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: A moderate and on-going population decline is suspected to be taking place, owing to rapid habitat loss within the lower parts of the altitudinal range of this species.
