Population justification: Wetlands International (2006) estimated the global population at c.38,000 individuals, although recent documented declines mean that the true population size is likely to be smaller, and may not exceed 20,000 individuals (D. Rogers in litt. 2012). As such, the population is estimated to number 20,000-49,999 individuals. National population estimates include: < c.100 breeding pairs and < c.10,000 individuals on migration in China; < c.1,000 individuals on migration and < c.1,000 wintering individuals in Taiwan (China) and c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Russia (Brazil 2009).
Trend justification: The species has been declining steadily, at a rate of 2.4% annually in Moreton Bay between 1992 and 2008 (Wilson et al. 2011);  c.5% annually in Victoria between 1980 and 2010 (D. Rogers in litt. 2012); by over 65% in Tasmania since the 1950s (Reid and Park 2003); and by 40% across 49 Australian sites between c.1983 and c.2007 (D. Rogers et al. in litt. 2009, Birds Australia in litt. to Garnett et al. 2011). Declines seem equally worrying in North-western Australia (D. Rogers in litt. 2012). Furthermore, the population at Saemangeum has decreased by 32.6% (c.1,800 birds) between 2006 and 2008 due to the reclamation of tidal flats (Moores 2006, Moores et al. in litt. 2008). Although these sites only represent a proportion of the wintering and stopover populations, threats are widespread and are projected to cause population declines in the future (D. Rogers in litt. 2009), hence an overall decline of 30-49% over 30 years (three generations) is precautionarily estimated. Given that more reclamation is proposed within the Yellow Sea,with widespread threats elsewhere on the flyway, it is assumed the declines of 30-49% over 30 years will continue. It is possible that further analysis of available data may reveal even higher rates of decline (D. Rogers in litt. 2009).
