Notes

  • T1135 - 700: Decrease in NW Europe 1995-2002. 676: Also decreasing in West Africa since 1990s.
  • T4378 - Wetlands International 2012. Trend 1983-2007: +2.7% p.a. ? Increase. Well documented increase ended in mid 1990s, since when populations have decreased throughout Europe. Lack of data from Africa hampers interpretation.
  • T1136 - 898. Trend 1983-2007: +2.7% p.a. – Increase. Well documented increase ended in mid 1990s, since when populations have decreased throughout Europe. Lack of data from Africa hampers interpretation.
  • S8586 - 197,509 individuals were counted at the wintering grounds. Rounded to 200,000. The breeding range of this population is not clearly separated from the breeding population wintering in SW Asia and Eastern and Southern Africa.
  • T6579 - Trend analyses based on mid-winter counts indicate moderate increase (Nagy et al., 2014) or even large increase based on a more comprehensive dataset (van Roomen et al., 2014) in the long-term. In the short term, both analyses show stable/fluctuating trend.
  • S9047 - 197,509 individuals were counted at the wintering grounds. Rounded to 200,000. The breeding range of this population is not clearly separated from the breeding population wintering in SW Asia and Eastern and Southern Africa.
  • T6990 - Earlier increasing and stable trend turned into a short-term decline between 2006 and 2015.
