Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Critically Endangered because of a drastic population decline, estimated to be more than 80% over the last three generations, inferred from the apparent disappearance of most of the population, probably due to chytridiomycosis.

Threats [top]

Major Threat(s): The most critical threat to this species is probably chytridiomycosis. Agriculture, both crops and livestock, as well as logging and infrastructure development for human settlement, are major threats to the species’ habitat.

Conservation Actions [top]

Conservation Actions: The range of this species includes the Reserva Ecológica Cotacachi-Cayapas. Surveys are needed to establish whether or not this species still survives in the wild. Given the threat of chytridiomycosis, successful conservation measures will probably need to include the maintenance of any surviving individuals in captivity.
