The main objective of this study was to study the effective practices of rangeland improvement in the area, at different grazing sites represented by clay, sand and gardud. Three sample plots of 1x1Km were located at each site based on releve method, within each plot seven transects 100 m long each, were marked randomly in each plot. Five quadrats were located at twenty meter intervals along each transect. Quantitative and qualitative vegetation measurements were conducted at two rainy seasons (2007-2008), including plant composition, frequency, plant cover percentage, biomass productivity and carrying capacity. Ten soil samples were taken from each site for determination of soil organic matter percentage and soil seed bank and trees density was assessed using the nearest individual method, based on five points marked at 20 meter intervals along each transect. In addition to these socioeconomic aspects of rangeland use was ...
