Listed as Vulnerable because its extent of occurrence is 6,324 km2, it is known from fewer than ten locations, and there is continuing decline in the extent and quality of its habitat in northern Madagascar.
|Previously published Red List assessments:|
|Range Description:||This species occurs in two isolated sub-populations separated by unsuitable habitat: Montagne d'Ambre and the general vicinity of Tsaratanana, between 500 to approximately 1,000 m asl in northern Madagascar. It has now also been recorded in forest fragments between the south boundary of Montagne d’Ambre National Park and the northern boundary of Ankarana Special Reserve, between 379-563m asl (Durkin et al., 2011), and at Morapitsaka in Bemanevika Forest, between 800-1780m asl (Rabearivony et al., 2010). It is likely to occur more widely, including in Forêt d'Ambre Special Reserve, but the current estimate of extent of occurrence (EOO) is 6,324 km2.|

|Population:||It is a very common species. However due to ongoing declines in the extent and quality of habitat, the population is suspected to be decreasing.|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It is a species of humid rainforest, surviving only in slightly modified habitats. It breeds by larval development in streams.|
|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.|
Its forest habitat is receding due to subsistence agriculture (including livestock grazing), timber extraction, charcoal manufacture, the spread of invasive eucalyptus, and expanding human settlements.
Species in this genus have tested positive for Batrachochytrium dendrobatidis (Bd), however currently there have been no negative effects observed within amphibian populations in Madagascar suggesting the Bd strain has a low virulence level (Bletz et al., 2015).
It occurs in Montagne d'Ambre National Park, which provides relatively good protection, Réserve Naturelle Intégrale du Tsaratanana, and Bemanevika which planned for protection.
Improved protection of forest habitat and management of protected areas throughout northern Madagascar is required.
Further research is required to clarify the species' distribution, population size and trends, and is essential to fully understand the distribution, origin, type and virulence of Bd lineages found in Madagascar (Bletz et al., 2015).
