Equation

As printed (Table 2, p. 12)

0.00204d2h

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

Branch biomass = 0.00204 * D^2 * H
D
Diameter at breast height (1.3 m), cm
H
Total tree height, m

Equation as printed in the Table 2 system for this taxon; d is DBH in cm, h total height in m, output in kg dry mass. R² is the 10-fold cross-validation value. Printed "J. depeanna" in the paper; the accepted spelling is Juniperus deppeana.
