Acacia mangium Willd. is one of the most important tree species grown in commercial plantations in Monsoon Asia. Recently, the need for accurate information on the biomass in plantations has become more urgent, especially since the amount of carbon sequestered in afforestation/reforestation Clean Development Mechanism (AR-CDM) projects in developing countries can be included under the Kyoto Protocol. The authors present here a general allometric equation for estimating aboveground biomass (AGB) of A. mangium plantations from the diameter of the trees recorded at the respective sites. Destructive samplings were conducted in plantations in Papua New Guinea (PNG), Vietnam, and Indonesia. At each site, 4-12 trees were felled, their trunks, branches and leaves were separately weighed, and allometric models for estimating AGB was determined. A general allometric equation (a log-log method) was developed from an overall total of 26 sample trees from the sampled sites. No significant differences were found between the biomass estimations derived from the site-specific and the general allometric equations. The general allometric equation may allow us to estimate AGB of Acacia mangium plantations in Monsoon Asia without destructive sampling
