    Endangered Species Project

    Lead California Department of Pesticide Regulation [DPR]
    Description In California, DPR has been studying endangered species protection issues with federal funding since 1988. DPR activities include mapping sites occupied by federally listed species, evaluating pesticide exposure risks to inhabited sites, classifying risk and developing protection strategies to minimize risk as needed. There are currently 359 federally listed species in California including federally protected endangered and threatened species, proposed endangered, proposed threatened and Category 1 candidate species (that await only administrative processes to become protected species). Collectively, the federally listed species may occupy about 16 million acres, or about 16 percent of the land area of the state, albeit at very low densities. Of all federally listed species in California, the San Joaquin kit fox has by far the greatest overlap with agricultural areas, accounting for about 10 million acres in 14 counties, mostly in the agriculturally rich southern San Joaquin Valley. Other species that are interspersed with agricultural areas include birds, mammals, reptiles, amphibians, crustaceans and many plants.

    Pesticide Use Reporting

    Lead California Department of Pesticide Regulation [DPR]
    Description California's pesticide use reporting program is recognized as the most comprehensive in the world. In 1990, California became the first state to require full reporting of agricultural pesticide use in response to demands for more realistic and comprehensive pesticide use data. Under the program, all agricultural pesticide use must be reported monthly to county agricultural commissioners, who in turn, report the data to DPR. California has a broad legal definition of "agricultural use" so the reporting requirements include pesticide applications to parks, golf courses, cemeteries, rangeland, pastures, and along roadside and railroad rights-of-way. In addition, all postharvest pesticide treatments of agricultural commodities must be reported along with all pesticide treatments in poultry and fish production as well as some livestock applications. The primary exceptions to the reporting requirements are home-and-garden use and most industrial and institutional uses.

    Surface Water Protection Program

    Lead California Department of Pesticide Regulation [DPR]
    Description CA Department of Pesticide Regulation is the lead agency for regulating the registration, sales and use of pesticides in California. It is required by law to protect the environment, including surface waters, from environmentally harmful pesticides by prohibiting, regulating, or controlling the uses of such pesticides. The Surface Water Protection Program addresses both agricultural and nonagricultural sources of pesticide residues in surface waters. It has preventive and response components that reduce the presence of pesticides in surface waters. The preventive component includes local outreach to promote management practices that reduce pesticide runoff. Prevention also relies on DPR's registration process in which potential adverse effects to surface water quality, particularly those in high-risk situations are evaluated. The response component includes mitigation options to meet water quality goals, recognizing the value of self-regulating efforts to reduce pesticides in surface water as well as regulatory authorities of DPR, the State Water Resources Control Board (SWRCB) and the Regional Water Quality Control Boards (RWQCB).
