The Cumberlands and Southern Ridge & Valley Ecoregion (CSRV) is one of the most biologically diverse and critically imperiled areas in the United States. Encompassing roughly 37 million acres, the ecoregion stretches over 500 miles through portions of 6 states (Alabama, Georgia, Kentucky, Tennessee, Virginia, & West Virginia). Due to its broad climactic range, varied topography, and unique geologic history, the CSRV is a global center for both freshwater aquatic species and subterranean biodiversity, and also contains some of the largest hardwood forest expanses remaining in the eastern U.S. Given increasing pressures on critical habitats, tremendous need exists for a comprehensive approach to conserve the ecoregion’s most important biodiversity elements. As such, this plan details information about conservation measures necessary for sustaining the long-term biological integrity of the CSRV.
