Equations / Aboveground biomass
Pinus douglasiana and Pinus michoacana total aboveground biomass
Fitted on these 2 species: Pinus douglasiana, Pinus michoacana
As printed (Table 2, p. 12)
In this library's units, ready to compute (kg)
Aboveground biomass = (0.11997 * D^2.34448) + (0.03126 * D^1.978201) + (0.014982 * D^2.40887) + (0.01168 * D^2.148631)D- Diameter at breast height (1.3 m), cm
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. Data of the two species were combined by the authors; fit ranges not printed for the combined set.

Shaded: the DBH range the model was fitted on. Other inputs held at the values above.
On every build, the library's form and the paper's own form (in its units) must both give these values within 1%.
| Inputs | Expected | We get | From |
|---|---|---|---|
| D = 20 | 174 | 174 | Computed from the printed form computed from the Table 2 equations (sum of the four components) |
| D = 35 | 638 | 638 | Computed from the printed form computed from the Table 2 equations (sum of the four components) |
