Help Kick Off California Invasive Species Action Week by Volunteering

The fourth annual California Invasive Species Action Week will run from Saturday, June 3 through Sunday, June 11. Sponsored by the California Department of Fish and Wildlife (CDFW), Invasive Species Action Week is a statewide event that provides the public with opportunities to learn about and take action against non-native plants and animals that harm our environment and the native species that live here.

Federal and state agencies and numerous organizations across the state have teamed up to host more than 40 individual Action Week events this year. Examples of upcoming public volunteer opportunities include:

  • Sacramento County: CDFW’s Marine Invasive Species Program will be hosting interactive displays, screening of educational videos and a chance to see live and preserved invaders from June 5-9 at the Nimbus Hatchery Visitor Center. This family-friendly opportunity will have activities for all ages and picnic facilities are on site.
  • Mendocino County: Mussel Dogs (a consulting and inspection service) will host a public demonstration of their Quagga and zebra mussel detection dogs’ work on the banks of Lake Mendocino on Saturday, June 3, from 7 a.m. to 3 p.m.
  • Sonoma County: California State Parks and Stewards of the Coast and Redwoods will host an invasive plant removal volunteer day in the Armstrong Redwoods State Natural Preserve on Wednesday, June 7, from 9 a.m. to noon.
  • Los Angeles County: The Mountain Restoration Trust needs volunteers to help trap and remove invasive red swamp crayfish from the Malibu Creek Watershed on Saturday, June 10 from 9 to 11 a.m.

Many other counties will also have volunteer opportunities this week. To view the full schedule of events and map, please visit www.wildlife.ca.gov/CISAW.

Don’t forget – stopping the spread of invasive species does not have to wait for the Action Week! Citizens can also contribute to a healthy environment by taking small, everyday actions – like selecting native plants for landscaping, cleaning your outdoor and aquatic gear after use, being responsible pet and aquaria owners, and reporting invasive species findings.

Another opportunity to monitor for invasive species during and beyond the Action Week is through California Nerodia Watch, the CDFW’s citizen-science monitoring project for invasive (and restricted) Nerodia watersnakes. Currently, Nerodia watersnake populations are established in Roseville, Folsom and Harbor City, with several sightings reported in the Sacramento-San Joaquin Delta. Nerodia are notorious predators of fish and amphibians, and if their range expands, they will pose a serious threat to nearby endangered fish and wildlife. Members of the public are encouraged to help CDFW biologists to monitor and prevent the spread of existing populations! Visit the CDFW invasive species profiles at www.wildlife.ca.gov/conservation/invasives/species to learn more and report observations through the iNaturalist project webpage (www.inaturalist.org/projects/california-nerodia-watch) or by downloading the iNaturalist smartphone app.
