Fagus moesiaca / Stem biomass
Fagus moesiaca stem dry biomass within the crown, DBH (Table III lnMCS)
© Igor Balashov · CC BY · iNaturalistAs printed (Table III, model in caption and lnMCS row, p. 442)
In this library's units, ready to compute (kg)
Stem biomass = 1.1914 * exp(-4.0543 + 2.2116 * ln(D))D- Diameter at breast height (1.3 m), cm
D is DBH at 1.3 m. Multiply by Table III's CF once; it equals exp(SEE²/2), although the text calls SEE²/2 CF. Stem mass within the crown only, not whole-stem biomass. The retained 5.19–40.6 cm range is explicitly reported in the methods (p. 441); the later comparison describes a largest Greek tree of 41.45 cm (p. 446). That sample-description discrepancy is not used to extend the reported range.

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 |
