Notes

  • T6091 - Wetlands International 2012. Trend 1988-2005: -2.5% p.a. ? Uncertain.
  • T3590 - 898. Trend 1988-2005: -2.5% p.a. – Uncertain.
  • S8545 - The highest IWC annual count total was 301,674 individuals in 2006, which represents the highest ever IWC count for this population.
  • T6539 - Nagy et al. (2014) analysis of IWC data suggests large decline both in the short- and the long-term (2003-2012: 0.8557±SE 0.0202, 1988-2012: 0.9602±SE 0.0106) based on 150 plots. Caution is needed because of low proportion of the real counts in the totals adjusted for missing values.
