Research Project: Areawide Management of Aquatic Weeds in San Joaquin County

Location: Invasive Species and Pollinator Health

Project Number: 2030-22000-029-03-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 8, 2014
End Date: Jun 30, 2019

To monitor and assess aquatic weed/insect infestations in the Southern Sacramento/ San Joaquin River Delta area and to assist USDA, Agricultural Research Service and the California Division of Boating and Waterways in priority setting for weed management efforts in that area. To assess and manage mosquito populations in areas infested with aquatic weeds in cooperation with USDA-ARS and UC Davis. To assist USDA-ARS on the field rearing and release of new biological control agents for use against various aquatic weeds infesting the Delta.

Existing County staff will work with USDA and UC Davis scientists to characterize aquatic weed and mosquito densities in the Sacramento/ San Joaquin River Delta through on-going monitoring and control programs. Data will be shared between institutions and supplemental data will be collected by the combined group to better quantify the relationship between aquatic weeds and potential disease vectoring mosquitoes. Project resources will be used to supplement County staff where appropriate to fulfill these activities. Additionally, weed control advice will be provided from the County to USDA and Boating and Waterways to aid in vector control. County staff will also participate in USDA planned biological control activities through field rearing of important biological control agents and then work with USDA and local landowners/ marina managers to release and assess new natural enemies of target aquatic weeds.
