Assessment Information [top]

Red List Category & Criteria:	Critically Endangered B1ab(iii) ver 3.1
Year Published:	2010
Assessor/s:	Crandall, K.A. & Cordeiro, J.
Reviewer/s:	Collen, B. & Richman, N.
Contributor/s:	Livingston, F., Livingston, F., Soulsby, A.-M., Batchelor, A., Dyer, E., Whitton, F., Milligan, H.T., Smith, J., Lutz, M.L., De Silva, R., McGuinness, S., Kasthala, G., Jopling, B., Sullivan, K. & Cryer, G.
Justification: Cambarus laconensis has been assessed as Critically Endangered B1ab(iii). This species is known from one location, and though it is suspected to occur in other locations, it has not been found despite extensive survey work. Furthermore, the type location has been degraded due to road construction, and its habitat is under a continuing decline from road pollution. Further research is required to determine the abundance of this species, whether it occurs in more locations, and to what extent it is impacted upon by threats.

Geographic Range [top]

Range Description:	This species is restricted to one locality in northern Alabama along the southern border of the Highland Rim in the southern Appalachians although may exist in one or two other caves nearby (Buhay and Crandall 2009).
Countries:	Native: United States (Alabama)

Population [top]

Population:	Five specimens were recorded from the type locality (Buhay et al. 2006). It is believed that there are more specimens in other caves although none have been found during extensive surveys (Buhay et al. 2006).
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	This is a cave dwelling species which inhabits subterranean hydrological systems such as small standing water pools and stream beds (Buhay and Crandall 2009).
Systems:	Freshwater

Threats [top]

Major Threat(s):	The type locality of this species was blasted open for road construction and is currently found underneath a highway (Buhay and Crandall 2009) so is subject to traffic pollution.
