Mussel Monitoring Program of Wisconsin


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!
