Western Ecological Research Center (WERC)

The Western Ecological Research Center (WERC) is a USGS Ecosystems Mission Area operation serving primarily California and Nevada. WERC scientists work closely with Federal, State, academic, and other collaborators to address a diverse array of high-profile topics. Topics include research on effects of wildfire, sea level rise, drought, energy development and more on federal Trust species.

Greater sage-grouse habitat of Nevada and northeastern California—Integrating space use, habitat selection, and survival indices to guide areas for habitat management

Executive SummaryGreater sage-grouse populations (Centrocercus urophasianus; hereafter sage-grouse) are threatened by a suite of disturbances and anthropogenic factors that have contributed to a net loss of sagebrush-dominant shrub cover in recent decades. Declines in sage-grouse populations are largely linked to habitat loss across their range. A key component of conservation and land use plannin

Vulnerability to sea-level rise varies among estuaries and habitat types: Lessons learned from a network of surface elevation tables in Puget Sound

Estuarine systems that provide valuable ecosystem services to society and important foraging and rearing habitat for fish and wildlife species continue to undergo degradation. In Puget Sound, WA, as much as 70–80% of historic estuarine habitat has been lost to anthropogenic development, and continued losses are expected through the end of the twenty-first century due to rising sea levels. To evalu

Allochthonous marsh subsidies enhances food web productivity in an estuary and its surrounding ecosystem mosaic

Terrestrial organic matter is believed to play an important role in promoting resilient estuarine food webs, but the inherent interconnectivity of estuarine systems often obscures the origins and importance of these terrestrial inputs. To determine the relative contributions of terrestrial (allochthonous) and aquatic (autochthonous) organic matter to the estuarine food web, we analyzed carbon, nit

Estimating spatial variation in greater sage-grouse lek buffers using seasonal space use models

Greater sage-grouse ( Centrocercus urophasianus ) management relies on the identification and protection of core habitat for the species. Core areas are often centered on leks where the potential impacts of anthropogenic development and other disturbances can be evaluated based on buffer distances around active leks. While buffer distances have been quantified for some regions, sage-grouse space...

A user-friendly decision support tool for monitoring and managing greater sage-grouse populations

Researchers within the U.S. Geological Survey (USGS) and Colorado State University (CSU) developed a hierarchical population monitoring framework for managing greater sage-grouse ( Centrocercus urophasianus ) populations and the sagebrush ecosystems that they depend upon for survival and reproduction. This hierarchical population monitoring strategy now serves as a foundation for future...

Hierarchical Population Monitoring Framework for Greater Sage-Grouse

Greater sage-grouse ( Centrocercus urophasianus ) are at the center of state and national land use policies largely because of their unique life-history traits as an ecological indicator for health of sagebrush ecosystems.
