Population justification: A conservative estimate of primary rainforest cover in Madagascar is c.40,000 km2 so even at 0.1 individuals/km2, a low population estimate would be 4,000 individuals (F. Hawkins in litt. 2009). It is placed in the band 2,500-9,999 mature individuals, equating to 3,750-14,999 individuals, which is rounded to 3,500-15,000 individuals here.

Trend justification: The population is suspected to be declining at an unquantified rate owing to the destruction and degradation of its habitat through clearance for subsistence cultivation, commercial logging and uncontrolled fires. An increasing human population is putting pressure on the remaining habitat (Du Puy and Moat 1996). Modelling the possible effects of climate change have shown that this species's ecological niche may decline by as much as 72% due to climate change over the 50 year period from 2000-2050 (Andriamasimanana and Cameron 2013). Assuming a linear decrease, this would equate to a c.34% decline in its ecological niche over its next 3 generations, provisionally placed here in the range of 30-49% (c.23% in next 2 generations; c.11% in next generation).
