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.
