Notes

  • S8677 - Patchy IWC data does not permit improvement of the estimate for this rather nomadic species.
  • T6867 - 2000-2015: 0.8463 (SE 0.0441) - steep decline.
  • S9554 - Patchy IWC data does not permit improvement of the estimate for this rather nomadic species.
  • T7237 - Both the short-term and overall trends are statistically uncertain but suggest an increasing population. However, it is based on a very small number of individuals. It also contradicts the previous trend assessment.
