The U.S. Fish and Wildlife Service today announced it is proposing to revise its designation of critical habitat under the Endangered Species Act for the endangered San Bernardino kangaroo rat. Approximately 9,079 acres of federal, local, and privately owned land in portions of Riverside and San Bernardino counties, California are included in the revised critical habitat proposal.
The San Bernardino kangaroo rat occurs in scattered, isolated patches of alluvial (loose, soft sand) sage-scrub habitat in portions of San Bernardino and Riverside counties in southern California. Three separate areas within the range of the species are being proposed as critical habitat. The three units include portions of the Santa Ana River Wash; Lytle and Cajon Creek Washes in San Bernardino County; and the San Jacinto River Wash in Riverside County.
Of the 9,079 acres included in the revised critical habitat proposal, the Service is considering excluding 2,544 acres from the final designation because they are already covered by an existing management plan that benefits the San Bernardino kangaroo rat. Lands proposed for exclusion from the final designation include areas within the Woolly-Star Preserve Area Management Plan, the Former Norton Air Force Base Conservation Management Plan, the Cajon Creek Habitat Conservation Management Area Habitat Enhancement and Management Plan, and areas covered by the Western Riverside County Multiple Species Habitat Conservation Plan.
As a result of a lawsuit, the Service designated critical habitat for the San Bernardino kangaroo rat in 2002. Approximately 33,295 acres of land in Riverside and San Bernardino counties were designated as critical habitat for the species.
Following publication of the 2002 final rule, a second lawsuit was filed against the Service by the Pacific Legal Foundation challenging the adequacy of the economic analysis, and delineation and justification of critical habitat for the San Bernardino kangaroo rat and 26 other species.
Today's announcement is in response to a settlement agreement that required the Service to complete a revised critical habitat proposal for the San Bernardino kangaroo rat by June 1, 2007.
The kangaroo rat gets its name from large hind legs and feet that aid the tiny mammal when it jumps. The San Bernardino kangaroo rat is one of several subspecies of Merriam's kangaroo rat. It is considerably darker and smaller than other members of the subspecies. Kangaroo rats are only found in desert regions of the southwestern United States and northwestern Mexico.
The San Bernardino kangaroo rat is threatened by continued loss, degradation, and fragmentation of its habitat due to sand and gravel mining operations, flood control projects, and urban development. Three of the largest blocks of remaining habitat for the species are actively mined for sand and gravel, and mining activity in these areas is expected to increase.
