Population justification: The total population size is very difficult to guess, but it is potentially more than 10,000 mature individuals, thus a preliminary estimate in the range 10,000-19,999 mature individuals is used here. This equates to 15,000-29,999 individuals in total, rounded here to 15,000-30,000 individuals. Further documentation is required.
Trend justification: The population is suspected to be in decline owing to the degradation of the species's habitat by fires. Future declines are expected, owing to the eventual clearance of upper montane forest and shrubland for agriculture. Past and future rates of decline have not been estimated.
