.gov/ipac/). Information was obtained by using known ranges of federally listed species in
the project area. A list was also unofficially obtained from the 2016 Colorado Natural Heritage Program (CNHP) database by
looking at known sightings of sensitive species near The Project area. CNHP’s Colorado's Conservation Data Explorer (CODEX)
was utilized as an additional resource to assess the possibility for sensitive habitats and wildlife corridors. On July 27, 2023 an
AloTerra Restoration Services field technician conducted a site visit in order to assess suitable habitat for known listed and
sensitive animal species.
Table 1 provides a record of the Federally listed species that could occur within the area of the proposed project (104 acres).
The table includes (a) the common name of the species (b) the scientific name of the species (c) the status of the species in
question (d) whether the species should be excluded, and (e) an explanation for the resulting exclusion.
The reasoning of excluding species from the list of concerned species is given based off a variety of reasons including:
1) No suitable habitat was found during site visit, The range of the species in is such that the species is highly unlikely to not
known near occur within The Project site;
2) No suitable habitat was found during the site review; and/or
3) No records for the species exist within The Project site.

Federally Threatened, Endangered, and Proposed Species
Preble’s Meadow Jumping Mouse (Zapus hudsonius preblei)
Since 1998, the Preble’s Meadow Jumping Mouse (Zapus hudsonius preblei; PMJM) has been federally listed as threatened
by the U.S Fish and Wildlife Service. In Colorado, they are also listed as Species of Greatest Conservation Needs, considered
sensitive by the US Forest Service, and critically imperiled according to the CNHP. Declining PMJM populations are due to
predation, habitat degradation, and fragmentation. In Colorado, the PMJM can be found up to elevations around 7,000 feet
east of the Front Range, and west to the shortgrass prairie. (USFWS, 2013)
Preble’s meadow jumping mice are found in areas with natural hydrological processes that create a dense riparian area
with biologically diverse herbaceous plants. PMJM have been found in environments with a variety of plant species,
frequently in areas with a thick layer of grasses and forbs that create cover. Studies show that the specific species
composition of herbaceous plants is not as important to supporting populations, but that suitable habitat needs to have a
higher percentage of ground cover in the vicinity to open water. Most PMJM were found within areas with a higher density
of the shrub layer consisting mostly of willows. The mice use adjacent grassy uplands as far as approximately 300 feet from
the 100-year floodplain to “hibernate” during the colder months. These nests are called hibernacula and can be found
under the cover of snowberry, chokecherry, cottonwoods, gooseberry, and other willow species.
Section 4 of the Endangered Species Act (1973) prevents any funded or authorized agency to take action that would
negatively affect lands labeled as PMJM Critical habitat. Critical Habitat is defined by areas currently occupied by the
species or potential areas in which the species could establish. In 2013, The Fish and Wildlife Service revised the critical
habitat designation for the Preble’s meadow jumping mouse (shapefiles found at: https://www.fws.gov/mountain-
prairie/es/species/mammals/preble/CRITICAL%20HABITAT/CRITICALHABITATindex.htm.). The approximate 50,000 acres
designated for critical habitat occur adjacent to streams and rivers in the Colorado foothill and mountain regions. PMJM
critical habitat is located in Boulder, Broomfield, Douglas, El Paso, Jefferson, Larimer
and Teller Counties (USFWS, 2014). Currently there is no critical habitat designated in The Project area (USFWS, 2010). The
project area does not have optimal habitat due to lack of desired upland and riparian vegetation and desired hydrology,
presence of PMJM were not noticed, and are not likely.
Rare Plants
The rare plant surveys conducted on July 23 and 27, 2023 resulted in no evidence of Ute ladies’-tresses (Spiranthes diluvialis)
or Western prairie fringed orchid (Plantanthera praeclara) in the project area.
Sensitive Species
The sensitive species list is derived from the U.S. Forest Service (https://www.fs.usda.gov) and Colorado Parks and Wildlife
data on present sensitive species ranges and distributions (USFS, 2005). The Regional Forester’s sensitive list is evaluated by
examining viable risk of species; these species are categorized as R2 sensitive, not R2 sensitive, or, not a concern. Suitable
habitat was also determined by a site visit conducted by AloTerra Restoration Services on July 27, 2023. Under the Migratory
Bird Treaty Act of 1918 and the Bald and Golden Eagle Protection Act no activity that “takes, transports, barters, or exports
the listed migratory birds or eagles is permissible unless it is sanctioned by the U.S. Fish and Wildlife Service. The sensitive
species list includes migratory birds that could use The Project area as a breeding, over-wintering, or stopover site.
The species found in Table 2 below are compiled from lists of at-risk species that have potential habitat or occurrence in The

Sensitive Species Information
Mammals
Townsend Big-eared Bat
The Townsend big-eared bat (Corynorhinus townsendii) range through western Canada down to Mexico and can be found up
to 10,800 feet in elevation. There population numbers have declined due to roosting loss that have stemmed from large mine
closures and cave disturbance. (Ellison et al., 2003). These bats are found in all habitat types across Colorado including riparian
corridors, aspen stands, juniper woodlands, and sagebrush/grass steppe with lower percentages found in mixed conifer.
(Ulrich 1986). The bats require habitat with spacious caves or cave-like structures for roosting and are very sensitive to
disturbance at roost sites. Diet mostly consists of insect species, including moths, flies, and beetles and foraging locations are
not found far from their roosts. (Adams 2003). The site visit conducted by AloTerra on July 27, 2023 found no suitable habitat
near the proposed construction site. Due to the location of the proposed project the Townsend big-eared bat should not be
adversely affected.
Swift Fox
Historically, swift fox (Vulpes velox) populations declined due to habitat fragmentation and loss, competition, trapping, and
collateral damage when trying to kill wolves. In Colorado, they are listed as Special Concern and classified as a sensitive
species by USFS Region 2. They range throughout western United States but are found in higher abundances in Colorado than
Montana, Nebraska, and South Dakota, where they still have not reached historical population levels. The fox appears to not
be affected by heavily grazed ecosystems and can be found in a variety of habitat types that include short-grass and mid-grass
prairies, including a variety of agricultural land types. In these areas, vegetation is typically dominated by blue grama,
buffalograss, western wheatgrass, and sagebrush. Fox dens have been found in areas with low vegetation on slight slopes in
well-drained sites, with soil types that include silty loam or loam. The species are not directly reliant on riparian areas and can
be found up to 3 miles away from any source of water. (Marks et al., 2005). No dens were sighted in The Project area. Due to
the size of the proposed project area, there should be minimal impacts to swift fox populations.
Birds
Bald Eagle
The bald eagle (Haliaeetus leucocephalus) is found only in North America (CPW, n.d.). Populations declined in the early-mid
20th century due to impacts from pesticides (mainly DDT), disturbance and loss of trees for nesting habitat. The eagle was
Ecological Characterization Study, Front Range Storage Page 21
consequently placed on the Endangered Species List. However, with the ban on the pesticide DDT and protection of nesting
habitat, the eagles have substantially recovered, with Endangered status reduced to Threatened in 1995 and with further
recovery was de-listed nationally. The bald eagle was removed from the Colorado list of threatened and endangered species
in 2009. Bald eagles can be found throughout much of Colorado during both summer and winter and can be observed near
reservoirs and major rivers such as the South Platte River and the Poudre. Eagles will roost and nest in large cottonwood trees,
roosting communally in the winter for warmth. Bald eagles have a varied diet, with nests often found near water in tall trees,
building nests that can be 7 to 8 feet across. (Swenson et al., 1986) No nests or signs of bald eagles were seen during site visits
on July 23 or 27, 2023. Any bald eagles that may be using the area should not be negatively affected by the project, especially
if large trees can be protected from construction activities.
Long-billed Curlew
Long-billed curlews (Numenius americanus) breed in shortgrass and mixed-grass habitats, and occasionally in agricultural
fields. They feed primarily on grasshoppers and other invertebrates. The breeding range in extensive; from British Columbia to
Northern Texas. In Colorado, they primarily occupy the eastern plains, with individual territory range of 15-35 acres. (Mowat
1984) The birds arrive in Colorado to breed beginning of April and chicks fledge by June whereby adults usher the young from
short grass to taller grasslands to protect the young birds from predation. By mid-July the breeding adults leave behind the
young of that year for winter grounds along the California-Baja coast. Although long-billed curlews nest in dry areas, they do
appear to need significant bodies of standing water nearby for reproductive success (Jones et al., 2008). The July 23 and 27,
2023 surveys conducted by AloTerra Restoration Services found no nests. Due to the minor size and duration of the proposed
construction, long-billed curlew populations should be minimally impacted.
Northern Harrier
The northern harrier (Circus cyaneus) is a “Tier 2 Species of Greatest Conservation Need” in Colorado and a USFS Sensitive
Species in Region 2. These raptors reside in a variety of habitats year-around, including grasslands and marshes. They reside
throughout Colorado, with higher densities on the eastern plains, short-grass prairies, and western valleys. In the eastern
plains these birds breed in a variety of ecosystems, preferring large wetlands (>250 acres) with dense vegetation (7-10 inches
in height). Nests are found either on the ground or on a platform usually near open water. More specifically, nests are
commonly found hidden in wetland vegetation, where cover is taller than 60 cm. (Slater, 2005) During the site visits on July 23
and 27, 2023 no northern harriers were sighted, and no suitable nest habitats were found. The project development is unlikely
to negatively impact the species due to the species range and scope of the proposed construction.
Swainson’s Hawk
The Swainson’s hawk (Buteo swainsoni) is found throughout Colorado in open areas, usually native short and tall grass
prairies, and agricultural lands and less likely to be found in mountainous regions. Since the 1980s, Swainson hawk
populations declined in many parts of its range due to removal of riparian habitat, and lack of nest site availability (Bechard,
2010). The raptors’ home range varies between about 170 to 21,550 acres depending on the amount of forage and water
available. Nests will frequently be found in a lone tree or post in these grasslands, but they can also be found along riparian
areas among a cluster of trees within their home range. The nests are found in a variety tree species including cottonwood
(Populus sp.), willows (Salix sp.), sycamores (Platanus sp.), and walnut (Juglans sp.) These hawks are a migratory bird species,
listed on the Migratory Bird Treaty Act, traveling from North America to breed in the summer to South America for wintering.
(Woodbridge, 1998) This raptor has a high tolerance for human disturbance and can be found in areas with high human
activity, although there can be nest abandonment if there is high-intensity disturbance or construction near a nesting tree.
When nests occur, they are usually found 15-30 feet above ground. AloTerra Restoration Service’s wildlife technician
conducted a field assessment on July 27, 2023 and found no nests in the project area. The Swainson’s hawk should not be
negatively affected by the project due to the extensive size of their home range and minimal effect to potential nesting sites
from construction activities.
Ecological Characterization Study, Front Range Storage Page 22
Amphibians
Northern Leopard Frog
Northern leopard frogs (Lithobates blairi) are found statewide in Colorado and are currently listed as a Tier 1 Species of
Greatest Conservation Need. Population declines are due to climate change, invasive diseases, habitat loss, pollution, and
predation. The frogs can be found in the western United States in elevations up to 11,000 feet. This species can inhabit a
variety of riparian areas including stream channels, sloughs, reservoirs, gravel pits, and oxbows. For breeding and foraging
purposes, the frogs prefer dense vegetation with heights around 6 to 12 inches and more than 30 percent cover. Northern
leopard frog breeding sites commonly occur in semi-permanent ponds or wetlands with water depths to 25 to 40 inches.
Water quality is also an important factor for most amphibians, needing unpolluted sites with water that is well oxygenated
and pH balanced (6.1-7) (CPW, 2005). Through the winter, leopard frogs hibernate on the bottom of ponds located beneath 1-
1.5 feet of rock where water depths were at least 2 feet. Construction associated with the project will have minimal impacts
on individuals given the time of the construction and minimal suitable winter habitat.
Insects
Monarch Butterfly
The Monarch butterfly (Danaus plexippus) is a candidate for official listing as of December 2020 and is Region 2 Forest Service
Sensitive Species in Colorado. (USFS 2015). It is estimated that eastern subspecies of Monarch populations have declined by
over 80% over the last several decades due to climate change and loss of foraging and overwintering habitat. Studies have
shown that habitat loss has been largely linked to agricultural development and weed management. (Reichstein et al., 1968).
The Monarch butterfly is found in a wide variety of habitats in Colorado including meadows, prairies, montane, and alpine and
can be found in elevations up to 11.000 feet. (Thogmartin et al., 2017). They are more commonly found in lower elevations in
south/central Colorado where their larval plant is found during their latitudinal migration in mid-June to September. The
butterflies lay their eggs on milkweeds (Family Asclepias), a plant that contains a milky latex substance called cardenolides
that is toxic to humans and most other species. The Monarch’s lifecycle (from egg to caterpillar, to chrysalis, then back to
butterfly) can take up to 40 days and be as quick as 17 days. The adults can live from 2 to 5 weeks, while some in colder
climates can suspend their reproduction and live up to 9 months. (Thogmartin et al., 2017). On July 27, 2023 AloTerra
recorded potential breeding sites south of the Larimer and Weld County Canal just south of the proposed construction area.
Due to the schedule and location of the proposed construction the monarchs butterfly should not be adversely affected
towards significant population decline.
Wildlife Effects and Mitigation Measures
In order to mitigate possible harm to wildlife during the proposed project construction, locations of listed or sensitive species
must be identified and mitigation measures should be put in place. During the July 27, 2023 site visit, several nests were
identified. Swallow nests were located under the bridge on the southwestern border and mourning dove and western kingbird
nests were found in the spruce and pine trees near the building structures onsite. No ground nests, raptor nests or prairie dog
colonies were found within The Project area. Many common animal species have been observed throughout The Project
including garter snakes, American Robins, golden finches, and House sparrows but The Project does not provide any critical
habitat to federally listed or sensitive species. The following mitigation measures should be implemented when possible.
Mitigation Measures
• Avoid destruction of any large trees that contain nests or cavities that could provide nesting sites.
• A mitigation plan for any large trees impacted should be created and implemented.
Ecological Characterization Study, Front Range Storage Page 23
• If sensitive species nesting activity is detected, ensure guidelines for species protection are met (i.e., relocation,
avoidance of destruction).
• If construction is taking place adjacent to a wetland employ best practices to mitigate harm.
• Install silt fencing upslope of the wetland or adjacent to any drainage ways that lead to the wetland.
• Protect upland vegetation bordering the wetland as a buffer to slow runoff and filter sediment.
DEVELOPMENT ACTIVITIES
The project is currently in the Concept Site Planning phase. AloTerra is not aware of a current estimate for project
construction timeline.
Issues regarding the timing of development-related activities stemming from the ecological character of the area.
Because no active raptor nests exist on site, and the site does not provide significant migratory bird habitat, it is not likely that
construction limitations would be imposed. No other issues regarding timing are known currently. Further detail regarding
timing estimates for mobilization to the site is required to assess potential risks.
Measures needed to mitigate projected adverse impacts of development on natural habitats and features.
Since there are no proposed impacts to the identified wetland, a formal wetland survey is not needed, and mitigation is not
required. Due to the potential loss of nesting habitat resulting from the destruction of the non-native urban plains forest,
AloTerra recommends that a mitigation plan is created and implemented. All removed trees should be replaced at a 1:1 rate
with native plains tree species, such as plains cottonwood (Populus deltoides var. monilifera), and tall shrub species such as
peachleaf willow (Salix amygdaloides), as well as native plains riparian shrubs.
SUMMARY
In summary, we believe that the proposed development, would have minimal impact to sensitive or rare wildlife or plants,
natural features, and other important ecological functions and conservation elements in the region. A potential mitigation of
lost trees with native species would create overall ecological uplift of the site and enhance the quality of plant communities
and connectivity of habitat for wildlife. Because the site is currently predominately covered in invasive species, the value to
wildlife is not significant cont aining minimal structure and function.
