One of the main components affecting the ecohydrology is interception or loss of rainfall by plant canopy. interception of reduced effective precipitation and dry areas to prevent soil moisture. Low level of abstraction is considered as important factors in managing rangeland resources. In this study, the vegetative form, some broad-leaved plants and plant selection and method of abstraction in weight was calculated. Plants studied, based on morphological structure, following percentage of rainfall received and soil moisture levels have no impact on the hydrological cycle were returned. Cousinia sp (%0.322), Hulthemia sp (%0.348), Acanthophyllum sp (%0.939), Verbascum sp (%1.092), Sophora sp (%1.476), Astragalusparrowianus with a large volume (%1.85), Acantholimon sp (%2.52), Astragalusparrowianus with a small volume (%4.42).
