The area belongs to the Saharo - Sindian region. Study of richness will help to accurate understanding of ecosystem function, conservation of gen sources, controle of environment change and success or un success of management programes. The data of species coverage, density and biomass were obtained from 60 plots in fencing area, by using systematic - random sampling method too. In this research, 139 species belong to 35 families were determined. Most of the species belonged to Asteraceae Chenopodiaceae each with 20, and then Poaceae with 16 and Fabaceae and Brassicaceae with 10 and 9 species respectively. The results showed if the area is reserved, production capacity woulde be about 755 kg/ha. For this area numerical value of Shannon and Simpson indices respectively were 2.87 and 0.92. This is because of gen resources and species evenness. Most of species are therophytes so, they will growth stagnation or elimination in end of spring. So, species richness in this area belonged to time and from spring to autom it will reach to minimum value.
