Endangered and Threatened Wildlife and Plants; Revised Critical Habitat for Santa Ana Sucker

Résumé

We, the U.S. Fish and Wildlife Service (Service), designate critical habitat for Santa Ana sucker (Catostomus santaanae) under the Endangered Species Act of 1973, as amended. In total, approximately 9,331 acres (3,776 hectares) of habitat in the Santa Ana River in San Bernardino, Riverside, and Orange Counties and the San Gabriel River and Big Tujunga Creek in Los Angeles County in southern California fall within the boundaries of the critical habitat designation. This final revised designation constitutes an overall increase of approximately 1,026 acres (415 hectares) from the 2005 designation of critical habitat for Santa Ana sucker.
