Population justification: The population is estimated to number 16,000-28,000 individuals in total, roughly equating to 11,000-19,000 mature individuals (J. S. Kretzschmar in litt. 2000).
Trend justification: Declines owing to losses of mature forest through continuing logging, plantation establishment and clearing for agriculture are not so severe as previously feared, because the rate of conversion of old-growth native forest to mahogany plantations has slowed significantly; the rate of forest loss is estimated to be 0.5-0.8 % p.a (Claasen 1991), equating to 7-11% over 15 years (unpublished data from Fiji IBA project via G. Dutson in litt. 2005).
