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....

The results of this proposed project would provide the first comprehensive identification of fisher distribution in the northern Rocky Mountains, which may serve as a baseline for identifying population trends and changes in distribution over time.A species distribution model will be constructed, using field data collected to date, that relates fisher presence observations to environmental variables (i.e., spring snow cover, minimum spring temperatures, annual rainfall, topographic position, elevation, and others). These environmental predictors will provide an indication of the contemporary distribution and environmental requirements of the species in the northern Rocky Mountains. Down-scaled global climate models...

Our 2010 statewide connectivity analysis identified broad-scale priority areas for connectivity conservation. More detailed, finer-scale analyses will give land managers the information they need to begin prioritizing and implementing conservation actions. The Columbia Plateau (Appendix A, Fig. 1) was selected for the first ecoregional-scale analysis for two reasons. First, several climate models suggest that the Columbia Plateau Ecoregion in Washington is likely to be a stronghold of shrubsteppe ecosystems under climate change. Second, despite the high level of habitat loss and fragmentation in the ecoregion, our statewide analysis identified previously undocumented patterns and opportunities for multiple-species...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
