This study was conducted to analyze grazing pressure on change in species diversity , quantity and quality of species composition , and also change in canopy cover of different plants group of outside and inside of exclosure in Bouralan of Makou .Vegetation and soil were sampled in four slope and aspect classes on 16 transects with 160 plots based on systematic – ramdom method. Location of each sample was recorded using global positioning system. Slope and aspect maps were produced .Soil samples were collected from 0-30 cm depth and analysed in the lab. Using a 1*1m plot canopy cover of each species , and density . litters , stone and bare soil were also estimated using this plot. Plant species were collected in one growing season , and using literature was identified . Diversity indices such as Shannon Wiener , Simpson and Briluin ;
