Equation

As printed (Table 4, species row and table note)

Singleleaf pinyon a, b, c, d, CF: −0.5048 1.4016 0.8522 CF 1.0000; model form exp(a + bX1 + cX2)

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

Aboveground biomass = exp(-0.5048 + 1.4016 * ln(D) + 0.8522 * 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.

Outside the data this model was fitted on: height above the fitted 14 m. Results may be unreliable.

Shaded: the DBH range the model was fitted on. Other inputs held at the values above.
