Due to the importance of rangeland planting projects in rangelands, this study was conducted to investigate the characteristics of vegetation and soil in three rangeland types under rangeland planting projects and non-rangeland planting projects in a semi-arid and mountainous region of Baladeh Noor in 2018. In each plant type, three transects with the length of 100 m were stablished and in five 1-m2 plots established in each transect, canopy cover of plants was recorded and soil sampling was done from 0 to 30 cm soil depth and soil physical and chemical were studied. In order to statistically analyze the vegetation and soil parameters between treatments was done using Tukey test and student's t-test was used for comparison between control and modified areas. The results showed that nitrogen, phosphorus, organic carbon of soil in the control and modified areas were significant differences at the level of P<0.05, and rangeland planting projects increased nitrogen (%), phosphorus(mg.kg), and organic carbon(%) of soil with average values of 0.34, 10.69, 2.48 respectively. There was a significant difference in the total canopy cover percentage of control and modified areas at the level of P<0.05. The highest Total canopy cover with average values of 70 % observed in modified areas. In this research, rangeland planting project increased the percentage of canopy cover of plants and some nutrients in the soil. The results of this research can be used in similar areas in terms of climate, soil and topographic characteristics.
