Population justification: Extensive surveys conducted since 2008 have resulted in an estimate of 1,000-2,000 mature individuals, all in one subpopulation (Zhou Fang et al. in litt. 2010), with an estimate of 1,300 individuals in three reserves (Nonggang, Bangliang and Chunxiu) (Zhou Fang in litt. 2012), but the extent of suitable habitat implies that there are probably more than 2,500 mature individuals in total.
Trend justification: Population trends have not been quantified; however, given that its habitat is selectively logged, the species is suspected to be in decline owing to on-going habitat degradation.
