Abstract: This study aimed to examine the soil properties and amount of carbon storage in order to determine the relationship between soil factors and the occurrence of plant species. Soil samples were collected from the topsoil (at depths between 0–5 cm) and subsoil layers (at depths between 20–25 cm) across three different area types: regular fire areas, fuel management areas, and fire protection areas, for at least 10 years. In total, nine plots, measuring 40 meters x 40 meters were established to collect data related to tree species composition, while three soil samples were collected in each area. The results indicated that the areas classified under regular fire and fuel management were characterized by physical soil properties, including proportions of silt particles, clay particles, and soil moisture. The relevant chemical properties included phosphorus and magnesium. The amount of carbon stored in the biomass of all plant species was around 255.9936 and 230.1698 tons of carbon per hectare in the fire and fuel management areas, respectively. In the fire protection areas, for at least 10 years, the soil was characterized by presence of sand particles and soil hardness, with the absence of any significant chemical factors. Carbon stored in the biomass of all plant species in these areas was 196.6003 tons of carbon per hectare. Soils in fire–affected areas exhibited favorable soil texture in terms of silt and clay particle content, which contributed to better plant growth and a higher carbon storage compared to the fire protection areas, with at least 10 years of fire prevention. Therefore, it is recommended that continuous monitoring of dynamic soil and vegetation characteristics be conducted. This should include comparisons of biomass and carbon storage, as well as assessments of wildfire frequency in the study areas, to identify trends in environmental changes and native tree species. Such efforts will support a sustainable and appropriate management of forest areas
