As printed (Table 11 (W=a(D^2H)^b))

Total 0.034 0.937 0.962

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

Total biomass = 0.034 * (D^2 * H)^0.937
D
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. Includes root. Total biomass includes roots (available for 21 trees); n and ranges for this equation are not printed, so they are omitted.
