Freshwater Mussels are important

North America once had 300 species of native mussels. It was the most diverse mussel fauna on earth. Unfortunately, 38 of these species are presumed to be extinct, and another 77 species are considered critically impaired. These fascinating creatures are the most gravely imperiled group of animals in the country. What are the implications of the mussel's decline on our nation's rivers and streams? How can we help?
