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.
