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).

Threats [top]

Major Threat(s):

It is unknown if there are any major threats impacting this species. However, as this species is only known from one location it may be at risk from stochastic disturbance. This species inhabits areas disturbed by human activities such as farming and mowing (R. Thoma, T. Jones, J. Cordeiro, pers. comm. 2009).

Conservation Actions [top]

Conservation Actions: This species has been given the heritage rank of G3 by NatureServe (Taylor et al. 2007, NatureServe 2009) and is considered vulnerable by the American Fisheries Society (Taylor et al. 2007). This species is currently contained within a Wildlife Management Area (i.e. Central Kentucky Wildlife Management Area) (R. Thoma, T. Jones, J. Cordeiro, pers. comm. 2009).
