Notes

  • S8255 - Fox et al (2010) stated that there is no sufficient data to estimate the numbers of this population. However, we retain Scott & Rose estimate because IWC and other data indicate that this might be still a valid estimate. The IWC count totals were 12,055 and 7,655 in 2003 and 2004, but count coverage is extremely low and biased with very little information from Central Asia.
  • T6256 - Fairly sporadic IWC data indicate that the decline of this population continues. Numbers counted at the Gyzylagach Nature Reserve, Azerbaijan, gradually decreased from 11,952 in 2003 to 0 in 2010-2012. At Lake Aggyol, Azerbaijan, numbers decreased from 1,450 in 2004 to 900 in 2012. National totals for Iran decreased from 2,008 in 2001 to 287 in 2012.
  • S9054 - 24,030 individuals reported from Uzbekistan in January 2017. An additional 1,350 was reported from Iran (Wetlands International 2017). This indicates that earlier figures were an underestimation. Therefore, this figure is adopted as a new minimum estimation.
  • S9187 - Based on national report from UZ (Mardonova, 2020). IWC count totals were also above 25,000 individuals in 2017 and 2018 (Nagy & Langendoen, 2020). These indicate that earlier estimates were too low.
  • T7268 - The IWC trend analysis produced trends indicating a biologically impossible increase because it is based on too few data and some large recent counts in UZ. Therefore, we assess the trend as unknown.
