These recently proposed COAs, which include areas such as rivers, streams, wetlands, lakes, forest, migratory bird corridors, protected greenspaces, and other areas where targeted conservation planning and action can take place on public and private lands, are being used to identify conservation opportunities and priorities, as well as stakeholders that are already working in these places or could be valuable partners in this conservation effort. An example of a proposed COA includes the Buffalo River, which is home to one of the last remaining populations of the hellbender, the largest species of aquatic North American salamander, in the region. Another COA, the Western Highland Rim, has been determined to have a significant number of intact forests that provide habitat for forest breeding birds, like the Cerulean Warbler, but is an area where active logging is leading to fragmentation and water quality impacts. In the Mill Creek Watershed COA, the only place in the world where the federally endangered Nashville Crayfish can be found, residential and commercial development threaten this species' existence. Yet another important COA includes karst and cave habitat, like that found in East Tennessee that is providing habitat for animals such as the Eastern Small-footed Bat.
