This species can be found from the western slope of the Cordillera Oriental in Colombia (Cundinamarca and Santander Departments), between the elevations of 1,750–2,400 m asl. Its EOO is 10,906 km2, which represents three threat-defined locations.
Habitat and Ecology
This species occurs in under storey vegetation near watercourses in cloud forest, and also occurs in secondary forest. Reproduction is by direct development.
This is a common species, but due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.
Habitat loss and degradation due to agriculture, both crops and cattle ranching, is a major threat.
In the 2004 assessment, the species was flagged as potentially susceptible to infection by the chytrid fungus as with other species in the genus, but there is no further information on this threat (Colombia Red List Assessment Workshop 2016).
This species occurs in Santuario de Fauna y Flora Guanentá Alto Río Fonce and the Estacion Demostrativa El Rasgon.
Red List Status
Listed as Vulnerable because its extent of occurrence (EOO) is 10,906 km2, it is known from three threat-defined locations, and there is continuing decline in the extent and quality of its habitat, and the number of locations in Eastern Cordillera of the Colombian Andes.
