Schinopsis glabra / Aboveground biomass
Schinopsis glabra, caatinga, DBH
As printed (Table 2, p. 938)
In this library's units, ready to compute (kg)
Aboveground biomass = 0.2274 * D^2.271D- Diameter at breast height (1.3 m), cm
Table 2 prints each equation as a*DGL^b or a*DBH^b with the exponent as superscript (flattened here with ^). Biomass is oven-dry aboveground plant biomass in kg (Table 2 title), diameters in cm. Wood dried at 60 C. Plants were cut at the base and the stump was included in the weighed biomass. Perimeters were converted to diameters assuming a circular shape; for branching below measuring height, branch areas were summed into one equivalent diameter. DGL is stem diameter at ground level, mapped to DRC.

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 = 5 | 8.79 | 8.79 | Computed from the printed form hand-computed from the published form |
| D = 15 | 107 | 107 | Computed from the printed form hand-computed from the published form |
