Population justification: The numbers of mature individuals are 3,000 cucullatus and 4,000 tregellasi. This gives a total population size of 7,000 mature individuals.

Trend justification: Ongoing population declines of 10-25% in 3 generations have been recorded in all eastern states based on monitoring and, while monitoring in the west has been less rigorous, it suggests ongoing declines which contribute to an overall decline of >10% for the whole species (Garnett et al. 2011).
