Tracking progress toward harmonization of species regulations: how it’s measured

The Great Lakes and St. Lawrence Governors and Premiers have identified a list of 21 “least wanted” aquatic invasive species 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, including via regulation. Blue Accounting tracks how many of these 21 species are regulated in each Great Lakes state and province.
