Equation
As printed (Table 2)
Ln(B) = −3.63 + 2.37∗Ln(dbh)
In this library's units, ready to compute (kg)
Branch biomass = exp(-3.63 + 2.37 * ln(D))D- Diameter at breast height (1.3 m), cm
Ln is the natural log as printed. Published without correction factor (Table 3 compares with and without CF; the authors give the model without CF, so none is applied). dbh in cm, biomass in kg/tree.
