Habitat and Ecology:It occurs in pristine and degraded forest, but usually in mature forest; it has once been recorded in an open area next to relict forest. It lives in fast-flowing, rocky streams, where it is presumed to breed by larval development.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: This species is locally used as a subsistence species.

Threats [top]

Major Threat(s): Its forest habitat is declining due to subsistence agriculture, timber extraction, charcoal manufacture, the spread of invasive eucalyptus, livestock grazing, and expanding human settlements. It is also collected for human consumption, but this is probably only a localized minor threat.

Conservation Actions [top]
