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,.

Forage is the main product of rangelands. So, determining its economic value as one of the main important nonmonetary functions can help managers to improve planning and optimal utilization management of rangelands. The main purpose of this study is to estimate the economic valuation of the forage of summer rangelands in Nour-roud watershed basin in Mazandaran province. Consequently, total forage production estimated by using double method in 12 unit works. According to the heterogeneity of range forages in terms of economic and lacking organized market for transaction, have been used barely and using Replacement Cost Method (RCM). In order to homogenize the value of all forage plants, Total Digestible Nutrients (TDN) of each plant multiplied to its forage product to calculate the nutrition value of forage per rangeland unit work. According to the specified T.D.N of barely, the equivalent weight of barely, identified for each range/ha in different price scenarios (guaranteed, international and farm prices), total value of forage production calculated based on barely price. Results showed that, Forage yield equivalent to barely was estimated 276.5 kg per ha of 89826.7 usable summer rangelands. Its economic value was equivalent to 713280 Rials per hectare. Also, its average annual economic value by 3 price senarios estimated, 64.6 Milyard Rials. This amount of economic value was equal to 718900 Rials per hectare of Nour-rud rangelands. Also, the estimated forage values are only 25 percentage of total economic value of rangeland ecosystem that has been exploited as natural bequest without any investment.
