Mauritia ln(AGB) ln(Hstem) 2.4647 1.3777 0.897 16 0.273

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

Aboveground biomass = 1.038 * exp(2.4647 + 1.3777 * ln(Hstem))
Hstem
Palm stem height, ground to the lowest leaf, m

Height-only model: Hstem = stem height to the base of the lowest leaf (m), fitted range 5.1–30.5 m. The table row is labelled 'Mauritia'; all sampled individuals were M. flexuosa. Table 3 also gives a belowground model for this species. Correction factor multiplied in.
