Population justification: It appears to have declined heavily in recent years; wildfires have wiped out remnant subpopulations. The population has been estimated at c.15,307 (7,672-35,584) mature individuals (taking into account a male-skewed sex ratio), 14,300 of which are in the Murray-Sunset region (perhaps the last viable subpopulation) (Brown et al. 2009).
Trend justification: This species is suspected to be declining very rapidly, on the basis of continued habitat degradation owing to fire (Garnett and Crowley 2000).
