Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This diurnal species inhabits primary and secondary forest along streams. Males call next to or over small streams on roots, rocks, and leaves. It breeds, and tadpoles develop in small-forested streams. It has not been collected outside forest habitat.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): Habitat loss due to tourism disturbance and infrastructure development for human settlement is a major threat.

The cause of the observed decline is not known, although this species has recently tested positive for Batrachochytrium dendrobatidis infection (Toledo et al., 2006b).

Conservation Actions [top]

Conservation Actions: The range of the species includes several protected areas. More research into the species' Extent of Occurrence and population status is needed, in particular to try and determine what caused the apparent decline.
