| Abstract | ||
| The presentation of management models in the natural area is of great importance due to the large extent and inaccessibility of the whole surface. In this regard, Imam Kandi mountain rangelands were targeted for presenting a spatial-ecological model. Homogeneous ecological units were prepared by incorporating layers of elevation, slope, geographical orientation and plant types. Considering the ecological and environmental characteristics of each homogeneous ecological unit and considering the criteria and index for evaluating rangeland utilization, we evaluated the power and suitability of using rangelands. According to the range condition and trend of the rangeland, the rangeland method and grazing systems were presented for each of the classes. Based on the results of 23 homogeneous ecological units, it was identified that many of them belong to rangeland lands with grades 1 to 3. Accordingly, equilibrium range management was considered in 26.9% (244.4 ha) of rangelands with good condition and class 1 power. In 37.4% (346.4 hectares) with moderate condition and class 2 power, natural range management was recommended. Artificial range management or range improvement were recommended for 35.7% (329.9 ha) of poor and class 3 land. In order to prevent erosion and increase forage production, artificial range management was recommended for abandoned fields. The results indicate that application of spatial-ecological model and consequently identification of ecological homogeneous zones as management and planning units at macro level as a cost-effective method, in addition to assessing rangelands power, can enable rangeland management in proposing the rangeland method and grazing systems and assist in localization of range improvement operations. | ||
