Endangered and Threatened Wildlife and Plants; Designation of Critical Habitat for the San Bernardino Kangaroo Rat (Dipodomys merriami parvus)

We, the U.S. Fish and Wildlife Service (Service), are designating final revised critical habitat for the San Bernardino kangaroo rat (Dipodomys merriami parvus) under the Endangered Species Act of 1973, as amended (Act). Approximately 7,779 acres (ac) (3,148 hectares (ha)) of habitat in San Bernardino and Riverside Counties, California, are being designated as critical habitat for the San Bernardino kangaroo rat. This final revised designation constitutes a reduction of approximately 25,516 ac (10,326 ha) from the 2002 designation of critical habitat for the San Bernardino kangaroo rat.
