Improper utilization of ranges and their destruction have always constituted a major concern of policymakers and planners of the natural resource sector in Iran. In this article, an attempt has been made to use the aggregate index of productivity of factors of production and to present a suitable econometric model for determining the economically correct size of range management projects in the ranges of the province of Mazandaran and to specify factors influencing this size. In this study, the economically suitable size of pasture units was estimated to be 165 hectares, which is much smaller than the size of rangeland turned over to those engaged in range management in the province of Mazandaran. Moreover, results obtained showed that the number of livestock kept in ranges exceeds the economically desirable number. In other words, the suitable balance is not maintained between the size of the range and the number of Livestock kept on it. For this very reason an increase in the size of the range unit managed by each range manager and a reduction in the number of livestock kept on it constitute effective measures in increasing the productivity of ranges and in preventing farther destruction of rangeland, and it is recommended that. These measures are carried out meticulously.
