We used the Shannon-Wiener index to evaluate the plant species diversity and the Pielou`s index for calculation of species evenness. Sorensen`s similarity index was used to evaluation of similarity between vegetation of 3 sites. The study was showed that plant diversity, richness and evenness affected by grazing intensity. Also plant species composition and cover were affected by grazing intensity.} }
