Population justification: The population was estimated at 300 individuals in 2000. However, this is considered to be an underestimate (Liang Wei in litt. 2010, Zhang Zhengwang in litt. 2010). Based on an estimated population of 2,700 individuals in 1990, and assuming the population has declined at 50-79% over the past 15 years (three generations), the population is best placed in the band 250-999 mature individuals. This equates to 375-1,499 individuals in total, rounded here to 350-1,500 individuals. However, further surveys are urgently required to assess the true population size.

Trend justification: The population was estimated at 2,700 in 1990, and at 300 in 2000 (Chang et al. 2008). Although extrapolation from these figures would represent a decline of 96% over the last 15 years (three generations), the latter is considered to be an underestimate (Liang Wei in litt. 2010, Zhang Zhengwang in litt. 2010), and as such population declines are not considered to be so marked. However, the population is suspected to have declined very rapidly as a result of habitat destruction and hunting, and the species has apparently become increasingly rare (Liang Wei in litt. 2010, Zhang Zhengwang in litt. 2010), hence a decline of 50-79% is estimated.
