California Invasive Species Action Week (June 6-14, 2020)

California Department of Fish and Wildlife.

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.
