Population justification: The species is known from an island of 9,900 km² but the amount of remaining habitat within this range is small and severely fragmented. The population size is preliminarily estimated to fall into the band 2,500-9,999 mature individuals, which equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.

Trend justification: This species's population is suspected to be in decline owing to continued deforestation, driven by the expansion of agriculture, clearance for livestock, logging and mining.
