Tecoma stans / Aboveground biomass
Total aboveground biomass, Tecoma stans var. stans, dap only
© Robert Taylor · CC BY · iNaturalistAs printed (Cuadro 9 / Resumen / Conclusiones)
In this library's units, ready to compute (kg)
Aboveground biomass = exp(-2.9409 + 2.6925 * ln(D))D- Diameter at breast height (1.3 m), cm
Ln is natural log as printed; the Discusión notes that back-transformed log models underestimate but gives no correction factor, so none is applied. Biomass is oven-dry (103 °C) total aboveground (stem + branches + leaves), kg/tree; dap in cm, ht (total height) in m. DBH and height ranges are from Cuadro 2 (descriptive statistics of the sampled trees). Trees from a managed plantation at 2 x 2 m spacing, used to inform urban green areas. Cuadro 9 prints the slope as 2.6935; the abstract, results text and conclusions print 2.6925, which is used here.

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 = 8 | 14.3 | 14.3 | Computed from the printed form hand-computed from the published form |
| D = 15 | 77.5 | 77.5 | Computed from the printed form hand-computed from the published form |
