Abstract
The saiga antelope (Saiga tatarica) is a living symbol of the Eurasian steppes. Even in the recent past, its total number exceeded a million heads. As a commercial species, it was a source of inexpensive meat and skins for suede. The natural world range of saiga in Eurasia covers the steppe and desert ecosystems of Kazakhstan, Uzbekistan, Turkmenistan, Mongolia, as well as Kalmykia and the Astrakhan region in the Russian Federation. It is divided into two subspecies: (Saiga tatarica tatarica) the nominal subspecies and (S.t.mongolica) the Mongolian saiga, which is found only in Mongolia. In 2002, the International Union for the Conservation of Nature (UICN) classified saiga as CR-critically endangered. The purpose of this work is to analyze the saiga population dynamics on the territory of Kazakhstan and characterize possible anthropogenic, genetic and environmental factors affecting their numbers, with the rationale for approaches to conserving these animals' population in Kazakhstan. The article highlights the saiga dynamics of number and distribution over the past decade, the reasons for decline in its number, also discusses specific measures to conserve the saiga in modern conditions, because the current critical situation with saiga in Kazakhstan requires implementing a strategy for its conservation as a species of mammals fauna of the republic.
