Sage-grouse & Sagebrush Ecosystem
Sage-Grouse
Despite being one of the most well-studied upland game birds in North America, key knowledge gaps persist in the understanding of sage-grouse biology. USGS scientists are working to address these knowledge gaps in key areas including the development of population models that incorporate information about the complexities of the biological processes and dynamic habitats, improving the understanding the landscape attributes at facilitate connectivity between populations, and refinement of monitoring strategies and creation of tools to improve information about sage-grouse population characteristics.

Greater Sage-Grouse Population Ecology
Greater Sage-grouse are iconic birds found only in the Great Basin of the western U.S. Known for their showy courting displays, sage-grouse rely on native sagebrush habitat to shelter their young. Dr. Pete Coates is providing resource managers with the tools and information they need to conserve sage-grouse as invasive plants, evolving wildfire patterns, and energy development change the Great...
Incorporating Genetic Data into Spatially-explicit Population Viability Models for Gunnison Sage-grouse
This goal of this study is to develop a spatially explicit habitat-population modeling framework to assess the viability of Gunnison Sage-grouse and each of the seven populations (Gunnison Basin and six satellite populations).
Tools for Managing and Monitoring Sage Grouse
To better understand how land-use changes are affecting greater sage-grouse (Centrocercus urophasianus), FORT is collaborating with USGS centers FRESC, GECSC, WERC, and EROS; the BLM; Colorado State University; and the WLCI to develop information and tools for managing and monitoring grouse.
Conservation Genomics
Conservation genomics is a new field of science that applies novel whole-genome sequencing technology to problems in conservation biology. Rapidly advancing molecular technologies are revolutionizing wildlife ecology, greatly expanding our understanding of wildlife and their interactions with the environment. In the same way that molecular tools such as microsatellites revolutionized wildlife...
Population Genetics
Population genetics is an area of research that examines the distribution of genetic variation and levels of genetic diversity within and between populations. This information provides insights into the level of connectedness of populations throughout a species’ range and can be used to identify unique populations or those with low levels of genetic diversity.
Population Models
Population models can incorporate genetic data to assess potential impacts of different management strategies on connectivity, effective population size, and genetic diversity.
Landscape Genetics of Sage Grouse
Greater and Gunnison sage-grouse populations are species considered for listing under the Endangered Species Act of 1973. Loss and fragmentation of sagebrush habitats are among the primary causes of decline in these species. A fundamental need for species conservation is to identify and subsequently maintain a set of connected populations. Landscape genetics combines the fields of population...
