Population justification: The global population is estimated to number c.170,000-220,000 individuals (Wetlands International 2006), while national population sizes have been estimated at c.100-10,000 breeding pairs and c.50-1,000 wintering individuals in China and c.50-10,000 wintering individuals in Korea (Brazil 2009).
Trend justification: The overall population trend is uncertain, as some populations are decreasing, while others are increasing or have unknown trends (Wetlands International 2006).
