This species occurs on the northern slopes of Sierra de Juárez, northern Oaxaca, Mexico, at 1,580-2,020m asl.
Habitat and Ecology
This stream-breeding species exclusively inhabits cloud forest in the highlands of the Sierra de Juárez, and is found in moist and rocky habitats with abundant aquatic vegetation along streams.
There is no information on the population status of this species; however, it is probably quite rare, and there have only been a few individuals collected since the 1970s.
The transformation and clearance of original cloud forest in the region is the main threat to this species. In southern Mexico, tadpoles have been found with damaged mouthparts, an indication of chytrid infection.
The protection of the Sierra de Juárez forest fragments is extremely urgent since there are currently no protected areas in this region. Further surveys to establish the species' population status are also required, and in view of the severe risk of chytridiomycosis, ex-situ populations might need to be established. This species is listed as "Threatened" (Amenazada) by the Mexican government.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because of a projected population decline, estimated to be more than 80% over the next ten years, due to continuing decline in the extent and quality of its habitat, and the impacts of chytridiomycosis.
This species was previously included in the genus Hyla but has recently been moved to the genus Plectrohyla (Faivovich et al. 2005).
