Abstract

Tree samples (stem, branch, leaves and roots) for biomass assessment were taken from Rhizophora stylosa plantations in Banacon Island, Bohol, Philippines. Large portion of the biomass was observed in belowground (roots) than aboveground (stem, branch and crown). Diameter and height of each tree were measured. Best-fit allometric models were formulated by correlating diameter and height values with tree biomass. Full model utilizes both diameter and height variables in allometric model formulation while reduced model solely depends on diameter values. Both forms yielded high coefficient of determination (R2) values thus indicating their reliability to predict tree biomass. Full model was however preferred over reduced model since diameter and height variables were found strong and significantly correlated with one another. To validate, actual biomass values were compared with computed values using allometric models. Results yielded no significant difference between the two sets of data hence denoting the reliability of the full models to estimate tree biomass that were grown in monoculture plantation.
