Covers the whole genus
Equation
As printed (Table 4, model 1)
Bh = 0.0059 × Dn^2.246321
In this library's units, ready to compute (kg)
Foliage biomass = 0.0059 * D^2.246321D- Diameter at breast height (1.3 m), cm
Dn and At are diameter at breast height and total height (At measured after felling, stump height included). Adjusted R2 (not stored): stem 0.9705, branches 0.8913, foliage 0.8086, total 0.9653 (Table 4).
