Research Project: Areawide Management of Aquatic Weeds in Contra Costa County

Location: Invasive Species and Pollinator Health

Project Number: 2030-22000-029-04-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 16, 2014
End Date: Sep 15, 2019

The parties agree that meeting the objectives of this project will strengthen and enhance on-going research and control efforts within the scope of this agreement. This research will help fill knowledge gaps on the importance of aquatic weeds in the Western US and specifically in the Sacramento/San Joaquin River Delta. This work will further support efforts in helping to control aquatic weeds and mosquitoes. It will also help address biological control of invasive plants in the wider ecosystem and should lead toward future sustainable management options for waterway and resource managers.

Existing County staff will work with USDA, Agricultural Research Service (USDA) and University of California, Davis (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.
