Notes

  • S8519 - The FYM is 802 individuals for the period of 2008-2012. However, the total of national estimates of wintering populations in CH, ES, FR, IE, IS, SE and the UK is 4,047-4,265 individuals (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.).
  • T6516 - Although the trend based on the IWC shows large increase both in the short- and long-term, IWC counts are not representative enough to estimate the trends reliably. Wintering numbers declined in IE, UK and ES (i.e. the bulk of the European wintering population) and were stable in CH, SE and IS, fluctuated in FR. Overall trend for 2000-2012: 09514-0.9541 and for 1980-2012: 1.0153-1.0175 (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.).
  • S8823 - Sum of national wintering population estimates.
  • T6778 - According to (BirdLife International 2015), wintering numbers declined in IE, UK and ES (i.e. the bulk of the European wintering population) and were stable in CH, SE and IS, fluctuated in FR in the short-term, but strong increase is reported from both SE and UK in the long-term. The long-term trend is unknown in other countries. The trend based on the IWC shows large increase both in the short- and long-term (Wetlands International 2017). The IWC trend is driven largely by data from Germany (contributing more than 50% to the sample totals), which country is even not reported wintering numbers to the European Red List.
