Abstract

Planning and optimal management of rangelands is important to achieve to vegetation changes in enclosure and enclosure rangelands. In this study due to the lack of sufficient research was compared the effect of each of the four methods of rangeland management on the plant composition. The study area located in the rangelands around the Bojnourd city of Northern Khorasan province and management methods including enclosure (18 years), enclosure agricultural rangelands, key and critical rangelands. Sampling was done by 1 meter Plots and random distribution. The canopy cover divided by species and studied based on growth form and life form. Results was analysed by SPSS software, One-Way ANOVA exam, Dunkan average compare and Chi-Square exam. The results showed that plant composition in enclosure and enclosure agricultural rangelands had significant difference with critical area. Key area had significant difference with other management methods. The conopy cover in order was reduced in enclosure, enclosure agricultural rangelands, key and critical rangelands. in other words, conopy cover was increased with increasing in grazing.
