Population justification: The population is estimated to number 3,000-5,000 individuals, roughly equating to 2,000-3,300 mature individuals.
Trend justification: There are no new data on population trends; however, the species is suspected to be declining at a slow rate, since habitat encroachment is likely to be on-going.
