Pinus brutia / Foliage biomass
Pinus brutia needle biomass, Lebanon (Eq. 29)
© Zeynel Cebeci · CC BY-SA · iNaturalistAs printed (Table 3, Lebanon, Eq. 29, p. 105)
In this library's units, ready to compute (kg)
Foliage biomass = exp(0.078 + 10.665 * D / (D + 26.492) - 0.855 * ln(H))D- Diameter at breast height (1.3 m), cm
H- Total tree height, m
Printed residual standard error 0.442 and variance function coefficient δ = 0.952 (model fitted on the original scale, so RSE is not a log-scale value and is not entered as fit.rse). Total aboveground biomass = stem + branches + needles (dry). DBH-only forms are those the authors recommend for tree- and forest-level predictions. Country-specific DBH and height ranges are not printed, so none are entered. Equations using crown length (19, 21) and the crown-biomass equations (23, 24, 33, 34, 43, 44) are not included.

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 = 10, H = 8 | 3.4 | 3.4 | Computed from the printed form computed from the published form (coefficients as printed) |
| D = 25, H = 14 | 20.1 | 20.1 | Computed from the printed form computed from the published form (coefficients as printed) |
| D = 45, H = 25 | 56.8 | 56.8 | Computed from the printed form computed from the published form (coefficients as printed) |
