For semigumid and semigumid-semiarid highlands of East Sayan we first characterized: one alliance, four associations, two subassociation, two variants relating to the class of ecological-floristic classification. At the upper boundary of the forest is dominated by larch woodlands (ass. Carici iljiniiLaricetum sibiricae ass. nova hoc loco). Association presented two variants: Hansenia mongholica and Empetrum nigrum. Variant Hansenia mongholica distinguished by good drainage conditions of habitats. Flat bottoms mountain hollows subgoltsy altitudinal belt and the upper part of the forest belt of alpine meadows occupied by swamped alpine meadows (. Cardamino pratensisCaricetum stenocarpae ass. nova hoc loco). Yernik tundras (ass. Cladonio stellarisBetuletum rotundifoliae ass. nov. prov.) are characteristic of subgoltsy altitudinal belt. Lichen tundras (. Carici ledebourianaeCladonietum stellaris ass. nova hoc loco) typical for goltsy and subgoltsy altitudinal belts. They are represented by two subassociations nova hoc loco: typicum and empetretosum nigri. Habitat subassociation typicum wetter. We propose a new alliance Cardamino pratensisCaricion stenocarpae all. nov. prov., which attributed to the order Violo altaicaeFestucetalia krylovianae and class Juncetea trifidi. Alliance characterizes swampy alpine meadows and meadow-tundras Altai-Sayan mountain region.
