Endangered and Threatened Wildlife and Plants; 12-Month Determination on a Petition To Revise Critical Habitat for the Mount Graham Red Squirrel

We, the U.S. Fish and Wildlife Service (Service), announce a 12-month determination on a petition to revise critical habitat for the Mount Graham red squirrel (Tamiasciurus hudsonicus grahamensis) under the Endangered Species Act of 1973, as amended (Act). The petition requests that the Service expand the subspecies' critical habitat designation to include currently occupied mixed conifer habitat and all historically occupied habitat outside the current critical habitat designation. Our 12-month determination is that we intend to assess revisions to the subspecies' critical habitat after a species status assessment and revised recovery plan for the Mount Graham red squirrel are completed.
