The cenoflora includes 176 species from 120 genera and 41 families. The hierarchical order of the leading families is as follows: Asteraceae Dumort, Poaceae Barnhart, Ranunculaceae Juss., Rosaceae Juss. Comparative analysis of life forms shows that short rhizomatous plants prevail – 33%, as taproot plants constitute 24% and tussock plants – 11%. The basis of communities in relation to the temperature, moisture and substrate structure are made of the following ecological groups of plants: mesophytes – 30%, and, in a smaller proportion, of mesohygrophytes – 19%, mesoxerophytes – 20% and mesopsychrophytes – 18%.
