The southeast United States’ rivers and streams support the most diverse unionid (freshwater mussel) fauna on earth. These species are a focus of the GCP LCC because their sensitivity to habitat degradation, fish community changes, and changes in water quality and quantity make them akin to the proverbial ‘canary in the coal mine.’ They are essential components of riverine ecosystems, influencing nutrient cycling and macro-invertebrate diversity. Their decline during the past century stems from overharvest, water pollution, habitat fragmentation, and introduction of nonindigenous predators and exotic mollusks; however, habitat degradation has been the most influential.

Rivers and streams of the southeastern United States support the most diverse unionid (freshwater) mussel fauna on earth. Unionids are essential components of riverine ecosystems, often dominating benthic biomass and influencing nutrient cycling and macro-invertebrate diversity. Unionids are one of the most endangered groups of freshwater organisms in the United States. The decline of native freshwater mussels during the past century has resulted from a variety of factors including overharvest, water pollution, land use alteration, and the introduction of invasive species. However, the most influential anthropogenic factor impacting unionids has been habitat degradation. Another factor that compounds efforts to...
