Population justification: Although this species is rare and localised, it has a very large range, and numbers are likely to exceed 10,000 mature individuals. It is thus placed in the band 10,000-19,999 mature individuals, which equates to 15,000-29,999 individuals in total, rounded here to 15,000-30,000 individuals.

Trend justification: This species is suspected to be declining rapidly, in line with rates habitat loss within its range.
