Justification
Listed as Critically Endangered because of a projected population decline, estimated to be more than 80% over the next ten years, inferred from declines in other high altitude Atelopus species in the same region, probably due to chytridiomycosis.

Threats

Major Threats
The most serious risk to this species is chytridiomycosis, which has had a devastating impact on other high-altitude species of Atelopus. Other, localized threats include habitat loss caused by agricultural expansion (cattle ranching and the planting of illegal crops), water extraction, and fumigation of illegal crops. Climate change might also be impacting the species.

Management

Conservation Actions

Conservation Actions
It occurs in the Parque Nacional Natural Puracé. More research into the species' range, ecological requirements, and population status is needed, and in particular surveys are needed to determine whether or not the species is currently in decline as has been evidenced in other high-elevation stream-dwelling Atelopus species in the region. A captive-breeding programme might need to be established for this species.
