Pinus radiata / Aboveground biomass

Radiata pine total AGB, weighted arithmetic model Eq. 17

Aboveground biomassPinus radiata · PinaceaeNew ZealandplantationRead from the original paper

Equation

As printed (Section 2.2, Eq. 17)

AGB = β0 Dβ1 Hβ2 (17)

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

Aboveground biomass = 0.0977 * D^2.0362 * H^0.3845

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

D in cm, H in m, AGB in kg. Fitted directly on the arithmetic scale, so no correction factor. Fit ranges are the pooled data (Table I overall). Eq. 18 under-predicts large trees according to the paper (Section 3.2).
