Population justification: The population is estimated to number 250-999 mature individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.

Trend justification: A very rapid population decline is suspected to have occurred over the last ten years, on the basis of the rate of decline in the extent and quality of forest. This rate of population decline is expected to continue over the next ten years.
