In recent years there has been concern about atmospheric warming due to the linear accumulation of greenhouse gases, principally carbon dioxide (CO2), in the atmosphere due to emissions caused by industrial activity and other combustion of fossil fuels. Among the many alternatives which are being currently evaluated, the offset of carbon dioxide emissions by the planting of fast-growing, CO2-absorbing, tropical forest plantations is gaining strong support. The amount of carbon sequestered by a fast-growing forest species, Eucalyptus camaldulensis, was compared with the amount sequestered by the natural regeneration of a wet-dry Savannah vegetation of northwest Minas Gerais, Brazil, known generically by the Portuguese term cerrado. A chrono-sequence study was development in five plantation stands located within a radius of 2 km of each other, all planted with the same species/seed source (i.e., second generation seed collecting area, planted with E. camaldulensis from Petford region, Queensland, Australia). Stand ages included in this study varied from 13 to 61 months old. Natural regeneration was sampled in 17 year-old secondary growth vegetation that was previously logged for charcoal, firewood and timber. Coefficients of variation for above-ground biomass of E. camaldulensis was near 10% level and over 50% for for cerrado. Root biomass showed greater variation for tap root (> 40%) and less for medium (< 30%) and fine roots (< 15%). Analysis of carbon concentrations in plant tissues (root, forest floor, stem,...
