Saturday, June 6 – Sunday, June 14, 2020
The goals of the California Invasive Species Action Week (CISAW) are to increase public awareness of invasive species issues and promote public participation in the fight against California's invasive species and their impacts on our natural resources.
Prevention is the most effective strategy in managing invasive species. However, hundreds of invasive plants and animals have already established in California and are rapidly spreading each year. These invaders are negatively impacting our waters, our native plants and animals (some of them rare, threatened, or endangered), our agriculture, our health, our economy, and our favorite recreational places. Help us celebrate California's Invasive Species Action Week, and more importantly, help stop the spread of invasive species, by volunteering to take action.
Are you planning to host an invasive species event during Action Week? Submit your event information (PDF Form) so we can add you to the Schedule of Events!
Can your facility or organization display or distribute Action Week brochures or art contest flyers (PDF) to help recruit event hosts, volunteers, or youth participants? Email Invasives@wildlife.ca.gov and tell us how many to send you! (Materials for 2020 will be available in early spring.)
Information for 2020 is coming soon. See the 2019 CISAW Brochure (PDF) and Poster (PDF) for more information!
