Population justification: The combined total for the populations of each subspecies given in Garnett et al. (2011) is 13,500 mature individuals.

Trend justification: The population is likely to be fluctuating locally owing to the impacts of wildfires (Garnett et al. 2011), and may be decreasing overall.
