Acer campestre / Aboveground biomass

Acer campestre, aboveground dry mass vs height (Model 2)

Equation

As printed (Eq. (1)/(2) and Table 2 (p. 10-11))

lnPag = a0 + a1lnH; Acer campestre: a0 = -3,195, a1 = 1,174, BaskCF = 1,84

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

Aboveground biomass = 1.84 * exp(-3.195 + 1.174 * ln(H))

H: Total tree height, m

Understory plant (small tree/shrub) under Scots pine. Output in kg: the text states kg for P; Table 1 headings say g, but the kg reading matches Table 1 ranges. Predictor is plant height H in m. Selected as the significant (p<0.05) model with the best fit among 18 species x fraction x predictor models; many others are not significant and were omitted.
