Notes

  • T2473 - 494: Simultaneous decreases have been recorded in staging sites in Sweden and wintering sites in Germany.
  • T5690 - Ellermaa et al. 2010. Long-term trend ? Stable; Heinicke, T. In litt 2011.Trend 1999-2009 - Decline: Intensive surveys in January 2010-11 suggest decrease between 2004-5 and 2010-11 may be as much as 50%.
  • T2474 - 876. Long-term trend – Stable; Trend 1999-2009: - Decline 901:. Intensive surveys in January 2010/11 suggest decrease between 2004/5 and 2010/11 may be as much as 50%.
  • S8495 - Heinicke (2013) estimated the numbers at 40,000-45,000 based on data from 2011. However, Fox (in litt.) suggests that 2011 was an exceptional year with many geese missed through hard weather movements and he accounts for 2,500-3,000 in the western unit, 40,000-50,000 wintering in S Sweden/SE Denmark and 12,000-23,000 in Germany/Poland.
  • T6881 - -6% p.a..
  • S9182 - Heldbjerg et al. (2020) has reported 80,700 individuals for the Central Management Unit for October 2019 based on counts and an IPM. Preliminary counts for the Western Management Unit totalled at 1,377 individuals. No information is available for the Eastern Management Unit. The available estimates reported by Heldbjerg et al. (2020) are clearly much higher than the estimate provided by Heinecke et. al. (2018). However, they have estimated the size of the birds wintering in northeast Germany, northwest Poland and the Netherlands) at 15,000 birds. The information available for the Western and Central Management Units is taken as the minimum estimate. The maximum estimated by adding the old estimate for the Eastern Management Unit.
  • T7263 - The size of Central Management Unit has increased from less than 60,000 individuals based on October counts to around 80,000 birds (Johnson et al., 2020). The trend in the Eastern Management Units is unknown but its size is smaller than the increase in the Central Management Unit alone. Therefore, it is assumed that the overall population has increased in the short-term. However, the population has fallen from an estimated 100,000 in the mid-1990s (Heinecke et al. 2018). Therefore, it is still in long-term decline.
