The Greater Sage-Grouse is North America's largest grouse, a characteristic feature of habitats dominated by big sagebrush ( Artemisia tridentata) in western North America. The first written accounts of this species were based on observations by the Lewis and Clark expedition in 1805, when the species was widespread in the West; its distribution and population densities have been greatly reduced because of loss of habitat to cultivation, burning, and overgrazing. Most populations face problems that may impact their long-term survival, problems that continue despite a century of conservation concern and management efforts.
