This species can be found in the Caddo Mountains, Ouachita Mountains region, south-western Arkansas, USA (Conant and Collins 1991; Petranka 1998), from 275-655m asl.
Habitat and Ecology
It is recorded as being "locally abundant in or near talus slopes or other rocky sites, particularly on north-facing slopes that support mature, mesic forests" (Petranka 1998). It moves into underground retreats under shaded talus or in abandoned mine shafts during hot, dry weather (Petranka 1998), during which large numbers have been found in abandoned mines on rock walls near water in summer (Saugey, Height and Heath 1985). It has also been found in secondary growth, mixed deciduous woods with some pine (Pope 1964). Eggs clusters have been found in mine shafts (Heath, Saugey and Heidt 1986).
It is locally common (Saugey, Height and Heath 1985; Petranka 1998). As of 2004, the Arkansas Natural Heritage Commission had recorded about 20 occurrences. Several of these were regarded as having good to excellent viability at the time of last visitation, but most of the occurrences did not have recent information.
Habitat loss and degradation represents a localized threat, and timber management activities and conversion of land to pine plantations probably also reduced suitable habitat for this species in the past (Warriner 2002).
Most populations are in the Ouachita National Forest, which affords this species some level of protection (Warriner 2002), and it is also state-listed as being a species of special concern.
Red List Status
Near Threatened (NT)
Listed as Near Threatened, because although the species is abundant within its small range, and might not be declining, its extent of occurrence is less than 5,000 km2, thus making the species close to qualifying for Vulnerable.
