Habitat and Ecology [top]

Habitat and Ecology:It is strictly a forest species, not occurring in secondary habitats. Outside the breeding season it can be found among dead leaves on the forest floor. During the breeding season, males call from rocky areas by streams and springs in forest, especially in valley heads where there are boulders under which tiny currents of water flow. Breeding takes place in streams by larval development. The tadpoles have been described by Mapouyat et al. (2014).
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant
