SUMMARY
The Spanish Fork Ranger District is proposing to implement actions identified in the
Soldier Creek Watershed Assessment that would enhance watershed conditions. Actions
proposed include: 1) Mechanical removal on approximately 3,790 acres of Pinyon-
Juniper (P-J) within the Upper Spanish Fork Canyon Management Area on the Uinta-
Wasatch-Cache National Forest. The mechanical treatments would include Bullhog
(Mastication) and lop and scatter treatments; 2) Aspen regeneration using prescribed fire
within a 5,800 acre area; 3) Connecting two existing ATV trails by adding 6.6 miles of
ATV Trail from the Highway 6 corridor up to Unicorn Ridge; 4) Changing the
maintenance level of the Old Sheep Creek Road (FS #691) from level 2 to level 1 and
install a gate on the road; 5) Restoring gullies that are currently eroding and producing
excess amounts of sediment in the Indian Creek area.
In addition to the proposed action, the Forest Service also evaluated the following
alternatives:
No Action- no treatment would be performed and the area would remain the same.
Based upon the effects of the alternatives, the responsible official will decide which
alternative will best accomplish the desired conditions for the project area while meeting
the Forest Plan Goals and Objectives.

CHAPTER 1 – PURPOSE AND NEED
Document Structure ______________________________
The Forest Service has prepared this Environmental Assessment in compliance with the
National Environmental Policy Act (NEPA) and other relevant Federal and State laws
and regulations. This Environmental Assessment discloses the direct, indirect, and
cumulative environmental impacts that would result from the proposed action and
alternatives. The document is organized into four parts:
Introduction: The section includes information on the history of the project proposal,
the purpose of and need for the project, and the agency’s proposal for achieving that
purpose and need. This section also details how the Forest Service informed the
public of the proposal and how the public responded.
Comparison of Alternatives, including the Proposed Action: This section provides a
more detailed description of the agency’s proposed action as well as alternative
methods for achieving the stated purpose. These alternatives were developed based on
significant issues raised by the public and other agencies. This discussion also
includes possible mitigation measures. Finally, this section provides a summary table
of the environmental consequences associated with each alternative.
Environmental Consequences: This section describes the environmental effects of
implementing the proposed action and other alternatives. This analysis is organized
by issues to be analyzed in detail. Within each section, the affected environment is
described first, followed by the effects of the No Action Alternative that provides a
baseline for evaluation and comparison of the other alternatives that follow.
Agencies and Persons Consulted: This section provides a list of preparers and
agencies consulted during the development of the environmental assessment.
Appendices: The appendices provide more detailed information to support the
analyses presented in the environmental assessment.
PLANNING RECORD
Additional documentation, including more detailed analyses of project-area resources, may
be found in the project planning record located at the Spanish Fork Ranger District Office
in Spanish Fork, Utah. It contains planning records, Interdisciplinary Team (IDT) notes,
specialist reports, and maps.
Background _____________________________________
There has been a steady increase in the density of Pinyon-Juniper (P-J) trees throughout
the Upper Spanish Fork Canyon Management Area. This increase in tree density is
allowing the P-J to take over the sagebrush/grass areas. This infestation is causing
problems with riparian areas and wildlife habitat (sage grouse, mule deer), due to
decreased herbaceous vegetation and desirable shrubs. It is also increasing the fuel
loading of the area providing for the possibility of more intense and severe wildfire
effects on the ecosystem including loss of important wildlife habitat. There has been a
decrease in the number of young healthy Aspen stands as conifer encroachment has
Environmental Assessment Sheep Creek Project
3
increased in the area. There has been a desire to relocate roads and trails (e.g. FS Rd #
691) out of riparian areas to improve riparian and watershed conditions. The ATV trail
that would connect the top and bottom of Sheep Creek Canyon would meet that need
along with addressing erosion concerns and location of FS road #691. There are erosion
concerns in these canyons related to these conditions.
Purpose and Need for Action ______________________
The purpose of this project is to improve the conditions in the Upper Soldier Creek
Watershed, by improving wildlife habitat, improving recreational opportunities and
modifying fuels; through a reduction of juniper density, regeneration of aspen stands,
gully restoration, creation of a new forest system OHV trail and changing the
maintenance level of an existing forest system road within a riparian area.
The need for this project comes from the findings of the recently completed Soldier
Creek Watershed Assessment. The juniper in this area is invading from the steep, rocky
slopes, where it is most commonly found, into the sage steppe community, where
naturally occurring fire usually would have kept it out. This change from a sage steppe
community to a juniper thicket would increase the intensity/severity of a wildfire should
an unplanned ignition occur. This increased severity could lead to a loss of crucial mule
deer winter/spring range in the area. The encroachment of juniper is limiting the
diversity of plant and animal species within the area. The invasion of junipers excludes
other plant species by limiting resources (water, light and nutrients) available to the
understory vegetation. As other plant species are excluded, ground cover is decreased
and the potential for soil erosion is increased. The loss of plant species diversity limits
forage availability for animal species. Thick continuous canopy discourages use by many
wildlife species because of the lack of herbaceous understory forage production. Wildlife
species benefit from openings in the shrub/tree canopy and from a diversity of age and
structural classes of shrubs/trees. Mule deer are browsers that primarily eat shrubs and
other woody materials. Juniper out competes the understory vegetation and reduces the
amount of browse available to deer. Lack of understory vegetation can lead to increased
soil loss through soil erosion. As soil erosion is increased, stream sedimentation increases
and water quality decreases. The encroachment of juniper and the loss of ground cover
can also increase the potential for the spread of noxious weeds. Parts of the proposed
project area contain three of the Utah Partners for Conservation and Development
(UPCD) conservation focus areas (rangeland, riparian and forest).
Fuels Management
Fuels have been accumulating over the years due to human cultural practices and
changing climatic conditions. Spanish Fork Canyon, Sheep Creek and Soldiers Summit,
all nearby communities, are listed as some of Utah’s Communities at Risk (Utah Division
of Fire, Forestry and State Lands, 2009). The 2006 Northern Utah Regional Wildfire
Protection Plan (RWPP) designates this area as a moderate - high risk area for wildfire
(Utah Division of Fire, Forestry and State Lands, 2006). Hazardous fuels reduction
Sheep Creek Project Environmental Assessment
Page 4
treatments would help minimize the risks to private land, structures, and natural resources
(i.e. watersheds), from potential wildland fires.
Wildlife Habitat Management
Part of this area is critical mule deer winter range. As housing development on private
land continues to increase, available mule deer winter range decreases and it becomes
more critical to have properly functioning big game winter range on National Forest
System lands. Winters with abundant snowfall also increase the need for proper
functioning winter range.
Road/Travel Management
The Old Sheep Creek Road (FS # 691) is a road that is positioned adjacent to Sheep
Creek that provides limited public access to NF Lands for approximately 2 miles and then
terminates or ends. This road is causing increases in the sediment yield into sheep creek
and then on into Soldier Creek because of its location with respect to the stream channel.
Soldier Creek is currently listed as 303d impaired water for sediment and total
phosphorus. This road is currently open to high clearance vehicles only and is not a safe
road for the general public to travel.
The proposed Sheep Creek OHV Trail is needed to provide a designated system trail for
better public access to NF lands and connections to other system trails while being
located outside of riparian areas and away from stream channels. Currently there is no
trail that allows ATV users to legally access the ATV trail system at the upper elevations
in the canyon from the highway 6 corridor. So ATV users are creating their own non-
system trails, causing impacts to wildlife habitat and promoting soil erosion. Having a
properly designed and legally designated system trail would curb the use of ATV’s on
non-system trails, thus improving overall watershed conditions.
Aspen Management
Many of the Aspen stands in the project area are in an old, decadent age class. Other
stands are being impacted by conifer encroachment. There is a need to have a variety of
age class aspen stands and regeneration of aspen to keep the aspen stands healthy.
Healthy aspen stands are important wildlife habitat.
Current Management Direction
This project is located in the Upper Spanish Fork Canyon Management Area. Small
portions of Strawberry Ridge, Diamond Fork, and Chipman Creek Roadless Areas and all
of the Tie Fork Roadless Area fall within the project area. The management prescriptions
for this area are: 3.1 Aquatic, Terrestrial, and Hydrologic Resources; 3.3 Aquatic and
Terrestrial Habitat; 4.4 Dispersed Recreation, 5.2 Forest Ecosystems-Vegetation
Management, 6.1 Non-Forested Ecosystems and 8.2 Utility Corridor/Communication
Sites. The three Recreation Opportunity Spectrum designations for the area are: Roaded
Modified, Semi-Primitive Motorized and Roaded Natural.
Environmental Assessment Sheep Creek Project

The Desired Future Conditions (DFC) (as found in the 2003 Land and Resource
Management Plan Uinta National Forest) for the area include:
1) Habitat for the endangered clay phacelia, as identified by Harper and Armstrong
(1992), is managed to maintain its integrity. A habitat management strategy for
clay phacelia is in place.
2) Summer motorized use is permitted on designated routes throughout the
management area. Motorized loop trails are developed to enable users to travel
between this management area and the Diamond Fork Management Area.
Heavily-used dispersed recreation sites have been hardened and vegetation and
soil protection has been established. The Sheep Creek Road is managed as an
important forest access route. Dispersed recreation opportunities are available
throughout the management area; however, active management is focused along
the road corridors. The Great Western Trail is managed to maintain its
designation as a National Millennium Trail.
3) Livestock grazing activities continue to be permitted on the allotments within this
management area.
4) Fuels reduction treatments are focused along the utility corridors along U.S.
Highway 6.
5) When opportunities that are in the public interest for land transaction become
available, the Forest Service works towards acquisition to block up National
Forest System lands and protect public access. Utility corridors run the length of
the management area on the southern side. An electronic site serviced by an
underground cable is located on Teat Mountain. A utility corridor for the Deseret
Generating and Transmission line crosses the midpoint of the management area.
Vegetation management in these locations is limited to that consistent with the
installation and maintenance of the facility. Incidental dispersed recreation use
may occur in these areas.
6) The Indian Creek Road (#042) is reconstructed providing continuous passenger
car road access from State Highway 6 to Strawberry Reservoir.
Forest-wide Goals and sub-goals applicable to this project are found in Appendix A.
These goals and sub-goals were taken from Chapter 2 of the 2003 Uinta Forest Plan.

Proposed Action _________________________________
The USFS is proposing to improve the conditions in the Upper Soldier Creek Watershed,
by improving wildlife habitat, improving recreational opportunities and modifying fuels;
through a reduction of juniper density, regeneration of aspen stands, gully restoration,
creation of a new forest system OHV trail and changing the maintenance level of an
existing forest system road within a riparian area. The proposed action is discussed in
detail in Chapter 2.
Decision Framework ______________________________
Given the purpose and need, the deciding official reviews the proposed action and the
other alternatives in order to make the following decisions:
Whether to implement the proposed action as is or modify;
Whether to take no action.
Public Involvement _______________________________
The proposal was listed in the Quarterly Schedule of Proposed Actions since April 2012.
The proposal was provided to the public and other agencies for comment during
scoping/request for comment with a letter sent on May 11, 2012. In addition, as part of
the public involvement process, the agency published a legal notice in the Provo Daily
Herald on May 15, 2012. Two responses were received, one from a grazing permittee,
and the other from a utility company. Using the comments received from the public and
from within, the interdisciplinary team developed a list of issues to address.
Issues __________________________________________
The Forest Service separated the issues into two groups: issues to be analyzed in depth,
and issues not to be analyzed in depth. Issues to be analyzed in depth were defined as
those directly or indirectly caused by implementing the proposed action. Issues not to be
analyzed in depth were identified as those: 1) outside the scope of the proposed action; 2)
already decided by law, regulation, Forest Plan, or other higher level decision; 3)
irrelevant to the decision to be made; or 4) conjectural and not supported by scientific or
factual evidence. The Council on Environmental Quality (CEQ) NEPA regulations
require this delineation (40 CFR 1501.7) “…identify and eliminate from detailed study
the issues which are not significant or which have been covered by prior environmental
review …” A list of issues not analyzed in depth and reasons regarding their
categorization as such may be found following the issues to be analyzed in detail.
The following issues were identified to be analyzed in depth pursuant to 40 CFR 1501.7
based upon internal and public scoping:
Issue #1 Prescribed fire and Power Poles: May impact power poles
Environmental Assessment Sheep Creek Project
7
Indicator: Burned power poles.
Issue #2 Air Quality: The proposed action may impact Air Quality.
Indicator: PM2.5 emissions
Issues considered, but eliminated from detailed analysis
Cultural Resources/Heritage: No Historic Properties would be affected by this
proposed action, because of the mitigation measures that are in place (Flanigan, 2012).
Fisheries/Aquatics: The proposed action “may impact individuals but is not likely to
cause a trend towards Federal listing or a loss of viability for the populations or
species” for Bonneville cutthroat trout, southern leatherside chub, Columbia spotted frog,
and boreal toads. Overall the proposed action should reduce sediment delivery to the
riparian areas in the project area, which should lead to improved habitat conditions for all
of these Forest sensitive species (Whitton, 2012).
Recreation: The vegetation treatment portion of this project would have no long term
negative effects to recreation. The trail addition part of this project would enhance
recreation access by connecting three separate trail systems (Resare, 2012).
Migratory Birds: Although this project may result in an unintentional take if work is
accomplished during the breeding season, this project complies with the Fish and
Wildlife Service Director’s Order #131 related to the applicability of the Migratory Bird
Treaty Act to federal agencies and requirements for permits for “take”. In addition, this
project complies with Executive Order 13186 because the analysis meets agency
obligations as defined under the December 8, 2008 Memorandum of Understanding
between the Forest Service and Fish and Wildlife Service designed to complement
Executive Order 13186. If new requirements or direction result from subsequent
interagency memorandums of understanding pursuant to Executive Order 13186, this
project will be evaluated to ensure it is consistent (Hartman, 2012).
Hydrology: This proposed project would reduce natural fuel build up while improving
native plant diversity, age class and vigor. These changes in vegetation composition and
fuel loads would improve the overall health of the watershed and reduce the potential for
a large-scale, high intensity wildfire that would have negative impacts to water resources
and water quality (Goodman, 2012).
Threatened, Endangered and Sensitive Species Plants: The only TES plant found
within the project area was Angelica Wheeleri, listed on the Forest Service Sensitive
Plants List, this project May Impact Individuals or their Habitat, but will not likely
contribute to a trend towards federal listing or loss of population viability. The project
would have no effect to other TES Plants (Leinbach, 2012).
Threatened, Endangered and Sensitive Species Wildlife: There are no Threatened or
Endangered species in the project area, so there will be No Impact to Threatened or
Sheep Creek Project Environmental Assessment
Page 8
Endangered Species. There are four Sensitive Species that may occur in the Project
Area: Bald Eagle, Flammulated Owl, Northern Goshawk and Northern Three-Toed
Woodpecker. The project is not likely to move them towards federal listing (Hartman,
2012).
Roadless/Wilderness Areas: There are 5 roadless areas that fall within the project
boundary. There will be no significant effects on unique features because there are none.
The project should not affect the areas suitability for wilderness designation (Stavast,
2012).
Soils: The effects to soils will be positive, as long as heavy machinery is not operated
when the soils are in a wet /saturated condition and as long as the prescribed fire is a low-
moderate severity underburn. Old Sheep Creek Road (FS # 691) follows Sheep Creek.
This road, because of its location with respect to the stream channel, is causing increases
in the sediment yield into Sheep Creek and then on into Soldier Creek. By closing this
road for use and gating it, erosion and sedimentation into Sheep Creek should decrease.
By creating a loop and building the trail to a standard; erosion potential is lessened
(Weems, 2012).
Range: It is recommended that junipers cut in the riparian area are left onsite to deter
cattle grazing in the riparian area. The area will need to be rested for two growing
seasons following prescribed fire. The ATV Trail needs to be located outside of the
gathering pasture and as far from the fence as possible to avoid conflicts with cattle
(Bragonje, 2012).
Fuels: Fuel loading will be modified and fuel models will change to reduce the effects
should a wildfire occur in the area (Stavast and Brown, 2012).
Climate Change: Climate change trends identified within the Sheep Creek Project
include; increased fuel build-up and risk of uncharacteristically severe and widespread
forest fire in traditionally fire-prone forest, woodland, and shrub types, longer fire
seasons; atypical fire seasons (e.g., winter, early spring), and higher-elevation insect and
disease and wildfire events (large fires already moving into true fir and subalpine forests).
The Sheep Creek project address effects to climate change by reversing the trends listed
above and creating conditions that would lead to; reduced fuel build-up and reduced risk
of uncharacteristically severe and widespread forest fire in traditionally fire prone forest,
woodland and shrub types, reduced potential for frequent fires and allowance for fires of
lighter intensity, reduced stresses caused by overcrowded and dense stands of trees that
lead to stressors (e.g. insect & diseases, high severity fire), and maintenance,
enhancement or promotion of native, diverse vegetative communities across the
landscape.

CHAPTER 2 ALTERNATIVES, INCLUDING THE PROPOSED ACTION
This chapter describes and compares the alternatives considered for the Sheep Creek
Project. It includes a description and map of each alternative considered. This section
also presents the alternatives in comparative form, sharply defining the differences
between each alternative and providing a clear basis for choice among options by the
decision maker and the public.
Alternatives _____________________________________
Alternative 1
No Action
Under the No Action alternative, current management plans would continue to guide
management of the project area. No activities would be implemented to accomplish
project goals.
Alternative 2
The Proposed Action
The USFS proposed to (Figure 1):
1) Reduce the density of junipers within 3,575 acres of the project area through
the use of a bullhog/masticator.
2) Change the maintenance level of the Old Sheep Creek Road (FS #691) from
level 2 to level 1 and install a gate on the road.
3) Connect two existing ATV trails by adding 6.6 miles of ATV Trail from the
Highway 6 corridor up to Unicorn Ridge. Approximately 5.5 miles of the trail
will be on abandoned road beds with the last 1.1 mile being new construction.
The designated use period for this trail is proposed as April 15 to November
15.
4) Remove Junipers from the riparian areas using chainsaws (approximately 215
acres).
5) Use prescribed fire to regenerate aspen and remove conifers within an
approximately 5,800 acres area.
6) Restore gullies that are currently eroding and producing excess amounts of
sediment in the Indian Creek area.

Figure 1. Sheep Creek Project Proposed Action Map Alternative 2.
Project Implementation Design Features
In response to public comments on the proposal, mitigation measures were developed by
the IDT to ease some of the potential impacts the various alternatives may cause. The
mitigation measures may be applied to the action alternative.
All sites eligible to the National Register within the mechanical mastication
(bullhog) and road rehabilitation units will be protected using a 150 foot buffer
and treated using lop and scatter techniques in place of mastication techniques.
Roads scheduled for rehabilitation that are believed to be contributing features to
eligible mining sites should be treated with non-ground disturbing techniques
only.
Mitigation will be implemented to protect the eligible historic structures prior to
the implementation of fire treatment. This may consist of a buffer, fire break,
wrapping structures, etc.
No bullhog/masticator use will occur during saturated soil conditions.
No mechanical equipment operation within 100 feet of perennial drainages. Trees
immediately adjacent to stream channel will not be masticated.
Environmental Assessment Sheep Creek Project

Livestock grazing areas that are treated with prescribed fire will be rested for a
minimum of two growing seasons after they area burned.
Alternatives Considered but Eliminated From Detailed Analysis
No other alternatives were considered.
Comparison of Alternatives ________________________
This section provides a summary of the effects of implementing each alternative.
Information in the table is focused on activities and effects where different levels of
effects or outputs can be distinguished quantitatively or qualitatively among alternatives.
Table 1. Comparison of Alternatives for the Sheep Creek Project
Key Issue to be Addressed in
Detail Alternative 1 Alternative 2
Impacts to Power Poles No effect to power poles. There is a slight possibility of
power poles getting burned,
There is very little
vegetation/fuels around the
power poles which greatly
reduces the risk, there is a road
that a fire would have to cross
to reach the power poles, which
would provide easy access for
fire crews to monitor the poles.
The ignitions would be done in
or near the aspen/conifer stands
which are quite a ways from the
power poles.
Air Quality
None-there would not be a Rx
fire and therefore no smoke
emissions. However, if a
wildfire were to occur the
amount of smoke emissions
would exceed that of the Rx
fire.
Air quality standards would not
be exceeded for PM2.5. The
maximum concentration of
PM2.5 would be 34 ug/m3,
which does not exceed the EPA
standard of 35 ug/m3.

CHAPTER 3 AFFECTED ENVIRONMENT AND ENVIRONMENTAL CONSEQUENCES
This section summarizes the physical, biological, social and economic environments of
the affected project area and the potential changes to those environments due to
implementation of the alternatives. It also presents the scientific and analytical basis for
comparison of alternatives presented in the chart above.
Affected Environment
Wildlife:
The project area contains identified corridors for the Canada lynx, a threatened species.
No endangered species or their habitats are found within the Project Area. While the
Forest Plan has identified lynx corridors within the Upper Spanish Fork Management
Unit, it is highly unlikely that they would be found in the Sheep Creek and Soldier Creek
watersheds. The vegetation cover in that area is primarily pinyon/juniper and sagebrush
(USDA 2003). The project also contains habitat for four sensitive species; bald eagle,
flammulated owl, northern goshawk, and the northern three-toed woodpecker. Two of
these species, goshawk and bald eagle, are found within or adjacent to the project area.
The three management indicator species, northern goshawk, northern three-toed
woodpecker and beaver, are found within or adjacent to the project area.
The following bird species are considered either FWS Birds of Conservation Concern or
Partners in Flight priority species and have been found in surveys within or near the
project area over the last ten years; golden eagle, flammulated owl, broad-tailed
hummingbird, Virginia’s warbler, black-throated gray warbler, and Brewer’s sparrow.
The project area is home to mule deer, elk and occasionally moose.
Hydrology:
The project area is within the following HUCs: Lower Soldier Creek 160202020107
(36,987 acres), Middle Soldier Creek 160202020105 (11,018 acres), Tie Fork
160202020103 (12,500 acres), and Upper Soldier Creek 160202020102 (25,115 acres).
The Forest Service 2011 Watershed Condition Framework rated three of the watersheds
as Functioning at Risk: Lower Soldier Creek, Middle Soldier Creek and Tie Fork. The
fourth, Upper Soldier Creek was rated as Functioning Properly. The 2012 Soldier Creek
Watershed Assessment identified projects that would move the watershed toward desired
conditions. These projects include juniper treatments, road improvements, OHV
connector trail, and closure of unauthorized OHV trails. Field visits to the project area
were conducted on May 2 and June 21 2012.
Soils:
Information about the type of soils in the Sheep Creek project area can be found in the
Hobble Creek, Diamond Fork, White River Soil Survey (1976). Soil characteristics are
Environmental Assessment Sheep Creek Project
13
described in a very general sense due to the large mapping scale and the wide variety of
site characteristics (see Soil Resource Report, Table 1, pg 4). Approximately 218 acres
within the soil analysis area are located on low or moderate erosion hazard if disturbed.
The remaining acres are located on high to very high surface erosion hazard landtypes.
An inter-agency team completed an inventory of stream bank erosion for Soldier Creek
and its tributaries which included Sheep Creek and Tie Fork drainages. In Sheep Creek
drainage bank erosion was estimated to contribute to sediment exceeding 2,000
tons/mile/year to Sheep Creek (Forest Service, 2012). The erosion rate for the main
channel of Sheep Creek was estimated at 268 tons/mile, Sheep Creek tributaries
estimated at 2,079 tons/mile, and Tie Fork estimated at 1,747 tons/mile.
Ground cover and organic matter are indicators that relate to the long-term productivity
of the soil resource by providing cover and nutrient supplies. Ground cover is cover that
will dissipate the erosive forces of water and wind and consists of vegetation canopy,
vegetation surface litter, and rocks >3/4 inch. Ground cover estimates ranged from 90 to
100% within the project area. Organic matter is the vegetation surface litter and acts as a
reservoir for several nutrients and is the source of most available phosphorous, sulfur,
and nitrogen. Organic matter estimates range from 90 to 100%. Measured duff layers in
Aspen stands along Willow Creek Ridge ranged from about ½ inch to 4 inches.
The Old Sheep Creek Road (FS # 691) is a road that is positioned adjacent to Sheep
Creek that provides limited public access to NF Lands for approximately 2 miles and then
terminates or ends. This road is causing increases in the sediment yield into sheep creek
and then on into Soldier Creek because of its location with respect to the stream channel.
Soldier Creek is currently listed as 303d impaired water for sediment and total
phosphorus.
Cultural/Heritage Resources
Archaeological materials associated with the Native American occupation of the Wasatch
Mountains consist of surface and buried deposits indicative of Native American cultures,
in open air sites and rock shelter contexts. The Project area falls within the Soldier creek
watershed and the original 1864 boundary of the Uintah and Ourary Ute Indian
Reservation and was a known area of importance to the tribe. In 1905 and 1909, the
boundaries of the reservation were modified and the Strawberry Valley later became a
mix of private, State and Federal land. Historic resources within the project area are most
commonly associated with agricultural activities, including water retention and
conveyance systems. Other historic resources in the area relate to numerous episodes of
historic U.S. Army training with the greater Strawberry Valley, and the Soldier Creek
Watershed, hence its name.
Range
The project area contains portions of 4 grazing allotments, three sheep and one cattle. Of
the acres within the project area, approximately 67% are grazed and 33% are not grazed
Sheep Creek Project Environmental Assessment
Page 14
by sheep or cattle. The range status is expressed in terms of condition rather than
ecological status because it has been seeded. The range status is considered to be in good
condition. There is an abundance of plants both native and non-native and there is
sufficient ground cover for the project area.
Fuels
The majority of the vegetation conditions within the mastication units can be represented
by fuel models SH2 (moderate load dry climate shrub) and SH5 (high load dry climate
shrub) (Scott and Burgan 2005). Fuel model SH2 best represents sagebrush areas with
low tree densities. Fuel model SH5 represents areas of high tree and shrub densities. The
majority of the vegetation conditions within the aspen-conifer stands can be represented
by the Scott and Burgan (2005) fuel models TU1 (low load dry climate timber-grass-
shrub), TU5 (very high load, dry climate timber-shrub), and TL3 (moderate load conifer
litter). Fuels and vegetative conditions in this area represent a FRCC 2, where there is a
moderate departure from reference conditions. Due to the continuous, dense canopy of
juniper and gambel oak over much of the project area, wildfire is more likely to be a
relatively severe crown fire. This has implications for firefighter and Forest visitor safety,
and for the ability of the plant community to recover post-fire. Higher severity fires leave
little ground cover, causing increased erosion, and making the area more susceptible to
cheatgrass invasion. Areas dominated by cheatgrass have a high flashy fuel loading and
are subject to fast-moving, frequently recurring fires.
Botany
Field surveys for TES plants within portions of the project area were conducted by
botany crew members in 2010, 2011 and 2012 for Clay phacelia, and by the botany crew
and botanist for other TES plants within the project area in 2012. Currently there is no
known occurrence of the Ute ladies’-tresses within the Sheep Creek Project Area
however there is some potential habitat present. One R4 sensitive species has been
located within the project area, (Wheeler’s Angelica, Angelica wheeleri), in the Tie Fork
and Indian Creek areas since the 2003 Revised Forest Plan was written, (during the 2012
botanical surveys).
Fisheries/Aquatics
Bonneville cutthroat trout and southern Leatherside chub are the only TES aquatic
species known to inhabit the management and/or project area, however, as mentioned
previously the project area contains suitable habitat for a variety of amphibian species
including boreal toad and Columbia spotted frog. Because there is potential habitat for
boreal toad and Columbia spotted frog, the ensuing analysis will consider impacts to
these species as if they were present in the project area. Bonneville cutthroat trout is a
management indicator species (MIS) for aquatic habitats on the Uinta-Wasatch-Cache
National Forest were historically present in Tie Fork and Soldier Creek. To my
knowledge, no cutthroat trout have been captured in Tie Fork since 1997 when they were
Environmental Assessment Sheep Creek Project
15
captured in Timber Canyon, a tributary; however, it is possible they are still present
somewhere in the drainage.
Direct and Indirect Impacts
The following table summarizes the effects from the two alternatives carried forward for
this project and disclose the direct and indirect effects, if any, to the resources evaluated
as part of this environmental analysis.
Table 2. Summary of Direct and Indirect effects to key resource indicators within the
Sheep Creek Project Area.
Resource Area Alternative 1 (No Action) Alternative 2 (Proposed Action)
Wildlife Big game winter range: expected
to decrease in quantity and quality
over time
TES: no effect to TE or TE
habitats, no listed species are
present. Four sensitive species will
not be impacted.
MIS: No impacts to 3 MIS species.
Migratory Birds: no effect to
migratory birds.
Big game winter range: expected to
increase in quantity and quality as
treatments are implemented
TES: this alternative will have no effect on
the Canada Lynx or its habitat. No other
listed species are present within the project
area. Four sensitive species and their
habitats may be impacted, but the species
are not likely to trend toward federal
listing.
MIS: Three management indicator species
and/or their habitats may be impacted.
These impacts are minor and will not lead
to a change in Forest trend.
Migratory Birds: Take may occur if work
occurs during the breeding season,
however project is consistent with USFWS
Order 131 and Executive Order 13186.
Hydrology Watershed Condition: watershed
conditions (ground cover, soil
stability, water quality) would not
improve under this alternative.
Watershed Condition: watershed
conditions (ground cover, soil stability,
water quality) would improve under
proposed vegetation treatments and travel
management actions.
Soils Soil Erosion: erosion is expected
to continue as a result in
decreasing ground cover,
proximity of FS Rd 691 to sheep
creek, and additional proliferation
of user created routes.
Soil Erosion: erosion is expected to
decline as a result of proposed vegetation
treatments and travel management actions,
and by the incorporation of project design
features that will protect soils during the
implementation of the proposed actions.
Cultural/Heritage Sites: No effect to sites since no
actions would occur under this
alternative.
Sites: No effect to sites as a result of
implementing project design features.

Range Rangeland Management: Ongoing
range management would occur as
shown on Allotment Management
Plans (AMPs). Juniper would
continue to encroach upon
rangelands reducing available
forage in the long term.
Rangeland Management: Ongoing range
management would occur as shown on
Allotment Management Plans (AMPs).
Available forage is expected to increase as
vegetation treatments improve rangelands.
Rangelands would be rested for 2 years
post prescribed fire.
Fuels Fuel Loading: fuels would
continue to build up over time,
increasing the risk of catastrophic
wildfire. Juniper encroachment
would continue to invade winter
range, resulting in loss of key
winter range browse and loss of
ground cover.
Fuel Loading: fuels would be reduced
under the actions proposed, mechanical
and prescribed fire. Juniper would be
removed on winter range, improving both
the availability of browse and increase in
ground cover by grasses and forbs.
Botany TES Plants: no effect to TES
Plants
TES Plants: no T&E (listed) plants will be
affected by the actions proposed. One
Sensitive species, Angelica Wheeleri may
be affected, but the effects will not lead to
a trend towards federal listing.
Fisheries/Aquatics TES Aquatic Species: no effect to
TES aquatic species.
TES Aquatic Species: no T&E Fish or
Amphibians are found within the project
area. Four sensitive aquatic species,
Bonneville cutthroat trout, southern
leatherside chub, Columbia spotted frog,
and boreal toads may be affected, but the
effects will not lead to a trend towards
federal listing.
Climate Change Trends: increased fuel build-up and
risk of uncharacteristically severe
and widespread forest fire in
traditionally fire-prone forest,
woodland, and shrub types, longer
fire seasons; atypical fire seasons
(e.g., winter, early spring), and
higher-elevation insect and disease
and wildfire events (large fires
already moving into true fir and
subalpine forests)
Trends: reduced fuel build-up and reduced
risk of uncharacteristically severe and
widespread forest fire in traditionally fire
prone forest, woodland and shrub types,
reduced potential for frequent fires and
allowance for fires of lighter intensity,
reduced stresses caused by overcrowded
and dense stands of trees that lead to
stressors (e.g. insect & diseases, high
severity fire), and maintenance,
enhancement or promotion of native,
diverse vegetative communities across the
landscape.
Past, Present, and Reasonably Foreseeable Future Actions
Each resource section includes a discussion of cumulative effects focused on evaluating
the effects of the proposed action in context with relevant effects from past, present, and
reasonably foreseeable actions. Past, present, and foreseeable future actions considered in
the cumulative effects analyses will vary for each resource. Relevant actions are those
Environmental Assessment Sheep Creek Project
17
expected to generate effects on a specific resource which will occur at the same time and
in the same place as effects from the proposed action. Past and present activities are
considered part of the existing condition and are discussed in the “Affected Environment
(Existing Conditions)” and “Environmental Consequences” section under each resource.
The analysis of cumulative effects is consistent with the direction provided in the 36 CFR
220.4(f). There is a summary in the next paragraph about the recently past, present (or
ongoing), and reasonably foreseeable activities within or near the general area of the
Sheep Creek Project that could contribute relevant effects (i.e., effects that overlap in
space and time with effects of the proposed action). The analysis for each resource may
not consider all actions listed below or it may consider additional actions not listed.
Past and Present Actions
Grazing- In the project area, cattle grazing occurs on approximately 9,000 acres of the
Sheep Creek drainage and sheep grazing occurs on a combined 13,104 acres in the
headwaters of Tie Fork drainage and most of the Indian Creek drainage. Cattle likely
have a greater impact to riparian areas due their tendency to be attracted to riparian areas.
Heavy use of riparian areas can lead to bank compaction and destabilization (i.e., loss of
fish and amphibian habitat), loss of riparian vegetation (i.e., fish and amphibian cover
and source of food), and the introduction of sediment to streams, which can impact fish
spawning grounds and aquatic insect production. No grazing occurs in the lower part of
Tie Fork the primary fish-bearing stream in the project area, but as grazing occurs in the
headwaters there is likely some sediment that is delivered to riparian areas and streams
which flow down into areas where hand removal project activities will occur. Any
sediment delivered to riparian areas from juniper removal will be short-term and should
lead to improved vegetative conditions in riparian areas. According to Leonard et al
(1997) prescribed burning may enhance forage production, palatability, and upland use;
therefore, grazing in Indian Creek should be evaluated or closely monitored following
prescribed burning in order to prevent additional impacts until the vegetation recovers.
Overall the Sheep Creek project should lead to an overall reduction in the amount of
sediment delivered to riparian areas.
Roads and Trails – Road and trail maintenance is occurring and will continue to occur in
the project area. Direct impacts from roads and trails to water resources include
interception/ concentration of stream or overland flows, increased erosion and stream
sedimentation, and encroachment on streams/floodplains/wetlands. Most of the roads in
the project area are found almost entirely in the RHCA’s; therefore, they will continue to
contribute sediment to nearby streams. Activities associated with the proposed action
may contribute additional sediment initially, but overall there should be a reduction in
sediment delivery. In particular, the gating of the Sheep Creek Road and restoration of
gullies in Indian Creek should lead to reductions in sediment.
Tie Fork Stream Crossings – This project proposes to replace and/or harden seven stream
crossings in the Tie Fork drainage with a primary goal to reduce sediment delivery to Tie
Fork Creek. The impact area for this project will be minimal (1-2 acres/crossing), and
although there may be some initial increase in sediment, eventually the project will
reduce sediment delivery to Tie Fork. Any overall reductions in sediment delivery will
Sheep Creek Project Environmental Assessment
Page 18
benefit Soldier Creek, which is currently on the state 303b list for excess sediment and
total phosphorous.
Juniper Lop and Scatter- During the last 4 years lop and scatter of juniper has occurred
off and on over 450 acres in Tie Fork. This activity has likely had little to no impact to
aquatic species in Tie Fork. Junipers have been left in place providing some additional
ground cover. Lop and Scatter has also occurred on 1,020 acres in the Tank Hollow
watershed. Tank Hollow is an intermittent stream; therefore, this activity should lead to
improved vegetative conditions, particularly in riparian areas. It will also have reduced
the risk of a stand replacing fire, which would have led to increased sediment delivery to
Soldier Creek.
Prescribed Fires – In 2007, 2,150 acres of prescribed burning was implemented in
portions of the Diamond Fork drainage (1st-4
th Water). The impacts of this activity were
likely short-term and would likely have had long-term beneficial impacts to vegetation.
In addition, due to the distance (stream miles) between this activity and the current
project area it is unlikely there would be cumulative impacts to aquatic species and their
habitats.
Dispersed Recreation – Dispersed recreation such as camping, hunting, fishing, and
hiking continue to occur throughout the project area. Impacts associated with these
activities include soil compaction and de-vegetation at camp sites or parking areas and
impacts associated with road/trail use for access. Generally, the percentage of the
analysis area affected by dispersed camping is minimal, resulting in negligible impact to
water and watershed resources. Impacts from motorized use are discussed above.
Transwest Transmission Lines – The proposed transmission lines would cross portions of
the Project Area, but impacts to aquatics would be limited as new lines would likely be
installed in in current transmission corridors and there should be little or no modifications
or impacts to riparian areas.
Timber Extraction – The White River Timber Sale (~220 acres) has been sold, but not yet
cut. There would be no cumulative impacts to aquatic species or their habitats in the
Soldier Creek drainage from this project as any sediment produced during timber
extraction would be delivered to the White River drainage.
Activities associated with private lands – The analysis area also includes limited privately
owned lands. Activities that occur on these lands include grazing, agriculture, road and
railroad construction/maintenance, and building construction/operation/maintenance.
These activities impact stream, floodplain, and wetland resources through groundwater
extraction, surface water diversion, and land use/vegetation conversion from
floodplain/riparian/native communities to agricultural or other uses. The proposed
action will not contribute to these impacts.
Prescribed Fire and Power Poles ___________________
Affected Environment
Environmental Assessment Sheep Creek Project
19
There is a Utility Corridor/Power Lines that runs through the project area, near the
prescribed fire treatment area.
Environmental Consequences
Alternative 1 – No Action
The no action alternative would have no effects on the power poles.
Alternative 2 – Proposed Action
The power poles in the area of the prescribed fire are along the border of the prescribed
fire unit. These power poles have very little vegetation around them and are not at risk
from the prescribed fire. The prescribed fire will not be ignited in the proximity of the
powerlines because the vegetation in that location is not what is desired to be treated to
regenerate aspen. Should the prescribed fire be in the vicinity of the power poles, their
proximity to the road would make them easily defensible from the fire.
Cumulative Effects
There are no other treatments that would affect power poles.
Air Quality ______________________________________
Affected Environment
When fire burns, smoke emissions occur; PM10 and PM2.5 are two of the emissions that
occur during fires. The National Ambient Air Quality Standard for PM10 is 150 µg/m3
and PM2.5 is 35 µg/m3 within a 24 hour period (EPA, 2010). The annual arithmetic mean
standard for PM2.5 is 15 µg/m3
(EPA, 2010). The EPA revoked the annual PM10 standard,
because available evidence does not suggest a link between long-term exposure to PM10
and health problems (EPA, 2010).
The Sheep Creek Project area is located within Utah County which has been designated
as a non- attainment area, for air quality, for PM2.5 (Utah DEQ, 2007). There are no Class
I areas near the project area. The project area lies within Utah Smoke Management
Airshed 6 for Utah.
All Prescribed fires must follow the prescribed fire requirements in the Utah Smoke
Management Plan (2006).
Alternative 1 - No Action
There would be no change in air quality due to smoke emissions because there would be
no management actions. However, by not treating the area the risk of more emissions
from a wildfire would increase, because a wildfire would most likely occur during the
Sheep Creek Project Environmental Assessment
Page 20
heat of the summer which would allow for more consumption of fuels and a longer burn
period which would increase the amount of emissions created.
Alternative 2 - Proposed Action
Smoke emissions would have a temporary impact on air quality, visibility and human
health within the West Vernon Project Area. Smoke emissions would occur only during
the prescribed fire portion of the proposed action. Using the Smoke Modeling software
(SASEM4), the predicted maximum smoke emissions concentration of PM2.5 would be
34 ug/m3, which does not exceed the EPA standard of 35 ug/m
3. Smoke emissions would
only have a temporary effect on visual quality in the area. The prescribed fire portion of
the project is located near Soldiers Summit. Smoke from the prescribed fire is not likely
to affect the Price or Utah Valley areas.
While preparing the burn plan, prescriptions are put in place to limit the quantity of
smoke emissions. One of the options include burning before new fuel appears (Smoke
Management Guide for Prescribed and Wildland Fire (NWCG 2001); this will be in the
burn plan since this burn will occur before new growth appears for the year. Another
option is to reduce the area burned (NWCG 2001); this will also be used since we will be
burning only in a portion of the project area and doing mechanically treatment in other
sites not the entire area. We want to have a mosaic pattern in the burn area, not one large
burned area. Inversions are not as common in the spring, which would help with smoke
dispersal. In order to be able to implement a prescribed fire the clearing index needs to
be above 500 this ensures that smoke will be mixed and dispersed into the atmosphere
and not concentrated in an area.
Cumulative affects
There would not be any cumulative effects. Smoke impacts are short-lived a few days to
a week. There are no other treatments that would be implemented within the area that are
currently planned, that would fall within that short timeline.

and safety, long-term soil productivity, and ecosystem sustainability, and
meet applicable laws and regulations.
Sub-goal-1-1
(G-1-1)
Forest Service activities, including those permitted by the Forest Service,
maintain or enhance the long-term productivity and physical, chemical, and
biological processes and functions of the soil.
Sub-goal-1-2
(G-1-2)
Long-term soil productivity is maintained on at least 85 percent of all activity
areas.
Sub-goal-1-3
(G-1-3)
Sufficient vegetation and litter are left on site to prevent soil movement and
maintain soil productivity.
Sub-goal-1-4
(G-1-4)
Ecological and soil conditions are meeting or moving towards desired future
conditions on 75 percent of the uplands and 80 percent of the riparian areas
classified as suitable for grazing.
Sub-goal-1-5
(G-1-5)
Sufficient vegetation is left on channel banks to catch sediments necessary for
streambank maintenance and floodplain development.
Sub-goal-1-7
(G-1-7)
Management activities do not cause exceedances of National Ambient Air
Quality Standards (NAAQS) (this monitoring is required by law).
Sub-goal-1-8
(G-1-8)
Activities on the Forest do not impede attainment of state clean air standards.
Sub-goal-1-9
(G-1-9)
Watersheds and their associated stream processes, channel stability, riparian
resources, and aquatic habitats are maintained or restored to a functional
condition.
Environmental Assessment Sheep Creek Project
25
Sub-goal-1-11
(G-1-11)
All activities on the Forest comply with state and federal clean water
standards and applicable permitting processes. To the extent practical through
management of activities on the Forest:
Water chemistry is maintained in all surface water where the alkalinity
will not be reduced more than 10 percent of baseline, and
Management activities do not cause exceedances of State of Utah
water quality standards (this monitoring is required by law) or
increases in the listing of 303(d) streams.
FW-Goal-2 Biologically diverse, sustainable ecosystems maintain or enhance
habitats for native flora and fauna, forest and rangeland health,
watershed health, and water quality.
Sub-goal-2-1
(G-2-1)
The fuel management aspect of the fire management program is emphasized
through application of hazard reduction activities.
Sub-goal-2-2
(G-2-2)
Fire is managed in an economically efficient manner, based on resource
values and risks to human life and property.
Sub-goal-2-3
(G-2-3)
Fire is reintroduced as an ecosystem function to move landscapes toward
desired conditions.
Sub-goal-2-8
(G-2-8)
Ecosystem resilience is maintained by providing for a full range of seral
stages and age classes (by cover type) that achieve a mosaic of habitat
conditions and diversity to meet a variety of desired resource management
objectives. Recruitment and sustainability of some early seral species and
vegetation communities in the landscape are necessary to maintain ecosystem
resilience to perturbations.
Sub-goal-2-10
(G-2-10)
Management actions maintain ecosystem health and encourage conditions that
are within the historic range of variation. Management actions remain within
the variability of size, intensity, and frequency of native disturbance regimes
characteristic of the subject landscape and ecological processes.
Sub-goal-2-11
(G-2-11)
Key shrubs and/or trees are maintained to a level that allows adequate
recruitment to maintain or recover the woody component. Specifically, the
Forest is managed for more plants in the combined sprout and young
categories than in the combined mature and dead categories.

(G-2-25)
Maintain stable and upward conditions in big game winter range habitats and
improve downward trend sites.
Sub-goal-2-26
(G-2-26)
Wildlife travel corridors, riparian corridors, and key linkage routes are
maintained and, where feasible, restored. Connections among large,
contiguous blocks of suitable habitat are provided (e.g., key linkage routes for
Canada lynx within and between Lynx Analysis Units [LAUs] and big game
summer and winter range movements). Wildlife movement is facilitated
within key linkage areas, considering highway crossing structures when
feasible. Unified management direction is established through cooperation
with other ownerships via habitat conservation plans, conservation easement
or agreements, and land acquisitions.
Sub-goal-2-38
(G-2-38)
Healthy, self-sustaining riparian communities, habitat for viable populations
of aquatic life, and conditions for natural stream dynamics exist on the Forest.
Sub-goal-2-42
(G-2-42)
Recreation facilities (including trails and dispersed sites) are designed,
constructed, and operated in a manner that does not retard or prevent
attainment of aquatic Forest Plan management direction.
