Evaluating the ecological and economic potential is an effective step and a suitable tool to guide the current activities and uses in the land towards comprehensive management and sustainable rural development. Identifying and evaluating the potentials of each region is a guide for achieving development in sync with nature in rural areas dependent on nature. In this study, the economic value of forage production in Rangelands of ChaharBagh village of Golestan province was investigated.Typing the vegetation cover of the region by going to the desired area and field survey and also with the help of the topographical map of the region and also by using the plan to recognize the ecological regions of the country and based on the specified floristic-physionomic classification method and sampling of each plant type. It was done randomly and systematically.6 plant types were identified in the study area. The results of the study showed that the total forage production in the pastures of Chaharbagh village is equal to 6203605 kilograms of dry forage and available fodder (sustainable forage) is equal to 1763925 kilograms. The economic value of the total forage produced in the pastures of Chaharbagh village is equal to 52,284,110,52 riyals, and the total economic value of the available forage of these pastures is estimated to be 11,904,012,960 riyals. The capacity of the total number of livestock units with efficiency and economic value was 4749 heads, and the total annual profit was estimated at 12,760,821,000 rials; therefore, the added value of animal husbandry in the studied pasture is equal to 040,747,917 rials.

With the importance of medicinal and economic of shrubs Rhus coriaria, the aim of this study was to determine the most important ecological factors affecting its distribution in its natural habitats in Mashhad rangelands. Sampling was done by systematic-random sampling method with 3 transects and 10 plots per transect and vegetation parameters and environmental factors were measured. Soil properties were sampled from the beginning and end of each transect. Statistical analyzes were performed using R software and analysis of variance, considering the normality of the data. Principal component analysis (PCA) was used to investigate the distribution of environmental factors. Results of analysis of variance of measured factors showed that there were no significant differences between percentages of sand, clay, silt and soil texture as well as percent and slope factors. Mostly distributed in eastern and southeast oriental species, loamy soil texture, slope percentage between slopes of 30-37% and soil sand percentage between 42-46%, The silt percentage is between 37 and 44% and the clay content is between 13 and 19%. The results showed that among the factors of height, annual rainfall, electrical conductivity, carbon, phosphorus, potassium, lime, acidity, mean annual temperature, there was a significant difference between the studied sites at 1% level of annual maximum and minimum annual temperature; In other words, these factors are not the most important factors of species distribution and they only differ among the studied habitats and cause differentiation of species.
