  • S8253 - The total of breeding numbers is 85,176-117,188 pairs (European Topic Centre on Biological Diversity, in prep.), i.e. 577,115-1,110,725 individuals using a multiplier factor of 3,85 (Schekkerman, 2012) to convert pairs into total individuals. Koffijberg (in litt., 2014) using a partly different dataset has estimated 692,162-1,168,407 individuals. The average of IWC counts from regularly counted sites 526,673 individuals was in the period of 2008-2012. After accounting for missing counts the average total was 897,898 individuals. This agrees well with the totals of national estimates of wintering birds which add up to 649,782-904,739 individuals (European Topic Centre on Biological Diversity, in prep.).
  • T6253 - Analysis of trends based on IWC data indicate large increase both in the long- (1988-2012) and in the short-term (2003-2012): +9.66±0.33% and +5.24±0.63% respectively (Nagy et al., 2014). Overall trends derived from national trend estimates for breeding birds (1980-2012: 1.0468-1.0712, 2000-2012: 1.0646-1.1099) and for wintering ones (1980-2012: 1.0479-1.0512, 2000-2012: 1.0556-1.1007) show similar pattern (European Topic Centre on Biological Diversity, in prep.).
  • S8881 - Point estimate is based on extrapolation from earlier estimate.
  • T6891 - Increasing trend both in the long- and short-trend confirmed by breeding population estimates (BirdLife International 2015), general IWC counts (Wetlands International 2017) and specialised goose counts (Fox & Leafloor in prep.).
  • S9177 - BirdLife International (in prep.) estimated the breeding population size at 177,925 - 266,430 pairs, or 690,000-1,000,000 individuals after rounding in BE, DE, DK, FR, NL, NO, SE, SJ. The wintering population can be estimated at 1,000,000 - 1,100,000 individuals after rounding based on data from BE, DE, DK, ES, FR, NL, NO, PT, SE (BirdLife International, in prep.) and additional data from MA (Amhaouch et al., 2020) and DZ (Nadjiba & Samir, 2020). The highest annual IWC count total between 2014–2018 was 629,534 individuals (Nagy & Langendoen, 2020). Based on the imputed IWC count totals, the population size was estimated between 709,000 and 775,000 between 2016 and 2018 (Heldbjerg et al., 2020) for the AEWA European Goose Management Platform and that figure is adopted here after rounding to two significant values.
  • T7259 - Based on BirdLife International (in prep.) it is estimated that the breeding population has increased by 48-84% in BE, DE, DK, FR, NL, NO, SE between 2009 and 2018 and the wintering population has increased by 14-58% in BE, DE, FR, NL, PT, SE in the same period. However, data from DK and ES was not available for this trend estimate. Based on IWC data, van Roomen et al. (2018) estimated that the population has increased by 4% annually between 2008 and 2016. Heldbjerg et al. (2020) has also used the IWC but substituted the IWC data with national estimates for DK, and estimated an annual growth rate of -0.7% for the period of 2009-2018. Nagy & Langendoen (2020) used an IWC dataset with updated data from DE and ES and estimated the annual growth rate at 0.8%. Based on these results the short-term population trend is stable. However, the population has increased at a very high rate in the long-term: 1976-2016: 10% (van Roomen et al., 2018), 1980-2018: 8.8% (Heldbjerg et al., 2020), 1977-2018: 10.6% (Nagy & Langendoen, 2020).
