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: The species's population is suspected to be stable because access to its habitat is restricted and no immediate threats are known.
