Fourche Mountain Salamander (Plethodon fourchensis)
Description: The Fourche Mountain salamander has a sturdier body shape than most of the other salamander species in the locality. Its back is black with two rows of irregular grey blotches and a speckling of smaller pale spots. The underside is dark with a few lighter spots and the chin is pale.
Habitat: It is found in deciduous woodland high in the mountains especially in ravines and on north-facing slopes. It sometimes hybridizes with the Rich Mountain salamander (P. ouachitae) where their ranges overlap on the western side of Fourche Mountain.
Range: The Fourche Mountain salamander only occurs in the Fourche Mountains, the Shut-In Mountains, and the eastern side of Iron Fork Mountain in the Ouachita Mountain range in Arkansas and eastern Oklahoma.
Found in these States:
AR
Diet: It mainly feeds at night on small invertebrates such as insects, spiders, and worms.
Reproduction: Between May and September when the weather is hot and dry, it may aestivate underground, emerging to forage during any wet periods that may occur. It probably hibernates between November and March. Little is known of its breeding habits, but they are likely to be similar to the Rich Mountain salamander. The eggs are laid in underground chambers and brooded by the female, no aqueous larval stage exists and direct development takes place into juvenile salamanders. Females may breed in the fall or winter in alternate years.
Status: Listed as Near Threatened given that, while the species' appears to not currently be under significant threat, it is vulnerable to declines, has an extent of occurrence (EOO) of 275 km2 and occurs in a single threat-defined location in Ouachita National Forest, thus making it close to qualifying for a threatened listing under criterion B1.
Taxonomy: Once considered part of P. ouachitae, Plethodon fourchensis was described in 1979 based on genetic differences and geographical distinction.
