Justification:
Cambarus batchi has been given a status of Least Concern. Despite a reasonably restricted range, it is a common species and secure where it occurs. It should however be noted, that this species is vulnerable to a one time stochastic event.

History:

1996	–	Vulnerable
1994	–	Indeterminate (Groombridge 1994)
1990	–	Indeterminate (IUCN 1990)
1988	–	Indeterminate (IUCN Conservation Monitoring Centre 1988)

Population [top]

Population:	There is no population information available for this species, although Burch (1990) found the species to occur in dense numbers in a three-county area.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	This species is a primary burrower; and spends almost its entire life in burrows near permanent ponds in areas of poor drainage. It constructs complex burrows ranging from 0.3 - 1.5 m in depth, while the surrounding vegetation is usually dense and covers the burrow entrances (Schuster 1976, Taylor et al. 2007). Burrows are found in ditch areas where water collects and the water table is approximately 1.5 m below the surface (Schuster 1976). Furthermore this species inhabits areas disturbed by human activities such as farming and mowing (R. Thoma, T. Jones, J. Cordeiro, pers. comm. 2009).
Systems:	Freshwater
