Bi-State Sage-grouse are a geographically isolated and genetically distinct population of Greater Sage-grouse, found along the California-Nevada border in the southwestern extent of the species’ range. Known as a Distinct Population Segment, these birds are evaluated independently from other sage-grouse populations under the U.S. Fish and Wildlife Service’s (USFWS) Endangered Species Act (ESA). Because the Bi-State population is small and disconnected from other sage-grouse populations, they may be more susceptible to population declines—or even extinction. As a result, a concerted, collaborative effort to understand this population’s trend, and to conserve Bi-State numbers, has been underway for nearly twenty years.
