In this library's units, ready to compute (kg)

Foliage biomass = 0.049925 * D^1.122846 * H^0.600293
D
Diameter at breast height (1.3 m), cm
H
Total tree height, m

Equation as printed in the Table 2 system for this taxon; d is DBH in cm, h total height in m, output in kg dry mass. R² is the 10-fold cross-validation value.
