In this study, ecological conditions were investigated in five criteria; climatic, topography, geomorphology, soil and land use, with the defined sub-criteria in order to determine the most important factors in locating the capable dry farming lands and determining the priority areas for planting. Then a questionnaire was designed and completed by 10 experts to give score the criteria and sub-criteria. The results showed that among the main effective factors, the topography and the climate had the highest effects, respectively, with a weight of 0.43 and 0.26, and soil and land use factors are the next priorities. The geomorphologic factor has the lowest effect of 0.60 weights. After preparing the base maps, these layers and weights of the network analysis process model were combined together with GIS and the restore potential map was obtained in five classes. The results showed that 19165 hectares of low-yielding and abandoned dry-farming lands (35.32%) have the highest potential for restoration. The lowland area is 3445 hectares and 5.81 percent has very low potential. In general, according to the results, 75.54 percent of these lands have a medium to the high potential for restoration. This percentage represents higher capacity and efficiency of the region to range planting and rehabilitation of low yielding and abandoned dry-farming lands. Therefore, this method can be used in determining the most suitable dry-farming lands for restoration and forage planting and returning these lands to rangelands so that the success of the development projects of the dry-farming lands is further enhanced.

The aim of this study was to investigate the canopy cover and seed production of medicinal-economic Sumac (Rhus coriaria) seeds and locating susceptible areas of Sumac in rangelands of Khakriz village, Bilesavar County, Ardabil province. For this purpose, three sites (a total of 60 hectares) with Sumac cover and in each site three transects were parallel and perpendicular to the direction of the slope with intervals of 100 meters, were established. Along each transect used 10 plots of five square meters with 20-meter intervals using a random-systematic sampling (a total of 90 plots) and the position of each plot was recorded using GPS. Sumac seeds in each plot were harvested by clipping and weighted method. Maps of environmental factors (elevation, slope, aspect, annual precipitation, and temperature) created using digital elevation models (DEM) in ArcGIS and then values of each environmental factor extracted for each Sumac site and the questionnaire of ratings were completed in this regard. Then, to determine the areas susceptible to cultivating Sumac in the Khakriz rangelands, the analytic network process (ANP) method, was used. The results showed that the areas with Sumac cover had 657.88 kg/ha seed production and 263.12 kg/ha of powdered seed production. The results of ANP indicated that 157.12 hectares of the area were very suitable, 138.10 hectares were suitable, 110.60 hectares were medium, 46.01 hectares were poor and 46.17 hectares were unsuitable for Sumac cultivating. The results can be used to exploit, cultivate and increase the cover of Sumac in specified areas. Manuscript profile
