Population justification: The species is described as fairly common to locally common in its apparently restricted range. Its population was previously estimated at 600-1,700 mature individuals; however, it has since been found at additional locations, suggesting that the population estimate should be revised upwards. The population is now placed in the band for 1,000-2,499 mature individuals, roughly equivalent to 1,500-3,800 individuals in total.

Trend justification: This species appears to be increasing locally owing to land clearance and agricultural practices (D. Lane in litt. 2013), which are increasing the availability of open scrub and wooded grassland that the species appears to favour (M. Berg and Van Kleunen in litt. 2012, S. Herzog in litt. 2013).
