Aquatic Invasive Species (AIS)

Aquatic Invasive Species…

  • Are non-native plants, animals, and pathogens
  • Live primarily in water
  • Thrive in a new environment
  • Cause economic loss, environmental damage, and harm to human health

Thanks to the statewide cooperation of citizens, recreationalists, tourism industries, businesses, and agencies, less than 1% of Minnesota's waters are infested with AIS like zebra mussels and Eurasian watermilfoil. With 15,000 lakes, thousands of miles of rivers and streams, and acres of wetlands to protect, Minnesotans recognize the importance of acting to prevent and slow the spread of the state's current and potential AIS.

Public awareness and actions are essential to preventing the spread of AIS spread. Through research and public education, Minnesota Sea Grant is working to curtail the spread of AIS and manage existing invaders more effectively.

100 non-native species are reportedly living in Lake Superior and its wetlands.

Featured Initiatives

Clean-Drain-Dry-Dispose CD3Clean-Drain-Dry-Dispose CD3
Minnesota Sea Grant Aquatic Invasive Species Program Coordinator Doug Jensen served as a 2017 technical advisor for the Clean-Drain-Dry-Dispose CD3 boat-cleaning station program. The CD3 stations make it easy for boaters to clean their boats, motors and trailers after a day on the water and thereby reduce the spread of aquatic invasive species. Minnesota Sea Grant supports CD3 and other educational efforts aimed at encouraging boaters to help Stop Aquatic Hitchhikers!TM
Stop Aquatic Hitchhikers!
By following simple procedures each time we leave the water, we can stop aquatic hitchhikers. Check out the Stop Aquatic Hitchhikers' PSA produced by Brian Gordon, Northwestern College and the catalog of campaign materials produced by Wildlife Forever.
