2-2-2- Step 2: Calculating biomass volume in an individual
tree unit using allometric equations
To calculate the above-ground and below-ground biomass of a tree, we
used the well-known method developed by Ponce-Hernandez and colleagues
in 2014. The method contained several parameters of DBH, height, and
wood density (Ponce-Hernandez et al., 2004). To calculate the
above-ground biomass (trunk and crown) and below-ground biomass (root)
following sub-steps were taken:
