Population justification: The global population is estimated to number 2,000,000-2,600,000 individuals (Wetlands International 2006), while national population estimates include: c.50-1,000 individuals on migration and < c.50 wintering individuals in China; c.50-1,000 individuals on migration and < c.50 wintering individuals in Taiwan and c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Russia (Brazil 2009).
Trend justification: The overall population trend is decreasing, although some populations have unknown trends (Wetlands International 2006).
