As printed (Table 3, Branch row)
Branch Wbr = 0.020D2.497
In this library's units, ready to compute (kg)
Branch biomass = 0.020 * D^2.497D- Diameter at breast height (1.3 m), cm
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).
