Abstract

A survey of the freshwater mussels of the Boone River conducted in September 1982 documented a fauna consisting of seventeen then extant or relict species. Analysis of museum records yielded one additional species unrecovered since 1937. Subsequent to the 1982 study, additional surveys were conducted in the region in 1984-1985 and 1998-1999 as a part of two statewide surveys. A comparison of the results of the three studies suggests a significant decline in the unionid fauna in the Boone River since 1982. While it is almost certain that a real decline in the fauna has occurred, the extent of this decline is subject to question due to differences in sampling methods.
