Resumo: The article "Biomass Estimates for Tropical Moist Forests of the Brazilian Amazon" by Sandra Brown and Ariel Lugo (1991, this volume) presents valuable information on forest volume and biomass with a view to estimating greenhouse emissions from deforestation. Particularly important are the data these authors present from summaries of the inventories done by the RADAMBRASIL Project (Brazil, Projeto RADAMBRASIL, 1973-1983). However, adjustments are needed to compensate for a number of problems affecting the way the biomass estimate is derived and the portions of the biomass to which it applies. Some of the omitted factors tend to exaggerate biomass, while a more powerful set of factors tends to underestimate it. The net result of these is to increase the biomass estimate by over 80% for purposes of greenhouse calculations for the dense forests to which the Brown and Lugo estimate applies.
