- S8527 - The current estimate of 300,000 individuals adopted in WPE3 based on 1995 and 1996 IWC counts is incorrect. Count totals during period of 1991 to 2010 have exceeded this number in 15 out of 20 years. Incomplete national totals from Europe in the EU Birds Directive Art. 12 report add up 271,309-344,673 individuals. Most of these estimates are based on January counts only, which limits the chance of double counts although not eliminate it completely. In addition, TR supports an additional 20-30 thousands individuals, GR another 50 thousands and 37,307 (2013) and 44,493 (2010) individuals were reported from North Africa. However, this might be an underestimate, because 27,956 individuals was counted in Egypt in 1989/90 (Meininger & Atta, 1994). This means that the population could consist of 422,000-506,000 individuals based on counted numbers.
- T6523 - IWC trend information shows large decline during the period of 2003-2012 following a stable period, thus the long-term (1988-2012) trend is also classified as moderate decline (Nagy et al., 2014). There is a large difference between the real counts and the totals with imputed missing values, which indicates less consistent site coverage for this population. The overall trend obtained through the EU Birds Directive Art. 12 reports indicate an increasing trend in each EU MS except BG for both periods (European Topic Centre on Biological Diversity, in prep.) and this contradicts the results of the IWC trend analysis.
- S9145 - The IWC count totals were around 245,000 - 369,000 individuals between 2011-2015 with significant gaps particularly in N Africa. Taking into account of missing counts and the rate of decline, the new population size is estimates is around 390,000-490,000.
- T6917 - Significant long-term decline.
