Population [top]
Population: The global population is estimated to number c.1,000-25,000 individuals (Wetlands International 2006), roughly equivalent to 670-17,000 mature individuals. National population estimates include: c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in China: < c.100,000 breeding pairs and < c.1,000 individuals on migration in Korea: < c.100 breeding pairs and < c.50 individuals on migration in Japan and c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Russia (Brazil 2009).
Trend Justification: The population is suspected to be in decline owing to ongoing habitat destruction.
Current Population Trend: Decreasing
Additional data:
? Number of mature individuals: 670-17000 ? Continuing decline of mature individuals: Unknown
? Extreme fluctuations: No ? Population severely fragmented: No
? Continuing decline in subpopulations: Unknown
? Extreme fluctuations in subpopulations: No ? All individuals in one subpopulation: No
