The objective of this work was to estimate the stock and the growth in volume (V), biomass (B), carbon (C) and carbon dioxide (CO2) in reserve areas of a Seasonal semideciduous forest in the Vale do Rio Doce, Minas Gerais State, Brazil. Data from the arboreous strata (DBH > 5.0 cm) survey were used, and the permanent plots were measured in 2002 and 2007, in two native areas in a medium stage (Mata 1) and medium/advanced stage (Mata2) of secondary regeneration. Based on data from the 2002 survey, species that showed the greatest percentages of volume and a minimum of five (5) individuals were selected to determine basic wood and bark densities of the trees. The average wood basic density was 0.65 g.cm-3 and bark basic density was 0.49 g.cm-3. The stocks and the growths in volume, biomass, carbon and carbon dioxide of the arboreous strata were estimated for Mata 1 and for Mata 2. Due to the fact that the forests are stage medium and advanced stages of regeneration respectively, they have different structures, stocks and growth.
