Evaluation of anthropogenic transformation of Tuva steppe vegetation by the method of main components

The analysis of such indicators as changes in species composition, species dominance structure, plant matter reserves under the influence of different grazing regimes in the Ubsunur depression (South Tuva) shows a close relationship of all indicators of phytocenosis with pasture load. Any change in the grazing regime of phytocenosis corresponds to natural changes in its species composition, a structure of dominance and intensity of the production process.
