Population justification: The cover of primary rainforest only in Madagascar in 2023 has been estimated at c. 25,000 km2, based on a primary forest cover in 2000 of approximately 38,500 km2 and an annual decline of 1.86% (L.-A. Réné de Roland in litt. 2023). From this, a precautionary population estimate was calculated of 1,250 to 2,500 mature individuals, using 0.2 individuals/km2, as is the density estimated in Benamevika, which is considered optimal habitat for the species, but with the assumption that habitat in the rest of the island is not as optimal or that the species is does not occupy all available habitat at such a density as in Benamevika, with a wide range of between 1/3 and 2/3 of habitat occupied (L.-A. Réné de Roland in litt. 2023). However, were all habitat occupied, the population size would reach 3,750 mature individuals. Considering this, the population size is therefore placed in the wide but estimated band of 1,250-3,750 mature individuals.
Trend justification: The species is dependent on particularly primary but also secondary forests for its survival, and although it can use open habitats for hunting, it does not breed outside of forests. Therefore, the continued destruction and degradation of these habitats through clearance for subsistence cultivation, commercial logging and uncontrolled fires, can cause a decline in the species' population size, with an increasing human population also putting pressure on the species' remaining habitat (Du Puy and Moat 1996). The current population size is therefore inferred to be experiencing a continuing decline due to the loss of suitable key habitats.
This habitat loss is supported by the estimates of forest cover loss within its range as reported by Global Forest Watch (2022, using Hansen et al. [2013] data and methods disclosed therein), which has been estimated at approximately 19% over the species' past three generations, and the past rate of decline of the species' population is suspected to be in line with the rate of decline of forest habitat and thus placed in a past decline range of 15-25%. This forest loss is projected to continue over the next three generations at a rate approximately between 18% (based on the rate of loss over the past three generations) and 29% (based on the rate of loss over the past five years [2017-2021]) (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). Therefore, again suspected to be in line with forest loss, the rate of future decline of the species' population is thus placed in the range of 15-29%, with the rate of decline having started accelerating in approximately 2012. Based on average annual forest loss rates of 2.07% between 2016-2021 (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein), the rate of forest loss within the species' range between 2016 and 2029 is estimated at between 15-29%. As the species' rate of population decline is suspected to be in step with the loss of its habitat, its rate of decline between 2016-2029 is also suspected to be within this range.
