Population [top]

Population: It is locally abundant and was last recorded in 2010 (J. Gerlach pers. comm. November 2012).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It lives in pristine rainforest on the hills of the islands, but tolerates a degree of habitat disturbance. It has been found in human-disturbed habitats on the coastal plateau such as rural gardens and plantations; it also lives in heavily degraded rainforest. It burrows in soil, leaf-litter, and trash piles. It breeds by larval development in streams and pools.
Systems: Terrestrial; Freshwater

Use and Trade [top]

Use and Trade: There are no records of the species being utilized.

Threats [top]

Major Threat(s): Due to its adaptability to habitat disturbance, it is probably not affected by deforestation and is unlikely to be threatened.

Conservation Actions [top]

Conservation Actions: It occurs in Morne Seychellois National Park on Mahé Island, Praslin National Park on Praslin Island, Curieuse National Park on Curieuse Island, and Silhouette National Park on Silhouette Island; however, these are not effectively managed (J. Gerlach pers. comm. November 2012). Further research is needed on the species' natural history.
