AGB = 0.199(D)2.185
In this library's units, ready to compute (kg)
Aboveground biomass = 0.199 * D^2.185D- Diameter at breast height (1.3 m), cm
General (multi-site) equation fitted on pooled data compiled from published Thai plantation studies (theses, proceedings, reports), not on new felled trees; validated by the authors on independent harvests. D in cm, H in m, output kg dry weight per tree. AGB is the sum of stem, branches and leaves.

13 datasets with a total of 94 trees were chosen for E. camaldulensis
The ranges in the diameters and heights of trees in the dataset were 4.4–41.2 cm and 5.5–31.0 m for T. grandis, and 0.5–19.8 and 1.7–26.0 m for E. camaldulensis
Linear regressions of untransformed data were used in the present study because log transformed data introduced a systematic bias
