California Fish And Game Code Section 1507

(a) (1) It is the intent of the Legislature to control mosquito production on managed wetland habitat that is owned or managed by the department, in a manner that does all of the following: (A) Maintains or enhances the waterfowl and other wildlife values of that habitat. (B) Minimizes financial costs to the department and local mosquito abatement districts. (C) Reduces the need for chemical treatment or other nonecological control of mosquitos. (D) Increases coordination and communication between the department, local mosquito abatement districts, and the State Department of Health Services. (E) Maintains and protects humans, domestic animals, and wildlife from vector-borne diseases such as West Nile virus. (2) The Legislature further finds and declares that the implementation of mosquito prevention best management practices on managed wetland habitat is critical to the department`s effort to reduce mosquito production on its wildlife management areas. (b) For the purposes of this section, the following definitions apply: (1) Managed wetland habitat means artificially irrigated and intensively managed wetland habitat administered primarily for the benefit of waterfowl and other wetland-dependent species. (2) Best management practices means management strategies jointly developed by the department, the State Department of Health Services, and mosquito abatement districts, in consultation with the Central Valley Habitat Joint Venture, for the ecological control of mosquitoes on managed wetland habitat. (3) Wildlife management area has the same meaning as set forth in subdivision (d) of Section 1504. (4) Mosquito abatement district has the same meaning as set forth in subdivision (f) of Section 2002 of the Health and Safety Code. (c) (1) A mosquito abatement district whose district boundaries include one or more wildlife management areas shall periodically, or at least semiannually, notify the department of those areas that exceed locally established mosquito population thresholds and associated mosquito control costs. The district shall provide the basis for the established thresholds to the department. Those thresholds and costs may be reviewed by the State Department of Health Services for conformity to generally acceptable mosquito control standards. (2) In order to reduce mosquito production at those wildlife management areas described in paragraph (1), the department shall do all of the following: (A) Identify best management practices for each applicable wildlife management area that, when implemented, would result in the mosquito population being reduced below the locally established threshold value while maintaining and enhancing the waterfowl and other wildlife values of that habitat. (B) In consultation with the local mosquito abatement district, develop and implement a mosquito control plan that applies the best management practices and any other necessary management practices at each applicable wildlife management area. (C) If capital improvements or other infrastructure are required to implement selected best management practices at a wildlife management area, the department shall work to secure any necessary funding through the board or other appropriate sources. (D) In coordination with the local mosquito abatement district, develop each spring an annual work plan for each wildlife management area that specifies the intended management activities for each unit of the wildlife management area and that, to the extent practicable, employs best management practices. (E) Implement the best management practices referenced in the annual work plan to the greatest extent possible, recognizing that unanticipated modifications to those plans are often necessary due to the uncertainty of water availability, water conveyance problems associated with beaver, muskrat and other animal activity, ditch, levee or pump failures, equipment breakdowns, rainfall or runoff-induced natural flooding, and other factors beyond the control of the department`s wetland managers, all of which may require periodic alteration of wetland management plans. (F) Meet with the local mosquito abatement district each summer to coordinate fall flooding of managed wetland habitat at each applicable wildlife management area and, if chemical treatment or other nonecological control is necessary, conduct post-fall flooding meetings to discuss the refinement of best management practices. (G) If the wetland occupies land outside the jurisdictional boundaries of a mosquito abatement district, the department may consult with the State Department of Health Services to determine which best management practices can be implemented in the absence of an organized local mosquito control program. (d) A mosquito abatement district whose boundaries include a wildlife management area described in paragraph (1) of subdivision (c) shall do all of the following: (1) In consultation with the department, develop standardized monitoring procedures for mosquito surveillance for each managed wetland habitat at each wildlife management area, and, when the monitoring procedures are completed, provide a copy of the procedures to the department. These procedures may be reviewed by the State Department of Health Services for conformity to generally accepted mosquito control standards. (2) Conduct posttreatment monitoring of wildlife management area lands and develop performance criteria to document mosquito control effectiveness. (3) Provide an annual report to the department specifying the types and quantities of pesticides used, types of habitat sprayed, and the total number of acres treated in a wildlife management area. The annual report shall also include recommendations for the refinement of best management practices to reduce the need for any chemical treatment or other nonecological control. (e) This section shall remain in effect only until January 1, 2010, and as of that date is repealed, unless a later enacted statute, that is enacted before January 1, 2010, deletes or extends that date.
