USGS scientists are using a time-varying approach to monitor and predict recovery of sagebrush ecosystems following disturbance.

USGS scientists are evaluating the use of quantile regression to develop models of sage-grouse population changes across the United States.

USGS led an interagency team of Federal and State agency biologists to develop a report that synthesizes greater sage-grouse scientific literature.

The USGS, the BLM, the FWS, and the Western Association of Fish and Wildlife Agencies have developed of a new DOI-funded effort, known as SageDAT.

The USGS is developing science and decision support tools to inform policy and management decisions about various aspects of the energy development life cycle.

USGS scientists and colleagues have designed a hierarchical monitoring framework for greater sage-grouse in Nevada, Wyoming, and northeastern California that will provide land managers with a monitoring and detection system to identify sage-grouse breeding locations (known as leks), clusters of leks, and populations where intervention may be necessary to sustain populations and to evaluate...

Environmental DNA (eDNA) is organismal DNA that can be found in the environment. Environmental DNA originates from cellular material shed by organisms (via skin, excrement, etc.) into aquatic or terrestrial environments that can be sampled and monitored using new molecular methods. Such methodology is important for the early detection of invasive species as well as the detection of rare and...

Increased wildfire-induced loss of sagebrush in North American shrublands are outpacing natural recovery and leading to substantial habitat loss for sagebrush-obligate species like sage-grouse. The products and information developed for this project will help restoration practitioners, biologists, and land managers evaluate the efficacy of sagebrush restoration approaches as well as their ability...

USGS and university researchers analyzed changes in male sage-grouse lek counts in Wyoming from 1984 through 2008, measuring disturbance owing to oil and gas development.

USGS scientists and partners investigated sage-grouse population trends in Wyoming and at multiple spatial scales.

US Geological Survey scientists and collaborators are using genetic information contained in sage-grouse feathers collected at leks to define the rangewide network of breeding populations.
