Population justification: The global population is estimated to number 3,200,000 to 3,750,000 individuals (Wetlands International 2017).

Trend justification: Surveys of the wintering population in the Baltic sea indicate that the species has undergone a precipitous decline there, from c.4,272,000 individuals in 1992-1993 to c.1,486,000 individuals in 2007-2009 (Skov et al. 2011). There is considerable uncertainty over the trends of smaller populations in Europe outside the Baltic sea, in Greenland and Iceland and East Siberia and North America, rendering the estimation of its global trend very difficult. The European wintering population is estimated to be declining by 30-49% (BirdLife International 2015). However, the overall rate of decline is likely to approach 50% over three generations (27 years), from 1993 until 2020. The population size in winter is estimated to be decreasing by 30-49% in 27 years (three generations).
