Listed as Endangered because its extent of occurrence (EOO) is 457 km2, it is known from two threat-defined locations and there is continuing decline in the extent and quality of its habitat.
|Previously published Red List assessments:|
|Range Description:||This species is apparently restricted to two small islands: Nosy Be and Nosy Komba off the north-west coast of Madagascar. It might occur on the adjacent mainland, but it has not been found there during recent surveys. It has been recorded from 0-300m asl, and its extent of occurrence (EOO) is 457 km2.|
|Range Map:||Click here to open the map viewer and explore range.|
|Population:||It is an extremely abundant species. However due to ongoing decline in the extent and quality of habitat, the population is suspected to be decreasing.|
|Current Population Trend:||Decreasing|
|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.|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||There are no records of this species being utilized.|
|Major Threat(s):||Its forest habitat is receding due to subsistence agriculture (including livestock grazing), timber extraction, charcoal manufacture, fire and expanding human settlements. 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. There is also a threat from pollution caused by agricultural pesticides.|
It occurs in Lokobe Strict Nature Reserve.
Further site protection and management is needed in the face of ongoing threats.
There is a need for close population monitoring of this species given its very limited range.
