Aquatic invasive species are organisms that invade ecosystems beyond their natural, historic range. They can damage native ecosystems or commercial, agricultural, or recreational activities dependent on these ecosystems.

Educating About Invaders

Oregon Sea Grant works with many collaborators to teach audiences of all ages, including school-aged children, recreational boaters, and government entities about invasive species and the risks they pose. Learn more about some of our invasive species programs.
