After the USSR collapse, Saiga antelopes were excessively hunted for their horns and as a source of food in Kazakhstan decreasing the amount of living species down to 21,000 by the beginning of next millennia. The Kazakhstan government banned Saiga hunting imposing severe punishments and is actively fighting poachers in attempt to save the species.These policies and help from international organizations led to increase of the population up to around 250,000 in 2015.Unfortunately the Saiga antelope population was severely decemated as uncommonly large numbers of Saiga began to die from a mysterious epizootic illness suspected to be pasteurellosis in May, 2015. Herd fatality reached 100% once infected. More than 120,000 carcasses were found as of late May, 2015 with estimated 40% of population dead.It is worth noticing that there was massive spill of chemicals from a Russian rocket during same period. Some theories suggest that animals’ immune system got weakened by chemical poisoning and made them more vulnerable to seasonal infection outbreaks.
