Listed as Vulnerable because its extent of occurrence (EOO) is estimated to be 8,492 km2, its population is considered to be severely fragmented, and there is continuing decline in the extent and quality of its forest and water habitats outside of protected areas in the Central Cordillera of Colombia.
2004 Vulnerable

Geographic Range [top]

Range Description: This species is known from Tolima (Falan near Mariquita), Antioquia (Anori), and Caldas Departments, between 1,100 and 2,000 m asl, in Colombia. It is believed to occur more widely. Its extent of occurrence (EOO) is estimated to be 8,492 km2.

Population [top]

Population: It is a common species in Tolima, but is thought to be uncommon in Antioquia. The species requires gallery forest for reproduction and therefore is restricted to the small remnant forests that still exist within its range. As these remnants are typically isolated by the surrounding matrix of pastures and agricultural land uses, the population is considered to be severely fragmented (O. Cortés pers. comm. 2014).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: It occurs in sub-Andean forests on vegetation alongside streams. Eggs are laid on leaves over-hanging 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

Use and Trade [top]

Use and Trade: There are no reports of this species being utilized.

Threats [top]

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

Conservation Actions [top]

Conservation Actions: It occurs in the La Forzosa Reserve and the Ranita Dorada Reserve, which was established in 2008 (O. Cortés pers. comm. 2014). Other parts of its range have largely been deforested, so protection of remaining habitat is a priority, as is the continued enforcement of protected areas for maintaining critical forest habitat within the range. Research is needed to better understand its distribution, population status and threats.
