Red List Category & Criteria:	Near Threatened ver 3.1
Year Published:	2004
Assessor/s:	Fernando Castro, Maria Isabel Herrera, John Lynch
Reviewer/s:	Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Contributor/s:
Justification: Listed as Near Threatened because although the species appears not to be in decline, its Extent of Occurrence is less than 5000 km2, thus making the species close to qualifying for Vulnerable.

Population Trend:	Stable

Habitat and Ecology [top]

Habitat and Ecology:	This is a nocturnal species found on medium to high level vegetation in primary cloud forest. Breeding is by direct development.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	There are currently no major threats to the species' habitat although there are plans to build a road across the Serrania de los Paraguas. This will become a major threat if the plans go ahead, and would provide access for the expansion of agricultural activities and logging.

Conservation Actions [top]

Conservation Actions:	Most of the range of this species is within the mountains of Los Paraguas, which forms a natural unit of the high Andean ecosystem. At present there is an ongoing effort to transform this area into a wildlife reserve. Other populations are inside Parque Nacional Natural Farallones de Cali. Conservation of the species' habitat is essential for its long-term survival since it is restricted to primary forest.
