Below ground carbon stores, comprised of above ground stump (the part that remains after a harvest), below ground stump, and coarse roots, are included within this LCA.
The amount of carbon stored within the below ground carbon stores is assumed to be the same as willow SRWCs.
No change in soil carbon down to a depth of 45 cm is expected to occur during tree growth as demonstrated by Pacaldo et al.
The system boundary ends immediately after the below ground biomass is chipped and herbicide is applied.
