Pinus total aboveground biomass

Aboveground biomassPinus · PinaceaeMexiconaturalRead from the original paper

Covers the whole genus

Equation

As printed (Table 2, p. 12)

Wt = ΣWi

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

Aboveground biomass = (0.0291 * D^1.74165 * H^1.16614) + (0.02029 * D^1.33299 * H^0.92887) + (0.02508 * D^1.83773 * H^0.54626) + (0.05227 * D^1.28231 * H^0.43275)

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

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. Group equation for all species of the genus in the study; fit ranges not printed for the group.
