Volume, biomass and carbon stocks in a seasonal semideciduous forest in viçosa, minas gerais state

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.
