Natural resource projects are implemented with the aim of preserving, restoring and improving the condition of vegetation, soil and water. Given the vastness of natural areas, the participation of local communities in the implementation of these projects is one of the principles of their success. Awareness of the effects and the extent to which the goals of these projects are achieved is possible through the assessment of economic, social and environmental impacts. The present study aimed to evaluate the effects of the MENARID and Carbon sequestration participatory projects, which were carried out in the form of pit seeding in the Shirin Darreh watershed from 2016 to 2018 and planting sapling in the region of Gorpan in 2014, on soil characteristics. In each of the project implementation areas and their adjacent rangelands as control areas, 10 soil samples were randomly-systematically collected from the depth of 0 to 15 cm. Soil properties, including EC, pH, SP, OC, N, K, P and BD were measured in the soil laboratory, and independent Student's t-test was used to analyze the data. The results showed that pit seeding had a significant effect on all studied soil properties except P in Taftazan, on OC and SP% in Rezqaneh and on soil OC in Arnaveh. Also, planting in Gorpan had effects on SP% and soil OC. Considering the environmental conditions of the regions and the measures taken in these projects, although the impact of such projects on soil properties requires a long time, their success rate can be increased by measures such as preparing the soil for planting, exclosure, enriching and amending of soil and monitoring the implementation of the project.
