Population justification: 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). Surveys have focussed on reserves, with the species recorded in Nonggang, Bangliang, Chunxiu, Qinglongshan, and Xialei (Li et al. 2013, Yu et al. 2014, Zhou Fang in litt. 2016). Li et al. (2013) suggest the number of individuals may be >2,000 in Nonggang, Bangliang, Chunxiu and Trung Khanh (Vietnam [which was not surveyed as part of this study]), although they do also suggest the global population may be as low as 1,500 individuals. However, there does still remain suitable habitat to survey - particularly in Vietnam - and while reserves may provide the most appropriate habitat, the species may also occur outside of these. Additionally the lack of sightings of this species at certain reserves does not mean it does not occur there, as Li et al. (2013) did not find the species at Qinglongshan, when Yu et al. (2014) did. Therefore, the population size is tentatively retained within the range of 2,500-9,999 mature individuals; although this may be revised downwards with further information, particularly from Vietnam.
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.
