Study of succession has taken on particular importance in the last 100 years, when the human impact spread to all biomes and regions of the biosphere. Among the natural zones of steppe and forest-steppe of Tuva, suffered the most severe anthropogenic transformation mainly due to grazing, to ploughing, influence of fire. A powerful and varied human impact on vegetation of the steppes, which are the basis of livestock in Tuva, requires study and quantification of changes in species composition and productivity communities. In this article on the basis of the results of the study revealed that, during the pastoral succession to any change of pasture plant community responds to natural changes in the species composition, dominant vegetation structure and intensity of the production process, that there is a direct correlation between the change of grazing impact and response.
