Endangered and Threatened Wildlife and Plants; Revised Critical Habitat for the Preble's Meadow Jumping Mouse (Zapus hudsonius preblei) in Colorado

요약

We, the U.S. Fish and Wildlife Service (Service), propose to revise designated critical habitat for the Preble's meadow jumping mouse (Zapus hudsonius preblei) in Colorado, where it is listed as threatened in a significant portion of the range (SPR) under the Endangered Species Act of 1973, as amended (Act). The proposed revised critical habitat is located in Boulder, Broomfield, Douglas, El Paso, Jefferson, Larimer and Teller Counties in Colorado. Approximately 418 miles (mi) (674 kilometers (km)) of rivers and streams and 39,142 acres (ac) (15,840 hectares (ha)) fall within the boundaries of the proposed revised designation. The proposed revised designation would therefore add 184 mi (298 km) of rivers and streams and 18,462 ac (7,472 ha) to the existing critical habitat designation of 234 mi (376 km) and 20,680 ac (8,368 ha).
