Range Description

This species is known from the northern slope of the Parque Nacional Natural Sierra Nevada de Santa Marta in the Department of Magdalena, and from the Guatapuri river basin in the department of Cesar, in northern Colombia, between 1,500 and 2,900m asl.

Habitat and Ecology

It occurs in sub-Andean and Andean forests. It can also adapt to some modification of its habitat. It lays egg chains in streams, where the tadpoles also develop.

Population

This species was considered to be common when it was last recorded in 1992. There have been no further surveys within its range since then.

Population Trend

Decreasing

Major Threats

The most serious risk to this species is chytridiomycosis, which has had a devastating impact on other high-altitude Atelopus species. Habitat fragmentation, primarily due to agriculture, and pollution, resulting from agricultural practices and the fumigation of crops, are also major threats.

Conservation Actions

The range of the species includes Parque Nacional Natural Sierra Nevada de Santa Marta. Surveys are needed to determine the current population status of this species. Disease management and captive-breeding programmes are recommended.
