The Khan Khentii SPA is situated in the territory of Erdene and Mongonmort soums of Tov aimag, Batshireet and Omnodelger soums of Khentee aimag, and Eroo and Mandal soums of Selenge aimag. The area encompasses 1,227,074 hectares of the rugged Khentii Mountains, stretching from just northeast of Ulaanbaatar to the Russian border. It was placed under special protection in 1992 by PMH Resolution No. 11. In 1995, it was included in the category 'strictly protected area' by Parliament Resolution No. 26. The Khan Khentii mountain range has preserved its original features and is located between Eurasian coniferous forest taiga and Central Asian arid steppe. The sources of three major river systems spring from the protected area: the Tuul which flows to Russia's lake Baikal and on to the Arctic Ocean, and the Onon and Kherlen, which flow east to join Amur before emptying into Pacific Ocean. The Khan Khentii mountain range represents basic characteristics of a natural zone and includes 5 kinds of landscapes of real taiga. It is also the ancestral home of Chingis Khaan.
