Equation

As printed (Table 9, Quercus rugosa)

Br = 0.57163 × Dn^3.049264 × At^–1.74729

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

Branch biomass = 0.57163 * D^3.049264 * H^(-1.74729)
D
Diameter at breast height (1.3 m), cm
H
Total tree height, m

Table 1 sample size and ranges for this species. Adjusted R2 (not stored): stem 0.98, branches 0.85 (Table 9). Foliage and total not added (see source notes).
