Population justification: The population is estimated to number a minimum of 8,000 individuals, based on point counts at the two major sites of Menabe and Ankarafantsika. This roughly equates to 5,300 mature individuals.

Trend justification: The population is suspected to be declining rapidly, in line with habitat loss and degradation within the species's range.
