Equation
As printed (Table 4, species row and table note)
Ponderosa pine a, b, c, d, CF: −0.6616 0.8288 0.2127 0.4145 CF 1.0246; model form exp(a + bX1 + cX1² + dX2)
In this library's units, ready to compute (kg)
Aboveground biomass = 1.0246 * exp(-0.6616 + 0.8288 * ln(D) + 0.2127 * ln(D)^2 + 0.4145 * ln(H))D- Diameter at breast height (1.3 m), cm
H- Total tree height, m
AGB is total aboveground live-tree biomass (stem, bark, branches, foliage). X1 = ln(DBH), X2 = ln(HT), DBH in cm and HT in m. Species identified from the common name in Table 4 (scientific name added from the standard species symbol). Stand type is not stated. Observed ranges in Table 1 cover all trees of the species used.
