Equation

As printed (Table 9, Quercus candicans)

Br = exp (−3.547008) × Dn^2.593972

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

Branch biomass = exp(-3.547008) * D^2.593972
D
Diameter at breast height (1.3 m), cm

Table 1 sample size and ranges for this species. Adjusted R2 (not stored): stem 0.96, branches 0.86, foliage 0.60, total 0.93 (Table 9).
