Population justification: Garnett et al. (2011) estimate that the declining northern race (monoides) has a population of less than 50 mature individuals and the southern race (brachypterus) is stable at c. 2,500 mature individuals. The overall population is therefore estimated at around 2,550 mature individuals, roughly equivalent to 3,800 individuals in total. |
|
Trend justification: The northern subspecies has decreased from c.206 pairs in 1988 to c.13 pairs in 2007 (D. Stewart in litt. 2007), and although the nominate subspecies is considered stable at present, it is projected to decline in the future as it is likely to suffer declines in its area of occupancy, quality of habitat, and the number of mature individuals and sub-populations owing to destructive fires (Garnett and Crowley 2000). |
