Integrated rangeland ecosystem management is recognized as an effective strategy for improving vegetation cover, forage production, and enhancing sustainability in arid and semi-arid regions. In this study, the effects of various conservation and ecosystem restoration measures (including seeding, Transplanting, terracing combined with transplanting, contour banding with transplanting, pitting with seeding, and contour furrowing with transplanting) were investigated on vegetation characteristics and forage production in the rangelands of Vardij village, Tehran Province. Sampling was conducted systematically and randomly during the growing season using 4 m² plots along 100-meter transects. Vegetation characteristics were precisely recorded and the related data were analyzed. The results indicated that the aforementioned conservation measures had significant effects on vegetation variables, leading to a remarkable increase in vegetation canopy cover and a reduction in bare soil. The highest mean canopy cover (59.97%) and the lowest percentage of bare soil (7.93%) were observed in the transplanting treatment, whereas the control rangelands had the lowest canopy cover (23.2%) and the highest bare soil percentage (29.2%). Other methods, such as seeding and terrace transplanting, also showed positive effects on vegetation cover improvement. Regarding forage production, the transplanting treatment yielded the highest mean production (423 kg/ha), followed by seeding (367 kg/ha) and terrace transplanting (388 kg/ha). The control rangelands exhibited the lowest forage yield. These findings highlight the crucial role of conservation and restoration measures in enhancing vegetation cover and rangeland sustainability. Accordingly, it is recommended that future management plans utilize a combination of methods, including transplanting and seeding, to improve the quality and sustainability of rangeland ecosystems.

The positive economic and social effectiveness of rangeland restoration projects activates the process of sustainable development and leads local communities to sustainable prosperity. The purpose of this study is to assess the socio-economic and environmental effectiveness of restored rangelands with Atriplex canescens plantation in Mallard county, Tehran province, Iran. The descriptive-analytical research method based on questionnaire was applied within the statistical population including 65 experts, 132 pastoralists and 29 local communities. The selection of samples was random and sample size were determined using Cochran's formula for three groups of experts (55), pastoralists (99) and local communities (27). To determine the validity of the questionnaire, a group of experts were used and Cronbach's alpha coefficient was used to estimate the reliability of the questionnaire. Also, Kruskal-Wallis test was used to compare opinions of the studied statistical societies. The results of the comparison of economic, social and environmental indicators showed that A. canescens plantation had a significant effect on social index and had no effect on the other two indicators. Social- environmental effectiveness of planting A.canescens is related to increasing livestock products and improving the condition of ranching, According to pastoralists, the greatest economic, social and environmental effectiveness from planting A.canescens has been related to increasing livestock products and improving the condition of ranching, increasing the level of public awareness. In general, results of effectiveness planting from the point of view of all three groups are close to each other and they often agree on the effectiveness of planting Atriplex. This alignment in thinking of plantation will lead to success in the implementation of projects and the achievement of goals and perspective,.
