## Abstract

We, the U.S. Fish and Wildlife Service, revise the critical habitat for the Riverside fairy shrimp under the Endangered Species Act of 1973, as amended. The previous critical habitat consisted of land in four units in Ventura, Orange, and San Diego Counties, California. We now designate land in three units in Ventura, Orange, and San Diego Counties, California, for a total of approximately 1,724 ac (698 ha), which represents critical habitat for this species. Areas in Riverside County are excluded from critical habitat in this final revised rule.
