- S8311 - The current estimate of 700,000-1,000,000 individuals is based on breeding numbers and was adopted in WPE4. Midwinter counts continue to account for some 243,000-372,000 birds, majority of which are counted in Europe (Wetlands International, 2014). National estimates for wintering birds from BE, BG, DE, DK, ES, FR, IE, IT, NL, PT, SI and UK add up to 477,095-616,956 individuals showing already a large proportion added to the numbers reported to the IWC. However, breeding numbers from AT, BE, DE, DK, EE, ES, FI, FR, HU, IE, LT, LV, NL, PL, RO, SE, SI, SK, UK add up to 163,980-185,563 pairs (European Topic Centre on Biological Diversity, in prep.). Adding to this 49,001-121,311 pairs for RU, BY, CZ, FO, RS, ME and UA (BirdLife International, 2004) yields a total estimate of 212,981-306,874 breeding pairs, i.e. 640,000-920,000 individuals, which is only slightly different from the existing estimate.
- T6311 - The moderately increasing long-term trend based on the IWC data (Nagy et al., 2014 and van Roomen et al, 2014) agrees with the overall long-term (1980-2012: 1.0020-1.0081) trend based on national trend estimates for wintering birds in BE, BG, DE, DK, ES, FR, IE, IT, NL, PT, SI and the UK (European Topic Centre on Biological Diversity, in prep.). However, the results of Nagy et al. (2014) and van Roomen et al. (2014) are marginally more positive than the overall short-term trend calculated based on national estimates (2000-2012: 0.9984-1.0018). This can be caused by the relatively high proportion of imputing to account for the missing counts from ES in 2011 and 2012. On the other hand, the overall trend of the breeding population (without data from RU, and some other countries with small breeding populations) shows decline both in the long- and the short-term, which contradicts increasing trend suggested by wintering numbers. Opposing trends in wintering numbers in Europe and Africa (van Roomen et al., 2014) would support the assumption of range shift, but wintering numbers along the coast of W and NW Africa were always far less than in Europe and immigration from Africa to Europe cannot explain the increase in Europe. Therefore, a STA/DEC assessment is adopted here.
- T7116 - Both BirdLife International (2015) and and EBCC et al. (2016) show declining trend in breeding birds both in the long- and the short-term. However, mid-winter counts suggest strong increase in the long-term and stable trend in the short-term (Wetlands International, 2017). In concordance with van Roomen et al. (2015), the estimate based on the breeding season is considered to be more reliable than the trends based on more variable mid-winter counts, therefore the assessment of van Roomen et al. (2015) is accepted.
