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

Aboveground biomass = 0.773 * H^4.347
H
Total tree height, m

HMax is the maximum canopy height of the tree, taken as total height H. Trees in the study were 0.62 to 5.83 m (Table 1, all 20 measured trees, so not given as a fit range). The canopy-area equations in Table 2 have no canonical input and are not included.
