Notes

  • T6547 - Trend analysis of IWC count data from 22 countries suggests significant long-term decline (1988-2012: 0.9666±SE 0.0082, 2003-2012: 0.8101±0.0198). However, range shift and the influence of small sample size (235 plots) cannot be ruled out due to sporadic coverage outside IR and AZ.
  • T6955 - Very steep short-term decline (0.7500, SE 0.0888), but range shift cannot be ruled out based on large increase in KZ and KG in 2014 and 2015. Long-term trend (1981-2015): 0.9722 (SE 0.0155) suggests significant long-term decline.
