Equations / Stem biomass
Avicennia lanata Stem biomass from DBH (Table 1)
As printed (Section 3.1, p. 401)
In this library's units, ready to compute (kg)
Stem biomass = 0.1143 * D^2.3429D- Diameter at breast height (1.3 m), cm
Form Y = g X^h, no correction factor stated. The paper does not state units in the text; DBH in cm and biomass in kg are read from Table 2 and the axis labels of Figures 2 and 3. The DBH range of the 13 harvested trees is not stated (Table 2 describes the stand), so no range is given. Young natural regeneration: the stand census in Table 2 ran from 2.7 to 9.4 cm DBH and the stand was under 10 m tall (Section 2.1).

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 = 3 | 1.5 | 1.5 | Computed from the printed form computed from the published form Y = g X^h |
| D = 6 | 7.61 | 7.61 | Computed from the printed form computed from the published form Y = g X^h |
| D = 9 | 19.7 | 19.7 | Computed from the printed form computed from the published form Y = g X^h |
