ControlTable Production Model
In the production model control table you can configure the simulation of the forests' development, i.e. how trees establish, grow, and finally die if not harvested before that.
Growth and yield
Allows you to control the net growth and yield from harvests, by applying certain models/-components in the simulations.
CalculateStandGrowthForLargeTreesOnly
- True implies that stand growth is calculated as the growth of trees with at least 10 cm's diameter only, False do not (i.e. includes all trees' growth).
CalibrateHeight
- True implies that tree heights will be calibrated, False do not. Calibration factors are calculated using sample tree data.
HeightGrowthModel
- ErikssonElfving implies that the model by Eriksson and Elving will be used in calculation of height development.
- SoderbergWithTreeAge implies that the model by Söderberg including single tree ages will be used in calculation of height development.
- SoderbergWithStandAge implies that the model by Söderberg including average stand ages will be used in calculation of height development.
HeightTresholdPlantToTreePlot
- Defines the average tree height at stand-level[?], in meters, when saplings are turned-over and classified as trees.
InitialHeightModel
- SoderbergWithTreeAge implies that the model by Söderberg including single tree ages will be used in calculation of initial tree heights.
- SoderbergWithStandAge implies that the model by Söderberg including average stand ages will be used in calculation of initial tree heights.
InitialHeightSource
- UseFunction implies that the model selected in InitialHeightModel (above) will be used.
- FromDatabase implies that initial tree heights will be obtained from an available database [The Hugin young forest-database?].
MortalityFridmanOnly
- True implies that the model by Fridman and Ståhl will be used in calculation of mortality, False implies that the model by Söderberg and Bengtsson will be used together with the model by Fridman and Ståhl.
MortalityModel
- Deterministic will apply deterministic components in the mortality model.
- Stochastic will apply stochastic components in the mortality model.
- None will not apply any mortality model.
