Equations / Aboveground biomass
Eucalyptus globulus total dry weight from D (Cuadro 2)
© Forest and Kim Starr · CC BY · iNaturalistAs printed (Cuadro 2, TOTAL row, p. 64)
In this library's units, ready to compute (kg)
Aboveground biomass = -35.3503 + 0.54647 * D^2D- Diameter at breast height (1.3 m), cm
Total dry weight per tree (kg) from DAP only; the paper's Grafico 1 draws it for DAP 14 to 40 cm ('dentro del rango en que la función es confiable'). The Cuadro 2 PTOT is the total of stem, bark, branches, twigs and leaves; the paper does not name stump or roots, so no exclusion is stated. Trees from three unmanaged 20-25 year old coppice-origin (monte alto) stands. The paper does not print DBH or height ranges of the fitted sample, only a table of diameter classes, so none is given. H is read as total height (HTOT): the paper's own stand-table comparison feeds DAP and HT into these functions. No correction factor is stated for the log models, so none applies here. Not additive with the other component functions, as the authors note.

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 | 183.2 | 183.2 | Computed from the printed form hand-computed from the Cuadro 2 form |
| D = 35 | 634.1 | 634.1 | Computed from the printed form hand-computed from the Cuadro 2 form |
