Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Needs updating
Assessor(s): Fernando Castro, John Lynch
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson, Neil Cox and Bruce Young)
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, all individuals are in fewer than five locations, and there is continuing decline in the extent and quality of its habitat on on the Western Cordillera of the Colombian Andes.

Geographic Range [top]

Range Description:This species is currently known only from the region of the type locality: Cerro Munchique on the Pacific slopes of the Cordillera Occidental, in Cauca Department, Colombia, from 2,170-2,540m asl. It might occur somewhat more widely.

Population [top]

Population: It is relatively common at the type locality.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It occurs on vegetation and next to streams inside forest and at the forest edge, and seeks refuge in bromeliads. It can occur in habitat such as páramo as long as there are bromeliads. Breeding is by direct development, with the eggs kept in the pouch of the female until hatched.
Systems: Terrestrial

Threats [top]

Major Threat(s): Although its only known locality is a protected area, cultivation of illegal crops is leading to the destruction of native habitat in some parts of the park.

Conservation Actions [top]

Conservation Actions: The type locality is entirely within Parque Nacional Natural Munchique, but there is a need to combat activities that result in the loss of native habitat within the park boundaries. More research is needed to determine if it occurs outside the vicinity of the type locality.
