Project Need
Need For Project:
This project is a watershed landscape scale level project and has been identified as part of a national priority landscape. We have collaborated with multiple landowners and agencies over the past few years to treat the entire watershed, and this project is a continuation of this work. This watershed has many threats to its health and the sage-grouse population declines in certain areas are a symptom of these threats. Large fires, cheatgrass invasion, post fire seed mixes full of crested wheatgrass, pinyon and juniper tree encroachment, creek channel down-cutting, and the loss of wet meadow habitat are all threats that are reducing the health of the North Sheeprocks Watershed. This watershed is crucial for sage-grouse, mule deer, trout sp., amphibians, species of bats like little brown bats, turkey, raptors such as Ferruginous hawks, and many other species' survival. Livestock grazing is also an important part of the livelihood of residents of this watershed. These threats reduce the quality of the range for livestock grazing. The town of Vernon is located in this watershed and the benefits from this project will help protect them from wildfire. We will also work to improve the quantity and quality of water in this watershed. This project is designed to address these threats and benefit the entire watershed through a landscape-scale approach.
The loss of sagebrush habitats from PJ encroachment and fire has been occurring in other areas as well across the west and this important habitat type continues to decline under the many threats that impact it (Bradley 2010, Miller and Eddleman 2000). One of the greatest threats to this habitat type is the encroachment of pinyon pine (Pinus edulis) and Utah juniper (Juniperus osteosperma) (PJ) trees into these sagebrush habitats (Bunting et al.1999). Through fire suppression, historic livestock over-grazing, and changes in climatic conditions, PJ has encroached into areas once dominated by sagebrush (Tausch 1999). When PJ canopy cover and tree density reaches certain levels they outcompete other vegetation and the diversity and density of understory vegetation (shrubs, grasses, and forbs) decline. This removes an important component of food and shelter for elk, mule deer, sage-grouse, sage sparrows, and small mammals, such as jackrabbits and cottontails, which are a large component of golden eagle diets (Bates and Moretti 1994, Naillon et al. 1999, Vaitkus and Eddleman 1991). In addition to out-competing understory vegetation, increased tree densities within sagebrush parks have been proven to reduce the use of these habitats by sage-grouse. Sage-grouse avoid these areas because of the increased risk of predation by aerial predators (e.g., raptors) that can use these trees as perches (Commons et al. 1999). Thus, the potential habitat for this imperiled bird is lost.
Another important habitat type for sage-grouse (but also for many species found in these landscapes that rely on limited water sources) is where the shrubs meet aquatic zones that provide an increase in meadow type habitat. These habitats provide high protein content vegetation and insects that are critical for early chick development and survival. Much of this habitat type has been lost from drought, beaver removal, and creek bed incision. The continued erosion of the creek bed from high flood events has made it so water never reaches outside the banks to increase meadow habitat along the riparian corridor. This project will work to restore the natural floodplain of these creeks and increase wet meadow habitat by building and maintaining BDAs. Wet meadow habitat is one of the limiting factors in this arid environment. Many of the creek banks have been eroded and historic wet meadow habitat has been lost. This project will repair these eroded banks and raise the stream bank back up. This will increase the vegetation along the creeks banks and increase the wet meadow habitat that is important for brood rearing sage-grouse and other wildlife, such as turkey, mule deer, bats, pronghorn, and more that utilize these riparian areas and streams for water. This project will also improve the habitat within the stream channel for fish and other aquatic species. Frog species like northern leopard frogs and potentially Columbia spotted frogs and other amphibian species that are being threatened across the state will benefit from the increase in habitat. By improving the riparian and wet meadow habitat we will also increase the amount of forage available for big game (deer, pronghorn, elk) and livestock. Bennion Creek and Lee Creek are located within prime brood-rearing habitat. All of these creeks have been degraded and channelized in spots from human causes, livestock damage, and erosion. This channel incision results in steep and deep banks that are dangerous for livestock and wildlife and make it difficult for animals to drink. It also causes more water to be lost from the system and less vegetation to grow along the banks that could be used by livestock and wildlife. The creeks in this area historically likely had beavers that would dam the stream and slow the water so it would not erode as heavily and cut as deep into the ground. These beaver dams would also create meanders, and flooding the stream banks which would water more plants. This flooding would increase soil moisture across a larger area and produce more wet meadow vegetation along the banks. These natural meanders also helped to reduce channel incision and erosion which results in a loss of habitat. The loss of this habitat has likely attributed to the decline in sage-grouse. Beaver re-introduction in some areas is not always plausible politically or biologically. This area is one such area that may not be a good candidate for re-introduction. Instead we plan to build man-made beaver dams called beaver dam analogues or BDAs to replace the lost ecological function that would exist if beavers were in the system and to repair damage that has been caused by other means. Also, BDAs will help store water longer in the watershed so that water will not just all come at once in a big flow, but will last longer into the summer in a more steady and consistent flow. The benefits to water quantity and quality from BDAs area many. In addition to these benefits BDAs can increase the size of the riparian zone and create a green strip that can be used to slow and stop wildfires.
From the loss of habitat and other threats the sage-grouse population within this area is at risk of becoming extirpated. Population numbers are extremely low and have dropped below population viability thresholds. Sage-grouse have been trans-located to the area to help boost the population, but treating the causes of the population decline is also essential to maintaining this population. We must do everything in our power at this time to benefit this Sheeprocks' sage-grouse population to give them a chance of remaining. If we lose this population it will be devastating to all efforts to keep the bird from becoming listed as an endangered species. Therefore, all priority needs to be placed on the Sheeprocks area at this time to show that we are managing these species correctly and are not in need of federally listing the bird. If sage-grouse become federally listed it will have negative impacts on private landowners, ranchers, energy development, and the actual conservation of the bird. Sage-grouse are not the only species that is in need of this project. Other wildlife like mule deer will greatly benefit. If this project doesn't occur and the remaining understory is lost the results will be devastating to the deer herd. It will be more likely that animals will not survive the winter and population numbers will decline. Inversely, by doing this project we will increase the available forage and help to grow the deer herd and improve body condition, which helps to grow big antlers and more bucks. There are still remaining many bitterbrush, cliffrose, and sagebrush plants, in the understory that we need to protect. Much of the project area is found within phase I PJ encroachment and every year that goes by without treating increases the cost of treatments in the future and the loss of habitat. This project will also have a lop and scatter treatment to remove this encroaching pinyon and juniper. The advantage of this project over others that are located in more phase III PJ encroachment is that because we still have lots of mature understory plants remaining, once the PJ is removed, we will have immediately created suitable habitat for sage-grouse and protected large shrubs for mule deer to eat. Project areas that have already lost their understory will not be suitable habitat for sage-grouse for many years to come. The sage-grouse population in the sheeprocks cannot wait and all priority needs to be aimed towards projects that will provide an immediate result. In addition to sage-grouse and mule deer there are many other wildlife species that can benefit from doing work to prevent the loss of sagebrush and other understory vegetation. In portions of the watershed there have been historic fires that were re-seeded with nonnative seed mixes. Species like crested wheatgrass have dominated and result in a monoculture of non native grasses. These grasses don't allow for natural succession to take place and shrub species are not able to naturally establish in the system. So as part of this project we have identified one of these areas near the Benmore Lek where the shrub component has been lost and we will plant and seed shrubs to get shrubs back. This will improve the critical nesting habitat around the lek and increase the nest success that is so important for the population to persist. These plantings though will be important to other species that use shrubs for forage and cover such as mule deer, small mammals like cottontails and jackrabbits, and in turn those who prey on these species like raptors (e.g. Ferruginous hawks). By doing all of these improvements to this watershed we will have many positive impacts to the ecosystem, to the economy, and the local residents.

Project Location/Timing Justification (Why Here? Why Now?):
The Sheeprocks/Vernon Management Area has been identified as a critical watershed for the protection of the urban interface, wildlife, and an economic benefit to forest users and State entities. To date the majority of the restoration work has been focused on reducing the threat of wildfire and restoring the natural condition of the landscape. This project and future projects aim to protect, maintain, and improve habitat function and monitor for a sustainable diversity. Within many of the State and Federal planning documents, this area and/or the habitat-type of this area is addressed as crucial to maintain and improve. For example, Utah's Wildlife Action Plan identifies sagebrush-steppe habitat (including the lowland and mountain sagebrush this project works in) as a key habitat, especially since it supports mule deer, greater sage-grouse, and numerous other species of concern. These habitat types are also identified in the Utah WAP as at high risk to natural system modifications, such as fire and fire suppression (very high threat for greater sage-grouse and lowland sagebrush). Another threat is other ecosystem modifications, such as channel downcutting, brush eradication/vegetation treatments, and seeding non-native plants, all of which are very high and high threats to lowland sagebrush, mountain sagebrush, and greater sage-grouse. Other state and federal documents that address this area, its habitat type, or the species that rely on this area state the need for pinyon-juniper reduction or vegetation treatments for greater sage-grouse (WDARM sage-grouse conservation plan, Uinta Forest Plan, Vernon Management Area of Uinta NF Plan, Utah Greater Sage-grouse Management Plan, WAP, etc.), mule deer (Mule Deer Unit 19b Mgmt Plan, Uinta NF Plan and Vernon Management Area, WAP, UDWR Statewide Management Plan for Mule Deer, etc.), and for desired future conditions of the area (Vernon Management Area of the Uinta NF Plan). This area is clearly an important area where multiple entities have given thought towards the conditions needed to maintain critical habitat types and species of concern.
Much work has been done to study species of concern within the Sheeprocks as well, which can be seen through all the collar data for greater sage-grouse, mule deer, pronghorn, and elk. Our project has picked this year's specific locations based on where previous work has been done, past fire occurrences, but also based on wildlife location data (see photos section). Shrub planting for greater sage-grouse is occurring in past fire areas where little sagebrush is left, but also because this area is critical for the Benmore lek. Most of the sage-grouse locations from past research shows that our outlined areas are heavily used by grouse. With this year's lop and scatter in the lowlands, we hope to continue connecting areas that are encroached upon by PJ (connecting our previous lop and scatter or mastication work to the sagebrush dominated areas), so that they may become available to sage-grouse for further use. These areas also though provide key habitat for mule deer.
The research that has been done on sage-grouse in this area indicates that the work we have done, and plan to continue doing, is needed now or else we risk the extirpation of this population. Population numbers have dropped below viability thresholds, which is one reason why translocation efforts were conducted (Chelak and Messmer 2016). It is essential though that we address the root of the issue to improve and encourage population stability. The 2020 Annual Report & 2021 Research Update from Utah State University (Chelak & Messmer 2021) said that though all 11 of Utah's SGMAs showed gradual declines in populations (Garton et al. 2011), "the Sheeprock SGMA population has continued to decline while others showed increasing population levels." If these habitat improvements do not continue to occur and the remaining population is lost, it will be a devastating loss and a disservice to all our efforts to keep this population alive and this species off the Endangered Species Act.
In addition, it is important to address (now and into the future) the threat of high intensity fire that these lowland sagebrush areas in the Sheeprocks experience due to the greater amount of annual grasses, decreased mosaics, loss of shrubs and forbs, etc. The 2007 Northern Utah Regional Wildfire Protection classifies the Sheeprocks as a moderate-high risk for wildfire, and our project helps to minimize that risk through fuels reduction (PJ treatments), shrub plantings to create a mosaic, and BDAs to help storage water longer and increase the riparian zone, creating a green stripe to slow and stop wildfire.
Relation To Management Plan:
1. Vernon Ecosystem Management Plan
The desired condition for pinyon/juniper in the Vernon Ecosystem Management Plan for Vegetation (USDA 1996) is to maintain greater than 85 percent of potential ground cover on pinyon-juniper sites and to remove pinyon-juniper on sites with less than 30 percent slope. This desired condition for pinyon-juniper was developed to mimic conditions created by past fire regimes and is within the range of natural variability for the Vernon Ecosystem.
2. Wildlife Action Plan
Project area occurs within the sagebrush steppe type, one of the key habitats identified in the WAP. This area supports mule deer (Tier III) and Greater sage grouse (Tier II) and numerous other species of concern (Tier III) including neotropical birds and raptors.
3. WDARM sage-grouse conservation plan
Treatments address strategies outlined in the WDARM sage grouse conservation plan; reduce pinyon/juniper stands from sage-grouse use areas. Increase brood-rearing habitat quality in the Resource Area. a) Reduce pinyon/juniper stands from sage-grouse use areas. b) Remove pinyon/juniper trees from priority areas where action is warranted. c) Revisit and retreat pinyon/juniper removal sites, as needed. d) Maintain or increase distribution and quality of mesic sites available to sage-grouse during summer months. e) Maintain or improve breeding habitat quality in the Resource Area. f) Minimize weed concerns This plan addresses the removal of PJ which will welcome the SG to utilize the forage and open water that crosses portions of this property. Reseeding disturbed areas will mitigate weedy species concerns, and expand habitat for this population. http://utahcbcp.org/files/uploads/westdesert/WDARMSAGRPlanFinal.pdf
4. Mule Deer Unit 19b Mgt Plan
Objectives/Strategies: a) Reduce expansion of Pinyon-Juniper woodlands into sagebrush habitats and improve habitats dominated by Pinyon-Juniper woodlands by completing habitat restoration projects like lop & scatter, bullhog and chaining. b) Condition of winter ranges is a long-term problem. c) Fire and encroachment by pinyon and juniper trees results in the loss of forage production, diversity and quality. d) Cooperate with federal land management agencies and private landowners in carrying out habitat improvement projects. e) The primary concern on the studies within the subunit is the abundance of weedy annual grass species (cheatgrass), particularly on the lower elevation sites. This plan addresses the condition of winter range in the project area by dealing with PJ expansion, condition of winter range by planting browse species, reducing fuel loads, coordinating with Federal land management agencies, and mitigating weedy annual grass species. http://wildlife.utah.gov/hunting/plans/deer_19.pdf

This plan addresses improving and restoring Mule deer habitat, by working in cooperation with partners, mitigating invasive annual species, ensuring that seed mixes contain sufficient forbs, and browse species, and improving sagebrush-steppe. https://wildlife.utah.gov/hunting/biggame/pdf/mule_deer_plan.pdf
9. BLM Pony Express Resource Management Plan (1988) Wildlife Goals and Objectives 1. Manage wildlife habitat to favor a diversity of game and non-game species.
Project Relevance: We will be removing PJ which will protect a larger diversity of plant species upon the landscape. 2. Continue to provide forage for current big game numbers or long-term management goal numbers,.
10. Utah Partners in Flight Avian Conservation Strategy Habitat Objectives: Sage-grouse- 7. Eliminate or modify habitat components that facilitate predation on Sage-grouse.(pg. 77) -
This project will help to eliminate trees that predators such as raptors may use as perches to prey on sage-grouse. This will allow for sage-grouse to also feel more comfortable inhabiting these sage-brush parks that used to be filled with pj.
11. Beaver Management Plan Watershed Restoration
1. Support restoration of beaver and adequate protection where establishing
2. Consider using beaver as a stream restoration tool
3. Beaver are a good tool that could be used to restore degraded riparian communities that could benefit many other wildlife species
4.Need to consider the site characteristics of the locations where beaver will be relocated/re-introduced enough vegetation to support a beaver population
5. Potential benefits of aspen/cottonwood restoration in improving beaver habitat
Outreach and Education Objective 1: Increase awareness of and appreciation for the role of beaver in Utah's ecosystems in 10% of stakeholders (landowners, educators, recreationalists, sportsmen, water rights holders) by 2020. We will be working with private landowners and citizen scientists to educate them about importance of beavers in ecosystem. 4. Establish at least one showcase beaver management area in each UDWR Region. Objective 2: Improve the understanding of all UDWR and other governmental agency employees involved in beaver management and assure consistent transmission of information and application of management actions through 2020. Watershed Restoration Objective 1: Work to improve riparian habitats, associated streams and wetlands in a minimum of 10 tributaries through translocating beaver into unoccupied suitable habitat on public and/or private land by 2020. This project will not be translocating beavers at this time to this area, but through the use of BDAs we will be re-introducing the functionality of beavers in the system. Also we will be improving the habitat and preparing an area so that in the future beavers can be re-introduced.
12. Statewide Elk Managment Plan
1. Increase forage production by annually treating a minimum of 40,000 acres of elk habitat.
2. Maintain sufficient habitat to support elk herds at population objectives and reduce competition for forage between elk and livestock.
13. Statewide Turkey Managment Pan Objective Increase wild turkey habitat, quality and quantity, by 40,000 acres statewide by 2020.
Fire / Fuels:
Fuels have been accumulating over the years due to human cultural practices and changing climatic conditions. The 2007 Northern Utah Regional Wildfire Protection Plan designates this area as a Moderate-High Risk area for wildfire (Utah Division of Fire, Forestry and State Lands 2007). Hazardous fuels reduction treatments would help minimize the risks to private land, structures, and natural resources, from potential wildland fires. The nearby communities of Vernon and Lofgren are listed as two of Utah's Communities at Risk (Utah Division of Fire, Forestry and State Lands 2013). The implementation of this project would help minimize the risks to private land, structures, and natural resources, from potential wildland fires by: 1) altering fire behavior from a crown fire to a surface fire, 2) increasing native plant populations and their resiliency, 3) reducing the risk of weed expansion, and 4) protecting critical mule deer habitat from unwanted fire effects. The current fuel load and arrangement is likely to support a relatively severe fire due to continuous, dense pockets of juniper and oak brush. The proposed treatment would reduce fire behavior to a more controllable fire by breaking up the continuity of fuels. This alteration in fire behavior not only enhances firefighter and Forest visitor safety, but increases the ability of the plant community to recover post-fire by reducing the fire severity. This project will increase the sinuosity of the stream, raise the water table, slow water movement through the system and reconnect the channel with its historic floodplain. This will increase the amount of riparian vegetation which will create a larger fuel break to stop fires from spreading and destroying more critical wildlife habitat. It will also create a location where firefighters can more easily combat the fire. By having younger shrubs that are not as decadent and dry as older dying shrubs it will reduce the risk and severity of fire. Hopefully it will serve as green strip areas where fires will slow or stop. By maintaining healthy stand of shrubs and native plants it will prevent annual grasses from establishing that can increase the fuel load and dryness of plants that increase fire risk.
Water Quality/Quantity:
Beaver Dam Analog benefits to water quality and quantity: Currently in areas where the stream-bank has been stripped of vegetation due to erosion, resulting in more downcutting, this leads to further erosion and diminished water quality. This project will help to raise the water levels and allow for more vegetation to be growing near the water to stabilize the banks. This will help increase the water quality and quantity in the system. This project will also slow the flow of water which will decrease the amount of erosion that will occur in big flood events. Slowing the water will also increase the quantity of water that is able to seep into the soil and benefit the system. This will also hold water longer upstream and increase the length of time that the reservoir downstream can hold water, thus increasing its capacity and water quantity.
PJ removal benefits to water quality and quantity: PJ removal will help to establish vegetation that will stabilize the soil and help to reduce the amount of sediment that will enter streams and washes. This will help to improve the water quality of the watershed. Also, currently moisture will move across the soil more quickly and water quantity will be lost. This project will help establish vegetation that will hold more moisture in the system and allow for it to soak into the soil and enter under ground water storage. Another negative impact on the watershed from PJ encroachment is soil erosion (Farmer 1995). By removing PJ it will allow for the current grasses and forbs to return and stabalize the soil and decrease the speed of water-flow and the size of soil particles that can be moved downstream and therefore reduce erosion. This project will help to protect this from happening in the future and save the ecosystem from irreversible losses to soil. Cut trees will also be placed in washes to slow the flow of water and promote pooling and reduce them eroding as quickly. In water-limited systems, an added benefit to PJ removal can be the potential to increase water-savings. PJ have been shown to intercept about 10-20 percent of precipitation (Skau 1964). Also, where PJ encroachment has resulted in large bare ground areas it has been shown that these systems can have greater precipitation runoff (Farmer 1995). Results of the Great Basin Landscape Conservation Cooperative study in Nevada (Desatoya Mt.) found that by removing (lop and scatter) P/J (130 trees/acre) there is the potential to increase water recharge yields 4% on wet years. On wet years this will increase recharge, but does not increase stream flow. Wet meadows and upland plants benefit by utilizing the increase soil moisture, providing for better resiliency during drought years. This provides for an increase in water quantity for herbaceous plants on sites where p/j is removed. By removing PJ on this project we will be preventing the increased loss of water from occurring. This project is very large and has the potential to make a large impact on the watershed;1.12 miles of streams are within the planned project area polygons.
Shrub restoration benefits to water quality and quantity: By having a healthy diversity of age class shrubs it will prevent a mono-culture of old decadent plants which can die off and result in invasion of weedy plants such as cheatgrass. Cheatgrass will absorb all of the available water and decrease the plant diversity. By doing this project there will be more available water for native understory plants to increase diversity.
Compliance:
Categorical exclusion has been used by the USFS to maintain the current state and transition model. NRCS CPA-52 looks at all impacts to the area of concern including soils, water, air, plants, animals, human, and energy. It also looks at all resource concerns and provides the landowner or permittee with alternative choices for ways of dealing with resource concerns. NEPA and Stream Alteration permits have already been completed for Vernon, Little Valley, and Bennion Creeks. The UDWR or Forest Service will conduct any necessary archaeological clearances in-house for this project. Any needed water rights will be purchased as well. The UDWR has already created an agreement with SITLA to get water rights for 35 BDAs a year.
Methods:
PJ Removal: To remove PJ we will contract chainsaw hand crews to lop and scatter. We will not need to seed in lop and scatter areas because there is still an understory. Remove smaller Junipers and Pinyon pines <10" in diameter measured at each stem or stems where they meet the bole or bole's nearest the root collar / stump of the tree in shrub-steppe and grassland areas that have less than 20% canopy cover. Remaining stumps will be no higher than 6 inches, Trees will be cut into approximate 3 foot lengths and branches scattered across the site. Scattered material should not exceed a height/depth of 24 inches. Chainsaws and /or loppers would be used in the project areas. All travel between sites will be on foot or on existing roads and trails.
BDA Construction: We will construct the BDAs with sharpened lodgepole fence posts, approximately 3-4" diameter. They will be driven into the stream bed with a gas post pounder or hydraulic post pounder. The posts will extend about 1 m above the channel bed. The posts will be spaced approximately 0.5 - 0.8 m apart, and driven to a depth of approximately 1 m into the streambed. We will then weave willow branches or other tree branches that are available onsite between the posts to create a structure that will look like a beaver dam. The willows will help to slow the water but will also allow fish to pass through. We will then reinforce the posts with stream bed material at the base of the posts. The idea is that the dams will last until sediment is piled up at the dam and vegetation begins to grow and the stream channel rises and floods. We will place dams about 30 m apart, depending on where they need to go. After a year we will assess the health of the stream again and determine what progress has been made and where future BDAs need to be placed. Once sediment has built up behind the dam we will plant the wetland sod mats to speed up recovery and have the roots hold that built up sediment in place.
Shrub Restoration: We will also use a dozer to scalp 2' wide rows into the thick crested wheatgrass areas. The bare soil will reduce competition from grasses and allow for natural seeding to occur. We will also broadcast seed and use dribblers to augment the amount of seed and diversity of species. We will also be planting two year old shrubs with vexar mesh protectors to help increase survival.

BDA monitoring: In 2018, we began monitoring bats and we are asking for additional funds to continue this monitoring this year to monitor whether BDAs improve the area for bats, including Little Brown Myotis (Myotis lucifigus), a SCGN in the 2015-2025 Wildlife Action Plan. We plan to monitor for bats by following the protocol for the North American Bat Monitoring Program (NABat), which uses stationary acoustic devices, driving surveys, and possibly mist-netting to detect bat activity. We plan to set acoustic monitoring equipment at sites were BDAs were installed in 2017 as well as sites where new BDAs are planned for installation, to try to determine if bat activity differs between sites. Data collected from the grid encompassing the Vernon BDA project area will also be included in the nationwide NABat program.
PJ Treatments: In PJ Treatments we will take photo points before and after at a few select locations. We will monitor the project for greater than 1% of Phase 1 pinyon/juniper re-establishment in year 3 and 5 post treatment. If re-treatment becomes necessary we will pursue retreatment options. In addition, this year we are requesting acoustic monitoring equipment to monitor pre- and post treatment areas for this project and future Sheeprocks projects to evaluate any potential impacts on bird, and potentially bat, communities. Getting baseline data of what bird species are present already in these PJ areas, such as if there are Pinyon-Jays, will be crucial for understanding whether these treatments help or hinder bird communities immediately as well as impacts after several years.
Shrub Restoration: We will take photo points before and after the project. We can go back in several years and retake them to show how effective the project has been. We will also keep track of the survival of shrub plantings to determine how successful they were.
Partners:
The U.S. Forest Service is partnering and collaborating on this project with biologists from the Utah Division of Wildlife Resources to identify areas and treatment methods that will be most beneficial for wildlife in the area. All partners for this year's project proposal include: United States Forest Service, Private Landowner, Division of Wildlife Resources, Bureau of Land Management, and SITLA (Utah Trust Lands Administration). The UDWR contacted several partners to ensure connectivity for stream and riparian area restoration through BDAs in Lee Creek since several boundaries would be crossed (BLM, SITLA, and Private Landowner). These partners will be informed of the timeline for implementation on each of their lands. Shrub restoration and lop and scatter of PJ will be on solely FS lands this year. Permittees on FS land are an important stakeholder and will be notified of project activities as well.
Future Management:
The area will be managed according to the Uinta National Forest Land Management Plan and Vernon Grazing Allotment Plan which includes a rest rotation grazing system. We will continue to monitor the success of BDAs in the future and make any repairs or adjustments as needed to ensure their success. We plan to do future plantings or seeding as needed across the areas where fire has reduced sagebrush over the next several years. The Forest Service will work with the UDWR to continue to build upon these improvements to benefit the habitat in this area. There may be further work to introduce aquatic species. The U.S. Forest Service will monitor grazing to see if fencing will need to be built in the future, or whether reductions in livestock grazing will be needed, to ensure the success of the project.
Sustainable Uses of Natural Resources:
The Sheeprocks is an important area for livestock grazing, and the reduction in overhead canopy will increase the amount of grasses and forbs produced within the project area, allowing for greater vegetation/feed for livestock. Livestock that utilize this area will also benefit by having an increase in vegetation around the streams from BDAs, which will increase the amount of available forage. They will also be able to access the water more easily without causing added damage to the stream bank. The Sheeprocks is a highly visited area for recreation (e.g., camping, hunting, fishing at the reservoir, ATV and dirtbiking, etc.). This project will help increase and make it possible for recreation to continue in the Sheeprocks by promoting a healthy watershed that can endure recreation.
