Use the following equations: (i) AGB=C(pw)DBH^2.38; or (ii) AGB=BEF*V. Where: AGB = aboveground biomass (kg), pw=wood basic specific gravity, BEF= Biomass expasion factor (Mg/m3), V = timber volume (m3), DBH = diameter at breast height (cm), C = slenderness coefficient. pw values can be found in Chave et al (2006) for most tropical tree species. The C coefficient value is between 0.20 and 0.25, depending on the tree species. BEF can be found in Brown (1997) FAO biomass booklet.
Thank you for sharing such a valuable information. Indeed it is very informative.
We use the same for calculating biomass for tree species above 10 cm DBH and Chave's equation for Below Ground Biomass. But I am facing difficulty in calculation biomass for the tree species below 10 cm and above 3cm DBH with non-destructive method, which is my main question.
