Notes

  • T3610 - 700: Population in Central Europe stable 1974-2002, decreasing moderately 1993-2002. Data quality less good in Mediterranean, but decreasing trend estimated in both East and West Mediterranean regions between 1993 and 2002.
  • T6098 - Wetlands International 2012. Trend 1983-2007: -2.2% p.a. ? Significant long-term decline.
  • T3611 - 914. Continuing long-term decrease.
  • T3612 - 898. Trend 1983-2007: -2.2% p.a. – Significant long-term decline.
  • S8547 - The previous population estimate of 800,000 individuals was established based on a a review of IWC data up to 2005 (Wetlands International, 2005) in CSR4. However, the IWC count totals have further decreased since then. The average annual count total was 239,025 individuals during the period of 2006-2010 and the total of the site-level 5-year-means was 379,385 individuals during the period of 2008-2012. Scott & Rose (1996) have estimated 600,000 birds for the Black Sea - East Mediterranean based on a peak count of 277,187 in Jan. 1993. Since then the max. count total was 442,662 in Jan. 1999. However, following that counts have decreased substantially and the average count total for this region was only 144,267 individuals. However, the 5-year mean was 285,696 individuals and with accounting for unsurveyed areas such as MD and EG, the population in this region is estimated to be in the range of 300,000-350,000 individuals. In Central Europe, the average count total is 75,116 individuals for the same period and the 5-year mean is 76,921 individuals, indicating a consistent coverage. However, this is only half of the 150,000 birds reported by Scott & Rose (1996). In the West Mediterranean, the average count total is 116,504 individuals and the 5-year mean is 140,033 with a recent peak count of 182,000 in 2008. Accounting for missing counts, the population is estimated around 200,000 individuals. Thus, the overall estimate for the population can be estimated around 570,000-630,000 individuals.
  • T6541 - The IWC trend analysis indicates a significant long-tem decline (Nagy et al., 2014). This agrees with the overall trend calculated from the trend estimates for wintering birds in ES, FR, IT, CH, AT, SI, HU, SK, GR, BG, RO, TR, CY, UA and BY (2000-2012: 0.9529-0.9950, 1980-2012: 0.9836-1.0001, European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.).
