Population justification: The population was estimated to number at least 5,200 mature individuals by Roxburgh (2007) after a comprehensive survey of historical sites. This is equivalent to at least 7,800 individuals in total.

Trend justification: Roxburgh (2007) estimated that the range (no. of quarter degree grid squares occupied) appears to have declined by 25-50% since historical times, mostly in the last 20 years, owing to the loss and degradation of habitat. This process is on-going, and the population is likely to have declined at a similar rate over the same period.
