California boaters, anglers, and water users are invited to take part in a free virtual workshop focused on preventing the spread of aquatic invasive species (AIS) across the state’s waterways. Scheduled for May 14, 2026, the three-hour session will provide practical guidance on identifying and stopping both saltwater and freshwater invasive species before they impact uninfested areas.
Hosted by a coalition of agencies including California State Parks Division of Boating and Waterways, the California Coastal Commission, the California Department of Fish and Wildlife, the California State Lands Commission, and the U.S. Fish and Wildlife Service, the workshop aims to educate participants on the growing environmental and economic risks associated with AIS.
Attendees will gain a better understanding of how invasive species affect ecosystems, recreational opportunities, and local economies. The workshop will also cover the biology of several high-priority species and how to recognize them in the field. Freshwater threats include quagga, zebra, and golden mussels, while saltwater species of concern include Asian kelp (wakame), clubbed tunicate, devil weed, green crab, and the Asian date mussel.
In addition to identification, the session will outline current management and control strategies being used throughout California. Organizers will also emphasize actionable steps individuals can take to help limit the spread of invasive species, including proper inspection and cleaning of boats, trailers, and equipment after use.
The workshop is open to anyone who accesses California’s waterways, from recreational boaters to shoreline visitors. Advance registration is required to attend, and participants must sign up by May 12, 2026.
The virtual workshop will take place on Thursday, May 14, from 9:00 a.m. to 12:00 p.m.
