Bi-State Area Information

Bi-State PMUs

Where is the Bi-State?

The Bi-State area occurs along the California-Nevada border, it covers an area approximately 170-miles long and up to 60 miles wide. It includes portions of five counties in western Nevada: Douglas, Lyon, Mineral, Carson City, and Esmeralda; and three counties in eastern California: Alpine, Mono, and Inyo. Land ownership is composed of federal, state, county, tribal and private lands.

What is the Bi-State Sage-Grouse?

The Bi-State sage-grouse (BSSG) is a genetically unique meta-population of greater sage-grouse, known as a distinct population segment (DPS), that lives in the far southwestern limit of the species’ range in the Bi-State area. This genetic distinction may be the result of natural geologic events and subsequent long-term geographic isolation based on prevailing physiographic and habitat conditions.

What are the threats to Bi-State sage-grouse populations and its habitats?

The primary threats to the BSSG and its habitat vary by Population Management Unit (PMU) (See table for threats by PMU). However, wildfire and conifer encroachment are the highest threats across the entire Bi-State.

What is the current status of Bi-State sage-grouse?

The U.S. Fish and Wildlife Service withdrew a 2013 proposed rule to list the Bi-State distinct population segment of greater sage-grouse as threatened under the Endangered Species Act. The Service concluded that future conservation measures are highly certain to be effective in ameliorating the threats currently impacting the Bi-State DPS. Therefore, they found the Bi-State DPS is not in danger of becoming extinct nor endangered throughout all or a significant portion of its range. The Service acknowledges and commends the commitment of the Bi-State Local Area Working Group in implementing numerous conservation actions to improve habitat conditions and to ensure Bi-State sage-grouse population success. Click here to learn more about the listing history of Bi-State sage-grouse.
