Importance for birds: Globally threatened bird species such as Saker Falcon (Falco cherrug), White-throated Bushchat (Saxicola insignis), Yellow-breasted Bunting (Emberiza aureola) and Cinereous Vulture (Aegypius monachus) occur at the site. The site also supports bird species of Eurasian high montane biome-restricted species, including Altai Snowcock (Tetraogallus altaicus), Chukar Partridge (Alectoris chukar), Alpine Accentor (Prunella collaris), Kozlov's Accentor (P.kozlowi), brown accentor (Prunella fulvescens), White-winged Redstart Phoenicurus erythrogaster and White-winged Snowfinch Montifringilla nivalis.

There also occurs Kozlov's Accentor or Mongolian Accentor (Prunella koslowi), whose breeding range defines the Mongolian mountains secondary area.

Special flora and fauna: Globally and nationally threatened wildlife species such as Snow Leopard (Uncia uncial), Siberian Ibex (Capra sibirica), Argali or Mountain sheep (Ovis ammon), Red Deer (Cervus elaphus), Lynx (Felis lynx), Pallas's cat (Felis manul), Stone Marten (Martes foina) and Siberian Marmot (Marmota sibirica) occur at the site.

Other information: Poaching and displacement of wild ungulates are the main problems of the site. Foreign hunters always hunt Argali or Mountain sheep and Siberian Ibexes, and there is no regulation for their activity and camping areas. Predators such as Grey Wolf and Snow Leopard started to attack on livestock, since wild ungulates ran away, due to herders started settling down in mountains and it causing conflict between park rangers and herders, because herders are secretly killing rare wild animals.
