Native areas under forest management are important in the process of carbon storage in the atmosphere, and can contribute substantially in this process and reduce illegal exploitation. The objective of this study was to evaluate the aerial carbono stock and the superficial andsubsurface layer of the Aluvial Seasonal Semideciduous Forest area altered in the municipality of Dueré, State of Tocantins. The data were monitored through the forest inventory in 2018, using a systematic sampling design in bands, where 22 samples of 20x50 m (1000 m²) were allocated in 5 bands in the study area, totaling a sample area of ​​2.2 hectares. As soil samples were collected in the 0-20 cm (superficial) and 20-40 cm (subsurface layer), 22 soil samples were collected for each layer. The determination of aerial organic carbon was used by the equation developed by Higuchi (1998). To determine soil carbon, the density of the soil was used, as well as its equivalent carbon content, at depths of 0-20 and 20-40 cm.
