**15. Landuse**

Landuse of the Sarab Drainage Basin are: Cultivation, range, forest and residential areas (villages) (Figure 9). Forest makes a small part in southeastern part of the basin and consists of *Quercus*, *Ulmus* and *Acear* species. There is also hand-planted forest consisting of *Pinus* species. In semi-arid zones, there is no forest and dry-farming lands mainly consisting of wheat, barley, sunflower and watermelon are present which due to not performing fallow, lack of vegetation after harvesting, ploughing in the direction of slope and nature of loesses, they are highly erodible. Rangeland mainly consist of *Artimisia*+*Dactylis glomerata*, *Artimisia* +*Poa bulbusa*, *Carpinus*+*Artimisia* and *Poa bulbusa*+*Medicago sativa* which due to not paying attention to the season for exploitation, they are overgrazed by tribal and villagers livestock and are erodible.
