Aquatic invasive species (AIS) are plants, animals and microscopic organisms that have caused serious problems in aquatic ecosystems outside of their native range. These species threaten the biodiversity and function of the Great Lakes ecosystem. Michigan Sea Grant supports research, outreach and education to prevent new introductions of AIS into the Great Lakes and control the spread of established AIS populations.
