This website provides access to the list of freshwater gastropods (snails) in Canada and the United States as determined by the 2013 American Fisheries Society (AFS) Endangered Species Committee (ESC) on freshwater gastropods.
The snail part of this website provides access to the list of freshwater gastropods (snails) in Canada and the United States as determined by the 2013 American Fisheries Society (AFS) Endangered Species Committee (ESC) on freshwater gastropods. About 64% of snail species in freshwater habitats are in some level of imperilment and another 10% are considered extinct. At this website, one can view lists of native freshwater snails by state or province boundary, and plot distributions of snails by political boundaries. Lists can be downloaded for use in reports or analyses. While the committee did their best to define where snails occur or occurred in the past, much work still remains. We hope this website assists anyone interested in freshwater gastropods. There are links to the Fisheries publication, literature used to compile the list, online resources, snail recovery example stories, and other information.
