Population justification: BirdLife International (2001) estimated 250-999 individuals, however given an estimated 100 individuals in Malaysia (Li et al. 2005), 100-200 in Thailand (P. Round in litt. 2005 to Wetlands International 2006), c.100 in Myanmar (D. Li in litt. to Wetlands International 2006), unknown but low numbers in north-eastern India, Bangladesh and Sumatra and a new figure of c.1,200 individuals from Jiangsu, China (Tong et al. 2014), the population is likely to be larger than this. Thus overall the population is placed in the band 1,000-2,000 individuals, roughly equating to 600-1,300 mature individuals.

Trend justification: This species's population is suspected to be decreasing very rapidly, in line with levels of coastal wetland development throughout Asia for industry, infrastructure and aquaculture, and the degradation of its breeding habitat in Russia by grazing reindeer Rangifer tarandus. Survey data collected on the species's breeding grounds in 2010 and 2011 (per E. Lappo in litt. 2012) lend support to the suspicion of a very rapid decline and further analysis may elucidate whether the rate of decline could be more rapid than this.
