Equation
As printed (Table 5)
Magadan Oblast Aboveground 3.9–52.8 43 0.097 0.019 2.423 0.062 45.071; Y = a × DBH^b, Y in kg dry weight, DBH in cm
In this library's units, ready to compute (kg)
Aboveground biomass = 0.097 * D^2.423D- 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.
