Notes

  • T6060 - Wetlands International 2012. Trend 1998-2007: -0.6% p.a. ? Uncertain.
  • T3516 - 898. Trend 1998-2007: -0.6% p.a. – Uncertain.
  • S8537 - The sum of the site-level 5-year-means for 2008-2012 is only 69,610 individuals in SW Asia and the average annual count total is only 30,569 for the same period. The same values for East Africa are 14,934 and 5,054 individuals despite of significantly improved surveys in Ethiopia, Sudan and Kenya. However, with little information from South Sudan, Tanzania and Uganda. Overall, Dodman (2014) estimates that a minimum of 50,000 individuals might be in E & NE Africa. Taking into account the coverage of key sites and accounting for missing counts, the current numbers are unlikely to exceed the 200,000-400,000 individuals.
  • T6533 - Based on information from 228 plots from 23 countries from the flyway, there is an indication significant long-term decline (1988-2012: 0.9613±0.0087, 0.8442±0.0254). However, range shift cannot be excluded due to sporadic data from most countries other than IR and AZ.
