"Least Wanted" Aquatic Invasive Species List (PDF | 1.46 MB)

Conference of Great Lakes and St. Lawrence Governors and Premiers.

The Great Lakes and St. Lawrence Governors and Premiers have identified the "least wanted" aquatic invasive species (AIS) that present an imminent threat to the Great Lakes-St. Lawrence River region. In 2013, the Governors and Premiers committed to take priority action on the transfer of these species to and within the region. Since then, the states and provinces have taken more than 50 separate actions to restrict these high-risk AIS, and the US federal government has similarly restricted four of the species.

The species watch list identifies species that are likely to have a high or moderate ecological and/or socioeconomic impact if they established in or spread to new locations in the Great Lakes Basin. The watch list was compiled using several regional risk assessment sources and was developed as part of the Aquatic Invasive Species Interstate Surveillance Framework for the U.S. Waters of the Great Lakes.
