Planting with Atriplex canescens is a common revival methods of rangelands over more than three decades in Iran. It seems that has not been considered to ecological conditions in planting decision making and monitoring the effect of this species on soil and native species after planting. In ths study was investigated the natural reproduction of planted A. canescens in Cheper Ghoyma rangeland. Ploting method was used for achieve this goal, thus 25 plot of 100 square meters was stationed in the study area. For the easy access study area was divided into five growth area. 1111 shrubs was counted in all of the plots and 13 shrubs was natural reproduction thus natural reproduction of the study area was 6% in five growth area. One growth area had more natural reproduction that other growth area (11%). The average height from see level was the most difference between five growth areas due to the higher altitude in the area with higher natural reproduction, the reason of higher reproduction was higher altitude and got away from ground water level. The calculations was performed by SPSS software and one-way ANOVA exam. The overall conclusion was due to positive role of A. canescens in cover vegetation and grazing this species. Due to A. canescens has improved the cover vegetation and grazing in rangelands but natural reproduction of this plant was not acceptable if the death of existing plants, area will be empty and soil will be saltier than the initial state.
