Aboveground Wag = 0.041D1.699H0.983 + 0.020D2.497 + 0.094D1.898
In this library's units, ready to compute (kg)
Aboveground biomass = 0.041 * D^1.699 * H^0.983 + 0.020 * D^2.497 + 0.094 * D^1.898D- Diameter at breast height (1.3 m), cm
H- Total tree height, m
Additive system fitted by WNSUR (Table 3). 131 trees (116 felled, 15 climbed standing trees); n and ranges from Table 1 and Section 2.2. Biomass of stump not included. Exponents are printed flattened in the HTML text (D followed by its exponent); read as D^exponent and consistent with Table 2. No R2 recorded (the paper gives adjusted R2 only). Stump excluded (Section 2.2).
