Wisconsin Mussels
Over half of Wisconsin's 51 native mussel species (also known as clams) are listed as species of greatest
conservation need or we need information on where they currently occur. Threats like habitat alteration
(dams, siltation) and the presence of invasive mussels (zebra mussels) pose major threats to the existence
of our native mussels. The Mussel Monitoring Program of Wisconsin would like your help in finding out what
mussels occur in your area!
