- S8552 - The population size was estimated by Delany et al. (1999) at 1,200,000 individuals based on the results of the IWC counts in 1995 and 1996. IWC count totals remained more or less level between 1996 and 2009. The average count total was 581,303 individuals between 2008 and 2012, while the site-level 5-year mean was 807,732 individuals. The sum of national estimates of wintering birds was 625,000-906,293 individuals (assuming that 60% of the birds in FR belong to this population) during the period of 2005-2012 (European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.) and this is roughly in line with the IWC counts. Considering the decline, the population is now estimated around 800,000-1,000,000 individuals.
- T6545 - The trend analysis based on the IWC counts suggests a large decline in this population (Nagy et al., 2014). However, this is not confirmed neither by the overall trend derived from national trend estimates of wintering birds (2000-2012: 0.9719-1.0098, 1980-2012: 0.9951-1.0055, European Topic Centre on Biological Diversity, in prep., BirdLife International et al., in prep.) nor by the trend in breeding numbers in IS, UK, IE, DK, NO, SE, FI, EE, LT, LV, PL, DE, NL, BE, FR (2000-2012: 0.9602-1.0014, 1980-2012: 0.9889-1,0012) although in both cases there is a stronger tendency towards decline. Aunins et al. (2013) has also detected moderate decline in the Baltic Sea subpopulation. Christensen and Fox (2014) have also found that long term declining trend in proportion of young birds was statistically not significant.
- T7163 - IWC trend analysis shows declining tendency in the short-term. Also see notes for CSR6. Nevertheless, the population is not in significant long-term decline.
