90-Day Finding on Petitions To List the Mono Basin Area Population of the Greater Sage-Grouse (Centrocercus urophasianus) as Threatened or Endangered

We, the U.S. Fish and Wildlife Service (Service), announce a 90-day finding on two petitions to list the Mono Basin area population of the greater sage-grouse (Centrocercus urophasianus) in the Bi-State area of California and Nevada as threatened or endangered under the Endangered Species Act of 1973, as amended (Act). We find that the petitions present substantial scientific or commercial information indicating that listing this population may be warranted. Therefore, with the publication of this notice, we are initiating a status review to determine if listing the Mono Basin area population of greater sage- grouse is warranted. To ensure that the status review is comprehensive, we are soliciting scientific and commercial data and other information regarding this population of the species. We will initiate a determination on critical habitat for this species if and when we initiate a listing action.
