Need for Project
This phase of the project proposes to address conifer encroachment on 10,404 acres of sagebrush capable landscapes. This is phase two of a 40,000 acre focus area on Mytoge and Tidwell Mountains. All of which falls into the Parker Mountain-Emery Sage Grouse Management Area. The proposed treatment areas have active winter, nesting and brood rearing habitat. This proposal directly maintains and increases sage-grouse habitat through addressing the threat of conifer expansion. In order to address this concern and maintain persistent large open sagebrush landscapes, encroaching conifers in phase I and early phase II will be removed. Persistent woodlands will be retained. Lop and scatter will occur where appropriate for the density of encroaching conifers (9,404 acres). Mastication will occur where machine accessibility exists and where bullhog treatments in early phase II can reduce per-acre lop and scatter costs (1,000 acres).
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
1) Secure existing landscape scale sagebrush habitat for sage-grouse. 2) Create/expand sagebrush habitat for sage-grouse that could be occupied immediately after treatment. 3) Mitigate the threat of conifer expansion into active sage-grouse habitat. 4) Increase available moisture for residual plant species by removing competition from trees. 5) Reduce crown fire potential and fuel loading by decreasing pinyon, juniper, and other conifer cover to less than 5% immediately post treatment.
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?)
Conifer encroachment has been identified as one of the primary threats to sage-grouse populations in Utah by the Forest Service, Fish and Wildlife Service, and the State of Utah. Reducing conifer encroachment addresses, either directly or indirectly, all four of the key sage-grouse threats identified by the Greater Sage-grouse (Centrocercus urophasianus) Conservation Objectives Final Report (February 2013) for the Greater Parker Mountain sage-grouse population. For convenience, these threats are listed below: 1) Loss or degradation of habitat (primarily due to vegetation succession) 2) Conversion of habitat (sagebrush to pinyon-juniper or cheatgrass at the lower elevations) 3) Increased risk of predation because of expansion of, or changes in, the native predator community in response to anthropogenic factors, and 4) Habitat fragmentation from loss or degradation of habitat that results in a loss of sage-grouse habitat connectivity. This project will address conifer encroachment while in early phases, decreasing the risk of sage-grouse nest and brood mortality and lowering the need for seeding the area post-treatment.
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.

Fire/Fuels
In 2015, the State of Utah's Division of Forestry, Fire and State Lands brought together landowners, country officials, and land management agency representatives to determine priority areas for Sevier County. Fishlake Basin and the surrounding watersheds were determined to be the second highest priority treatment area for Sevier County. Private properties with residential developments exist within three miles of the proposed treatment area. The Wildfire Risk Index for the proposed project area ranges from very high to very very low. Maintaining sagebrush habitat should moderate expected flame length. This project continues to build on over 600 acres to the south of the project area that has received dixie harrow treatment, breaking up the continuity of mature fuels and limiting the ability of wildfire to spread into the project area.
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 juniper are prolific water users; they readily out-compete understory species which eventually die off. Removing juniper, pinyon, and other encroaching conifers is critical for restoring sagebrush habitat and ecosystem resilience because of the water available to other species once they are gone. This is especially the case when reducing junipers at a landscape scale. Waterbodies that will benefit from project activities and occur within the project area include UM Creek, the Fremont River, Forsyth Reservoir, Lower UM Creek, and Mill Meadow Reservoir. These waterbodies receive flow/runoff from the project areas and are covered by the Fremont River Watershed Water Quality Management Plan (Fremont WQMP). These waterbodies also have requirements associated Total Maximum Daily Load (TMDL). The Fremont WQMP was created due to concerns (or impairment) of water sources in the upper Fremont River basin, in part due to phosphorus loading which can be increased by sediment that enters the water. Total phosphorus (TP) is a pollutant of concern, and low Dissolved Oxygen (DO) is a parameter of concern in Forsyth Reservoir. TP is a pollutant of concern for Mill Meadow Reservoir. Low DO in Lower UM Creek is also listed as a parameter of concern (Fremont WQMP 2002, attached in images/documents). Project activities would regenerate improved understory conditions, grass, forbs, and shrubs which should improve water quality by leading to less generation of sediment during overland flow events and thereby delivering less sediment to riparian areas, rivers, and subsequent reservoirs. Reducing sediment can decrease pollutants in these impaired waterbodies by reducing phosphorus loading associated with sediment mobilization during such flow events. Additionally, vegetation treatments would be designed to reduce the risk of severe wildfire and all of the associated undesirable water quality effects.
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
The Mytoge Tidwell Sage-Grouse Habitat Improvement Project CE and archeological clearance were completed in spring 2017.
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
Lop and scatter will occur on 9,404 acres of phase I and early phase II juniper encroached sagebrush steppe habitat All persistent woodlands will be retained. All lop and scatter work will be contracted through UDWR. All cut trees will be scattered to below surrounding sagebrush height. Mastication will occur on 1,000 acres using USFS equipment and employees.
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
Repeat photo points and range site survey locations consisting of nested frequency sites recording vegetation and percent cover already exist within the proposed project area. Vegetation surveys will occur following treatment and five years after treatment. These tools for assessing potential for conifer encroachment and invasive plant establishment, as well as a qualitative site condition assessment, will be completed in accordance with existing monitoring protocols. Additionally, active sage-grouse leks within or adjacent to the project area will continue to be monitored annually in the spring by the UDWR with the help of Parker Mountain Adaptive Resource (PARM) local working group, to determine population trends and possible relationship to project implementation. This will include using five sage grouse radio collars to document movement of sage grouse within the Dog Flat Lek, located north of Loa, Utah on the Mytoge Mountain area. These five compliment the previous six sage grouse collared installed last spring within the first phase of the Mytoge Mountain project. These collars would be tracked by DWR's Jim Lamb and Utah State University. This monitoring aims to assist UDWR's Migration Initiative Study and the request for radio collars is supported by the local PARM Working Group and Dave Dahlgren of USU Extension.
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
The USFS proposes this project with the support and coordination of the Parker Mountain Adaptive Resource Management Local Working Group. Group members include representatives from Utah State University, Bureau of Land Management, Natural Resource Conservation Service, State of Utah Division of Forestry, Fire & State Lands, Division of Wildlife Resources, and USU extension. The Mytoge-Tidwell Sage Grouse Habitat Improvement Project received supportive letters in the scoping process from DWR, Sevier County Commission, Utah Farm Bureau Federation, and Fremont River Conservation district. USFS hosted a tour of the focus area and proposed treatment location on July 27, 2016. Although the proposed project is on USFS, BLM is interested in pursuing similar treatments adjacent to the project area. Adjacent private land is steeply sloped, contains minimal pinyon and juniper invasion, and is largely near reservoirs. The project is bordered by SITLA and BLM land in the southwest portion of the project area.
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
This area will be maintained as sagebrush habitat. Potential threats include noxious weed invasion, cross-country OHV use, and reinvasion from conifers. Periodic visual inspection, photo points, and vegetation monitoring will occur to assess current conditions and track trends over time. The longevity of the treatment will be maintained by slashing young conifers that establish within the project area. Slashing could occur in 10 and 15-year intervals post-treatment.
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
Where conifers dominate, they outcompete understory vegetation for water and nutrients. Over time, these understory species become less productive and vigorous and eventually die out. Removing juniper, pinyon, and associated species releases understory grasses and forbs from competition, which increases plant vigor and rangeland productivity. These treatments will increase forage value within the UM, Tidwell, Solomon, and Thousand Lake allotments.
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.
