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: Rapid habitat degradation is continuing across the species's range, and this species's precise habitat requirements suggest that it is likely to be declining at a similarly rapid rate.
