Notes

  • T6622 - Collapse of breeding Lake Shalla.
  • T6795 - Results of the IWC trend analysis are statistically uncertain but the smoothened trend shows a strong declining tendency confirming the assertion of Dodman (2014).
  • T7468 - Based on IWC data mostly from ET and KE, Nagy & Langendoen (2020) reported an uncertain trend for the period of 1992-2012 with a stable or slightly increasing tendency (1.0138). The population has decreased strongly between 2008 and 2017 due to the collapse of the breeding colony at Lake Shalla, ET. Based on the growth rate of the last 10 years, the population is projected to decrease by 100% in 3 generations compared to the population levels in 2008. However, this might be not representative for the whole population. It is assumed that the population in TZ is stable (Leguma et al, 2020).
