Most deserts of the world with temperate and warm climate offer potential sites for growing adopted plants. Thus greening the denuded land, desertification control; at its highest level, shall result in carbon sequestration. A case in point is extension of plant cover of the Greh Begone plain (GBP) in southern Iran with self-grown species of shrubs. The forced sedentarization of a scrubland by transhumant nomads in the GBP, with the mean annual precipitation and the class pan evaporation of 240 and 3200 mm, respectively, desertified the plain. Floodwater spreading and planting of adopted shrubs, bushes and trees have reclaimed about 3000 ha of the GBP. This research was conducted on the effects of floodwater spreading on carbon sequestration by dominant self-grown species of shrubs. The result of this study shows the carbon sequestration in floodwater spreading plot for dominant self-grown species of shrubs has been significantly more than controlled plot. This indicates the vast potential of the deserts with ephemeral floods for carbon sequestration, and the related activities that improve the well-being of the poverty stricken desert-dwellers.
