Due to the lack of sufficient knowledge on other potential and capabilities of rangelands, they are overgrazed to provide livestock feed. This is the ignorance of many aspects of benefites one can make of rangeland’s species. Chhar-Bagh summer rangelands have high diversity in terms of medicinal plants. The aim of this therefore, is to study the potential of medicinal, industrial and ediblability of the plants in Chhar-Bagh summer rangelands, Golestan Province. Which will endup with multiple and more sustainable use of the rangelands. Final rangeland’s suitability map for 2015, which is the combination of the vegetation and environmental factors, was generated as the result of the study using the overlay function in the Geographic Information System's environment and by incorporating the limiting factor in each polygon. Samplis were taken from different vegetation types (each as a work-unit) by establishing 3 transect of 100m length based on the Randomized-Systematic method. Alongside of each transect the following factors were considered: species frequency, canopy cover and composition. Production of the medicinal, industrial and edible plants were also recorded in quadrats adjusted to the type of vegetation in the area. The results showed that from 184 plant species identified, 87 species are categorized as medicinal, industrial and/or edible plants. These species belong to 26 families, of which Lamiaceae, Astraceae and Fabaceae with 22, 19 and 10 plants species respectively had the highest frequencies. Having three classes of suitabilities, outcome of the suitability model showed that the potential of 2.72 % (221.02 ha) are high (S1), 57.7 %( 4686.72 ha) are medium (S2), 24.28 % ( 1972.89 ha) low (S2) and 15.3% (1242.84 ha) are non suitable lands for usage of medicinal and/or industrial and ediabilities. Generally, Production economic index and percentage of medicinal plant composition are positive factors for the total suitability assessment, while slope gradient and the mountainous nature of the region are among the limiting factors. The results showed that economic benefits of medicinal plants not only mitigates the process of overgrazing but also improves the general economic status of the local peoples.
