Admin Measure Summary
The California Department of Fish and Wildlife (CDFW) and other appropriate agencies fully implement the 2014 Ecosystem Restoration Program "Conservation Strategy" list for Strategic Goal 5.
The CDFW 2014 Ecosystem Restoration Program Conservation Strategy contains conservation priorities for addressing nonnative invasive species (NIS) under the Strategic Goal 5. CDFW Invasive Species Program leads implementation activities to prevent, control, and educate about NIS. These priority actions are currently being implemented:
- The Nutria Eradication Program, established in 2019 and continuing in 2020, conducts surveillance and trapping of nutria in the San Joaquin Valley to prevent their continued spread into the Delta. Trapped nutria are removed from the Delta. Nutria Identification Flyer and Nutria Pocket Guide aid in field identification of nutria.
- CDFW Bay-Delta Region conducts ongoing fish surveys/monitoring in the Delta.
- The Quagga/Zebra Mussel Program works within the Delta and its watershed to prevent the introduction and spread of dreissenid mussels.
- CDFW (Lands Program) manages properties to prevent and control of non-indigenous species (NIS).
- Upon requests from the Division of Boating and Waterways, CDFW performs a risk assessment to determine if aquatic weeds are likely to be invasive and cause negative impacts within the Delta.
- CDFW Invasive Species Program is working to assess the impacts of mute swans in the Delta and its watershed.
- CDFW is working to eradicate non-native watersnakes before they spread into the Delta.
- CDFW developed a mobile application for public identification and reporting of NIS in 2020.
- CDFW engaged and educated the public with signages posted about New Zealand mudsnails and quagga/zebra mussels; staffed booths at public events to engage and educate boaters.
- The Surface Water Ambient Monitoring Program (SWAMP) monitors watersheds around the Delta, incidentally also for invasive species.

Prevent Introduction of and Manage Nonnative Species Impacts
Delta Plan Recommendation
ER R7. Prioritize and Implement Actions to Control Nonnative Invasive Species. The California Department of Fish and Wildlife and other appropriate agencies should prioritize and fully implement the list of “Stage 2 Actions for Nonnative Invasive Species” and accompanying text shown in Appendix J taken from the Conservation Strategy for Restoration of the Sacramento–San Joaquin Delta Ecological Management Zone and the Sacramento and San Joaquin Valley Regions (DFG 2011). Implementation of the Stage 2 actions should include the development of performance measures and monitoring plans to support adaptive management.
