The United States Fish & Wildlife Service, Alabama Department of Conservation and Natural Resources and Geological Survey of Alabama have selected watersheds and river corridors in the five major hydrologic unit (HU-4) subregions in Alabama and adjoining states to prioritize activities for the management, recovery, and restoration of populations of rare fishes, mussels, snails, and crayfishes. These Strategic Habitat Units (SHUs) and Strategic River Reach Units (SRRUs) contain a substantial part of the area's remaining high quality water courses and reflect the variety of aquatic habitats occupied by these species - historically and presently.

These units were selected based on:
Suitable habitat for these species includes:
The purpose of designating these SHUs and SRRUs is to facilitate the coordination of watershed management and restoration efforts that address habitat and water quality issues.
