Population [top]

Population: This species is noted as being uncommon across most of its range.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: It lives in montane rainforest along streams with steep gradients (Lynch and Duellman, 1973). Reproduction is presumed to occur via eggs laid on vegetation, with the tadpoles developing in the water.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Habitat destruction and degradation is a threat to this species, mainly as a result of smallholder farming activities and clear-cutting of forests. Predictions suggest that, in Ecuador, almost half of the habitats suitable for this species have been deforested (Cisneros-Heredia, 2008).

Conservation Actions [top]

Conservation Actions: Its distribution range overlaps with Parque Nacional Sumaco Napo-Galeras, Reserva Ecológica Antisana, Parque Nacional Podocarpus and Parque Nacional Llanganates.
