The Obed Wild and Scenic River, located on the Cumberland Plateau, is in a region where major declines and mass mortality of mussels have been observed. The Wild and Scenic River contains designated critical habitat for the federally endangered endemic Tennessee Bean ( Venustaconcha trabalis; aka Purple Bean). Water quality and habitat conditions in the Obed are critical factors for recovery of...
Conservation and Restoration of Native Freshwater Mussels
Freshwater mussels are the most imperiled group of animals in North America, with 66% of species at risk. Mussel populations are declining globally, but the factors contributing to these declines are largely unknown. Habitat fragmentation and alteration, point- and non-point source pollution, navigation-related impacts, and exotic species introductions are thought to be responsible for mussel...
