Notes

  • T810 - 700: Modelled counts in NW Europe decreased from 39,000 to 32,000 between 1989 and 2002. The small W Mediterranean wintering population also decreased.
  • T4174 - D.Unterkofler proposed trend DEC? 2003-2012 based on Andres, B et. al. 2012.
  • T812 - 898. Trend 1983-2007: +2.0% p.a. – Increase. However, trend in African part of range poorly known
  • T811 - 914. Decreases in NW Europe and W Mediterranean have levelled off.
  • T6332 - Based on the IWC data, a moderate decline in the 1990s was followed by a strong increase in the early 2000s (Nagy et al., 2014, van Roomen et al. in prep). This pattern concerning the 1990s consistent with what is described in (Delany et al., 2009). Since the early 2000s counts reported to the IWC have increased from some 10,000 individuals to 25,000 in FR and also increased in ES and NL (European Topic Centre on Biological Diversity, in prep.). There is no current trend data available from GL and (Andres et al., 2012) refers back to the now outdated WPE4.
