This species is known only from the type locality: Alto de Caicedo, in Antioquia Department, Colombia, between 1,800 and 2,670m asl.
Habitat and Ecology
It occurs along forested streams in sub-Andean and Andean forests. It is restricted to forest habitats requiring canopy cover over the stream to maintain suitable conditions. Breeding and larval development take place in streams.
The current population status of this species is unknown, but it was not uncommon when last collected. There has not been any recent survey work for this species.
The most serious risk to this species is chytridiomycosis, which has had a devastating impact on other high-altitude species of Atelopus. Forests within the range of the species are being cleared for the planting of fruit trees, as well as illegal crops.
The known range of the species is close to Parque Nacional Natural Orquideas. Further survey work is needed to determine the population status of this species, and to establish whether or not it occurs outside the vicinity of the type locality. In view of the threat of chytridiomycosis, ex-situ populations might need to be established.
Red List Status
Critically Endangered (CR)
Specimens discussed by Cochran and Goin (1970) were subsequently named as Atelopus echeverrii.
