Notes

  • T3507 - Trend 1974-2002 decreasing moderately; 1993-2002 increasing moderately (700).
  • T6058 - Wetlands International 2012. Trend 1983-2007: +1.1% p.a. ? Increase.
  • T3509 - 898. Trend 1983-2007: +1.1% p.a. – Increase.
  • S8265 - Total of the national wintering populations reported from BE, CH, DK, FR, IE, NL and the UK under the the EU Birds Directive Art. 12 process is 65,884-89,559 for the period of 2000 and 2012 (European Topic Centre on Biological Diversity, in prep.). However, this certainly represents some double counts. IWC count totals for the period of 2003-2012 ranged between 43,779 (2010) and 80,476 (2007) with a five year mean of 56,495 individuals (Wetlands International, 2014). Considering the lower counts in recent years, a new estimate of 65,000 individuals was adopted.
  • T6265 - Trend analysis results: 1988-2012: 1.59% increase, 2003-2012: -3.23 decline (Nagy et al, 2014). Christensen and Fox (2014) showed statistically significant declines in the proportion of young birds in samples of hunter-shot birds, which suggests that the short-term decrease is driven by poor reproduction.
  • S9078 - Total of the national wintering populations reported from BE, CH, DK, FR, IE, NL and the UK is 65,884-89,559 for the period of 2000 and 2012 (BirdLife International 2015). However, this certainly represents some double counts. IWC count totals for the period of 2003-2012 ranged between 43,779 (2010) and 80,476 (2007) with a five year mean of 56,495 individuals (Wetlands International, 2014) and 54,000-70,000 individuals between 2011 and 2015 (Wetlands International 2017). Considering the lower counts in recent years, a new estimate of 65,000 individuals was adopted.
  • T6932 - Following a strong increase until the early 2000s, the population trend showed some rapid decline until 2010. After that, however, numbers have increased again, and the short-term trend is now stable/fluctuating. In the long-term the population has increased.
