Fagus sylvatica / Aboveground biomass
European beech AGB, RIM, Dataset #3, D only
© Rebecca Gimenez Husted · CC BY · iNaturalistAs printed (Table 5, European beech, RIM, Dataset #3, ln(D) (Equation 2; back-transformed as Equation 4))
In this library's units, ready to compute (kg)
Aboveground biomass = 1.0148 * exp(-2.1312 + 2.4714 * ln(D))D- Diameter at breast height (1.3 m), cm
Fit on Dataset #3 (generic + full site sample). Whole-tree dry AGB including foliage (stem and branches with leaves/needles weighed and dried). Equation form AGB = exp(β0)·D^β1·(H^β2)·CF with CF = exp(σ²/2) printed in Table 5 and applied here. D in cm, H in m, output kg (units not restated beside Table 5; stated in Table 1 for D, H, AGB). For RIM models the parameters printed are those retained for the Șinca site.

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 | 198 | 198 | Computed from the printed form computed from the published form (coefficients as printed) |
| D = 50 | 1,904 | 1,904 | Computed from the printed form computed from the published form (coefficients as printed) |
