Population justification: The population is estimated at 2,352-4,704 (6-12 individuals/km2 x 392 km2 [45% EOO]), i.e. perhaps best placed in band 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals. Density from that recorded for congener Chlorocichla flaviventris, and up to the lower quartile of three estimates of eight African greenbuls. However, further surveys are required to get a better estimate of population size, and it could number only 250 individuals.

Trend justification: The population is suspected to be in rapid decline, owing to habitat loss and degradation.
