Ecotourism, as a side activity of rangeland, can be effective in improving the livelihood of rangers and will reduce the pressure on rangelands by economizing rangeland. In this study, with the aim of evaluating the potential rangelands of Dermian , for ecotourism use, based on environmental and ecological factors (climate, topography, soil, distance from water sources and vegetation attractions) and infrastructure (distance from the city and from roads), was done. From the combination of maps in the GIS environment and based on the FAO limiting factor approach,, the rangeland suitability was determined. Based on the results, 36.7% of rangelands are in the middle suitability category (S2), 46.5% in the low suitability category (S3) and 16.8% in the non-suitable category (N) in terms of ecotourism. In this regard, 61.5% of the rangelands for livestock grazing, have low suitability (S3) and 38.5%, unsuitable (N). The percentage of vegetation and,, the poor condition of soil erosion, are factors limiting the suitability for ecotourism and livestock grazing. , it is necessary to reduce the number of livestock and graze livestock in accordance with ecological principles; that used the rangeland of the region for ecotourism along with livestock. This, in addition to compensating for the economic problems, will also help restore vegetation. Due to the need to preserve rangeland,, forest parks can be created to accommodate tourists, up to a suitable radius of the desired rangelands, and by placing remote viewing platforms and sidewalks, from the amount of damage to vegetation and reduced soil degradation.

The role of shepherds in maintaining, managing and distributing livestock in rangelands is very important. Flock guidance plays a major role in the distribution of grazing and livestock performance in rangelands. Therefore, it is necessary to evaluate the existing spatial system and it is clear to what extent livestock are given in appropriate places according to ecological criteria and indices. The present study was conducted to evaluate the role of shepherds in herding and distribution of livestock (sheep) and its adaptation to rangeland suitability map. Record of movement of livestock in different months of the grazing season by GPS and its adaptation to rangeland suitability map which is led by shepherds in areas where the limitations of forage production and sometimes, the sensitivity of soil to erosion, have little value for why. Therefore, the hypothesis of the study that shepherd does not play an effective role in the distribution of livestock on the basis of rangeland merit is confirmed and given that shepherds have given the animals in places where they have little merit for why, it is concluded that the spatial system in the rangelands of the region is not efficient. Therefore, the use of new technologies such as GPS and electrical fences along with native knowledge in order to properly control the herd and reduce the burden of livestock grazing in the areas that are not based on ecological criteria and indicators, do not have the necessary merit, is suggested.

Rrecently, rangeland multiple use has been found to be one of the primary solutions to alleviate livestock grazing pressure while improving stakeholder's welfare and per capita income and sustainable management and development. Beekeeping in rangeland as a profitable approach and one of multiple use components in upper Taleghan basin and Saman Orfi of Narian, Dizan and Mehran were studied. The present study was aimed to determine beekeeping suitability as well as ecological and social issues. According to permanent standards and resource sites priority for comprising of these Samans Orfi reserves 4 criteria to be considered such as vegetation,environmental, physical and social issues.These criteria are included overall 14 sub criteria. So Multi-Criteria Decision Making Methods (MCDM) has used because of problem complexity. The hierarchical formed in the 4 levels that is purpose, criteria, sub criteria and options. One of the criteria were qualitative. For accessing logical results, we benefit specialist cooperation. The results showed that social problem are more important than the other criteria in priority. Also, final results of Analytical Hierarchy Process (AHP) indicated that Saman Orfi Narian, and Mehran and Dizin were fall into first to third priorities respectively.

This research was conducted to recognize Sibak-Sardab watershed rangeland potentials, evaluate and determine of suitability classes for sheep grazing. In this research, we used the proposed method of FAO (1992) and for information layers crossing used in Geographical Information System (GIS). In this research, sensitivity to erosion, water resources and forage production are three basic components of this study. We used the MPSIAC model for the sensitivity to erosion. The model of water resource suitability consists of three parameters, quantity, quality and water resource's accessibility. In the forage production model, we estimated the ratio of available forage to the whole produced forage in each vegetation type. According to the result 96% of the rangeland was in low suitability class (S3) and only 4% were in medium suitability class (S2). The most important factors causing the decrease in suitability were lower rates of available forage for the livestock, low forage production of classes, I, II and low palatability percentage. According to Actual use (22170 animal units in season grazing); and grazing capacity (15989 animal units) and also according to the high destruction because of heavy grazing; using a management method that can help to improve the rangeland condition is suggestion.
