Description
INTRODUCTION Freshwater mussels (Bivalvia) are the most imperiled group of organisms in North America (Williams et al., 1993). Of the approximate 300 species native to North America, nearly two-thirds are extinct, federally-listed as endangered or threatened, or are in need of conservation. This reduction also is evident in Illinois. Of the 80 historical species known to inhabit the state, 19 are extirpated from Illinois, 16 are state-endangered, eight are state-threatened, and only 22 are considered to have relatively stable populations within Illinois (DeWalt et al., 2009). Factors responsible for the decline in freshwater mussels include habitat destruction, environmental contamination, and invasion of exotic species (Williams et al., 1993).
