Analysis of rangeland condition's changes using of qualitative method of rangeland health(Case study: steppic rangeland of Roudshour)

Study of rangeland analysis can make to able an expert to judge the degradation of management activities and ecological changes of rangeland. In order to survey of range condition of sagebrush rangeland using the rangeland health method, the steppic rangeland of Roushour was selected. Habitat vigour for each area and survey regions were determined by using of rangeland health’s instructions which have 17 indicators to determining of regions health. Structural condition of three traits of rangeland health (soil and habitat sustain, hydrologic function and vigour of living things) was visionally determined. Non-parametric test for two independent samples was employed to compare between indicators and rangeland health’s traits of each survey region. The results have shown that each of three traits of rangeland health in the survey region is in the critical class because of overgrazing and lack of range readiness. Hence, it shows that range traits are lower than threshold which shows unhealthy condition of rangeland. This method is not a monitoring approach which uses to surveying of rangeland as same time and spatial. Then, if a ranger wants to appoint a temperary management’s decision, he can use this model to rangeland survey.
