Magadan Oblast Branches 3.9–52.8 43 0.031 0.013 2.136 0.144 17.082; Y = a × DBH^b, Y in kg dry weight, DBH in cm

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

Branch biomass = 0.031 * D^2.136
D
Diameter at breast height (1.3 m), cm

Coefficients as printed in Table 5 (3 decimals); no log back-transform because fitted by weighted nonlinear regression.
