  • 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 averagel 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.).
