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, Carson City, Mineral, 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?

Bi-State sage-grouse are currently listed as proposed threatened under the Endangered Species Act and 1.3 million acres of habitat is listed as proposed designated critical habitat. A new listing decision will be published in the Federal Register on October 1, 2019. Click here to learn more about the listing history of Bi-State sage-grouse.
