This Report provides a strategic approach for conservation of sagebrush ecosystems and Greater SageGrouse (sage-grouse) that focuses specifically on habitat threats caused by invasive annual grasses and altered fire regimes. It uses information on factors that influence (1) sagebrush ecosystem resilience to disturbance and resistance to invasive annual grasses and (2) distribution, relative abundance, and persistence of sage-grouse populations to develop management strategies at both landscape and site scales. A sage-grouse habitat matrix links relative resilience and resistance of sagebrush ecosystems with sage-grouse habitat requirements for landscape cover of sagebrush to help decision makers assess risks and...
Fishes of the Upper Colorado River Basin have one of the highest levels of endemism in the United States. The range and abundance of these fish has declined over the last century and continues to decline as a result of legacy impacts from past management practices, current water management, interactions with non-natives, and other impacts. Seven of these fish are considered imperiled by the American Fisheries Society and four are listed as endangered by the U.S. Fish and Wildlife Service. We applied a complementarity-based approach to develop priority ranks (0 – 1; low to high) for catchments in the Upper Colorado River Basin. We used methods and a framework that we had previously developed for the Lower Colorado...

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
