Endangered and Threatened Wildlife and Plants; Designation of Critical Habitat for Sonoyta Mud Turtle

We, the U.S. Fish and Wildlife Service (Service), propose to designate critical habitat for the Sonoyta mud turtle (Kinosternon sonoriense longifemorale) under the Endangered Species Act of 1973, as amended (Act). In total, approximately 12.28 acres (4.97 hectares) in Pima County, Arizona, located entirely within Organ Pipe Cactus National Monument, fall within the boundaries of the proposed critical habitat designation. If we finalize this rule as proposed, it would extend the Act's protections to this subspecies' critical habitat. We also announce the availability of a draft economic analysis of the proposed designation of critical habitat for the Sonoyta mud turtle.
