Endangered and Threatened Wildlife and Plants; Endangered Species Status for the Peñasco Least Chipmunk and Designation of Critical Habitat

We, the U.S. Fish and Wildlife Service (Service), list the Pe[ntilde]asco least chipmunk (Neotamias minimus atristriatus), a mammal from New Mexico, as an endangered species under the Endangered Species Act of 1973 (Act), as amended. We also designate critical habitat. In total, approximately 1,774 hectares (4,386 acres) in Lincoln County, New Mexico, fall within the boundaries of the critical habitat designation. This rule extends the protections of the Act to this species and its designated critical habitat.
