Overview
The Cheat Mountain Salamander (Plethodon nettingi) is a rare and ecologically vital lungless salamander endemic strictly to the high-elevation red spruce forests of the Allegheny Mountains in West Virginia. First identified scientifically in 1938 and named in honor of prominent herpetologist M. Graham Netting, this relict Appalachian native represents a survivor of the Pleistocene ice age. Confined to isolated mountaintop ‘sky islands’ cloaked in ancient moss and liverworts, it functions as a primary bio-indicator for the health and recovery of the central Appalachian spruce ecosystem.
Biology and Physical Characteristics
Like all members of the family Plethodontidae, Plethodon nettingi is completely lungless, absorbing 100 percent of its oxygen through its moist, glandular skin and the vascular lining of its mouth cavity. It displays a dark chocolate-brown to jet-black dorsum flecked with fine, brassy gold or silvery flecks, fading to an unpatterned slate-gray belly. It possesses 17 to 19 distinct costal grooves along its flanks that help channel surface moisture across its body. Its head is small with large, prominent black eyes that provide keen nocturnal vision among leaf litter.
Behavior and Ecology
Cheat Mountain salamanders are strictly terrestrial, nocturnal wanderers that spend daylight hours concealed beneath rotting spruce logs, within moist rock crevices, or inside thick mats of Bazzania liverwort. Because they require constant high humidity for cutaneous respiration, they emerge to forage only on cool, damp nights when relative humidity approaches 100 percent. Reproduction is entirely terrestrial without an aquatic larval stage: females lay clutches of 4 to 12 eggs suspended like tiny grape clusters beneath rotting subterranean logs, guarding the clutch throughout summer until fully formed miniature salamanders hatch directly from the eggs.
Conservation and Human Impact
Plethodon nettingi is classified as Vulnerable on the IUCN Red List and federally listed as Threatened under the US Endangered Species Act. During the late 19th and early 20th centuries, widespread clearcut logging and subsequent devastating wildfires destroyed over 95 percent of West Virginia’s original virgin red spruce forests, restricting the species to fragmented mountaintop islands. Today, protected habitats within the Monongahela National Forest, combined with extensive spruce restoration initiatives by the US Forest Service and The Nature Conservancy, are successfully expanding continuous forest canopies to secure its long-term future.
Interesting Factoid
The Cheat Mountain Salamander has no lungs whatsoever; it breathes entirely through its skin, meaning it can only survive on misty mountaintops where the moss is always damp!
