    About the Program

    The Endangered Species Recovery Program is a cooperative research program on biodiversity conservation in central California, administered by California State University, Stanislaus.

    The program was established in August 1992 at the request and with the support of the U.S. Fish and Wildlife Service and the Bureau of Reclamation, under the direction of Dr. Dan Williams at CSU Stanislaus. Over the past decade, ESRP has grown into a cooperative research program working with local, State, and Federal agencies, non-governmental organizations, corporations, and private land owners.

    ESRP is composed of about 18 biologists, students, and support staff, several research associates, and numerous collaborators in government and universities worldwide whose combined expertise and contributions are integral to the recovery of threatened and endangered species in Central California. ESRP biologists are based in Fresno, Turlock, Bakersfield, and the Bay Area.

    Mission Statement

    The Endangered Species Recovery Program's mission is to facilitate endangered species recovery and resolve conservation conflicts through scientifically based recovery planning and implementation.


    The central elements in the recovery of endangered and threatened species are: identifying the biological processes critical to achieving self-sustaining populations of jeopardized species and their ecosystems; developing sound species recovery and natural community management prescriptions; and identifying the social interests and entities that must be reconciled and work together in implementing recovery strategies. Such a recovery process necessarily implies the integration of all planning and implementation actions within a broadly inclusive public-private partnership to achieve a product that is environmentally sound, economically feasible, and socially equitable.
