As printed (Eq. 2, p. 4)
ln(Y) = ln(a) + b ln(X)
In this library's units, ready to compute (kg)
Aboveground biomass = exp(-1.852 + 2.378 * ln(D))D- Diameter at breast height (1.3 m), cm
ln(Y) = b0 + b1 ln(DBH), natural log, no correction factor stated in the paper. Aboveground biomass includes foliage and small branches (trunk and crown sections were summed).
