This species is known only from the type locality in the Páramo de Palacio, Cundinamarca, Colombia, at an altitude of 3,000-3,300m asl.
Habitat and Ecology
It lives in páramo and does not tolerate habitat destruction. Breeding and larval development take place in fast-flowing streams.
This species was once abundant, but it has not been seen since 1993, despite repeated visits to the site.
Although not proven, the most likely cause of the decline of this species is chytridiomycosis, which has had a devastating impact on other high-altitude species of Atelopus. It is also likely to be threatened by fires set by cattle ranchers. In addition, introduced trout prey upon tadpoles in streams.
Occurs in Parque Nacional Natural Chingaza. Survey work is needed to determine the population status of this species; given the threat of chytridiomycosis, successful conservation measures will probably need to include the maintenance of any surviving individuals in captivity. There is also a need to control populations of trout within the National Park.
