About Allegheny Mountain dusky salamander

The Allegheny Mountain dusky salamander, scientifically known as Desmognathus ochrophaeus, is a species of lungless salamander native to eastern North America. It inhabits a range that extends across the eastern United States and into Canada, including specific populations in southern Ontario and Quebec.

Distribution and Habitat

This salamander thrives in a variety of natural environments, including temperate forests, along rivers and intermittent streams, near freshwater springs, and in rocky terrain. Its presence is noted in areas where the ground is consistently moist, such as under stones, logs, and bark.

Physical Description

As a medium-sized salamander, the Allegheny Mountain dusky salamander typically reaches an adult length of approximately 10 cm. Its coloration is highly variable but often presents as brownish with a distinct light stripe running down its back. This stripe is frequently accompanied by a central row of dark spots, with additional dark pigments along the flanks. A notable physical characteristic is that its hind legs are proportionally larger and sturdier than its front legs. Being a member of the Plethodontidae family, adults lack lungs and must maintain moist skin for respiration.

Conservation Status in Canada

Canadian populations of Desmognathus ochrophaeus are subject to significant conservation measures. The Carolinian population in Ontario was designated as endangered in 2009, and the Appalachian population in Quebec received the same designation in April 2021. Previously, from 1998 to 2007, these populations were classified as a COSEWIC 'Species of Special Concern.' Ontario's Endangered Species Act, 2007, provides legal protection against killing, harming, or possessing the species. Similarly, salamanders on Niagara Parks Commission property are protected under the Niagara Parks Act.
