Pigeon Mountain Salamander vs Cow Knob Salamander
A Pigeon Mountain salamander and a Cow Knob salamander are both lungless Appalachian salamanders known from an extraordinarily narrow natural range, one confined to a single Georgia mountain and the other to a single ridge on the Virginia-West Virginia border.

| Elevation preference | Not specifically high-elevation | Specifically high-elevation |
| Described | 1993 | Earlier, longer-recognised species |
| Conservation status | Vulnerable | Near Threatened |

Pigeon Mountain Salamander vs Cow Knob Salamander: common questions
What makes the Pigeon Mountain salamander and Cow Knob salamander so range-restricted?
Each species depends on a specific set of consistently damp, cool conditions, limestone rock crevices for the Pigeon Mountain salamander and high-elevation forest for the Cow Knob salamander, that happen to occur reliably only within one particular landform, a single Georgia mountain in one case and a single Appalachian ridge in the other, leaving each species with essentially no equivalent habitat to expand into elsewhere.
How can you tell a Pigeon Mountain salamander from a Cow Knob salamander?
Beyond their completely non-overlapping ranges hundreds of miles apart, the Pigeon Mountain salamander is a notably accomplished climber often found on vertical limestone rock faces, while the Cow Knob salamander shows small yellow or brassy spots across a darker body and stays within cool, high-elevation forest habitat along its home ridge.
Why are both of these salamanders considered species of conservation concern?
Because each species' entire known population is confined to such a small area, any disturbance from quarrying, development, logging, or heavy recreational use, whether on Pigeon Mountain's cliffs or the Cow Knob salamander's ridge, has the potential to significantly affect the species as a whole, since neither has a substantial population elsewhere to fall back on.
