In recent years, many researchers have stated the importance of above and belowground interactions to better understand succession in plant communities and state and transition dynamics in rangelands. A review indicate that improved knowledge the soil´s seed bank is a key element in understanding above and belowground interactions and plant community dynamics in grazed rangelands. The aim was to study current successional theories, with special emphasis on state and transition models to

... nd rangeland ecosystem dynamics under grazing. I thoroughly reviewed 28 articles published that summarized and provided specific values on similarities between above and belowground communities to identify under grazing across different ecosystem Vegetation dynamics above and below-ground; succession states, transitions and thresholds The assessment of the relative importance of abiotic and biotic factors as well as their interactive between reliance in rangeland natural development and restoration is an continuously scientific challenge in all countries [1] . The role of biotic interaction in plant succession, especially how biotic interactions between plants, aboveground and belowground organisms work out into plant species replacement, is less well understood. Succession is the change in composition of natural vegetation over time, and the processes of colonization, competition, disturbance, senescence, and replacement determine the rate and direction of the succession. In most grassland ecosystems, grazing has been a main disturbance factor and should be considered as a driver of the successional stages [2] . Same time some comprehensive recent reviews have explicitly recognized the importance of interaction between plants and soils for underpinning ecosystem restoration. Especially successful restoration of Gantuya.
