This species occurs at high elevations in the Sierra Madre Occidental of Mexico, from Durango and adjacent Sinaloa southward to Michoacán, Guerrero and Oaxaca, and to the east in the central Volcanic Belt to Hidalgo and Puebla.
Habitat and Ecology
It occurs only at high elevations in pine-oak and pine-fir forests and in the associated streams. It is a stream breeding amphibian.
It is a common species within appropriate habitat.
Disturbance, clearance and modification of the species' habitat is the main threat. Chytridiomycosis might be a future threat, as it is a high-elevation, stream dweller, and declines due to the disease have already been detected amongst other species of this genus elsewhere.
Protection and restoration of the degraded forest areas is recommended. The species' range includes a few protected areas, but these need restoration and better management at present. This species is protected by Mexican law under the "Special Protection" category (Pr).
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
This species was previously within the genus Hyla but has recently been moved to the genus Plectrohyla (Faivovich, et al., 2005). This form is a complex of more than one species that needs taxonomic revision.
