Notes

  • T6156 - Skov et al. 2011. 410,000 in Baltic Sea 2007-2009. Over 75% of this population occurred in the Baltic in the 1990s and this implies a 66% decline since the last comprehensive survey assuming a similar current distribution.
  • T3753 - 899. 410,000 in Baltic Sea 2007-2009. Over 75% of this population occurred in the Baltic in the 1990s and this implies a 66% decline since the last comprehensive survey assuming a similar current distribution.
  • S8562 - National estimates of wintering numbers across Europe add up to 681,599-804,365 individuals (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Skov et al (2011) estimated the numbers at 412,000 individuals in the Baltic. C. 142,000-219,000 individuals in PT, ES, FR, UK, IE, BE, NL and NO. Further 5,000-10,000 individuals off Morocco (Wetlands International, 2014). Adding the lower value to the total for the Baltic is close to the total estimate of 550,000, but it is possible that the population is somewhat larger. European breeding population estimates add up to 107,492-131,994 pairs, i.e. 320,000-400,000 individuals (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.), but this does not inlude birds breeding in W Siberia. Petersen (in litt. 2014) argue that the population could be up to 1.2 million birds based on simultaneous counts from Germany and Denmark.
  • T6555 - European breeding numbers indicate a stable population both in the short- and the long-term (2000-2012: 0.9899-1.0103, 1980-2012: 0.9971-1.0035). Overall trend emerging from national trend estimates for wintering birds show similar trend (2000-2012: 0.9995-1.0054, 1980-2012: 0.9859-1.0207) with decreasing trend reported only from the NL, increasing in DE, DK and the UK, stable in EE, ES, GIB, LT, LV, NO and PT, fluctuating in FR, IE, PL and SI and unknown in BE, BG, SE and TR (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.). Mostly shore based IWC counts indicate a decreasing trend, with rapid recovery from 2009, but these can be influenced by the distribution of birds. Spring migration statistics show an increasing trend until the late 1990s after which a slight decrease (Hario et al. 2009).
  • S9064 - BirdLife International (2015) estimated 682,000 - 805,000 individuals wintering in Europe. 5,000 - 10,000 individuals can be also added for Morocco (Wetlands International 2017). Petersen (in litt. 2014) has argued that the population could be up to 1.2 million birds based on simultaneous counts from Germany and Denmark, but this should be first confirmed by the analysis of the results of the Januar 2016 Coordinated Baltic Seaduck Survey.
  • T6963 - The European breeding trend is unknown in the short-term because the trend of the large RU population (93%) is unknown. The long-term trend is stable. The short-term trend based on national trends in wintering numbers is increasing and the long-term trend is unknown or fluctuating for most countries except BE, LV and ES - all with small populations, thus cannot be assessed (BirdLIfe International 2015). HELCOM (2017) reported increasing trend both for the long- and the short-term, but the JWGBIRD (Markones in litt) expressed doubts concerning the representativity of land-based counts and reassessment of the trend is pending until the availabilty of the 2016 January Coordinated Baltic Seaduck Survey. Wetlands International (2017) reported an uncertain trend.
