If you plan to use your own boat or angler float tube, you’ll need a permit and a free Yellowstone aquatic invasive species inspection. You can speed up the inspection process by arriving with a boat that is clean, drained, and dry. Watercraft that arrive dirty or with standing water will be subject to decontamination. Watercraft that cannot be properly decontaminated will be prohibited from launching.

This interactive database contains information on the plants currently included in the Cal-IPC Invasive Plant Inventory. The Inventory categorizes plants as High, Moderate, or Limited, reflecting the level of each species' negative ecological impact in California. Includes options to search for species by region and by habitat type. The database provides a better view of information on each species and allows users to download the entire Inventory as a spreadsheet.

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.
