Notes

  • S8577 - Average IWC count total was 828 individuals between 2008 and 2012. The sum of the site-level 5-year means was 1,074 during the same period. The maximum count was 3,611 individuals in 2003. Scott & Rose (1996) provides justification for the population estimate although the data referred ther is now 20-40 year old. There is insuffucient information to improve on their estimates.
