The objective of this study was to estimate volume, biomass and carbon Stocks in trees (level 1), shrubs and seedlings (level 2) and litter (level 3), in a Semideciduos Seazonal Forest in Viçosa, Minas Gerais State, Brazil. Data of level 1 of approaching were obtained from 15 plots with 0.1 ha each. Fifteen plots of 25 m² and 6.25 m²were used in levels 2 and 3, respectively, located in level 1 plots. The total volume outside bark (stem + crown) was estimated in 281.51 ±105.80 m³ha-1 and 15.2% of this estimate corresponded to bark volume. The stem contributed with 80.30% of the total volume and the crown with 19.70%. The total biomass was estimated in 227.40 ± 77.81 t ha-1. Of this total, 181.48 t ha-1 (79.7%) were aboveground; 34.3 t ha-1 (15.2%) in the roots and 11.62 t ha-1 (5.1%) in the litter. The alive trees contributed on average with 82.8% of the total biomass, followed by litter (5.1%); no arborous species (4.2%); dead trees (3.5%); shrubs (2.9%); seedlings (1.5%). The total carbon stock was estimated in 108.98 ± 35.33 t ha-1. The percentile contribution was similar to found for biomass: alive trees 82.6%; litter 5.2%; no arborous species 4.2%; dead trees 3.5%; shrubs 3.0%; and seedlings 1.5%. Of the total carbon stock, 86.93 t ha-1 (79.7%) were aboveground; 16.41 t ha-1 (15.1%) in the roots and 5.64 t ha-1 (5.2%) in the litter.
