Population justification: The 2004 Asian Waterbird Census estimated the population in Korea at 455,000 individuals (D. Li in litt. 2005; Wetlands International 2006). A separate study in 2004 reported 658,000 individuals in Korea (Hansoo Lee in litt. 2004), but this could be an over-estimate. Further to this, Brazil (2009) has estimated national population sizes at <c.100 breeding pairs and c.50-10,000 wintering individuals in China and c.10,000-1 million breeding pairs in Russia.

Trend justification: Surveys conducted every January since 1999 indicate a rapid and consistent increase in the numbers wintering in South Korea (Moores et al. 2010, N. Moores in litt. 2010), accompanied by increases in the species's range and population in China in recent years (Lei Cao and M. Barter in litt. 2010) and possibly a slow increase in Japan since the 1990s (Hironobu Tajiri in litt. 2011).
