Aboveground biomass = 0.0181 * D^1.7013 * H^1.3057 + 0.0101 * D^1.5956 * H^0.919 + 0.0005 * D^2.8004 * H^0.8603 + 0.1976 * D^1.4421 * H^(-0.5264)D- Diameter at breast height (1.3 m), cm
H- Total tree height, m
Total aboveground biomass = wood + bark + branches + foliage, each fitted as its own equation; the total is their sum (additivity by construction). r2 is the adjusted R² (AdjRSq) of this compartment in Table 5. Fitted on the original scale (weighted nonlinear seemingly unrelated regression), so there is no back-transform correction. Dead branches, cones and fruits are not part of aboveground biomass in this work (Materials). Stand type was not always recorded. Ung, Bernier & Guo (2008) later revised parameters for some species with British Columbia data; not used here.

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, H = 15 | 142 | 142 | Computed from the printed form computed from the published form at dbh = 20 cm, H = 15 m |
