Need for Project
We will seek to develop and validate models that evaluate the effects of conifer removal treatments on mitigating resistance to sage-grouse movements and habitat-use in an anthropogenic-altered landscape that is managed by multiple jurisdictions. We will also seek to validate the effect of mechanical conifer treatments of sage-grouse population stability and growth. This research will provide land managers with added information regarding the scale and placement of mechanical treatments to mitigate the potential effects anthropogenic disturbances on sage-grouse populations in conifer-encroached areas in northwestern Utah.
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. What effects have the scale and placement of mechanical conifer removal treatments completed in the Box Elder SGMA had on sage-grouse vital rates and population trends? 2. What effects have scale and placement of mechanical conifer removal treatments completed in the Box Elder SGMA has had on mitigating resistance to sage-grouse movements and habitat-use in an anthropogenic-altered landscape? 3. What scale of mechanical conifer removal treatments is desired to mitigate resistance to sage-grouse movements and habitat-use in an anthropogenic-altered landscape?
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?)
Previous research has documented sage-grouse avoidance of conifer cover (Doherty et al. 2008), negative effects of conifer cover on lek counts (Baruch-Mordo et al. 2013), and increased sage-grouse use of sagebrush landscapes following conifer removal in anthropogenic-altered landscapes (Frey et al. 2013, Cook 2015)0. Cook et al. (2016 [in review]) reported sage-grouse use was positively associated with irrigated pasture and alfalfa (Medicago sativa) hay within 0.6 mile (1 km) and negatively associated with conifer canopy cover within 0.3 mile (500 m) of treatments completed in the Box Elder Sage-grouse Management Area (SGMA) in Utah. Additionally, percent cover of mesic habitats and sagebrush canopy were higher within 0.6 mile (1 km) of treatments where sage-grouse were detected. Sandford et al. (2015) documented sage-grouse nesting in an active conifer mastication treatment in the Box Elder SGMA. These studies validated that the placement of mechanical conifer treatments adjacent to occupied sage-grouse habitats will enhance sage-grouse seasonal use and nesting (Frey et al. 2013, Cook 2015, Sandford et al. 2015).
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
The Natural Resources Conservation Service (NRCS), through its Sage-grouse Initiative (www.sagegrouseinitiative.com), has provided cost-share to landowners to mechanically remove or reduce thousands of acres of conifer woodlands on private lands in the western U.S. Similar projects have been implemented range wide on Bureau of Land Management (BLM) and U.S. Forest Service (USFS) administered lands. In Utah alone, conifers have been removed from > 500,000 ac (200,000 ha) of sagebrush landscapes since 2006 under the Utah Department of Natural Resources (UDNR) Watershed Restoration Initiative (WRI; UDNR 2014). Mechanical conifer reduction projects are relatively low cost on a per acre basis, and may have potential for increasing usable habitat for sage-grouse (Baruch-Mordo et al. 2013, Dahlgren et al. 2016a, Cook et al. 2016 [in review]), and may also mitigate the impacts of previous anthropogenic development on sage-grouse seasonal movements (Beck et al. 2006, Johnson et al. 2011, Knick et al. 2013, Messmer 2013). In addition, in June 2015, the BLM published the Sage-grouse Habitat Assessment Framework (HAF) -- Technical Reference 6701 (Stiver et al. 2015). The HAF provides the BLM with a multiple-scale, sage-grouse habitat assessment tool that can be integrated into the landscape monitoring approach that will be used to implement the BLM Resource Management Plan (RMP) amendments (BLM 2015). The HAF establishes indicators to determine the status of sage-grouse habitat needs at multiple scales for seasonal habitats. This work will provide data to support the HAF.

Water Quality/Quantity
Cook et al. (2016 [in review]) reported sage-grouse use was positively associated with irrigated pasture and alfalfa (Medicago sativa) hay within 0.6 mile (1 km) and negatively associated with conifer canopy cover within 0.3 mile (500 m) of treatments completed in the Box Elder Sage-grouse Management Area (SGMA) in Utah. Additionally, percent cover of mesic habitats and sagebrush canopy were higher within 0.6 mile (1 km) of treatments where sage-grouse were detected. We will document any changes in mesic site in the confier removal areas.

Methods
In 2015, we began to deploy geographic positioning system (GPS) transmitters on female sage-grouse in the Box Elder SGMA following protocols described by Connelly et al. (2003). To date we have deployed eight backpack style GPS transmitters (Microwave Telemetry, Inc. 22g PTT-100 Solar Argos GPS Transmitter) on female sage-grouse. In the spring of 2016, we will deploy 12 additional GPS transmitters in areas where mechanical conifer removal projects have been completed. Up to 30 female sage-grouse will also be fitted with a 18-g necklace style very high frequency (VHF) radio transmitters in the same areas (Advanced Telemetry Systems, Insanti, MN and American Wildlife Enterprises, Monticello, FL). The combination of GPS and VHF radio-transmitters will also allow us to evaluate if the type of transmitter deployed may affect vital rates. Caudill et al. (2014) reported sage-grouse fitted with back-mounted radio-transmitters had lower survival rates than birds fitted with necklace-style radio-collars. Every sage-grouse captured is weighed, sexed, aged, evaluated for general health, and receives a numbered leg band. Every capture site is recorded (UTM, 12N, NAD 1983). Birds are handled and released at the capture site.
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
The radio-marked sage-grouse will be located a minimum of twice a week during nesting and brood rearing season. Nest will be visually confirmed, and then monitored 2-3 times per week from the furthest distance that observer can confirm the female's location without risk of disturbance. After hatching, females with broods are located 2-3 times per week. Broods are flushed 50 days post-hatch to determine brood success and approximate brood size. The presence of a minimum of one chick per hen is classified as brood success. In fall and winter months, GPS radio-marked sage-grouse will be re-located weekly via Movement (Movebank Animal Tracking Data 2015) and VHF radio-marked sage-grouse will be re-located bi-monthly via fixed-wing aircraft to estimate survival and record habitat use. Vegetation surveys will be conducted at all nest sites, every other brood site, and one random site for every other measure brood site. These vegetation surveys provide information about cover and forage plant preferences in utilized areas (Connelly et al. 2003). Each survey consists of four transects placed in cardinal direction from the used site. Transect are 15m and 10m at nest and brood sites, respectively. We will record GPS locations at every sage-grouse use and observation site. All locations are overlaid on remotely sensed conifer map cover map to determine thresholds of use based on conifer cover (Stankey and Germiono 2008, Fedy et al. 2014)

Future Management
We will use a Resource Selection Function to determine whether sage-grouse are utilizing one habitat type (sagebrush, phase I, II, III juniper invaded areas, or juniper removal areas) over another and then investigate if these behaviors are different survival rates and movement patterns (Gilles et al. 2006, Sandford et al, 2016[in review]). The location data collected from radio-marked female sage-grouse will be used to conduct a landscape analysis and logistic regression to evaluate a range of resistance models in terms of their ability to depict and predict empirical patterns of lek occupancy and individual sage-grouse habitat-use based on the type, age, scale and location of mechanical conifer removal treatments (Shirk et al. 2015).
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.
