Quantificação de biomassa e estimativa de estoque de carbono em uma capoeira da Zona da Mata Mineira

The preseant of Semideciduous Seasonal Forest in mid-secondary succession stage (capoeira) located in the Minas Gerais forest zone, in Vicosa, the State of Minas Gerais, Brazil. For the volume conversion in biomass, estimates of basic density of 10 species with higher IV (Importance Value) were obtained. The stock of carbon was determined considering that the dry biomass contains, approximately, 50% carbon. 31 tree species were registered, distributed in 29 genera and 21 families. The trees' average total biomass was 38.99 t.ha-1, which corresponded to a carbon stock of 19.50 ± 8.08 tC.ha-1. The value found is considered low when compared to other studies. Influences of prior use and edge effects may explain the low biomass and carbon stock found. The estimates obtained for the capoeira can be used as subsidies for the elaboration of afforestation/reforestation projects in the Clean Development Mechanism.
