Notes

  • S8532 - 811,065 individuals were still reported from January 2004, but much lower numbers afterwards. However, it is possible that range shift would be undetected in the less intensively monitored Central Asian Republics. Therefore the earlier estimate of Perenou et al (1994) is retained.
  • T6528 - Overall decline both in annual count totals and in adjusted count totals (Nagy et al., 2014). Significant long-term decline.
  • T6930 - Significant long-term decline was reported earlier. However, in the absence of adequate monitoring data from farther north in the Caspian region, it is not possible to judge whether this is a genuine decline caused by unsustainable harvest (both legal and illegal) or simply reflects range shift. Until further evidence becomes available or the trend recovers, the current asessment of significant long-term decline is retained.
