Introduction The Burnett Oil Company has submitted an application for permit to drill for the West Bridger Lake Unit
(WBLU) #1-3 well on the Evanston-Mountain View Ranger District. To analyze the proposal, the Uinta-
Wasatch-Cache National Forest will undertake an environmental assessment to analyze the impacts of the
proposed action on surface resources. The Bureau of Land Management (“BLM”) will be a cooperating
agency with the Forest Service and will analyze subsurface impacts. In addition, BLM personnel with
particular areas of expertise, such as air quality, will assist with surface analysis when appropriate.
Burnett Oil Company proposes to drill a test well on surface land managed by the Forest Service and
minerals managed by the BLM. No existing facilities are found on the proposed well site. The proposed
well site lies within a unit harvested via a clear cut in 1995.
A graded well pad with a maximum dimension of 600 feet by 600 feet would be constructed, depending
on the rig and operational design requirements. To minimize surface disturbance, a portion of the
constructed area outside the well head, associated tankage, and access road would be reclaimed and
reseeded after drilling and operations on the lease are completed and further development is not
anticipated. All areas would be reclaimed and reseeded after the well is plugged and abandoned. Spoil
and top soil pile areas would not be scrapped during construction. Spoil and top soil piles would be
divided physically to prevent mixture.
Drilling would determine whether oil and/or gas production is possible and economically feasible. The
test well would target the Nugget Formation at a depth of approximately 18,600 feet. All oil, gas, and
water production from the wells would be measured at the well site.
During operations, surface facilities at the well site are anticipated to consist of a well head, four 400-
barrel tanks, and production separator and dehydration unit if necessary. The wellbore may have a
pumping unit installed to pump oil from the formation. Exposed surface facilities would be painted shale
green or a color approved by the Forest Service.
The size of surface facilities depends on the success of the well. Therefore, if the well is productive, a
sundry would be filed with the Forest Service showing the actual production facility layout diagram. At a
minimum the well site layout would provide for facilities only on the disturbed area in minimal cut no
closer than 25 feet from a back slope with containment structures having a holding capacity of 110
percent of the largest fluid container.
All operations associated with the well would comply with Onshore Order #1 and #1, BLM Manual 9113,
and the Forest Service Gold Book Standards, unless otherwise proposed and shall conform to the site
specific reclamation plan submitted by Burnett Oil Company.
If the well is found to be unproductive, it would be plugged and abandoned as soon as practical after the
conclusion of production testing.
No new roads would be needed for access to the test well. Burnett Oil Company shall improve
approximately 1.5 miles of Forest Road 388. Up to 15 miles of road would be temporarily improved with
gravel for equipment access. After the well is completed, travel normally would be limited to one visit per
day. If the well is productive, the access route would be resurfaced with gravel acceptable to the Forest
Service to allow for all-weather access.
2
Water used for drilling, completing the proposed well, and dust control would be obtained from a water
well that Burnett Oil Company proposes to drill on the site. If additional sources of water are required,
the operator would obtain needed water from a diversion on Gilbert Creek approved by the Forest
Service. Water volume used for the well proposal is estimated at 100,000 barrels but depends on the
depth of the well and losses that might occur during operation. Authorization to appropriate water as part
of the proposal would be obtained from the Utah State Engineer’s Office.
No construction materials would be needed for drilling purposes. There are no plans to use any material
obtained from National Forest System lands. Construction and drilling would not be conducted using
frozen or saturated soils. If production is successful, gravel would be purchased from a local supplier and
spread on the roadway and the well site to maintain all-weather travel.
Additional activities associated with the proposal that should be reviewed during the environmental
analysis are found in items 1 through 12 in Appendix A, which captures the proposal as presented in the
application for permit to drill.
Water-based cuttings will be placed in the reserve pit during drilling. A wire fence will be installed
around the pit during drilling (three sides) and on all four sides after the drill rig leaves the site. Pit
closure and reclamation are discussed later in this document. Oil-based cuttings will be placed in above-
ground leak proof-steel tank(s) and promptly removed from the national forest. For more information on
pits, see APPENDIX F: FOREST SERVICE OIL AND GAS PIT SITING CONSTRUCTION AND
CLOSURE GUIDANCE.
Alternative 1 (No Action) Under the no action alternative, there would be no exploration drilling occurring within the proposed
project area.
Alternative 2 (Proposed Action) Burnett Oil Company proposes to drill a test well on surface land managed by the Forest Service and
minerals managed by the BLM. No existing facilities are found on the proposed well site. The proposed
well site lies within a unit harvested via a clear cut in 1995.
A graded well pad with a maximum dimension of 600 feet by 600 feet would be constructed, depending
on the rig and operational design requirements. To minimize surface disturbance, a portion of the
constructed area outside the well head, associated tankage, and access road would be reclaimed and
reseeded after drilling and operations on the lease are completed and further development is not
anticipated. All areas would be reclaimed and reseeded after the well is plugged and abandoned. Spoil
and top soil pile areas would not be scrapped during construction. Spoil and top soil piles would be
divided physically to prevent mixture.
Drilling would determine whether oil and/or gas production is possible and economically feasible. The
test well would target the Nugget Formation at a depth of approximately 18,600 feet. All oil, gas, and
water production from the wells would be measured at the well site.
During operations, surface facilities at the well site are anticipated to consist of a well head, four 400-
barrel tanks, and production separator and dehydration unit if necessary. The wellbore may have a
pumping unit installed to pump oil from the formation. Exposed surface facilities would be painted shale

Approximately 15 miles of existing Forest Road 388 would be improved.
Assumptions and Methodologies of Analysis
Key Assumptions and Methodologies Assumptions for the evaluation of effects on the species analyzed are made based on drainages and
topography of the project area. Disturbance may vary among species and individuals based on varying
environmental conditions, disturbance and the associated response of a species. These are disclosed in
the discussions of the individual species groups.
Disclosure of Methodologies
The method for analysis for this report is to present the desired conditions for the resources from the
Wasatch-Cache National Forest Revised Forest Plan (2003) and describe the potential effects and impacts
4
of the proposed action to the various wildlife species that are known to inhabit or could potentially inhabit
the proposed project area.
Consideration of Best Available Science The Uinta-Wasatch-Cache National Forest (UWCNF) is required to evaluate potential effects from the
proposed project on Management Indicator Species (MIS), Regional Forester’s Sensitive Species,
migratory birds, and any species federally listed under the Endangered Species Act (ESA). This document
uses the best available science to analyze the current environment and potential impacts from the project
alternatives. Data available for this analysis includes Utah Division of Wildlife Resources (UDWR)
habitat and big game data, Wyoming Game and Fish Department (WGFD) big game data, MIS reports,
and surveys conducted by the Forest Service and others.
Big Game Species The proposed project area falls within the state jurisdictional boundary of the Utah Division of Wildlife
Resources (UDWR). The most recent data (habitat polygons) were downloaded August 2014 for analysis
of the project area. A variety of big game species inhabit the project area include mule deer (Odocoileus
hemionus hemionus), elk (Cervus elaphus nelsoni), moose (Alces alces shirasi),and pronghorn
(Antilocapra Americana). General information about each species within the project area is discussed
below.
Elk Elk are a generalist ungulate with a diet consisting of grasses, forbs, and shrubs, and thus inhabit a variety
of habitat types within Utah and Wyoming. During summers, they prefer higher elevations in
aspen/conifer forests. In winter, they inhabit mid to low elevation habitats that are primarily comprised of
sagebrush and shrub communities (UDWR 2010b).
The elk in the North Slope Harvest Unit have been classified as an interstate herd summering in Utah and
wintering in Wyoming. Annual variations in elk movements from summer ranges (Utah) to winter ranges
(Wyoming) are dependent upon winter weather severity.
The UDWR classifies the project area as mostly crucial summer (calving habitat) and some crucial winter
habitat. The elk population on the North Slope Harvest Unit (North Slope Summit) meets the population
objective of 300 animals. Despite losses of crucial habitat throughout Utah, elk numbers within three
subunits of the North Slope Harvest Unit have been near or above the collective population objective of
2,100 since 2005 (UDWR 2010b).
Mule deer Mule deer forage on a diversity of plants (browse, forbs, and grasses) and thrive in early successional
habitats (WAFWA 2003). Tree-dominated habitats offer mule deer thermal cover from severe weather,
but provide little foraging opportunities. A mosaic or pattern of habitats can provide both, food and cover.
Thick brush and trees provide ungulates with cover, while the small openings provide forage and feeding
areas (UDWR 2008).
Herd numbers in Utah have been below objective statewide since 1994 when a combination of factors
including drought, heavy winters, and degraded winter habitat caused mule deer populations to crash
statewide. Herd numbers have slowly increased from 1994-2003. In 2003, deer numbers again decreased
statewide when several years of drought condition led to lower fawn production. This extended drought
was also a factor that allowed fire to burn on many deer winter ranges causing loss of resources for deer
5
during the critical winter months. From 2008 to 2010, the mule deer population on the North Slope unit
increased from 4,800 to 6,200 animals. The proposed project area is classified as crucial summer habitat
by the UDWR.
Moose The Shiras, or Wyoming moose, the smallest of four subspecies, inhabits Utah and Wyoming, Aspen,
willows, and a variety of aquatic emergent and submergent vegetation are preferred forage species for
moose. Wet meadows and riparian habitat are important for cow moose and calves during the summer.
Moose habitats in Utah and Wyoming are associated with riparian and wetland areas and upland areas
dominated by mountain mahogany (Cercocarpus spp.), Gamble oak (Quercus gambelii Nutt),
serviceberry (Amelanchier arborea), quaking aspen, and burned over coniferous forests (UDWR 2009).
Moose habitat in the proposed project area is classified as crucial winter by the UDWR. The herd in Uinta
County, Wyoming is jointly managed with Utah on the north slope of the Uinta mountain range. The
post-season population objective is 900 moose. UDWR funds an interstate elk and moose survey every 3rd
year. In 2010, the survey was postponed until January 2011 because of snow conditions. During the
survey, 324 moose were counted between the North Slope hunt unit and Wyoming hunt areas 27 and 35.
Between the 2007 and the 2011 survey, field observations, comments from landowners and sportsmen,
and reduced nuisance moose or damage complaints all suggest the herd has experienced a sharp reduction
in this moose population (WGFD 2010).
Pronghorn
Pronghorn populations are currently established in suitable habitats throughout Utah primarily the
shrubsteppe plant community. Large expanses of open, low rolling or flat terrain characterize the
topography of most of those habitats. Sustaining pronghorn populations requires a vegetative mix with a
strong forb component (Yoakum 2004b). Succulent forbs are essential to lactating does and fawn survival
during the spring and early summer (Ellis and Travis 1975, Howard et al. 1990). High quality browse,
protruding above snow level, is especially critical to winter survival of pronghorn (Yoakum 2004b). The
proposed project area falls within the North Slope (Summit) Herd Unit. The latest report does not indicate
a population estimate; however, both the 5-year and 10-year trends indicate the population is stable
(UDWR 2009). The North Slope/West Daggett herd unit has a population estimate of 800 animals and
both the 5-year and 10-year trends indicate the population is stable (UDWR 2009).
Impacts to big game
A variety of disturbances can impact big game temporarily or long term depending upon the activity,
timing and duration. Potential impacts to big game would be relatively similar in nature for all species
discussed. A summary of potential impacts to big game are shown below.
Potential Impacts to Big Game include:
Decrease protective/thermal cover as habitat availability deceases
Increase in physiological stress
Avoidance of roads
Temporary displacement and disturbance from activities during construction and operation
activities (e.g., noise, dust)
6
Increase in the probability of animal/vehicle collisions as vehicular traffic increases
In general, big game can be affected by anthropogenic disturbances such as urbanization, road
construction, off-highway vehicle (OHV) use, and energy development. Developments can create habitat
fragmentation and reduce available hiding and thermal cover as well as forage. Hiding and escape cover
at the edge of a forest opening is extremely important in forest types with a grass-forb understory with
few shrubs and decreases in importance as shrub cover increases inside an opening. Elk prefer clear-cut
areas with cover in the opening only where such cover does not inhibit the growth of forage. Interior
habitat or thermal cover is extremely important to moose for protection from inclement weather
conditions, security and protection from harassment and predation. Moose utilize lodgepole pine as a
thermal cover source during these months. Anthropogenic disturbances can also facilitate the spread of
exotic vegetation which in turn reduces quality and quantity of forage available to elk (Gelbard and
Belnap 2003). Big game can experience physiological stress in areas of high road density. Elk exposed to
increased road density and traffic has higher levels of physiological indicators, such as glucocorticoids
(Millspaugh et al. 2001). In addition to the increased stress hormone levels, the energetic costs of moving
away from disturbance associated with roads may be substantial (Cole et al. 1997).
The scientific literature highlights the significance of roads and road densities to big game. A summary of
peer-reviewed and UDWR impacts are discussed below. Big game response to roads vary greatly in
relation to the rates of vehicular traffic, the extent of forest escape cover near open roads, topography, and
the type of road, which also correlates with traffic rates (Lyon 1979, Witmer and deCalesta 1985, Johnson
et al. 2000, Rowland et al. 2000, Ager et al. 2003, Wisdom et al. 2005, Benkobi et al. 2004). Elk will
avoid areas near open roads (Lyon 1983). The frequency of elk occurrence and use increases at greater
distances from roads where motorized travel is allowed (Rowland et al. 2005).
In general, a road-effect zone exists, which is defined as an area beyond a physical boundary of the road,
can impact big game. Heavily roaded areas contain few patches of forest cover large enough to effectively
function as habitat for elk, especially during hunting areas seasons (Rowland et al. 2000, Ager et al.
2003). Wisdom et al. (2005b) observed deer more frequently selecting areas bordering forest roads with
higher levels of traffic (>4 vehicles for a 12 hour period) than roads with lower levels. This was true for
habitat selection during both diurnal and nocturnal hours, as well as between seasons.
A Shanley and Pyare (2011) study indicated that the road-effect zone for influencing moose behavior was
between 500 and 1,000 m (1,640 and 3,281 ft) for bull moose and over 1,000 m (3,281 ft) for cow moose.
Additionally, the probability of moose utilizing habitat within 500 m (1,640 ft) of a road decreased as
traffic levels increased. Additionally, the probability of moose utilizing habitat within 500 m (1,640 ft)
of a road decreased as traffic levels increased. Gaines et al. (2003) identified a correlation of road
avoidance for elk between road type based on traffic volume and mean distance ranging from estimated
zone of influence of 900 meters for low traffic (0-1 cars/12-hour period) to 900 m zone of influence for
high traffic (> 4 vehicles/12-hour period). It is anticipated that one vehicular trip will be made to the site
daily during operations.
Although forest roads can have negative effects on big game they also can provide some benefits. Forest
roads used by snowmobilers compact the snow making it passable for big game in lodgepole pine stands
in winter ranges near foraging areas as shelter in the winter months and security cover from predators.
Indirect impacts to big game can occur from noise. The acoustical environment in the vicinity of the
project area is typical of that associated with rural areas. Sound background levels would be expected
to range from nighttime levels of approximately 35 dBA to daytime levels of approximately 45-50
dBA. Actual noise levels within the project area would vary depending upon topography, proximity
to noise sources, and weather conditions, in particular wind velocity and direction. The typical noise
7
from the roads in the project area include grazing operations, light traffic on unpaved roads, and hunting
or other dispersed recreational activities. Sporadic road maintenance activities could increase local
noise levels. Hunting noise, including that associated with OHVs and gunfire, would be sporadically
noticed during the fall hunting seasons. Noise levels in the vicinity of the well pad would be
elevated during the four to eight weeks during which construction and drilling operations would
occur. Sound levels of 80 dBA or higher would be noted within 50 feet of the activities and
perception of sound could be heard up to several miles from the source of the activities,
depending on topography, vegetative buffering, and current local noise conditions. Following
completion of operations, the acoustical environment would continue to be modified by natural
sounds and those from introduced activities consistent with Forest management objectives.
The impacts to big game habitat from the proposed project in comparison to the hunt management area
are significantly small and shown below (Table 1).

in Utah, only 8.26 acres of habitat or <.00001% are within the proposed treatment units.
Of the acres of 376,640 acres of crucial summer range for mule deer and elk habitat on the North Slope
Summit in Utah, only 8.26 acres of habitat or <.00001% are within the proposed treatment units.
No roads are anticipated to be built for the project. Big game using the area may already be habituated to
the existing road structure. Approximately 1.5 miles of the existing roads are proposed to be improved for
access to and from the drill sight. These roads are anticipated to be used incrementally for the proposed
project only once per day. The maximum size for the drill pad proposed is 600’ X 600’. For protection to
big game and other animals, all reserve pits holding waste materials will be lined, and fenced stock tight
and pits containing oil or toxic liquids will be netted with a 2” mesh netting to avoid entrapment (see
Appendix F for details).
8
Because no new roads planned for the project, a low rate of additional use of the existing roads, a small
footprint of disturbance, lined, fenced and netted pits, and amount of available habitat adjacent to the
project area, the impacts to big games (mule deer, elk, moose, and pronghorn) are not anticipated to cause
detrimental effects to the big game populations in the project area.
Upland Game
Upland game that are known to occur, or could potentially occur, within the proposed project area include
blue grouse (Dendragapus obscurus), ruffed grouse (Bonasa umbellus), snowshoe hare (Lepus
americanus) and mountain cottontails (Sylvilagus nuttalli). Since snowshoe hares are also considered a
USFS Region 4 Management Indicator Species, its current environment within the proposed project area
and possible effects from the alternatives will be discussed in the Management Indicator Species section.
Blue Grouse Blue grouse are spread across the Wasatch-Cache but, they are rarely seen, and therefore, no great
concentrations exist on the North Slope. The UDWR classifies the blue grouse habitat within the Project
project area as year-long crucial and high value habitat. During the majority of the year, blue grouse
prefer habitats with open stands of conifer or aspen that have a brushy understory, but they will relocate
to mountain shrub, lower meadows, or open timber stands in the spring for the mating period. Mating
occurs in April, and nesting occurs during the months of May and June. During the spring/summer period,
their diet consists of green vegetation, seeds, buds, berries, and insects. Some males move back to higher
elevations immediately after breeding, while others relocate during the late summer/early fall, which is
the same time that the hens and young relocate. The bird’s diet during fall/winter at these higher
elevations primarily consists of needles and buds of fir trees (Rawley et al. 1996, Zwickel and Bendell
2005).
Ruffed Grouse Ruffed grouse numbers on the Forest are fairly low, but have been stable for several years. The UDWR
classifies the ruffed grouse habitat within the Project project area as year-long high value habitat. In
addition to utilizing thickets of mixed hardwood that includes aspen and conifers, the grouse will also use
brushy woodland areas adjacent to streams. The primary habitat during the breeding season is aspen, but
mountain riparian areas can be used as a secondary option (Parrish et al. 2002). Nesting generally occurs
during late April, May, or June. Important forage during these months until winter includes insects, fruits,
forbs, seeds, and plant tissues. During winter, the grouse’s diet will shift to almost exclusively deciduous
plant buds (Rawley et al. 1996). Ruffed grouse thrive best in young seral stage forests where understory
forbs and shrubs flourish.
Mountain Cottontail Mountain cottontails are common throughout the state of Utah in elevations over 6,000 ft (1,829 m). They
generally live in burrows near brush piles in sagebrush and mountain shrub communities. The rabbits are
active year round, and their diet consists of a wide variety of forbs, grasses, and shrubs (Rawley et al.
1996). The UDWR classifies mountain cotton-tail habitat is the Project project area as year-long high
value habitat.
Effects on Upland Game
Alternative 1
9
Under the No Action alternative there would be activities occurring with the project area. Under the No
Action alternative, there would be no direct effects to upland game species. Indirect effects to upland
game species may occur in the project area from impacts associated with large-scale natural disturbances
such as continued mountain pine beetle tree mortality and wildfire.
Alternative 2
Because of the small size of the project foot print and the amount of available habitat surrounding this
area, the project is not anticipated to cause population level affects to upland game.
Small Mammals Small mammals that occur, or are likely to occur, near the project area, according to the UDWR, include
the least chipmunk (Neotamias minimus), the Uinta chipmunk (Neotamias umbrinus), the Wyoming
ground squirrel (Spermophilus elegans), the northern pocket gopher (Thomomys talpoides), the long-
tailed weasel (Mustela frenata), and various shrews, mice, voles. A general summary of the dietary and
habitat requirements for these species is provided in the following:
Least chipmunks occur in various habitat types, which range from deserts to mountain forests,
and their diet primarily consists of seeds, fruits, nuts, and insects.
Uinta chipmunks are common inhabitants of mountainous areas of Utah and Wyoming. This
species is often found in coniferous forests, usually on the forest edge or in open areas. The diet
of the Uinta chipmunk generally consists of seeds, berries, and occasionally insects, eggs, and
carrion.
Wyoming ground squirrels prefer the loose soils of sagebrush, grassland, and mountain
meadow habitats. This squirrel is native to the extreme northeastern portion of Utah and southern
Wyoming. The Wyoming ground squirrel’s diet consists primarily of seeds, flowers, other types
of vegetation, insects, and meat.
Northern pocket gophers occupy a variety of habitat types, which includes grasslands, montane
riparian areas, and brushy habitats. Their diet primarily consists of plant roots, bulbs, stems, and
leaves.
Long-tailed weasels are habitat generalists that occur throughout Utah and Wyoming. Small
rodents, insects, birds, and other animals make up the diet of this small carnivore.
Shrews are primarily insectivores and are usually tied to moist habitats with higher amounts of
vegetative cover such as riparian areas and meadows.
Mice occupy a variety of habitat types throughout the state of Utah and Wyoming, and they have
a diverse diet which includes insects, seeds, and plant material.
Voles primarily use plant material for food and can occupy a variety of habitats, which include
upland sagebrush, riparian areas, and meadows.
Skunks prefer open areas, especially grasslands and meadows, and they have an omnivorous diet
that consists of small vertebrate animals, insects, plant matter, eggs, and carrion.
Snowshoe Hare The snowshoe hare is Management Indicator Species (MIS) of immature forest stands (pole/sapling)
(Forest Service 2003b:J4-J5). MIS are species selected because changes in their populations could
indicate the impacts of management actions on the overall quality of habitat for other species that utilize
the same habitat type. For the Wasatch-Cache National Forest, the northern goshawk (Accipiter gentilis),
10
snowshoe hare (Lepus americanus), and beaver (Castor canadensis) have been identified as “terrestrial
wildlife” MIS.
Hares are prey for a suite of forest predators including the federally listed Canada lynx (Lynx
Canadensis), American Marten, great grey owl, and northern goshawk. Hares are non-migratory but may
make seasonal movements to access winter and summer foraging areas (Ellsworth & Reynolds, 2006).
Snowshoe hares generally disperse less than 8 km and they will swim; therefore, small to medium sized
streams are generally not thought to be a barrier to dispersal (NatureServe, 2009).
Utah is the southern periphery of the range of the snowshoe hare (Ellsworth & Reynolds, 2006). Average
hare density in the intermountain west ranges from 0 to 2.70 hares/ha (Ellsworth & Reynolds, 2006). In
Utah and Colorado home ranges average 20 acres (8 hectares) (Dolbeer & Clark, 1975)). Snowshoe hare
habitat occurs within specific forest types that grow within a limited elevation gradient that contains a
high degree of natural habitat fragmentation and variability compared to northern latitudes. Because of
this fragmentation, changes to forest habitats could reduce survival, limit dispersal, isolate populations,
decrease connectivity and reduce recolonization (Ellsworth & Reynolds, 2006).
Snowshoe hares use thick dense woodlands with deep snow (Ellsworth & Reynolds, 2006). Several
authors have cited the importance of abundant understory to provide cover and forage for snowshoe hares
( (Belovsky, 1984), (Litvaitis, 1985), (Rohner & Krebs, 1996), (Wirsing, Steury, & Murray, 2002), (Berg,
2009)) Forest types that are used by snowshoe hares include aspen, aspen-conifer, Engleman spruce,
subalpine fir, limberpine, Douglas fir, white fir, grand fir, bristlecone pine, and cotton wood willow
habitats (Ellsworth & Reynolds, 2006). In the intermountain region, snowshoe hares are found in
lodgepole pine, multi-storied spruce-fir forests, Douglas fir, mixed conifer, aspen conifer, and riparian
willow.
In Utah the species is limited to coniferous forests, interspersed with thickets of aspen, willow, and alder
in the higher mountains (Utah Division of Wildlife Resources, 2004). On the UWC National Forest,
snowshoe hares are found in lodgepole pine, aspen-conifer, mixed conifer, spruce-fir, and Douglas Fir.
The snowshoe hare inhabit immature forest stands (pole/sapling) with a dense shrubby understory. There
is an estimate of 558,200 acres of snowshoe hare habitat within the Planning Area (aspen/conifer,
conifer/aspen, lodgepole pine, mixed conifer, Douglas fir, and spruce/fir forest types).
The snowshoe hares of the Wasatch-Cache National Forest Planning Area, has been divided into two
separate populations, the Wasatch/Bear River Range and the Uinta Mountain “North Slope Range”
because of a large habitat gap between mountain ranges that prevents genetic mixing of the populations.
The proposed project is within the Uinta Mountains population (Kamas portion of the Heber-Kamas
District and the Evanston- Mountain View District) of the Wasatch-Cache National Forest Planning Area.
Approximately 384,000 acres of the 558,000 acres of suitable habitat are within the Uinta Mountains.
In 2013 the number of pellets counted in the Uinta Mountains Population averaged 2.83 pellets/plot and
ranged from 0 – 18.4 pellets/plot. Calculations were made using Berg’s full equation buffer (Berg, 2009).
The 2013 snowshoe hare abundance is 0.35 hares/ha compared (0.29 hares/ha) in 2012. These data show
a statistically significant declining trend in pellets counted from 2004 through 2013 in the Uinta area (F=
11.20, p= 0.010). The downward trend in the Uinta Mountains population is likely due to a spike in the
population of snowshoe hares in 2004 and 2005. Comparatively, surveys in the past reported that hare
densities in Utah averaged between 0.34 to 0.68 hares/ha (depending on the method used (Bunnell, 2005))
11
and a spike of 2.70 hares/ha occurred in 1978 (Andersen, Macmahon, & Wolf, 1980). Since 2006 the
trend appears to be stable, to slightly declining and averages about 2.98 pellets per plot over 7 years.
Beaver-riparian The American beaver, which is the largest rodent in North America, was selected as a MIS for the
Wasatch-Cache National Forest because the rodent depends on riparian habitat which can be affected by
land use practices on the Forest and because the beaver is widely recognized as a keystone species, whose
dam-building behavior significantly affects ecosystem structure and function, as well as the habitat for
numerous plant and animal species (UWCNF 2012).
Beavers occur in permanent slow moving streams, ponds, small lakes, and reservoirs. Within these
habitats, their home range can vary between 20-45 acres, with nonfamily groups more often occupying
larger territories than family groups (UDWR 2010c). A family group makes up a beaver colony, which
generally consists of an adult pair, the young of the present year, and the young from the previous year.
On average, a colony consists of 5 or 6 beaver, with a typical range being 4 to 8 (UWCNF 2012).
No riparian habitat is within 1.25 miles of the project; therefore, impacts to beaver are not anticipated to
beaver and no further analysis is required.
Effects on Small Mammals
Alternative 1
Under the No Action alternative there would be activities occurring with the project area. Under the No
Action alternative, there would be no direct effects to small mammals. Indirect effects to upland game
species may occur in the project area from impacts associated with large-scale natural disturbances such
as continued mountain pine beetle tree mortality and wildfire.
Saplings will take over the open areas, regenerating the forest. Under the No Action alternative, this
succession will take a greater amount of time to occur.
Alternative 2
Because of the small size of the project foot print and the amount of available habitat surrounding this
area, the project is not anticipated to cause population level affects to small mammals including two MIS
(snowshoe hare and American beaver). Therefore, these effects are not expected to result in a change in
the population numbers or trend within the analysis area or result in a significant change in overall habitat
quality and population numbers or trend of snowshoe hares forest-wide

Canada Lynx The Canada lynx was proposed for listing as a threatened species under the Endangered
Species Act on July 8, 1998 (Federal Register Volume 63, No. 130). The final decision to list the
contiguous United States Distinct Population Segment (DPS), which included Utah, occurred on March
24, 2000 (Federal Register Volume 65, No. 58). The rationale for the listing was based on the conclusion
that the inadequacy of existing regulatory mechanisms was a major threat to the species.
In North America, Canada lynx range from the boreal forests of Alaska and Canada, to the subalpine
forests of the western United States and the boreal/hardwood forests of the eastern United States. Within
this distribution, lynx have large home ranges that generally vary between 12-83 miles2 (31-216 km2) and
vary based on habitat quality and prey availability (Koehler 1990, Aubry et al. 2000, Squires and Laurion
1999, Vashon et al. 2005). Characteristics of quality lynx habitat consists of mature forests at higher
elevations that have a dense, multi-layered understory. Along with lynx home range size, its survivorship,
13
productivity, and population dynamics are closely linked to the density of snowshoe hares, which is its
primary prey source.
Snowshoe hares are linked with disturbed and subclimax communities adjacent to thick cover (Giusti et
al. 1992, Koehler 1990, Poole et al. 1996, Wolff 1980). These types of areas are created mainly by burns
and clearcuts (Poole et al. 1996). The optimum habitat for snowshoe hares is second-growth forest stands
that are 15 to 40 years old and contain brushy understory and have a high density of saplings (Koehler
1990, Koehler et al. 1994). The successional changes in the disturbed forest stands that favor snowshoe
hares may also favor Canada lynxes (Koch 1996). For hunting snowshoe hares and dense climax forests
for denning and traveling, the Canada lynx prefer forest stands that are second-growth forests between 20
and 30 years old for hunting snowshoe hares (Fisher and Wilkinson 2005, Koehler 1990, Koehler and
Brittell 1990, Koehler et al. 1979, Parker et al. 1983, Thompson et al. 1989). For denning and traveling,
lynxes prefer dense climax forests, although the optimal age of forests for denning and traveling is not
currently available (Koehler and Brittell 1990, Murray et al. 1994, Ulev 2007).
Engelmann spruce, white fir (Abies concolor), subalpine fir, and lodgepole pine forests at elevations
ranging from 7,300 to 10,500 ft (2,250 - 3,250 m) are the primary vegetation types and elevations that
may contribute to lynx habitat in Utah. Stands only containing quaking aspen also occur throughout the
state, but snowshoe hares may use aspen stands much less than conifer stands (Wolfe et al. 1982). This is
probably because aspen stands lack dense over-story cover (Hodges 2000). Where they are intermixed
with spruce-fir and lodgepole pine stands, aspen stands would constitute secondary vegetation that may
contribute to lynx habitat (Ruediger et al. 2000).
Within the USFWS Recovery Outline for the Canada Lynx (USFWS, September 14, 2005), core areas,
provisional core areas, secondary areas, and peripheral areas were identified; none of these areas have
been identified to occur within or near the proposed project area. On November 9, 2005, the USFWS
proposed critical habitat for the Canada lynx within the United States; no critical habitat occurs within
Utah (50 CFR Part 17, Volume 70, No. 216).
The Uinta Mountains (both north and south slope) are the only place in Utah that has designated Lynx
Analysis Units (LAU), which represent an approximate home range of a lynx. They were established by a
working group comprised of biologists from the Ashley, Uinta, and Wasatch-Cache National Forests, US
Fish and Wildlife Service, BLM, and Utah Division of Wildlife Resources. Lynx habitat was then
classified as primary, secondary and non-habitat. The proposed project is located within LAU 33
(Appendix A).
The following is general lynx information for the Wasatch-Cache National Forest and the Evanston-Mt.
View Ranger District. On the Wasatch-Cache National Forest, there have been lynx sightings, as well as
surveys conducted to analyze the felids presence on the Forest. In 1999, 2000, and 2001 a national hair
snare survey was conducted to determine a presence/absence of lynx. Samples collected from the
Evanston Ranger District were sent in for analysis; results were negative for lynx hair. Winter track
surveys were conducted in conjunction with the Ashley National forest February thru March 2010,
February through April in 2011, and February through April 2012, in a coordinated effort to locate lynx
tracks on the Uintas and document their presence. Surveys conducted on the North Slope were
14
unsuccessful in finding any tracks documenting the presence of lynx. One of the 2012 lynx routes in
April, did survey the North Slope road from the west boundary of the project area, up the Suicide Park
Road (FS Road 074), and just outside the eastern boundary of the proposed project area along FS Road
072. Although tracks of other more common wildlife species were observed, no lynx tracks were seen
during the survey.
Additionally, the USFWS issued a Notice of Remanded Determination of Status for the contiguous
United States DPS of the Canada Lynx on July 3, 2003 (USDI 2003). The notice stated that “there are
only 10 verified records of lynx in Utah since 1916 (McKay 1991; McKelvey et al. 2000). Nearly all of
the reliable lynx reports are from the Uinta Mountain Range along the Wyoming border (McKay 1991).
Four of the records correlate to the cyclic highs of the 1960s and 1970s. Recent DNA results documented
the presence of a lynx in Utah (McKelvey in lit. 2003). There is no evidence of lynx reproduction in Utah.
We conclude that lynx that occur in the state as dispersers rather than residents, because most of the few
existing records correspond to cyclic population highs, there is no evidence of reproduction, and boreal
forest habitat in Utah is remote and far from source lynx populations.”
In recent years, there have been no confirmed lynx sightings in Utah. There is, however, documentation
that several radio-collared lynx from the Colorado reintroduction have at least passed through Utah and
spent time in the Hwy 150/Whitney Lake area of the Uinta Mountains in 2004 and 2006.
Maintaining connectivity with Canada and between mountain ranges is an important consideration for the
Northern Rocky Mountains Geographic Area (Ruediger et al. 2000). It is likely that the Northern Rocky
Mountains Geographic Area and the Southern Rocky Mountains Geographic Area of Colorado and
southern Wyoming are poorly connected. Shrub-steppe communities in central and southern Idaho,
Wyoming, southeast Montana, and eastern Oregon may provide connectivity between adjacent mountain
ranges. Along the Continental Divide, they may also provide an important north-south link between large
patches of lynx habitat. Table 3 displays the percentage and number of acres of primary and secondary
habitat that occurs on the Evanston-Mt. View Ranger District (USFS managed lands only).

Under the No Action alternative there would be activities occurring within the project area. Under the No
Action alternative, there would be no direct or indirect effects to Canada lynx.
Alternative 2 In the unlikely event of a lynx present, direct effects include the displacing of any animals and/or the
removal of primary and secondary habitat, which is high elevation mixed conifer forest. The proposed
action occurs in suitable, high elevation mixed conifer-dominated forest.

Analysis and Determination of Effect
Because there are no known lynx occupying the North Slope of the Uinta Mountains, the lynx habitat in
the vicinity is considered a transitory corridor, no increase in existing road base, and an extremely small
amount of habitat would be impacted by the proposed treatment, our determination s that the proposed
salvage project May Affect, but is not Likely to Adversely Affect this species.
Forest Service Intermountain Region Sensitive Species Sensitive species are those species identified by the Regional Forester for which population viability is a
concern, as evidenced by a significant current or predicted downward trend in numbers or density, or a
significant current or predicted downward trend in habitat capability that would reduce the species’
existing distribution. The complete list of mammalian and avian species designated as “sensitive” on the
Wasatch-Cache National Forest are displayed in Table 5. Detailed habitat requirements and general
distribution information for these species on the Wasatch-Cache National Forest are discussed in the
Revised Forest Plan (USDA Forest Service 2003).

Gray Wolf The gray wolf is a large dog-like mammal that is usually gray in color, but can vary from almost white to
black. The distribution of the gray wolf is circumpolar throughout the northern hemisphere. The native
range of the gray wolf is one of the most extensive of any terrestrial mammal species, with the historical
17
range encompassing all of Eurasia and North America (UDWR 2005). Present distribution is more
restricted to remote, undeveloped areas with sparse human populations (UDWR 2005). The gray wolf was
historically common in Utah, but extirpated from the state by early settlers. Recent reintroductions of the
gray wolf occurred in Idaho and Yellowstone National Park, and recent reports suggest that gray wolves
may move to Utah from surrounding states in the near future (UDWR 2005).
The species can live in various habitat types, but prefer areas with little human activity. Gray wolves
typically travel and hunt in packs covering large areas in search of prey. Prey species for the wolf are
typically larger animals, such as deer and elk, but they will also consume small mammals and carrion.
Analysis and Determination of Effect
The UDWR considers the gray wolf to be extirpated from the state of Utah. There are currently no known
packs or breeding pairs inhabiting Utah. In 2009, a radio collared wolf from the Yellowstone area traveled
through the North Slope and into Colorado unseen by anyone. The North Slope of the Uintas contains
suitable habitat for the gray wolf, but presently there are no known packs or breeding pairs on the
Evanston-Mt. View Ranger District (Pers. Comm. Dave Rich, UDWR wildlife biologist, and Jeff Short,
WGFD wildlife biologist) and wolves that have crossed into the District were just dispersing through.
Therefore, implementation of the Proposed Action May Impact individuals or habitat but will not likely
contribute to a trend towards federal listing or causes a loss of viability to the population or species.
Wolverine The wolverine is the largest terrestrial mustelid and is found in the tundra, taiga, and forest zones of North
America. Wolverines are typically associated with remote wilderness areas where minimal contact with
humans or developments occurs. As a scavenger it depends largely on mammal carrion provided from
kills by wolves and other predators. Wolverine will forage on snowshoe hare and other small mammals.
However, because of their size, carrion of ungulate species in the winter is also necessary for their
survival.
Refugia may be most important in providing availability and protection of reproductive denning habitat.
Life history requirements of the wolverine are tied to the presence and stability of ecosystems lacking
broad scale human influence. Dispersing wolverines in Idaho traveled over 124 miles following routes
across isolated subalpine habitat. They are able to move more than 20 miles in a day through rough terrain
and deep snow (Copeland 1996).
On February 4, 2013, the USFWS proposed to protect the North American wolverine as a threatened
species under the ESA. According to the USFWS, extensive climate modeling indicates that the
wolverine’s snowpack habitat will be greatly reduced and fragmented in the coming years due to climate
warming, thereby threatening the species with extinction. In a February 1, 2013 press release, the Service
stated that “the Service does not consider most activities occurring within the high elevation habitat of the
wolverine, including snowmobiling and backcountry skiing, and land management activities like timber
harvesting and infrastructure development, to constitute significant threats to the wolverine. As a result,
the Service has proposed a special rule under Section 4(d) of the ESA that, should the species be listed,
would allow these types of activities to continue.
18
On August 13, 2014, the USFWS withdrew the proposal to list the North American wolverine in the
contiguous United States as a threatened species under the ESA (USFWS 2014).
The Service stated the rationale for withdrawing the proposal in the August 13, 2014 Federal Register
Notice was “We have re-analyzed the effects of climate change on the wolverine under listing factor A
(the present or threatened destruction, modification, or curtailment of the species’ habitat or range). While
there is significant evidence that the climate within the larger range of the wolverine is changing,
affecting snow patterns and associated wolverine habitat, the specific response or sensitivity of
wolverines to these forecasted changes involves considerable uncertainty at this time.”
Recently, a trail camera picked up a wolverine about 20 miles from Evanston in Wyoming on April 10,
2014 (Uinta County Herald 2 May 2014) off National Forest lands. This animal stayed in the area for
about two weeks and was last seen on the April 27, 2014. On June 17th similar trail cameras were pulled
from the East Fork of the Blacks Fork just south of the guard station and the information analyzed. The
camera documented that a wolverine was in the area on the 18th of February, 2014. The individual was
not picked up after the 18th. The sighting on February 18, 2014 is approximately 5 miles from the nearest
treatment unit.
Analysis and Determination of Effect Wolverines are considered wanderers and travel great distances over their home range. In fact, estimates
generally suggest that female home ranges can encompass an area of 28 to 129 mi2 and males ranging
from 163 to 581 mi2 (Whitman et al. 1986, Copeland 1996, Landa et al. 1998, Persson et al. 2010).
Vegetative characteristics appear less important to wolverine than physiographic structure of the habitat.
Montane coniferous forests, suitable for winter foraging and summer kit rearing, may only be useful if
connected with subalpine cirque habitats required for natal denning, security areas, and summer foraging
(Wolverine Foundation, 2012). Natal den habitat on talus slopes may exist within the High Uintas
Wilderness, but salvage logging will not occur in these areas, nor will disturbance at lower elevations
occur during the winter months when this habitat is potentially utilized by wolverine. Prey base in the
summer months will include snowshoe hare and ground squirrels and these species can be affected by
salvage logging. Because wolverines have large home ranges, do not tolerate human disturbance, spend
majority of their time in high elevation wilderness areas, the proposed project is not expected to have
significant impact to wolverine or its habitat. Therefore implementations of the Proposed Action May
Impact individuals or habitat, but will not likely contribute to a trend towards federal listing or cause a
loss of viability to the population or species.
Boreal Owl The species breeds in North America from Canada to northeastern Minnesota, local breeding populations
can be found in Washington, Idaho, Wyoming, and Colorado. Forests ranging from pure deciduous to
mixed and pure coniferous composition characterize boreal owl habitat in North America. Suitable habitat
on the Evanston-Mt. View Ranger District would be old-growth Spruce-fir and high elevation mixed-
conifer stands. Boreal owls are cavity dependent and typically use old woodpecker nests. Southern red-
backed voles and other small mammals are important food sources for foraging boreal owls. Habitat
requirements for prey species vary from a well-developed understory to clear-cuts or natural openings.
Recently there was a confirmed nesting pair on the Uinta National Forest that is the first nesting pair
found in Utah. There has been one confirmed boreal owl on the Evanston-Mt. View Ranger District that
responded to broadcast surveys and it was located within a roadless portion of the West Bear Analysis
Area, in the vicinity of Whitney Reservoir approximately 22 miles west of the project area.
19
Analysis and Determination of Effect
Because of the very limited boreal owl occurrences and small size of the project area, the Proposed
Action May Impact individuals or habitat, but will not likely contribute to a trend towards federal listing
or cause a loss of viability to the population or species.
American Three-toed Woodpecker The three-toed woodpecker is found in sub-alpine conifer and lodgepole pine. It is a permanent resident
above 8,000 ft and dependent on live and dead trees for foraging and nesting. Trees with scaly bark
remaining on the tree are important to support their foraging technique. American three-toed woodpeckers
require trees infested with bark- and wood-boring insects for foraging. Greater than 75% of their diet
consists of wood-boring insects, mostly beetle larvae, but they also eat wood-boring Lepidoptera (mainly
moth) larvae, and occasionally fruit and sap at sapsucker pits (Leonard 2001). In the Wasatch NF BBS
(Sauer et al. 2008), this species was detected once in 2003 and twice in 2004.
Analysis and Determination of Effect
The pine beetle outbreak has created increased abundant opportunities for foraging and nesting in cavities
of dead trees. Because three-toed woodpeckers are dependent on dead conifers for both nesting and
foraging, and small project size, the implementation of the Proposed Action May Impact individuals or
habitat, but will not likely contribute to a trend towards federal listing or cause a loss of viability to the
population or species.
Great Gray Owl Great gray owls use mixed coniferous and hardwood forests usually bordering small openings or
meadows, foraging along edges of clearings.
In general, optimal habitat for great gray owls consists of semi-open areas, where small rodents are
abundant, and near dense coniferous forests for roosting and nesting. In the northern part of their range,
great gray owls are found in boreal forests. In Canada, studies have found that great gray owls breed in
forests near marshes, lakes, muskegs, wet meadows, and pastures. The forest types between 900m to
1200m elevation dominated by the following species (Duncan and Hayward 1994). Southwestern
Wyoming and Utah is considered wintering range from vagrants. The boreal owl is rare in Utah, where it
occurs in the Wasatch Mountains, the Bear River Range, and the Uinta Mountains (UDWR 2005).
The great gray owl's diet consists of almost entirely small rodents. About 90% of their diet consists of
pocket gophers and voles. Other small mammals taken by the owl include mice, squirrels, young rabbits,
hares, rats, moles, and weasels. Also taken are birds, usually small, although there are records of sharp-
shinned hawks, ducks, and grouse. Availability of nest sites and suitable foraging habitat are considered
the most important factors governing habitat use by breeding great gray owls.
Analysis and Determination of Effect
Great Gray Owl
Because of numerous nesting and foraging habitat on the North Slope as well as the status of the boreal
owl as a rare migrant, implementation of the Proposed Action May Impact individuals or habitat, but will
not likely contribute to a trend towards federal listing or cause a loss of viability to the population or
species.
20
Northern Goshawk The northern goshawk is a Forest Sensitive Species and also a MIS species as an indicator of mature
conifer forest. Goshawks nest in a wide variety of forest types including aspen, coniferous, and mixed
conifer forests in a wide variety of forest ages, structural conditions and successional stages. Northern
goshawk territories are found throughout the mixed conifer/aspen belt along the North Slope. Typically,
northern goshawks will nest in mature and old forests.
There are three main components of a goshawk’s home range (6,000 acres): nesting area, post fledging-
family area (PFA), and foraging area. On a landscape scale, the goshawk habitat on the North Slope has
been impacted by the destruction of 80-90%+ of the lodgepole pine forest type by the mountain beetle
pine throughout the goshawk’s home range. Nest areas contain one or more stands of large, old trees with
a dense canopy cover. Most goshawks have 2 to 4 alternate nest areas within their home range; alternate
nest areas are used in different years, but some nests may be used for decades.
The nesting trees (lodgepole pine) or the surrounding nests tree are typically dead and may eventually fall
over as evidenced by the number of down, dead trees throughout the North Slope. The goshawk PFA
surrounds the nest areas within a home range, totaling 420 acres and because of its size, includes a variety
of forest types and conditions. The foraging areas are approximately 5,400 acres in size. Goshawks are
more generalist predators and rely on a variety of mammals and birds as their prey base. Foraging
goshawks are found within a mosaic of forest types and hunt in many forest conditions. Goshawks in the
analysis area use mature lodgepole pine dominated stands and aspen/conifer stands. The goshawk preys
on large-to-medium sized birds and mammals, which it captures on the ground, in trees, or in the air.
Observations of foraging goshawks have shown that they hunt in many forest conditions. This
opportunism suggests that the choice of foraging habitat by goshawks may be as closely tied to prey
availability, as to habitat structure and composition. Specific habitat attributes used by these species
include snags, downed logs and woody debris, large trees, herbaceous and shrubby understories, and a
mixture of various forest vegetation structural stages.
It was concluded in the Conservation Strategy and Agreement for the Management of Northern Goshawk
Habitat in Utah that goshawk populations in Utah were viable. This conclusion was based on the findings
of Graham et al. (1999) that good quality habitat is well distributed and connected throughout the state.
The lack of evidence of a population decline on National Forest System lands since 1991, and conclusions
made by the U.S Fish and Wildlife Service (USFWS), after a review of scientific literature, aided in their
decision to not list the northern goshawk under the Endangered Species Act (USFWS 1998). The overall
trend of goshawk territories that have been occupied and active is stable (Figure 1, Figure 2).

There are 516,446 acres of northern goshawk habitat on the Wasatch-Cache portion of the Forest. The
habitat has been impacted on a landscape scale by a mountain pine beetle epidemic that has destroyed 80-
90%+ of the lodgepole pine forest type throughout the goshawk habitat. The beetle kill has deteriorated
the quality of the goshawk habitat making achieving desired conditions (Guideline 14) unattainable.
Guideline 14 identifies percentages that of landscape structures in different cover types that the forest is to
manage for. For the lodgepole pine cover type the balanced range is 10% grass/forb, 10%
seedling/sapling, 20% young forest, 20% mid aged forest, 20% mature forest and 20% old forest. These
percentages were initially set to provide large trees for goshawks in perpetuity (personal communication
Russell Graham, Research Forester 2011). The guidelines apply to living trees and major insect
infestations and tree mortality were not considered when the guideline was established. As mentioned
previously, the North Slope of the Uinta Mountains has experienced 80-90+% of lodgepole pine mortality
from the mountain pine beetle. In this situation the guideline percentages for mid-aged, mature and old
timber are unrealistic and unattainable.

Goshawks prefer stands of mature and over-mature trees for nesting and foraging, but can breed
successfully in forests where timber harvesting has occurred. Patch size in a timber stand has been
positively associated with the occupancy of an area. However, the effects of reducing the number and size
of mature trees on existing goshawk densities or productivity, is unknown (Graham et al. 1999).
The proposed project is within mapped goshawk habitat; however, there are no known goshawk territories
within 10-miles of the project area.
Analysis and Determination of Effect Because there are no known goshawk nests within the project vicinity, goshawks are generalists when it
comes to prey base, and a very small percent of goshawk habitat will be impacted by the proposed
project, the implementation of the action alternative is not expected to negatively impact the goshawks
ability to forage successfully in the proposed project area. Therefore, implementation of the proposed
action May Impact individuals or habitat, but will not likely contribute to a trend towards federal listing
or cause a loss of viability to the population or species.
Northern Goshawk Mitigation A seasonal nesting restriction from March 1st through August 1st will be in effect for any active territory
in the project area. Monitoring of northern goshawk territories on the North Slope have demonstrated that
goshawk nestlings fledged by the end of July and the adults are able to move the fledglings away from
any disturbance within the PFA. The District Biologist will be responsible on an annual basis for
determining if any of territories are active prior to commencing salvage harvest activities within nesting
areas.
Neo-tropical Migratory/Song Birds The Migratory Bird Treaty Act and Executive Order 13186 provide direction for the U.S. Forest Service
on the management of migratory birds.
Migratory Bird Treaty Act
Established a Federal prohibition, unless permitted by regulations, to "pursue, hunt, take, capture, kill,
attempt to take, capture or kill, possess, offer for sale, sell, offer to purchase, purchase, deliver for
shipment, ship, cause to be shipped, deliver for transportation, transport, cause to be transported, carry, or
cause to be carried by any means whatever, receive for shipment, transportation or carriage, or export, at
any time, or in any manner, any migratory bird, included in the terms of this Convention . . . for the
protection of migratory birds . . . or any part, nest, or egg of any such bird." (16 U.S.C. 703)
Executive Order 13186
Support the conservation intent of the migratory bird conventions by integrating bird conservation
principles, measures, and practices into agency activities and by avoiding or minimizing, to the extent
practicable, adverse impacts on migratory bird resources when conducting agency actions. Design
practices into agency plans and planning processes (natural resource, land management, and
environmental quality planning, including, but not limited to, forest and rangeland planning, coastal
management planning, watershed planning, etc.) as practicable and coordinate with other agencies and
nonfederal partners in planning efforts.
The Utah Partners in Flight (UPF) Utah Avian Conservation Strategy Ver. 2.0 (Parrish et al. 2002) ,
Wyoming Partners in Flight (WYPF) Wyoming Bird Conservation Plan Ver. 2.0 (Nicholoff 2003), and
the USFWS’s Birds of Conservation Concern (BCC) 2008 (USFWS 2008) were evaluated to determine
which species occur, or could potentially occur, within the area of the proposed project. The ecological
23
tenet underlying the process is that conservation actions focused on priority species will benefit other
avian species that utilize similar habitats.
UPF lists the project area occurring within the Utah Mountains and Wyoming Basin Physiographic
Regions. These regions comprise approximately 24% of the total land mass in Utah. The Utah Mountains
ecoregion occupies 23% of Utah’s land area and is made up primarily of the Wasatch and Uinta mountain
ranges and their associated valleys. Elevations range from 4,462 ft (1,360 m) in the Salt Lake Valley at
the edge of the ecoregion to 13,419 ft (4090 m) on King’s Peak. Most of Utah’s forested habitats occur
within this ecoregion. Lower elevations that have not been converted to urban or agriculture are primarily
shrub steppe, high desert shrub, and grasslands. The Wyoming Basin ecoregion covers only 1% of Utah’s
land mass. The majority of this ecoregion is located in Wyoming, where it covers nearly half of the state.
The elevations in the Wyoming Basin ecoregion are relatively high compared to the other ecoregions in
Utah. Elevations in this ecoregion range from 6,500 ft (1,970 m) in the valleys to 10,000 ft (3,030 m) at
the transition with the Utah Mountain ecoregion. The most common habitat type in the Wyoming Basin
ecoregion is high desert scrub, but shrubsteppe and grasslands are also sparsely scattered throughout the
ecoregion.

lands only)shows species listed on the USFWS’s BCC and UPF Priority Species for the Utah Mountains

Black Rosy-finch This species is an altitudinal migrant that nests above the tree line in the alpine tundra and winters in low
elevation valleys. The black rosy-finch feeds primarily on seeds of alpine plants, with some insects. The
black rosy-finch nests in cliffs or rock talus slopes. (Parrish et al. 2002). Wintering flocks of black rosy-
finches roost in large communal roosts in caves, mine shafts, on rafters of barns, and in clusters of old
cliff swallow nests. Black rosy-finches are among the least studied of North American birds because of
the inaccessibility of their general alpine habitat and nest sites generally located on cliffs. Because of their
high elevation use of alpine habitat, they were not detected on the Wasatch NF BBS.
Broad-tailed Hummingbird The broad-tailed hummingbird is essentially a mountain bird, and is common throughout Utah and in
most mountainous areas of Wyoming, although the state is on the northern edge of its range (Cerovski et
al. 2001). The broad-tailed humming bird has been described as the most common avian species in Utah
26
as it occurs in every part of the state. The broadtail breeds in riparian areas or adjacent habitat in both
lower valleys and higher elevations. The Broadtail appears in the lower valleys in April and later nests
near streams in the valleys and at higher elevations. The Broadtail is most conspicuous wherever it
occurs. The wings of the male make a loud shrill whirring or buzzing noise in flight which is
characteristic of summer in the mountain west. Breeding males defend their territory in U-shaped flight
displays which they perform in a pendulum fashion consisting of a series of power dives. The male will
fly vertically to a height of 9 or 12 m (30 or 40 ft) before turning to dive vertically over the nesting area.
The vertical climb is then repeated, and these breeding males perform these flights repeatedly during the
day over the nesting area (Parrish et al. 2002). Dorsal coloration of both males and females is iridescent
BBS data indicate a stable population in the Uinta Mountains but state point count data indicate a
downward trend throughout the state. From 1988 through 2007 the broad-tailed hummingbird was
detected on the Wasatch NF BBS survey in the area in 13 of the years and averaged 12 per year surveyed.
The high count was 19 in 1994 and the low count was 8 in 2003.
Broad-tailed humming birds are dependent on nectar-bearing flowering plants as they feed on floral
nectar. These hummingbirds will also feed on small insects, spiders, and occasionally tree sap from
woodpecker drillings. Insects are caught in the air as well as by gleaning from forage. The lack of nectar-
bearing plants in a home range will cause the females to abandon nesting (UCDC 2009).
Cassin’s Finch The Cassin’s finch breeds from Canada to the west-central United States. It inhabits montane coniferous
forests at high elevations. In winter months, some birds will migrate to lowlands, though most of the
breeding range remains occupied year round.
Nests are constructed on branches located high in conifer trees during the month of May. Occasionally the
nests are built near the trunk within a few feet from the top of the tree. In general, 4 to 5, but sometimes 3
or 6, eggs are laid and incubated by only the female. While incubating the eggs, the female receives food
from the male. The young are tended to by both parents and fledge from the nest at approximately 14 days
old.
The diet of this finch consists primarily of buds, fruit, and seeds. Occasionally the Cassin’s finch will
consume insects (Hahn 1996; Baicich and Harrison 1997).
Cordilleran Flycatcher The cordilleran flycatcher breeds in the western United States, Mexico, and a small portion of
southwestern Canada. During the winter, this flycatcher will migrate south particularly to Mexico. This
bird prefers forest, woodland, and riparian habitats.
The cordilleran flycatcher constructs nests on cliffs, steep banks, and sometimes around man-made
structures. In early summer, the female lays 3 to 4 eggs which are incubated by the female for 2 weeks.
Both parents tend to the chicks, which fledge from the nest at approximately 14 to 18 days old.
This flycatcher’s diet consists almost exclusively of insects. The insects are generally captured in flight,
but are also gleaned from foliage of trees and shrubs (Lowther 2000).
Golden Eagle Golden eagles are found in open habitats, which include tundra, shrublands, grasslands, woodland-
brushlands, and coniferous forests, from Alaska to northern Mexico. The bird feeds on small mammals,
snakes, birds, juvenile ungulates, and carrion. Nests are generally constructed on cliffs or in large trees.
27
On the Uinta Mountains, eggs are generally laid from late February to early March, and the incubation
period is generally between 43 and 45 days. Young are capable of flight between 60-77 days.
Elevations where nesting habitat may occur are high elevation (most likely 10,000 ft plus in elevation) so
nesting would be sporadic at best and associated with the mountain cliffs in the High Uinta Wilderness.
Home range varies from 20-33 square kilometers. Golden eagles have not been detected on the Wasatch
NF BBS.
Olive-sided Flycatcher The olive sided flycatcher breeds in Alaska, Canada, much of the United States, and part of northern
Mexico. The olive-sided flycatcher is migratory and travels into South America, Central America, and
southern Mexico for the winter months. During the breeding season, this bird prefers woodland and
forested areas, particularly areas where standing dead trees are present.
These birds nest in trees and produce a clutch of 3 eggs. The incubation is completed by only the female
for 2 weeks. The young will fledge from the nest around 2 to 3 weeks of age.
The olive-sided flycatcher is active mostly during the day. The bird will almost always perch on dead
branches in an exposed position near, or at the tops of the tallest trees in the stand. The diet of this
flycatcher is mainly made up of flying insects (Farrand 2009).
American Three-toed Woodpecker This species is also a Forest Service Sensitive species and is discussed under that section.
Williamson’s Sapsucker These birds feed on sap, mainly from conifers, but insects are their main food source during the nesting
season and they also eat berries outside of the breeding period. Sapsuckers are unique among
woodpeckers in drilling neat rows of tiny holes-or sapwells-in the trunks of trees. The sap provides food
for the sapsuckers and snags small insects that are eaten by hummingbirds and warblers (Bird Note,
2004). Williamson sapsuckers are primary cavity excavators nesting from 8,000 feet to timberline in
Utah. The major vegetation types used are sub-alpine conifer and aspen (UCDC, 2009). In the Wasatch
NF BBS this species has been detected 3 years between 1988 and 2007 and averaged .3 birds per year
surveyed. The high detection was 2 records in the 1988 survey and the low was zero detection in1990-94,
2001-03 and 2006-07.
Effects on Neo-tropical Migratory/Song Birds
Alternative 1 No impacts to neo-tropical migratory/song birds are anticipated from the No Action Alternative.
Alternative 2 It is not anticipated that implementation of Alternative 2 would have any significant negative impacts to
neotropical migratory bird species in the proposed project area. When an active nest is identified, a no
activity buffer zone, which has been set by the USFWS Utah Ecological Services Salt Lake City Field
Office, would be applied to the nesting area to avoid potential take. Salvage activities may resume once
the young have fledged the nest, or if it has been determined by a wildlife professional that the nest has
failed. If pre-disturbance surveys are not completed, salvage activities should not take place until after the
migratory bird breeding season is complete on July 31. With mitigation measures in place, it is
determined that Alternative 2 would not be detrimental to migratory bird species. For protection to
migratory birds all reserve pits holding waste materials will be lined and fenced stock tight. Pits
containing oil or toxic liquids will be netted with a 2” mesh netting to avoid entrapment. Netting pits to
28
exclude birds and other wildlife may include the following U.S. Fish and Wildlife Service design
recommendations for effective net installation (USFWS 2015).
Maintenance of fencing and netting would be performed to repair holes, re-stretch fencing and netting,
reset posts, etc. when corrective action is needed as a condition of the lease.
The intent for both the Migratory Bird Treaty Act and Executive Order 13186 are being met by reducing
the negative impacts and potential take of migratory bird species and by meeting guidelines and standards
established in the Forest Plan.
Cumulative Effects to Wildlife/Big Game Cumulative effects for wildlife in the project area include roads and recreation.
Roads/Recreation Cumulative impacts associated with recreation activities (e.g., hiking, camping, off-highway vehicle use,
hunting, etc.) are within the project area, constituting disturbance from noise and human presence during
these activities. This disturbance may displace wildlife into other areas. The displacement is not
anticipated to impact wildlife and big game significantly as no new roads planned as a result of
implementing the Proposed Action. There would not be an increase in the number of roads per square
mile and creating measurable long-term negative impacts to the big game species.
Cumulative Effects for Sensitive Species
Timber Past timber harvests was in 1995. Regeneration has created hiding cover for larger prey species. As the
regenerated trees thin out and increase in size, they become more suitable habitat for species such as the
boreal owl and northern goshawk. Since there are stands treated at various times since 1961, there is a
variety of age classes and suitable habitat for the various sensitive species and in conjunction with the
Proposed Action, past timber treatments will not result in long-term negative impacts to sensitive species.
Roads/Recreation Cumulative impacts associated with recreation activities (e.g., hiking, camping, off-highway vehicle use,
fishing, hunting, etc.) within the project area constitute disturbance from noise and human presence
during these activities. This disturbance may displace wildlife into other areas within the drainage. The
project is near adjacent roads, dispersed sites, campgrounds and the wilderness trail system. This will
leave large areas that are undisturbed and can provide sanctuary for wildlife species within the project
area.
Cumulative Effects for MIS
Timber Effects of past timber harvests vary between northern goshawks and snowshoe hares, the only MIS
species that may be impacted by the Proposed Action. Areas that have been treated create good foraging
grounds for goshawks during the 5-10 years in which there is an increase in the amount of forage for
small prey species. As the lodgepole saplings and aspen suckers begin to regenerate, the stands are very
thick and not suitable for goshawks. During the period in which the treated stands have thick regrowth,
the habitat becomes suitable for snowshoe hares. The stands can remain suitable snowshoe hare habitat
until about year 40 after the treatment. When the trees become too large, there is not enough forage and
cover for snowshoe hares during the winter months and the species moves to more suitable habitat. After
the trees have started thinning out, the habitat once again becomes suitable to goshawks. Goshawks will
begin to start nesting in these stands when the trees become large enough to hold nests.
29
Roads/Recreation See discussion for effects to sensitive species.
Livestock Grazing Browsing or grazing can have impacts on MIS by reducing the amount of forage and altering the structure
or composition of native plant communities. Grazing by livestock and wild ungulates may increase
competition with snowshoe hare for forage resources, particularly in riparian areas. Browsing or grazing
can also impact snowshoe hare habitat by reducing the amount of available winter browse.
Cattle are not likely to use the conifer habitats extensively because they do not produce more than 200 lbs
of forage per acre (USDA Forest Service 2007). Therefore effects from competitions with grazing occur
only within conifer/aspen and aspen/conifer habitats that are used both by snowshoe hares and grazed by
livestock. There is an estimate of 558,200 acres of snowshoe hare habitat within the Planning Area
(aspen/conifer, conifer/aspen, lodgepole pine, mixed conifer, Douglas fir, and spruce/fir forest types) of
these approximately 8.29 would be impacted by project activities .Therefore the effects are minimal to
snowshoe hare habitat within the proposed project area.

In Table 7 above, the “Acres Unsuitable” would not change to percentage of unsuitable acres. These
percentages are in compliance with the 2003 Revised Forest Plan.
Roads/Recreation
Roads and trails increase fragmentation of habitat across the landscape. Isolated island areas may become
unsuitable habitat and affect lynx by increasing forest edge and changing the amount of structural
30
complexity of the forest. There are no new roads planned as a result of implementing the Proposed Action
and no increase in the number of roads per square mile, therefore there would be no measurable negative
effects to lynx. Ruediger et al. (2000) recommends keeping road densities below two-miles/square mile.
Thomas (1979) recommends <1.5 miles of road/square mile for maintaining ~ 70 percent habitat
effectiveness within ¼- ½ mile of secondary roads. The existing open road densities for LAUs in the
analysis area are less than one mile/square mile and are within Ruediger et al’s 2000 recommended
guidelines for open road density to maintain habitat effectiveness adjacent to secondary roads.
Cumulative impacts associated with recreation activities (e.g., hiking, camping, off-highway vehicle use,
fishing, hunting, etc.) within the project area in LAUs 33, constitute disturbance from noise and human
presence during these activities. This disturbance may displace any lynx present within the proposed
project area into other areas within the LAUs. The majority of the recreational activity is from roads,
dispersed sites, campgrounds and the wilderness trail system. This will leave large areas that are
undisturbed and can provide sanctuary for lynx within the project area. Since a lot of the disturbance
occurs within specified areas, in most instances wildlife in and near these areas have habituated to the
level of noise and disturbance that currently exists. So within these areas of disturbance, recreational
activities combined with salvage logging activities should have minimal effects to lynx.
Cumulative Effects of Oil and Gas/ Seismic Exploration for all species
There are no plans for seismic activity. There are no active wells in the area.
All oil and gas which have been drilled in the area were drilled in the 90’s and have been plugged,
abandoned and reclaimed.
Forest Plan Direction Common to All Alternatives
Wasatch-Cache - Forest Plan Standards (S) and Guidelines (G)
Standards:

The project is within a small portion of LAU 33 (8.2 acres). There are no known issues associated with
seasonal movement by lynx in relation to the position the proposed project.
(G19) In Lynx Analysis Units with less than 10% denning habitat well-distributed, retain disturbance
areas smaller than 5 acres with tree mortality that could contribute to denning habitat. (USDA Forest
Service 2003a, Page4-43)
N/A. Denning habitat in LAU 33 is currently found in abundance and well distributed throughout the
analysis area. Forest Plan Guideline does not apply.
(G20) In Lynx Analysis Units maintain or restore (defer action) denning habitat in patches larger than
5 acres comprising at least 10% of habitat. (USDA Forest Service 2003a, Page4-43)
N/A. Denning habitat in LAUs 33 is currently found in abundance and well distributed throughout the
analysis area. Forest Plan Guideline does not apply.
(G21) For projects that may affect Forest Service Sensitive species, develop conservation measures and
strategies to maintain, improve and/or minimize impacts to species and their habitats. Short-term
deviations may be allowed as long as the action maintains or improves the habitat in the long term.
(USDA Forest Service 2003a, Page4-43)
There are no known FS Sensitive species that may be impacted by this project. Every effort has been
made to avoid and minimize impacts to the species and its habitat. Seasonal restriction of for nesting
birds will be implemented.
(G26) Protect key big game calving, fawning and lambing habitat and provide security in summer
concentration areas. (USDA Forest Service 2003a, Page4-43)
There are summer ranges found within the project area. Disturbance associated with project activities
will be minimal overall and there are large amounts of acres of available summer range throughout the
analysis area for big game to utilize as they migrate through.
(G29) Avoid disruptive management activities in elk calving areas, elk spring use areas, and bighorn
sheep lambing areas from May 1 through June 30. (USDA Forest Service 2003a, Page4-44)
Disturbance activities associated with salvage will be minimal overall and there are countless acres of
available calving and fawning habitat throughout the analysis area for big game to utilize as they migrate
through.
(G30) Avoid disruptive management activities (not public recreation activities) on deer, elk, mountain
goat and bighorn sheep winter range from November 15 through April 30. (USDA Forest Service
2003a, Page4-44)
Winter range does not exist for the above species mentioned.
