Population justification: The size of the currently known population has not been estimated, but it is assumed here and in Garnett et al. (2011) that the number of mature individuals is in the band 50-249, but may prove to be larger.

Trend justification: The quality of the species's habitat is suspected to be in decline owing to a combination of pervasive threats.
