In the treatment model control table you can configure how forest management treatments are simulated.
Regeneration - model
Allows you to control how forest regenerations are simulated, regarding planting, natural regeneration using seed trees, and sowing.
RegenerationModelType
- Simulation generates the new forest by simulation.
- Database generates the new forest by imputation of plot data from a database.
Regeneration - settings
DeterministicSimulation
- True applies deterministic regeneration model components, False do not.
- [Is this really applicable in Database as RegenerationModelType?]
HeightTargetRegenerationModels
- Defines the arithmetic mean height in meters at stand-level[?] when trees are initiated instead of saplings[?], for natural regeneration, sowing, spruce plantation, pine plantation, and contorta plantation, respectively.
NumberOfSeedTrees (only if Database is selected)
- Defines the number of seed trees per hectare applied in natural regeneration.
RegenerationSettings
- Defines the number of seedlings per hectare applied in plantation (or in sowing, or in natural regeneration using seed trees, respectively) following soil scarification (or controlled burning, or no preparation, respectively), regarding the site index at plot-level[?].
RegenerationYear
- Defines the number of years from time of final felling to time of regeneration applied in simulations of planting and sowing[?].
SoilPreparationYear
- Defines the number of years before regeneration when soil scarification is simulated.
Cleaning - model
Allows you to control how cleanings, a.k.a. pre-commercial thinnings, are simulated.
CleaningModelType
- HeurekaCleaning defines one model of tree removal, actually cutting of saplings, in the cleaning simulations.
- HuginCleaning defines another model of tree removal, almost as accurate as the above, in the cleaning simulations.
DeterministicCleaning
- True applies deterministic cleaning model components, False do not.
Cleaning - settings
CleaningDeciduous
- Alfa and Beta are coefficients in function calculating the priority factor of deciduous tree species. Deciduous trees, i.e. all broadleaves, will then be removed[or retained?] in cleanings prior to coniferuous trees.
CleaningPine
- Alfa and Beta are coefficients in function calculating the priority factor of pine trees. Pines, i.e. Pinus sylvestris, will then be removed[or retained?] in cleanings prior to deciduous and other coniferuous trees.
CleaningSpruce
- Alfa and Beta are coefficients in function calculating the priority factor of spruce trees. Spruces, i.e. Picea abies, will then be removed[or retained?] in cleanings prior to deciduous and other coniferuous trees.
- [How should the user select the above coefficients?]
