Population justification: The population is preliminarily estimated to number at least 10,000 mature individuals, roughly equating to 15,000 individuals in total. This requires confirmation.

Trend justification: The species is suspected to be declining at a slow to moderate rate, owing to logging and forest loss for agriculture.
