Abstract: 
Livestock grazing can lead to changes in plant composition. In this study, the effect of four grazing intensities including heavy, moderate, light and no grazing (exclosure) were studied on vegetation indices in order to improve management practices and proper planning for sustainable use of rangelands in Karsanak and Bardeh area in Chaharmahal & Bakhtiari province of Iran. Therefore, vegetation sampling was done to record canopy cover percentage and vegetation composition under four grazing intensities. Data were analyzed by one-way ANOVA, t-test, and ordination method (CCA) to assess vegetation changes under different grazing intensities. Results showed that plant species such as Agropyron repens, Bromus tomentellus, Astragalus effuses and Poa bulbosa were more found in exclosure and light grazing area. The major species found in heavy grazing area were Boissiera squarrosa, Echinops leiopolyceras, Sisymbrium irio and Euphorbia heteradenia. Due to the vegetation damage and reduction of palatable species, a moderate grazing is recommended in the study rangeland.
