Eucalyptus camaldulensis / Stem biomass
Eucalyptus camaldulensis stem (wood + bark) biomass from D²H

In this library's units, ready to compute (kg)
Stem biomass = 0.019 * (D^2*H)^1.005D- Diameter at breast height (1.3 m), cm
H- Total tree height, m
General (multi-site) equation fitted on pooled data compiled from published Thai plantation studies (theses, proceedings, reports), not on new felled trees; validated by the authors on independent harvests. D in cm, H in m, output kg dry weight per tree. AGB is the sum of stem, branches and leaves. Component symbol in the paper: Ws. The paper labels Wb as bark in its tables but as branches in the text, so no branch or bark model is entered.

13 datasets with a total of 94 trees were chosen for E. camaldulensis
The ranges in the diameters and heights of trees in the dataset were 4.4–41.2 cm and 5.5–31.0 m for T. grandis, and 0.5–19.8 and 1.7–26.0 m for E. camaldulensis
Linear regressions of untransformed data were used in the present study because log transformed data introduced a systematic bias

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, H = 10 | 12.6 | 12.6 | Computed from the printed form computed from the published form |
| D = 15, H = 18 | 80.2 | 80.2 | Computed from the printed form computed from the published form |
