As printed (Table 5)

Magadan Oblast Foliage 3.9–52.8 43 0.016 0.006 1.835 0.130 2.601; Y = a × DBH^b, Y in kg dry weight, DBH in cm

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

Foliage biomass = 0.016 * D^1.835
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.
