Listed as Endangered because its extent of occurrence is 1,206 km2, it is known from two threat-defined locations, and there is continuing decline in the extent and quality of its habitat in northern Madagascar.

Geographic Range [top]

Range Description:This species occurs in the Réserve Spéciale de Manongarivo in northwestern Madagascar at 280 m asl, and at several localities in and around Réserve Naturelle Intégrale du Tsaratanana up to 1,300 m asl (M. Vences pers. comm. 2006). It might occur more widely in northern Madagascar, but other records of species in the Boophis mandraka group within its general range refer to other, undescribed species (M. Vences pers. comm. 2006). It is not thought to occur further east than Tsaratanana, thus its range is suspected to be genuinely restricted to the immediate region. Based on the current understanding of its range, the extent of occurrence (EOO) is 1,206 km2.

Population [top]

Population:It appears to be locally common at its type locality. However, due to ongoing decline in the quality and extent of its habitat, its population is thought to be decreasing.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It has been found in a degraded area near a small human settlement not far from areas of relatively undisturbed rainforest. Animals were calling 5-20m from water, along a fast-flowing stream, sitting 2-4m above the ground on shrubs and trees. This species presumably breeds by larval development in streams.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Use and Trade [top]

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

Threats [top]

Major Threat(s): Animals have been found at forest edges, but probably depend on nearby intact rainforest. Although most records are from protected areas, any unprotected populations, which probably exist between the known locations, are likely to be at risk from deforestation due to subsistence agriculture, including livestock grazing, timber extraction, charcoal manufacture, fire, 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).

Conservation Actions [top]

Conservation Actions: Conservation Actions
It occurs in the Réserve Spéciale de Manongarivo and the Réserve Naturelle Intégrale du Tsaratanana.

Conservation Needed
Improved protection of forest both in and outside of protected areas is required throughout the region.

Research Needed
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).
