Notes

  • T6034 - Wetlands International 2012. Trend 1983-2007: -3.7% p.a. ? Significant long-term decline, but most data from one country only, Iran, providing unsafe basis for regional trend.
  • T3456 - 898. Trend 1983-2007: -3.7% p.a. – Significant long-term decline, but most data from one country only, Iran, providing unsafe basis for regional trend.
  • S8535 - Sum of site-level 5-year-means of IWC counts is 107,478 for SW Asia, 19,131 individuals for E Africa for 2008-2012. Maximum count in the last decade was 168,217 individuals in 2003 and most recent high count was 109,012 individuals in 2013. The proposed new estimate of 200,000-400,000 takes into account of the incomplete sampling of the flyway and the decline. (Wetlands International, 2014). Abundant in Ethiopia and must be more numerous in Sudan than recent counts suggest; but no high numbers are expected in Sudd. Could be 20K each in TZ & KE (Dodman, 2014).
  • T6531 - Significant long-term decline (1988-2012: 0.9594±0.0063, 2003-2012: 0.8803±0.0166) based on the IWC data from 24 countries (Nagy et al., 2014). However, majority of the counts from IR and AZ and the rest of the flyway is under-represented, thus range shift cannot be ruled out although that should be visible in the counts in AZ. Large counts in the mid-2000s may influence the rate of change in the short-term, but the significant long-term decline is clear even when these counts are discounted.
  • T6943 - In the context of longer time series the trend is rather fluctuating then being in significant long-term decline.
