Notes

  • S8626 - IWC data suggest at least 250,000.
  • T6614 - Increases especially in Southern Africa due to the proliferation of dams; has decreased at some lakes that have become drier (e.g. in Ethiopia).
  • T7087 - Moderate decline in the short-term. Stable trend in the long-term, but it is based data mostly from ZA.
  • S9302 - The highest annual IWC count total between 2014–2018 was 54,222 individuals in 2015. The majority of these were reported from ZA (Nagy & Langendoen, 2020). Leguma et al. (2020) reported 15,000-20,000 pairs from TZ. Akankwasah et al. (2020) just 99 from UG, which is likely an underestimate. The population estimate is maintained based on Dodman (2014).
  • T7391 - Based on IWC data from six countries, Nagy & Langendoen (2020) reported a decreasing population for the periods of 1993-2015 (0.9905) and 2000-2015 (0.9808), but an increase for the period of 2006-2015 (1.047). Based on the smoothed imputed totals, the population has decreased by 13% (n.s.) in 15 years, i.e. in 3 generations. Akankwasah, et al. (2020) reported a stable short-term population trend from UG and Leguma et al. (2020) a stable one from TZ.
