For this research, four sites with different characteristics (Dasht Abkan, Artesh, Dorahi Kosheh and Scale Abad regions of the Khash city in southeastern part of Iran) were selected, and the one hectare land of the research area at each location was fenced. Twenty 1 m x 1 m plots were randomly (completely randomized design) selected at each site. One soil sample was taken from the 0-45 cm depth at each location and analyzed for pH, EC, ESP, CaCO3, organic carbon, potassium, nitrogen, phosphorus and calcium. Rainfall was collected daily and measured at each location. The parameters measured included canopy surface area, plant height, litter, stem density, bare soil area and rock cover percentage, number of dry species, annual forage products and number of the established plants. Although, Artemisia cover shows a poor range stand in this research area, it has a high value in dry regions, and it has been extensively grazed by goat and sheep in this region. It was a sever drought during...
