Population justification: The global population is estimated to number fewer than 1,000 individuals, roughly equivalent to 700 mature individuals; although it has been suggested that it could be widespread in high altitude reserves of Sichuan (B. Anderson in litt. 2016).

Trend justification: Habitat loss and degradation are likely to be causing a slow to moderate population decline in this species.
