Notes

  • S8574 - The average IWC count total is 235 individuals for the period of 2008 and 2012, with a maximum of 892 in 2010. The sum of the site-level 5-year means is 829 individuals.
  • T6567 - The analysis of the available IWC data indicate a large decrease in the short-term, but the long-term trend is uncertain. However, real counts made up less than 30% of the total in 14 out of 25 years. Therefore, the results should be treated with caution.
  • T6974 - Possibly significant long-term decline
