Appendix F (Table F1). Allometric equations used to estimate aboveground biomass (AGB).  D = diameter (cm) at breast height (1.3 m from roots) or above buttress, H = height (m), ρ = wood density (oven-dry weight / green volume, cm3).  References are (1) Asner et al. (2011), (2) Saldarriaga et al. (1988), (3) Schnitzer et al. (2006), (4) and Chave et al. (2005).  Equation numbers correspond to those in Appendix G.
