Population justification: The global population size has not been quantified, but given that the species is restricted to a single island of 253 km2, on which forest cover is confined to the centre of the island, the total population is presumed to be very small and is therefore placed in the band 250-999 mature 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 and logging.
