Population [top]

Population: It is an extremely abundant species.
Current Population Trend: Unknown
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: It lives in pristine and secondary rainforest, coffee plantations, and dense vegetation along roads. Although it is somewhat adaptable, it needs some shade and leaf-litter. It breeds in a foam nest in leaves on the ground, with non-feeding tadpoles in the nest.
Systems: Terrestrial

Threats [top]

Major Threat(s): High human population density and urbanization on the islands of Nosy Be and Nosy Komba are undoubtedly contributing to a reduction in the availability of suitable habitat. Any factors resulting in the loss of humid leaf-litter, such as expanding sugarcane cultivation, will be very detrimental for this species. Other possible threats include fires and pollution from agricultural pesticides.

Conservation Actions [top]

Conservation Actions: It occurs in Réserve Naturelle Intégrale de Lokobe on Nosy Be. There is a need for close population monitoring of this species given its very limited range.
