Endangered and Threatened Wildlife and Plants; Designation of Critical Habitat for the Perdido Key Beach Mouse, Choctawhatchee Beach Mouse, and St. Andrew Beach Mouse

We, the U.S. Fish and Wildlife Service (Service), are revising critical habitat for the Perdido Key beach mouse (Peromyscus polionotus trissyllepsis) and Choctawhatchee beach mouse (Peromyscus polionotus allophrys) and designating critical habitat for the St. Andrew beach mouse (Peromyscus polionotus peninsularis) under the Endangered Species Act of 1973, as amended (Act). In total, approximately 6,193 acres (ac) (2,506 hectares (ha)) are being designated as critical habitat for the three subspecies. This action adds approximately 135 ac (44 ha) to the amount of currently designated critical habitat for the Perdido Key beach mouse and 1,629 ac (659 ha) to the area designated for the Choctawhatchee beach mouse. The critical habitat is located in Baldwin County, Alabama; and Escambia, Okaloosa, Walton, Bay, and Gulf Counties, Florida.
