Population justification: The population size is preliminarily estimated to fall into the band 10,000-19,999 individuals.  This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.

Trend justification: Despite the lack of quantitative data on trends or recent population estimates, the continuing threats posed to occupied habitats suggest that rapid population declines are likely to be occurring.
