This species occurs in Parque Nacional Natural Chingaza, Colombia, between 2,900 and 3,350m asl.
Habitat and Ecology
It occurs in Andean cloud forests and páramos. Breeding and larval development take place in streams.
This species was common up until 1996, but four expeditions in 1998 and 2003 failed to turn up a single individual at any of the previous known localities.
The major threat is likely to be chytridiomycosis, which has resulted in catastrophic declines of many other species of Atelopus. Cattle grazing is also a threat to the habitat of this species, and introduced trout have a negative impact on reproductive success.
This species occurs in the Parque Nacional Natural Chingaza. Further survey work is required to determine whether or not this species still persists in the wild. In view of the threat of chytridiomycosis, any surviving individuals might need to form the basis for the establishment of an ex-situ population.
