To investigate the growing conditions of medicinal plants in order to improve the growing conditions of these plants in the pastures of the Abidar Mountain, these pastures were divided into three height classes. In each of the floors, a section was considered for sampling, the lower section (lower polygon) with 1600 meters, the middle section (middle polygon) 2100 meters and the upper height (upper polygon) 2500 meters from the sea level. became. In each of the polygons, three transects were placed in parallel with 50 meters apart. On each of these transects, 10 plots were placed at intervals of ten meters, where data related to the vegetation was collected. A total of 200 medicinal species were identified in these pastures. Soil samples were collected from a depth of 0-30 cm in several plots and transferred to a soil laboratory to check the physical and chemical factors. The analyzes were performed by PC-ORD software. The analysis of variance indicated that acidity, cation exchange capacity, phosphorus, and clay content did not differ significantly among the three regions studied (P>0.05). However, electrical conductivity showed significant differences at the 95% probability level (P<0.05), while nitrogen, potassium, soil organic carbon, and the percentages of silt and sand exhibited significant differences at the 99% probability level (P<0.01). The correlation of environmental gradients and axes in CCA analysis revealed that acidity, electrical conductivity, cation exchange capacity, phosphorus, potassium, soil organic matter, and the percentage of sand had a positive correlation with axis 1, whereas nitrogen, clay and silt percentages, and altitude above sea level had a negative correlation. Regarding axis 2, phosphorus, sand percentage, and altitude above sea level showed a negative correlation, while other factors had a positive correlation. The results of this research indicated that altitude and certain soil characteristics are the most influential environmental factors in the distribution of vegetation in Abidar pastures.
