Population justification: Wetlands International (2006) estimated the global population at c. 38,000 individuals, although a more recent update now estimates the population at 32,000 individuals (Wetlands International 2015). It is therefore placed in the band 20,000-49,999 individuals.
Trend justification: An analysis of monitoring data collected from around Australia and New Zealand (Studds et al. in prep.) suggests that the species has declined much more rapidly than was previously thought; with an annual rate of decline of 0.058 equating to a loss of 81.7% over three generations. Loss of habitat at critical stopover sites in the Yellow Sea is suspected to be the key threat to this species and given that it is restricted to the East Asian-Australasian Flyway, the declines in the non-breeding population are thought to be representative of the global population.
Local-scale declines have also been reported: the species has been declining steadily in Australia, 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 (South Korea) 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). Given that more reclamation is proposed within the Yellow Sea,with widespread threats elsewhere on the flyway, it is assumed that these declines will continue.
