| The main objective of this paper is to present and discuss the best methods to estimate live above ground biomass in the Atlantic Forest. The methods presented and conclusions are the products of a workshop entitled "Estimation of Biomass and Carbon Stocks: the Case of Atlantic Rain Forest". Aboveground biomass (AGB) in tropical forests is mainly contained in trees. Tree biomass is a function of wood volume, obtained from the diameter and height, architecture and wood density (dry weight per unit volume of fresh wood). It can be quantified by the direct (destructive) or indirect method where the biomass quantification is estimated using mathematical models. The allometric model can be site specific when elaborated to a particular ecosystem or general that... |

| We performed a forest growth dynamics study in Acre State, Brazilian southwestern Amazon, where a 20 ha area was logged in 1992. The study was based permanent sample plots (1 ha) established in the logged area and in an unlogged forest immediately after logging operations finished. Forest dynamics parameters were assessed in terms of aboveground dried biomass (AGB). During the study period, three extreme climate events triggered a high impact on both logged and unlogged areas, producing AGB losses greater than those estimated for logging. Twenty years after logging, ingrowth and mortality rates were similar to those expected in an undisturbed forest, and AGB recovery was significantly faster in the logged areas. Forest management, when properly applied,... |

| Estudos sobre quantificação de biomassa florestal na Caatinga ganham importância diante da escassez de informações relacionadas ao tema no bioma e, em particular, no estado da Bahia. Este estudo teve como objetivo avaliar os estoques de biomassa e sua distribuição nos componentes da parte aérea de espécies florestais de maior densidade populacional e o potencial de utilização do fator de expansão de biomassa (FEB) médio para obtenção de estimativas de biomassa aérea em área de Caatinga localizada na Floresta Nacional Contendas do Sincorá, BA. A biomassa foi quantificada pelo método destrutivo. Foram selecionadas e abatidas árvores representativas das nove espécies de maior densidade populacional, distribuídas em três classes diamétricas. As quantidades... |
