Shenandoah Mountain Salamander
Plethodon virginia · also called Shenandoah Mountain salamanders
High on a rocky Virginia ridgetop, far from the more favourable valley slopes a competing relative claimed long ago, a Shenandoah Mountain salamander makes do with drier, harder ground, one of only a handful of isolated peaks anywhere this species can still be found.
Overview
The Shenandoah Mountain salamander, Plethodon virginia, is a lungless salamander confined to a small number of isolated high-elevation peaks in western Virginia and adjacent West Virginia. Its extraordinarily narrow range, among the smallest of any North American salamander, and apparent displacement onto marginal ridgetop habitat make it one of the more precariously positioned amphibians in the Appalachians.
Squeezed onto the mountain’s leftovers
Rather than competing directly with a more common relative for the best available habitat, the Shenandoah Mountain salamander appears to have settled for what was left over, a drier, rockier ridgetop existence that has kept the species confined to just a handful of peaks.
Status
Vulnerable — confined to an extremely small total range across isolated Virginia and West Virginia peaks, with ongoing pressure from habitat disturbance and a drying climate.
Shenandoah Mountain Salamander: common questions
Why is the Shenandoah Mountain salamander confined to ridgetops?
A Shenandoah Mountain salamander is largely restricted to drier, rockier ridgetop habitat, a pattern likely caused by competitive exclusion from more favourable lower mountain slopes by the more widespread and abundant red-backed salamander, effectively pushing this rarer species onto less hospitable high ground.
How rare is the Shenandoah Mountain salamander?
The Shenandoah Mountain salamander occupies one of the smallest total geographic ranges of any salamander species in North America, restricted to a small number of isolated high-elevation peaks in the Shenandoah Mountain area of western Virginia and adjacent West Virginia, a rarity reflected in its Vulnerable conservation status.
What does the Shenandoah Mountain salamander look like?
The Shenandoah Mountain salamander typically displays a dark brown to black body with sparse, variable yellow or brassy flecking, a subtler and less boldly patterned appearance than several of its more common relatives within the same genus.
Where does the Shenandoah Mountain salamander live?
The Shenandoah Mountain salamander is native to high-elevation, often rocky forest habitat confined to a small number of isolated peaks in western Virginia and adjacent West Virginia, generally restricted to ridgetop terrain rather than the valleys below.
