From the IUCN Red List Species Account:

 

Range Description

This species is known only from the west slope of the Cofre de Perote Mountain, central Veracruz, Mexico, at 2,500-2,550 m asl.

Habitat and Ecology

It inhabits dry pine forest, and is found only in mountain streams in crevices and rocks.

Population

This species used to be abundant, but it has not been collected in over 10 years despite numerous surveys in suitable habitats in the area from which it has been recorded.

Population Trend

decreasing

Major Threats

The major threat to this species is the disappearance of suitable stream habitat. Its apparent disappearance in areas of remaining suitable habitat is suggestive of a threat such as chytridiomycosis, so this requires investigation. At the type locality, the frogs were known only from a single ravine and spring source. The spring had been capped and the flow directed via pipeline down the mountain towards an army outpost below. It appears there is no habitat for this species to breed in since the diversion of the spring flow (T. Burkhardt pers. comm. 2006).

Conservation Actions

The range of this species falls entirely in the Parque Nacional Cofre de Perote. In view of the risk of chytridiomycosis, it is a very high priority to conduct surveys to determine whether or not this species still survives; surviving individuals might need to form the basis for the establishment of an ex-situ population.

Red List Status

Critically Endangered (CR)

Rationale

Listed as Critically Endangered because its Extent of Occurrence is less than 100 km2 and its Area Of Occupancy is less than 10km2, all individuals are in a single location, and there is continuing decline in the extent and quality of its habitat in Veracruz, Mexico, and the number of mature individuals probably due to the impacts of chytridiomycosis.

Taxonomic Notes

This species was previously included in the genus Hyla but has recently been moved to the genus Plectrohyla (Faivovich et al. 2005).
