Desmognathus monticola

Two subspecies, monticola and jeffersoni, have been recognized by some authors. The latter has been thought to be confined to the Blue Ridge Mountains of Virginia, but Folkerts (1968) noted several indications of intermediacy between the two described forms in Alabama, thus casting doubt on the validity of these subspecific designations. Because of the evident taxonomic uncertainty, Mount (1975) chose not to assign Alabama populations to subspecies. Recent major accounts of the species and subspecies of North American amphibians and reptiles (e.g. Crother 2017) regarded D. monticola as having no valid subspecies.

Beamer and Lamb (2020), in their discussion of Desmognathus mtDNA phylogenetics, discussed phylogeographic structure. Pyron et al. (2023) described the southern D. monticola lineages A/C as a new species, D. cheaha.

This species is widespread and abundant in the eastern U.S. The population has not suffered any large, historical rangewide declines and appears relatively stable.

This species is endemic to the eastern United States. It is found from southwestern Pennsylvania southwest in uplands through West Virginia, western Maryland, western and northern Virginia, eastern Kentucky, western North Carolina, eastern Tennessee, western South Carolina, and northern Georgia to the vicinity of Chattahoochee National Forest (Conant and Collins 1991, Petranka 1998, Regester et al. 2020, Pyron et al. 2023). Evidently does not occur north or west of the Ohio River in the northern part of the range. Using Global Biodiversity Information Facility (GBIF) (2025) records from 2005-2025 from within the range prescribed by Pyron et al. (2023), range extent is estimated to be 229,276 km² (RARECAT 2025).

Formerly considered present in Alabama and northwest Florida; these populations are now considered a new species: D. cheaha (Pyron et al. 2023).

Represented by many and/or large occurrences throughout the range, based on available detailed distribution maps (e.g., Mount 1975, Green and Pauley 1987, Redmond and Scott 1996, Hulse et al. 2001, Regester et al. 2020, Pyron et al. 2023).

This species is primarily threatened by clearcutting of mature hardwood stands along riparian corridors, which can reduce abundance for several decades (Regester et al. 2020). It is not considered highly susceptible to climate change nor disease impacting other amphibian species in the range (Regester et al. 2020).
