Threats [top]

Major Threat(s): The major threat to the species is clear-cut logging of its forest habitat, and transformation of the forest to agricultural land. Chytridiomycosis might also be a threat, since this is a high-elevation stream-dwelling species, and declines due to the disease have already been detected in other species of this genus.

Conservation Actions [top]

Conservation Actions: The range of this species does not include any protected areas, and protection of the forested areas surrounding San Cristobal de las Casas is needed. This species is listed as "Threatened" (Amenazada) by the Mexican government. In view of the threat of chytridiomycosis, the population status of this species should be closely monitored, and ex-situ populations might need to be established.
