Equation
As printed (Table 4, model 1)
B̂i = 0.10012 * D^2.4589
In this library's units, ready to compute (kg)
Aboveground biomass = 0.10012 * D^2.4589D- Diameter at breast height (1.3 m), cm
The authors recommend this model for P. oocarpa (p. 8). R2adj 0.977. Total aboveground biomass (stem, branches, foliage, cones). No back-transformation correction factor is stated, none applied.
