Oenocarpus ln(AGB) Hstem 4.5496 0.1387 0.784 10 0.237

In this library's units, ready to compute (kg)

Aboveground biomass = 1.0285 * exp(4.5496 + 0.1387 * Hstem)
Hstem
Palm stem height, ground to the lowest leaf, m

Exponential in stem height (Hstem, m; fitted range 2.9–14.5 m). Correction factor multiplied in.
