- S8548 - Perennou et al. (1994) estimated the population size at 350,000 individuals. Maximum counts were 409,182 and 469,312 individuals in 2003 and 2004, when a major survey took place in Central Asia and the Caspian region (Solokha, 2006). The average count total was 88,727 individuals during the period of 2008-2012. Sum of the 5-year means was 193,118 individuals during the same period. However, important numbers were missed from TM (up to 52,395 individuals in 2004), UZ (up to 42,714 individuals in 2004), KZ, (up to 7,735 in 2004), TJ (up to 10,226 individuals in 2004), plus a couple of thousands in IQ and AM. This suggests a population size over 300,000 around 2004.
- T6542 - It was not possible to include data from the period before 2003 because less than 30% of the totals were based on real counts. The results of the trend analysis show a large decrease. However, it is very likely that this apparent large decrease is partly due to reduced efforts instead of genuine population changes. This is supported by the fact that only a very small decrease can be detected in AZ and IR with regular monitoring activities.
