Population justification: The population is placed in the band 2,500-9,999 individuals, equating to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.
Trend justification: A slow and on-going population decline is suspected, based on rates of habitat loss within its range.
