  Background and Objective: Land use change causes perturbation in the ecosystem and can influence the C stocks and fluxes. In particular, conversion of forests to agricultural ecosystems, grazing lands and recreational places affects various soil properties especially soil organic carbon (SOC) concentration. The objective of this study was to investigate and compare the amount of carbon sequestration and edaphic properties of soil in both grazed and 30-year-old protected forest habitats in Tang Dalab forests in Ilam province. Method: To deactivate the topography variable, soil samples were taken from two areas of grazed and protected sites according to the same topographical conditions of geographical aspect, height and slope. In each area, 30 soil samples were taken from a depth of 0-30 cm using the randomly-systematically method. Findings: The results showed no significant difference between the percentage of lime, acidity (pH) and soil texture in the two areas. Moreover, bulk density, particle density, electrical conductivity (EC), total nitrogen (N), phosphorus (P), exchangeable potassium (K), organic carbon (OC%), organic matter (OM%) and carbon sequestration (SOC) were found to be significantly different (95%) in the two areas statistically. Discussion and Conclusion: Comparison of the edaphic properties of soil in grazed and protected sites showed a significant difference among most of the studied factors. Also The amount of soil carbon sequestration is higher in the protected forest area (60.03 ton/ha) than in the grazed forest area (41/17 ton/he). Finally, two authentic regression models with R2=0.995 and R2=0.998 were obtained in the protected and the grazed areas, respectively, for estimating soil carbon sequestration. Manuscript profile
