This mixed property is a mountainous, steppe-like landscape located in the Altai Range, at the north-western edge of Mongolia. The two component parts – the Altai Tavan Bogd National Park and one section of the Siilkhem Mountain National Park – exhibit different habitats and preserve a rich stratification of archaeological remains. The landscape, still used by semi-nomadic herder communities, also represents the most complete sequence of altitudinal vegetation zones in central Siberia, ranging from the steppe, forest-steppe, mixed forest and subalpine vegetation to alpine vegetation. It includes habitat areas for rare and endangered species such as the Siberian Ibex (Capra sibirica), the Snow Leopard (Panthera uncia), and the Eurasian Lynx (Lynx lynx).
