Population justification: The global population size has not been quantified, though national population estimates include: c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in China; c.100-100,000 breeding pairs in Taiwan; c.100-100,000 breeding pairs and c.50-10,000 individuals on migration in Korea and c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Japan (Brazil 2009).

Trend justification: The overall population trend is decreasing, although some populations have unknown trends (Wetlands International 2006).
