Abstract

Intensive livestock grazing pressure causes the changes in PLANT SPECIES DIVERSITY. This study focused on finding the effect of different grazing pressure levels on plant diversity. Three different sites consist of ungrazed, light and heavy grazing intensities were selected to evaluate the livestock grazing effects on PLANT SPECIES DIVERSITY in Gardaneh Zanbouri rangeland. Vegetation sampling was done by 15 plots along 3 transects. List of existing species, percentage of canopy cover and number of species were recorded in each plot. Ecological Methodology software was used to evaluate of diversity indices and Simpson, Shanon, N1 Hill and Brillouin indices were calculated. Data were analyzed by SPSS software and comparison of diversity indices between 3 different grazing intensities was done by Tukey test. Results showed that there is a significant difference between ungrazed and heavy grazed sites for all of evaluated diversity indices at p= 0.05. Simpson, Shanon and N1 Hill indices did not show any significant difference between ungrazed and light grazed sites. Also, it was revealed that there is a significant difference between light and heavy grazed sites at p= 0.05. Brillouin index did not show any significant difference between light and heavy grazed sites. In addition, no significant difference was observed between light and ungrazed sites.
