In this library's units, ready to compute (kg)
Foliage biomass = 0.0003 * D^2 * HD- Diameter at breast height (1.3 m), cm
H- Total tree height, m
W = dry weight in kg (Table 7 in kg), D = DBH in cm, H = tree height in m. The paper prints no correction factor, so none is applied. DBH 5.9-38.7 cm and height 6.6-26.6 m are the min and max of the per-site ranges in Table 6 (Suwon, Jangseong, Gangjin; ages 8-34 years).
