Population justification: In 2005, the population was estimated at 85-105 individuals. (L. M. J. Paguntalan in litt. 2005), roughly equivalent to 60-70 mature individuals.

Trend justification: Given that very little forest remains, the rate of population decline has likely slowed down (L. M. J. Paguntalan in litt. 2005).
