Fagus moesiaca / Stem biomass
Fagus moesiaca stem dry biomass, nonlinear DBH fit (Table IV Ms)
© Igor Balashov · CC BY · iNaturalistAs printed (Table IV, model in caption and Ms row, p. 443)
In this library's units, ready to compute (kg)
Stem biomass = 0.7568 * D^1.9536D- Diameter at breast height (1.3 m), cm
D is DBH at 1.3 m. This original-scale nonlinear fit needs no log back-transformation correction. The authors report better SSE for nonlinear models, but lower MPD for the log models of total, stem and branch mass. 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%.
