About Plethodon ouachitae Dunn & Heinze, 1933
Rich Mountain salamanders (Plethodon ouachitae Dunn & Heinze, 1933) reach a snout-to-vent length of approximately 5 centimetres (2.0 in). Their base color is slatey-grey with a mottled pattern, which helps them remain inconspicuous against their surroundings. Glands on their backs secrete a noxious substance that acts to deter predators. Distinct lineages of this species have characteristic color variations that align with the specific mountain range where they are found. The Rich Mountain salamander was first collected at Rich Mountain, located east of Page, Oklahoma in the Ouachita Mountains. This species is only found on six separate mountains: Buffalo, Winding Stair, Black Fork, Kiamichi, Round, and Rich Mountain. It is classified as a sky island species because its entire range is restricted to strict high elevation areas. Where the range of Rich Mountain salamanders overlaps with that of the Fourche Mountain salamander (Plethodon fourchensis), some hybridization occurs. Their preferred habitat is mixed deciduous woodland, especially on north-facing slopes near wet seeps. They can also be found in the regionally common talus rock glaciers of the Ouachitas, under logs, rocks and debris, and at cave entrances.
