Notes

  • S8649 - No new data to improve estimate; January data from W & E Africa not useable because of overlap with Palearctic populations.
  • T6685 - IWC July data (Nagy et al. 2014) is too limited to base a trend on (Dodman, 2014).
  • T6817 - According to the IWC trend analysis data, the population is possibly in significant long-term decline although only partial information is available (Wetlands International 2017).
