The rabbitsfoot, a freshwater mussel, is a threatened species. It is found in rivers and streams in Alabama, Arkansas, Georgia, Kansas, Kentucky, Illinois, Indiana, Louisiana, Mississippi, Missouri, Ohio, Oklahoma, Pennsylvania, Tennessee, and West Virginia. We estimate that it has been lost from about 64 percent of its historical range. While 51 of 140 historical populations are still present, only 11 populations are viable; 23 populations are at risk of extirpation and 17 populations do not seem to be reproducing at a level that can sustain the populations. Most of the existing rabbitsfoot populations are marginal to small and isolated.
