Notice for Public Input on Refuge Mosquito Management

Draft Mosquito Surveillance and Control Compatibility Determination – San Joaquin River National Wildlife Refuge


November 29, 2017


The U. S. Fish and Wildlife Service (Service) is conducting a review of mosquito surveillance and control activities on San Joaquin River National Wildlife Refuge in Stanislaus and San Joaquin Counties, California.


In 2006, the Service completed a Comprehensive Conservation Plan (CCP), which guides the long range management of San Joaquin River National Wildlife Refuge.  During the planning process, mosquito surveillance and control were evaluated and found to be a compatible use on San Joaquin River National Wildlife Refuge.  A compatible use is a proposed or existing wildlife-dependent recreational use or any other use of a national wildlife refuge that, based on sound professional judgment, will not materially interfere with or detract from the fulfillment of the National Wildlife Refuge System mission or the purpose of the National Wildlife Refuge. A compatibility determination document is developed to facilitate evaluation of such uses.  Compatibility determinations for mosquito surveillance and control need to be re-evaluated every 10 years, in accordance with Service policy.


The Service has drafted a Revised Compatibility Determination for mosquito surveillance and control on San Joaquin River National Wildlife Refuge. The primary goal is to reduce the risk of a serious health threat to both humans and wildlife.   The Service proposes to continue collaboration with local vector control districts to implement an integrated approach utilizing biological, cultural, physical and chemical mosquito control methods.


The Draft Compatibility Determination will be available for public review from December 1 to December 30, 2017.
