Population justification:
The global population was estimated at c.11,600 individuals based on winter estimates of 1,050-1,150 individuals in China (J. Harris in litt. 2012); c.10,500 individuals in Japan (S. Chan in litt. 2012) and c.114 individuals in Korea (Li and Mundkur 2004). Recent estimates suggest there may have been an increase from 11,500 a decade ago, to an estimated 14,000 - 16,000 individuals in winter 2014/2015 (J. Harris in litt. 2016). The wide range in the current population estimate reflects the difficulty of counting the dense flocks of cranes at Izumi and the lack of recent range-wide winter counts for China (J. Harris in litt. 2016). The population is thus placed in the band for 6,000-15,000 mature individuals.
Trend justification: This species's population is suspected to be decreasing at a moderate rate, in line with levels of wetland loss and degradation in its wintering grounds, primarily as a result of reclamation for development and dam building. Based upon winter counts, it is increasing at Izumi in Japan and Suncheon Bay in South Korea but the species is declining at all seven of its other known wintering sites (S. Chan in litt. 2006). Across the whole population the past decline appears to have stabilised.
