Designation of Critical Habitat for the Sonoma County Distinct Population Segment of the California Tiger Salamander; Final Rule

We, the U.S. Fish and Wildlife Service (Service), designate and exclude approximately 17,418 acres (ac) (7,049 hectares (ha)) of critical habitat for the Sonoma County distinct population segment of the California tiger salamander (Ambystoma californiense) pursuant to the Endangered Species Act of 1973, as amended (Act). We are excluding all critical habitat based on interim conservation strategies and measures being implemented by those local governing agencies with land use authority over the area and also as a result of economic exclusions authorized under section 4(b)(2) of the Act. Therefore, no critical habitat is being designated for the Sonoma County distinct population segment of the California tiger salamander in Sonoma County, California.
