The distribution of Cumberlandian mollusks in the Tennessee Valley is one of nine research activities developed as part of TVA's Cumberlandian Mollusk Conservation Program (CMCP). The name Cumberlandian refers to an endemic faunal assemblage that encompasses portions of 7 states bordering the southern Appalachian Mountains and the Cumberland Plateau Region. This geographic region is known as one of the major centers for mussel speciation and is considered the most prolific areas of the world for this particular group of organisms. Nine Tennessee Valley streams were selected for intensive qualitative and quantitative mussel surveys under Activity I of the CMCP. The surveys were designed to gather information on the present distribution of Cumberlandian mollusks. The streams chosen for surveys were based on the documented presence of diverse mussel fauna, endangered mussels, and/or sufficient information (diverse fish fauna, good water quality, etc.) to suggest potential for occurrence of diverse mussel fauna or endangered species.
