Pinus herrerae total aboveground biomass

Aboveground biomassPinus herrerae · PinaceaeMexiconaturalRead from the original paper

Equation

As printed (Table 2, p. 12)

Wt = ΣWi

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

Aboveground biomass = (0.06741 * D^2.520356) + (0.02468 * D^1.98837) + (0.05085 * D^2.03574) + (0.05437 * D^1.64335)

D: Diameter at breast height (1.3 m), cm

Equation as printed in the Table 2 system for this taxon; d is DBH in cm, h total height in m, output in kg dry mass. R² is the 10-fold cross-validation value. Total AGB is printed as Wt = sum of the four components (stem wood, stem bark, branches, foliage); the expression is that sum of the four printed equations.
