In order to maintain an optimal management method of desert rangelands with high heritage value, there is a need of basic knowledge for the flora of the area under study. For this purpose, sampling was carried out from fenced and un-fenced areas in Dera ghazi khan (Pakistan). Qualitative and quantitative analysis of vegetation were performed. Total number of families and their respective species were recorded. Among quantitative parameters relative frequency and importance value were calculated in the area covered with wire net fence and the open area. Data were analysed statistically. Results showed affected plants species richness as well as soil composition. Fencing proved to be a beneficial management to maintain species diversity. The result indicated significant difference in fenced and unfenced areas. Edaphic factors of both study sites also differed significantly. This difference can be attributed to grazing disturbance, and if managed properly, they can prove a valuable source for livestock with sustainable features.
