If you work or play in Washington’s many waterways, you may be unknowingly spreading aquatic invasive species (AIS) destructive to the state’s environment and economy. But you can also be a part of the solution, helping to stop or slow the spread of these damaging species.
We encourage the public to report possible invasive species. You can report non-native, invasive species through the Washington Invasive Species Council or the WA Invasives app (available in the Apple and Google app stores). Please call WDFW's Aquatic Invasive Species hotline with any questions at 1-888-WDFW-AIS or email ais@dfw.wa.gov.
Or review our printable brochure (PDF) to learn more about Aquatic Invasive Species in Washington state.
