Effects of Treatments on the Connectivity and Fragmentation of Wildlife Populations across the Great Basin
FY2016This project will evaluate the effects of vegetation treatments on population connectivity, genetic diversity and gene flow of wildlife species across the full extent of the Great Basin LCC. The recently approved BLM and Forest Service Land Use Plan Amendments will implement millions of acres of treatments in support of greater sage-grouse conservation. It is essential to evaluate the potential benefits and risks of these treatments on the connectivity and fragmentation of the landscape for multiple non-target species. We will use a dynamic landscape model to simulate fire and treatments, allowing each to vary by type (e.g., juniper removal, prescribed fire), extent, and influence on vegetation and fuels....
Measuring the Regional Impacts of Pinyon and Juniper Removal on Insect, Bat, and Reptile Communities
FY2016Monitor the diversity and abundance of winged insects (including Lepidoptera, Hymenoptera, Coleoptera, Diptera, and Hemiptera), which include many key insect pollinators, using an array of passive and active trapping methods. Monitor bat diversity and relative densities using passive acoustic monitoring stations (we will use full-spectrum passive recording units). Monitor diversity and abundance of reptiles (lizards and snakes), using trap arrays (pitfall and coverboard) and time-constrained visual encounter surveys. Create empirically supported models of reptile, bat, and insect diversity and abundance as a function of vegetation structure and composition, microclimate, and other environmental variables,...
Understanding Effects of Juniper Removal in Support of Greater Sage-grouse on Sagebrush Steppe Bird and Small Mammal Communities at Multiple Spatial Scales
FY2015Study the wildlife impacts of the Bruneau-Owyhee Sage-grouse Habitat (BOSH) project. (The removal of approximately 600,000 acres of western juniper across a landscape of ~1.5 million acres over the next generation in an attempt to reverse sage-grouse habitat loss caused by woodland encroachment.) Monitor the effects of the BOSH project on wildlife by understanding effects of habitat treatments conducted in support of greater sage-grouse on other wildlife critical to inform federal management plans. Collect and analyze data on wildlife and habitat responses at multiple control levels and in predetermined areas. Methods are described in the full proposal submitted and collection of data will occur for at least...
