Equation

As printed (Table 10 (W=aD^b))

Branch 0.003 2.758 0.796

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

Branch biomass = 0.003 * D^2.758
D
Diameter at breast height (1.3 m), cm

W = dry weight in kg (Table 7 in kg), D = DBH in cm. 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).
