Number of Occurrences> 300
Rank Reasons
This species is moderately widespread and abundant. This species, although extent of occurrence is probably less than 20,000 km2, has a presumed large population, and because it is not in decline or is unlikely to be declining fast enough to qualify for listing in a more threatened category.
Range Extent Comments
According to Burch (1989), citing Goodrich (1941), ranges (as Elimia gerhardti) from Coosa River basin, from north Georgia to lower tributaries of the Coosa River in Alabama. According to Gordon (pers. comm.) it also occurs in Tennessee River near Chattanooga.
Occurrences Comments
It is widespread in the Coosa River system and tributaries (Mirarchi, 2004; as Elimia gerhardti), including the northwest corner of Georgia into creeks in Alabama on the southern and eastern side of the Coosa River (Goodrich, 1934). It is widely distributed in tributaries and small streams within the Coosa River system of Alabama and Georgia but the type locality of "Chattahoochee River, Columbus, Georgia" is likely incorrect (Thompson, 2000). It also occurs in the Etowah River system in Georgia (Burkhead et al., 1997).
