Vegetation changes in arid areas can be one main indicator to detect land degradation and desertification. We conducted research to detect land degradation based on vegetation community change in Bayantal, Govisumber province. As a result, we illustrated that strong to moderate degree of land degradation. Main change in vegetation community was species composition and participation of specific plant species. Digression species, can adapt degraded areas, have encroached community main species and their projective cover and aboveground biomass have increased. We recorded 7 plant species commonly in desert steppe. We summarized there is strong degradation indication in Bayantal based on decrease in vegetation cover and change in species composition.
