This result group contains: Volume of dead wood per decay class.
Calculation of dead wood
See model description for model description for dead wood.
The projected occurrence of dead wood is a result of dead wood inventory data (if supplied or calculated), occurrence of mortality, and dead wood decay.
Note! All dead wood results refer to the stem part, including bark, above ground. Branches, foliage, tree tops, stumps and roots are input to the soil carbon model, if not extracted as biofuels. Only mortality in established stands is transferred to the dead wood pool, mortality in young stands are transferred as litter to the soil carbon model.
Result variables
MinDiameter, indicates if the minimum diameter set in the Dead Wood control table (default 10 cm) is used.
| Variable name | Unit | Min diameter used? | Description | |
| Carbon in Deadwood | tonnes C/ha | Yes | Carbon content in dead wood, based on the biomass (which differs between decay class) in stem and bark. | |
| Dead Standing Trees | volume, m3sk/ha | Yes | Volume of dead standing trees, with a diameter ≥ MinDiameter when the tree died. Depending on decay class, a certain proportion of the dead wood is assumed standing dead trees, and the rest assumed downed, see table below. | |
| Dead Standing Coniferous Trees | volume, m3sk/ha | Yes | Volume of dead standing trees of pine, spruce, and Logepole pine. Larch is also included. | |
| Dead Standing Deciduous Trees | volume, m3sk/ha | Yes | Volume of dead standing trees of broad-leaved trees. | |
| Downed Dead Wood | volume, m3sk/ha | Yes | Volume of downed standing trees, with a diameter ≥ MinDiameter when the tree died. Depending on decay class, a certain proportion of the dead wood is assumed standing dead trees, and the rest assumed downed, see table below. | |
| Downed Standing Wood Coniferous | volume, m3sk/ha | Yes | Volume of downed dead wood of pine, spruce and Logepole pine. Larch is also included. | |
| Downed Dead Wood Deciduous | volume, m3sk/ha | Yes | Volume of downed dead wood of of broad-leaved trees. | |
| Volume Decay Class 0-4 | volume, m3sk/ha | No | Volume of dead wood in a given decacy class. |
