Equation
As printed (Table 4, model 2)
B̂i = 0.03384 * (D² * H)^0.9774
In this library's units, ready to compute (kg)
Aboveground biomass = 0.03384 * (D^2 * H)^0.9774D- Diameter at breast height (1.3 m), cm
H- Total tree height, m
R2adj 0.974. Total aboveground biomass (stem, branches, foliage, cones). No back-transformation correction factor is stated, none applied.
