Justification of Red List category
This species has been uplisted to Near Threatened as it almost meets the requirements for listing as threatened under criteria A2abc+3bc+4abc. It has an extremely large range and six subpopulations across which trends are variable. The population trend of the largest subpopulation, islandica, is unclear as is the trend of roselaari. The rufa and canutus subpopulations have both experienced population declines. Two subpopulations use the East Asian-Australasian Flyway and have experienced significant declines owing to loss of habitat in the Yellow Sea. Should new research resolve uncertainties in the trends of several of these subpopulations the species may warrant uplisting or downlisting.
