Listed as Vulnerable because its extent of occurrence (EOO) is estimated to be 8,602 km2, it is considered to occur in two threat-defined locations, and there is continuing decline in the extent and quality of its habitat outside of protected areas where it occurs in the Sierra Nevada de Santa Marta.
Previously published Red List assessments:
2004 Vulnerable (VU)

Geographic Range [top]

Range Description: This species is known only from two threat-defined locations in the Sierra Nevada de Santa Marta, in Magdalena Department, Colombia. This is a geographically distinct area where ongoing deforestation for expansion of agricultural production threatens subpopulations outside the borders of protected areas (one location), while the subpopulations within protected areas experience reduced risk of habitat loss (second location). It has been recorded between 980 and 1,790 m asl. The extent of occurrence (EOO) is estimated to be 8,602 km2.

Population [top]

Population: Little is known about the current population status of this species. A recent survey produced observations of four individuals in San Lorenzo (O. Cortés pers. comm. 2014).
Current Population Trend: Unknown
Additional data:
Population severely fragmented: Unknown

Habitat and Ecology [top]

Habitat and Ecology: It occurs on vegetation next to water sources in sub-Andean forests and cloud forests. It lays its eggs on leaves, and when hatched the tadpoles fall in to the water below where they develop further. It is known only from primary and secondary forest habitats (O. Cortés pers. comm. 2014).
Systems: Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat: Yes

Use and Trade [top]

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

Threats [top]

Major Threat(s): The major threat is habitat loss due to agriculture (both crops and livestock), as well as water pollution due to the fumigation of crops in la Cuchilla de San Lorenzo. This habitat loss is ongoing within the species' range and outside the borders of the protected areas where it occurs (O. Cortés pers. comm. 2014).

Conservation Actions [top]

Conservation Actions: Its range includes Parque Nacional Natural Sierra Nevada de Santa Marta and El Dorado Nature Reserve, which was established in 2006 (Fundación ProAves 2006). Additional habitat protection is needed outside of the protected areas and continued enforcement of these areas will be important for maintaining critical forest habitat within the range. Research is needed to better understand population trends and current threats.
