Abstract
This study aimed to investigate the effects of livestock grazing in the way, changing the qualitative and quantitative composition of the plant As well as the different groups of plant species density in the enclosure in Boralan area. The vegetation and soil samples and 360 plots at 18 transect method - systematic random out of the enclosure and enclosure in three annual enclosures took place. The position of each plot were recorded using a Global Positioning System. Tilt maps and directions enclosure was prepared. Using the parameters plots a square meter of canopy cover, density, percentage of dead leaves, rocks and pebbles and bare soil were measured. During the growing season and plant species samples were identified using available resources. Shanon Vynz, Brillouin and uniformity Simpson and Simpson, Camargo, Smith and Wilson nor at the species level using Ecological Methodology software version 6.2, respectively. Compare enclosure vegetation parameters using SPSS software (version 16) and The enclosure and the enclosures were analyzed using multivariate methods. The results showed that the obtained in the studied sites (enclosure) 11 dark, 24 genera and 24 species, is widespread. Inside the enclosure with 24 species, with 17 species richness is more than grazed out. Values of richness, diversity and uniformity within the enclosure is greater than the outside enclosure.
