Species Level Risk Assessments Explorer

If you are looking for Risk Assessment METHODS, go to the Assessment Methods Explorer

This explorer is produced in collaboration with the Great Lakes Panel on Aquatic Nuisance Species' Risk Assessment Ad Hoc Committee.

You may search the risk assessments and species regulations by either specifying the full species name directly from the first drop-down menu, or perform a taxonomic search. Both state and federal level regulations are displayed in the map, with the latter portrayed in the inset graphics of the United States and Canada. For more detailed information on the species regulations described in the map and to view tribal regulations, please select the table view. To learn more about the methods behind each species' risk assessment, click the method title for an entry.
