Need for Project
Cheatgrass has become the most abundant invasive species in the nation. Cheatgrass can negatively influence ecosystems and have economic impacts by displacing native plants, increasing wildfire events, reducing yields, and reducing biodiversity. Cheatgrass has become more prevalent in the four different habitat project areas proposed (7,102 acres) that have previously been implemented on BLM and SITLA lands. Plateau herbicide would be applied aerially in the fall of 2019 on the entire project area application to help control the cheatgrass infestation. Herbicide control was chosen because it is one of the most cost-effective weed treatments for large areas and has a low level of soil disturbance. Cheatgrass infestations can influence the habitat, food and shelter of many wildlife species and livestock. The Deadman Bench, Snake John and Raven Ridge areas encompass greater sage-grouse winter and brood-rearing habitat, BLM designated General Habitat Management Area, greater sage-grouse leks within 3.1 miles of the areas, mule deer winter crucial habitat, pronghorn year-long crucial habitat and several raptor nests within the area (i.e. golden eagle and ferruginous hawk). The Shiner Basin treatment area encompasses, greater sage-grouse winter and brood-rearing habitat, BLM designated Priority Habitat Management Area, State of Utah Designated SGMA, greater sage-grouse leks within and within 3.1 miles of the treatment area, elk crucial winter habitat, mule deer crucial winter habitat, and white-tailed prairie dog colonies. The Cherry Springs treatment area is encompassed greater sage-grouse winter and brood-rearing habitat, BLM BLM designated Priority Habitat Management Area, State of Utah Designated SGMA, greater sage-grouse leks within and within 3.1 miles of the treatment area, elk crucial summer habitat, and mule deer crucial summer habitat.
Provide evidence about the nature of the problem and the need to address it. Identify the significance of the problem using a variety of data sources. For example, if a habitat restoration project is being proposed to benefit greater sage-grouse, describe the existing plant community characteristics that limit habitat value for greater sage-grouse and identify the changes needed for habitat improvement.

Objectives
The goal of this project is to use Plateau herbicide aerial treatments to address the existing cheatgrass infestations in the treatment areas and to try to reduce the increase/% cover and spread of cheatgrass while allowing the desirable native plants to flourish.
Provide an overall goal for the project and then provide clear, specific and measurable objectives (outcomes) to be accomplished by the proposed actions. If possible, tie to one or more of the public benefits UWRI is providing.

Project Location/Timing Justification (Why Here? Why Now?)
If these areas are not treated, ecological, economical, and restoration costs could all be affected due to cheatgrass infestation. Invasive Plant Species--Non-native: Cheatgrass is highly prolific and a competitive winter annual weed. Cheatgrass has a tendency to displace native vegetation quickly, which can cause a decrease in important habitat and quality forage for wildlife and livestock. When cheatgrass starts displacing native habitats, for example the sagebrush steppe, local economies and over 350 species of plants and animals that rely on the sagebrush for food, forage and shelter are negatively impacted. Fire and invasive plant species are one of the primary threats to greater sage-grouse and their habitats. Cheatgrass has invaded the project areas, through the use of Plateau herbicide, this project aims to reduce these impacts from cheatgrass invasion. Inappropriate Fire Frequency and Intensity: Cheatgrass can affect fire regimes because of the continuity of the fine fuels it creates. The fire return intervals are shortened because of the fine fuels, which does not allow for complete recover of perennial vegetation before the next fire. The shortened fire return intervals allow the cheatgreass to outcompete native vegetation and spread rapidly, promoting lager and more frequent fires. Fire does destroy the cheatgrass plant, but usually does not harm the thousands of cheatgrass seeds in the soil, thus the cheatgrass seedbank outcompetes native plants and can destroy native ecosystems quickly. Due to the presence, and potential expansion, of cheatgrass in the project areas, fire frequency and intensity is likely to increase, which would further damage the area and reduce its value for greater sage-grouse and other wildlife and livestock that utilize the area. This project aims to reduce this risk through the chemical control of cheatgrass.
LOCATION: Justify the proposed location of this project over other areas, include publicly scrutinized planning/recovery documents that list this area as a priority, remote sensing modeling that show this area is a good candidate for restoration, wildlife migration information and other data that help justify this project's location.
TIMING: Justify why this project should be implemented at this time. For example, Is the project area at risk of crossing an ecological or other threshold wherein future restoration would become more difficult, cost prohibitive, or even impossible.

Relation to Management Plans
Vernal Approved Resource Management Plan-BLM: FIRE-4- Hazardous fuel reduction activities will be implemented primarily through the use of prescribed fire and managed wildland fire. In some cases, chemical and/or mechanical treatments will be used in conjunction with fire. Where social and/or resource constraints preclude the use of fire, mechanical and/or chemical treatments will be used. FIRE-5- Criteria for developing hazardous fuel reduction priorities will consist of the following: * Areas of Fire Regime Condition Class 2 and 3 * Areas where the potential risk of losing keystone ecosystem species is present * Areas where threats to private/public property exist VEG-1 - Allow mechanical, fire, biological, or chemical control of noxious weeds and insect infestations within the resource planning area with restrictions to protect desired ground cover and water quality. Use the type of manipulation appropriate to and consistent with other land use objectives. VEG-2 - Continue implementation of noxious weed and invasive species control actions as per national guidance and local weed management plans (WMPs) in cooperation with state agencies, federal agencies, county governments, private landowners and other partners or interests directly affected. VEG-3 - Utilize principles of integrated pest management for the control and management of noxious weeds and invasive species. These include prevention and control through mechanical, cultural, biological, and chemical methods. VEG-4 - Manage the vegetation to attain the ecological stage that will benefit wildlife in crucial habitat and livestock grazing. Manage vegetation in remaining areas that results in high vegetation species diversity. VEG-9 - Manage the vegetation to attain the ecological stage that will: * Ensure sustainability; * Meet authorized use allocations (such as livestock and wildlife); and * Ensure species diversity. VEG-10 - Manage the vegetative types to achieve the desired mix of seral stages, as outlined in the ROD page 134. MCA-5 - Appropriately manage noxious and invasive weeds and prevent introduction of new invasive species through the implementation of a comprehensive weed program per national guidance and local WMPs, including coordination with partners; prevention and early detection; education; inventory and monitoring; and using the principles of integrated pest management. MCA-6 - All projects that involve ground-disturbing activities shall incorporate best management practices (BMPs) for control of weeds with an emphasis on prevention. MCA-7 - Use of pesticides and herbicides shall comply with the applicable federal and state laws. Pesticides and herbicides shall be used only in accordance with their registered uses and within limitations imposed by the Secretary of the Interior. WL-34- Prevent the spread of non-native plants, especially cheatgrass, salt cedar and Russian olive to maintain and enhance the habitat of neotropical migratory birds. Rangeland Health Standard 3- Protect against the establishment and/or spread of noxious or other weeds from intensive recreation, including the use of riding and pack animals, hiking, motorized, or other mechanized vehicles. Utah Greater Sage-grouse Approved Resource Management Plan Amendment: MA-VEG-1: In PHMA, where necessary to meet GRSG habitat objectives, treat areas to maintain and expand healthy GRSG habitat (e.g., conifer encroachment areas and annual grasslands). MA-VEG-12: In PHMA, integrated Vegetation Management will be used to control, suppress, and eradicate noxious and invasive species per BLM Handbook H-1740-2. MA-FIRE-1: In collaboration with the USFWS and relevant state agencies, complete and maintain GRSG Landscape Wildland Fire and Invasive Species Habitat Assessments to prioritize at risk habitats, and identify fuels management, preparedness, suppression and restoration priorities necessary to maintain sagebrush habitat to support interconnecting GRSG populations. These assessments and subsequent assessment updates will also be a collaborative effort to take into account other GRSG priorities identified in this plan. Appendix H describes a minimal framework example and suggested approach for this assessment. MA-LG-17: In PHMA, monitor for and treat noxious weeds and treat invasive species where needed, associated with existing range improvements. Executive Order 13112-1999: Requires federal agencies to use relevant programs and authorities to: (i) prevent the introduction of invasive species; (ii) detect and respond rapidly to and control populations of such species in a cost-effective and environmentally sound manner; (iii) monitor invasive species populations accurately and reliably; (iv) provide for restoration of native species and habitat conditions in ecosystems that have been invaded; (v) conduct research on invasive species and develop technologies to prevent introduction and provide for environmentally sound control of invasive species; and (vi) promote public education on invasive species and the means to address them; and (vii) not authorize, fund, or carry out actions that are likely to cause or promote the introduction or spread of invasive species in the United States or elsewhere unless, pursuant to guidelines that it has prescribed, the agency has determined and made public its determination that the benefits of such actions clearly outweigh the potential harm caused by invasive species. BLM Manual 9015 -- Integrated Weed Management Objectives * The BLM is vitally interested in an integrated pest management approach to the control and management of noxious Weeds. The BLM has and shall continue to remain active in developing, demonstrating, and applying the essential science, technology, and stewardship necessary to effectively manage and prevent the spread and infestation of noxious weeds. * The BLM's historical role has been reactive; the objective of this policy is to more fully integrate all BLM programs and activities into actions, which will improve the quality and ecological conditions of lands under the BLM management in the United States. * Prevent establishment and spread of new infestation by early detection, increase the general knowledge and awareness of employees, other users of the BLM lands, private landowners/operators, and State agencies about the noxious weed problems. * Reduce existing infestation levels. * Manage and contain established stands.

Fire/Fuels
Cheatgrass infestations increase fire frequency and extent. Because of the early phenology of cheatgrass (i.e. fast growing and winter and early spring growth habit), it is able to quickly invade areas that have burned and displace native perennials. This quick invasion allows the increase of cheatgrass cover resulting in amplified fire risk and the potential for larger and more frequent fires, due to to the build-up of fine fuels. This project aims to help decrease these hazardous fuels by reducing cheatgrass cover and try to control or prevent expansion of cheatgrass.
If applicable, detail how the proposed project will significantly reduce the risk of fuel loading and/or continuity of hazardous fuels including the use of fire-wise species in re-seeding operations. Describe the value of any features being protected by reducing the risk of fire. Values may include; communities at risk, permanent infrastructure, municipal watersheds, campgrounds, critical wildlife habitat, etc. Include the size of the area where fuels are being reduced and the distance from the feature(s) at risk.
*
Water Quality/Quantity
Because of the early phenology of (i.e. fast growing and winter and early spring growth habit) cheatgrass, it easily can outcompete native vegetation for moisture, nutrients, and sunlight. Cheatgrass can exploit moisture early in the season while native perennials are still dormant due to the development of extensive root systems at cold temperatures. Cheatgrass can use a large proportion of soil moisture, making the successive establishment of other desirable plant species difficult. Thus, water quantity, especially soil moisture, could be negatively affected on a site-specific scale. Studies have found that with increased fire frequency due to cheatgrass infestations, overall erosion potential increases after a wildfire, thus in the short-term water quality could be compromised until the cheatgrass can produce enough litter and root mass to hold the soils in place. In the short-term after a fire the soil is exposed and without vegetation to provide cover and roots to bind soil particles together, the soil is then more prone to water and wind erosion. With the shorter cheatgrass-fire intervals, risk of erosion increases, thus water quality may decrease in the interim on a site-specific scale.
Describe how the project has the potential to improve water quality and/or increase water quantity, both over the short and long term. Address run-off, erosion, soil infiltration, and flooding, if applicable.
*
Compliance
NEPA and archaeology clearances have been previously completed on all the project areas. Range Improvement Project (RIP) forms will be completed before the project proceeds on any SITLA areas. A Peticide Use Proposal (PUP) Form will also be completed with the BLM before any treatments occur.
Description of efforts, both completed and planned, to bring the proposed action into compliance with any and all cultural resource, NEPA, ESA, etc. requirements. If compliance is not required enter "not applicable" and explain why not it is not required.
*
Methods
Plateau herbicide will be applied aerially to the entire project areas in the fall of 2019.
Describe the actions, activities, tasks to be implemented as part of the proposed project; how these activities will be carried out, equipment to be used, when, and by whom.
*
Monitoring
Pre and post vegetation transects and photos in each treatment area will help to monitor changes in cheatgrass cover. This monitoring will allow us to determine if future herbicide treatments are needed or even potentially a seeding to help boost native perennial plant growth in the treatment areas. Some of the areas do have monitoring data from 2015 through the UDWR Range-Trend Crews.
Describe plans to monitor for project success and achievement of stated objectives. Include details on type of monitoring (vegetation, wildlife, etc.), schedule, assignments and how the results of these monitoring efforts will be reported and/or uploaded to this project page. If needed, upload detailed plans in the "attachments" section.

Partners
This project was first discussed internally through BLM fire and fuels and wildlife resources. Treatment areas were identified and cover BLM and SITLA lands. Ethan Hallows, the new SITLA Coordinator for our area was contacted and is on board with the treatments, he will be helping us process the RIPs forms to implement these treatments on SITLA lands. One of the areas on Diamond Mountain is close to some private lands. I have contacted Charlie Holtz the Sage-grouse Initiative Biologist through NRCS and he will make contact with the landowner to see if they would want to tag onto the herbicide treatment project as well through an NRCS contract. There is potential also to collaborate with the NPS, an email has been sent for potential collaboration.
List any and all partners (agencies, organizations, NGO's, private landowners) that support the proposal and/or have been contacted and included in the planning and design of the proposed project. Describe efforts to gather input and include these agencies, landowners, permitees, sportsman groups, researchers, etc. that may be interested/affected by the proposed project. Partners do not have to provide funding or in-kind services to a project to be listed.
*
Future Management
The treatment areas will be monitored after the treatment initially and then every 3-5 years post treatment, this will allow us to determine if future herbicide treatments are needed or even potentially a seeding to help boost native perennial plant growth in the treatment areas.
Detail future methods or techniques (including administrative actions) that will be implemented to help in accomplishing the stated objectives and to insure the long term success/stability of the proposed project. This may include: post-treatment grazing rest and/or management plans/changes, wildlife herd/species management plan changes, ranch plans, conservation easements or other permanent protection plans, resource management plans, forest plans, etc.
*
Sustainable Uses of Natural Resources
The project area is currently grazed, by cattle and some areas by sheep, and will continue to be grazed. The herbicide treatments will not influence the current grazing management plans. Cheatgrass infestations can affect rangeland forage for livestock and wildlife because it replaces perennial species that provide high nutrition and year-round forage. Cheatgrass can provide good nutrition during its early growth stages but cheatgrass is only palatable for a short window of time. The year-to-year forage production of cheatgrass also varies greatly. With a small window of palatability, varied forage production, and displacement of native perennial species, all these factors influenced by cheatgrass infestations can cause a significant cost in forage quantity and quality, loss of wildlife habitat, degradation of ecosystems, and cost-prohibitive restoration. Increased fire frequency can also influence recreational use of the area due to cost of rehabilitation and potentially closing off areas to recreational use due to fire recovery of the area.
Potential for the proposed action to improve quality or quantity of sustainable uses such as grazing, timber harvest, biomass utilization, recreation, etc. Grazing improvements may include actions to improve forage availability and/or distribution of livestock.
