In the dead wood control table you can configure the simulations of dead wood development, from the time of a single trees' death to complete decomposition.
Dead Wood
Allows you to control how the decomposition, and if any extraction of dead wood (sometimes used as forest fuel), should be simulated.
Decomposition Rate Biomass
- Aspen defines the rate of decomposition, in percentage per year, of biomass of Populus tremula.
- Beech defines the rate of decomposition, in percentage per year, of biomass of Fagus silvatica.
- Birch defines the rate of decomposition, in percentage per year, of biomass of Betula ssp.
- Broadleaf defines the rate of decomposition, in percentage per year, of biomass of broadleaves other than birch and aspen (sv: triviallöv).
- Contorta defines the rate of decomposition, in percentage per year, of biomass of Pinus contorta.
- Deciduous defines the rate of decomposition, in percentage per year, of biomass of broadleaves other than beech and oak (sv: ädellöv).

Min Density
Intial dead Wood
Initial Dead Wood
Source for initial dead wood:
- Database
- Initial dead wood will be primarily read from inventoried dead wood, secondarily standregister is read for data on dead wood.
- Simulation
- Initial dead wood is simulated at according to setting for simulation level.
- None
- No nitial dead wood will be considered, even if inventory data for dead wood is avaliable.
Simulation Level
Amount of initial dead wood to simulate if Initial Dead Wood = Simulation.
Low = 2.15 m3/ha,
Medium = 4.3 m3/ha,
High = 8.6 m3/ha
Last Decay Class Inventoried
If for example only decay classes 0-2 has been inventoried, set to 2 = Slightly decomposed. This will have the effect that if the decay class has not been registered for a dead tree, the dead wood volume of the tree will only be distributed to the classes inventoried, see Dead wood decay class distribution
Dead wood decompostion due to final felling
Enable decomposition due to final felling
If set to True, increased decomposition of dead wood in the clear cut stand and in retention patches that belong to the stand, can be simulated. When set to True, parameters "Decomp. ..." below are displayed.
Decomp. Final Felling No Soil Preparation
Amount of additional decomposition of dead wood when final felling is performed on clear cut areas without soil preparation
Decomp. Final Felling Soil Preparation
Amount of additional decomposition of dead wood when final felling is performed on clear cut areas with soil preparation
Decomp. Set-Asides No Soil Preparation
Amount of additional decomposition of dead wood when final felling is performed on set-aside areas without soil preparation
Decomp. Set-Asides Soil Preparation
Amount of additional decomposition of dead wood when final felling is performed on set-aside areas with soil preparation
