Cambarus fasciatus has been given a status of Data Deficient. This single basin endemic has a large range, with an EOO of over 4,600 km2, but which is in close proximity to a rapidly growing urban center. However, trend information is not known, the impacts of metropolitan growth have not been observed, and recent surveys have not been conducted.

Geographic Range [top]

Range Description:This species is restricted to Etowah River drainage in northwest Georgia, USA (Hobbs 1981), corresponding to a 6 county area. Most populations are located near the rapidly expanding Atlanta metropolitan area (R. Thoma, T. Jones, J. Cordeiro, pers. comm. 2009). The Extent of Occurrence of this species has been estimated as exceeding 4,600 km2.

Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is found in fast flowing streams with sandy bottoms littered with rocks. Adults have been found sheltering under rocks, while young have been found in leaf litter (Hobbs 1981).

Threats [top]

Major Threat(s): This species is located close to the Atlanta metropolitan area and is thus exposed to associated distubance (R. Thoma, T. Jones, J. Cordeiro, pers. comm. 2009). In addition the range of this species has been fragmented by a reservoir (Allatoona Lake) (R. Thoma, T. Jones, J. Cordeiro, pers. comm. 2009). Mining, agriculture and other human activities have caused the degradation of water quality in the Etowah  River basin in recent years (Walters et al. 2003). However, it is unknown if this is impacting upon this species, which maintains its entire global population within one river basin.

Conservation Actions [top]

Conservation Actions: This species has been given the heritage rank of G3 by NatureServe (Taylor et al. 2007, NatureServe 2009) and Threatened by the American Fisheries Society (Taylor et al. 2007). Further research on this species is required to clarify its abundance, range and threats.
