A Guide to their Identification, Biology, and Conservation

The Center for Biodiversity and Conservation (CBC) has developed this web handbook as a "short-course" to the freshwater mussels occurring within 75 miles of New York City and throughout New Jersey. It is designed for naturalists, biologists, and resource managers working to conserve local freshwater ecosystems. The handbook includes a section on mussel morphology, a photo illustrated guide to 17 species, a key, habitat guide, glossary, bibliography of print and web resources, and essays on freshwater mussel taxonomy, biology, ecology, threats, conservation, and study methods, including a guide to local regulations. Information on this site is based on current knowledge, and is provided in the hope of encouraging and enabling further work on our local fauna.


The handbook is a collaborative project, with contributions from various organizations and individuals. It is based on a workshop hosted at AMNH by the Metropolitan Biodiversity Program and taught by Jay Cordeiro from NatureServe, and David Strayer of the Institute for Ecosystem Studies, and is published by the Center for Biodiversity and Conservation at the American Museum of Natural History.
