Notes

  • T3326 - 700: Peak of 1,400,000 counted in 1995, since when trend has levelled off. Trend 1993-2002 stable.
  • T5979 - Wetlands International 2012. Trend 1983-2007: +2.6% p.a. ? Increase, but no increase since mid 1990s
  • T3327 - 898. Trend 1983-2007: +2.6% p.a. – Increase, but no increase since mid 1990s
  • S8264 - The total of national wintering population estimates from the EU Birds Directive Art. 12 reporting process adds up to 1,7-2 million birds. However, these estimates cover slightly different periods and some double counting. Recent IWC count totals are lower than in the mid-90s to mid-2000s. The count totals varied between 1. million and 1.4 million individuals. With imputing, that equals to 1.3-1.5 million individuals. As this is only slightly less than the earlier estimate of 1.5 million bird, that estimate was retained.
  • T6264 - Trend 1998-2012: +0.9% p.a., 2003-2012: -3.0% p.a. decline (Nagy et al. 2014). This is consistent with the results of national population trends in the UK and the NL, which holds c. 3/4 of the population (Austin et al. 2014, Horman et al. 2012). At the same time there is no evidence of simultaneous increases at the equally well monitored countries such as DE, DK or SE (European Topic Centre on Biological Diversity, in prep). Further support to the genuine decline is that significant decline in the proportion of young birds was reported (Christensen & Fox, 2013).
  • T6916 - Increased in the long-term.
