Listed as Near Threatened because although its extent of occurrence (EOO) is 21,050 km2, it occurs in eight to ten locations and there is continuous decline in the extent and quality of its forest habitat outside of protected areas in the Central Cordillera of Colombia, thus making the species close to qualifying for Vulnerable.

Geographic Range [top]

Range Description:This species is known from the Departments of Tolima (Ruiz-Carranza and Lynch 1995), Caldas (Ruiz and Lynch 1995, Ruiz-Carranza and Lynch 1997), Huila (Acosta 2012) and Antioquia (Ruiz-Carranza and Lynch 1995, Suarez and Alzate-Basto 2014), on the eastern flank of the Cordillera Central, in Colombia, between 400 and 1,650 m asl (Bernal and Lynch 2008). Its EOO is estimated to be 21,050 km2 and it is considered to occur at eight to ten threat-defined locations.

Population [top]

Population:It is a common species. Most of the species' population is in subpopulations that are restricted to remnant forests and are isolated by a surrounding matrix of pastures and agricultural land uses; therefore, the population is considered to be severely fragmented. Due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:It occurs in sub-Andean forests on vegetation along streams. Eggs are laid on leaves overhanging water and when they hatch the tadpoles drop into the water below where they develop further. They require gallery forest to lay their eggs and hence are sensitive to any habitat disturbance.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade:

There are no records of this species being utilized.

Threats [top]

Major Threat(s): The major threats are habitat fragmentation and loss due to agricultural expansion, timber extraction and water pollution.

Conservation Actions [top]

Conservation Actions: Conservation Actions
It occurs within several private protected areas (La Forzosa Reserve, Ranita Dorada Reserve, Oriente, Calderas and Guarino). Other parts of its range outside of protected areas have largely been deforested, so conservation of remaining suitable habitat is needed, in addition to continued enforcement of protected areas to maintain critical forest habitat within the range. No conservation actions are currently in place for this species, but it has been reckoned as a priority species based on an analysis including rarity, richness and phylogenetic diversity (Mendoza and Arita 2014).

Research Needed
Studies on its population size, distribution and trends, and threats are needed.
