Endangered and Threatened Wildlife and Plants; Listing and Designation of Critical Habitat for the Chiricahua Leopard Frog

We, the U.S. Fish and Wildlife Service (Service), are designating critical habitat for the Chiricahua leopard frog (Lithobates chiricahuensis) under the Endangered Species Act of 1973, as amended (Act). In total, we are designating approximately 10,346 acres (4,187 hectares) as critical habitat for the Chiricahua leopard frog in Apache, Cochise, Gila, Graham, Greenlee, Pima, Santa Cruz, and Yavapai Counties, Arizona; and Catron, Grant, Hidalgo, Sierra, and Socorro Counties, New Mexico. In addition, because of a taxonomic revision of the Chiricahua leopard frog, we reassessed the status of and threats to the currently described species Lithobates chiricahuensis and are listing the currently described species as threatened.
