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: There are no new data on population trends; however, the species is suspected to be declining at a slow rate, owing to habitat degradation.
