The greater sage-grouse was once widespread within sagebrush-grassland ecosystems of western North America, but populations declined substantially during the 20th century. Given the ubiquity of livestock grazing within sage-grouse habitat and the lack of rigorous scientific data to inform the debate regarding the effects of grazing on sage-grouse populations, we are conducting a 10-year research project to experimentally evaluate the effects of cattle grazing on demographic traits and habitat characteristics of greater sage-grouse. The project is a collaboration between USGS Idaho Cooperative Fish & Wildlife Research Unit, University of Idaho, Bureau of Land Management, U.S. Fish and Wildlife Service, Public Lands Council, and Idaho Department of Fish and Game. The results will help guide management actions (and inform policy and litigation decisions) throughout the western United States.
