Population [top]

Population: This is a hard species to find, and so its abundance is unclear.
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: It lives in lowland rainforest. The frogs are arboreal and aquatic spending most of their time, and breeding, in the small bodies of water that accumulate in cavities of living and dead trees. It can survive in heavily degraded forest, providing that large trees survive.
Systems: Terrestrial

Use and Trade [top]

Use and Trade:

There are no reports of this species being utilized.

Threats [top]

Major Threat(s): Despite its tolerance of habitat modification, it depends on large trees with holes that collect rainwater, and is presumably affected by ongoing forest loss.

Conservation Actions [top]

Conservation Actions: It presumably occurs in a number of protected areas.
