Equation

As printed (Table 2)

Ln(B) = −2.61 + 1.86∗Ln(dbh)

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

Foliage biomass = exp(-2.61 + 1.86 * 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. Table 2 prints R2 and adjusted R2 in a way that does not reconcile for this component, so r2 is left out.
