In the treatment program generator control table you can configure how treatment programs are generated.
1. Treatment timing - General
Allows you to control how treatment programs are generated, and how many treatment programs that are generated.
Final Felling Period Min
- Defines the minimum number of 5-year periods to postpone final felling after the corresponding lowest allowable stand age has been reached.
Final Felling Period Max
- Defines the maximum number 5-year periods to postpone final felling after the corresponding lowest allowable stand age has been reached.
Management System
- Type of management system to generate treatment programs for:
- EvenAged generates alternatives for even-aged management.
- Uneven-aged (CCF) generates alternatives for continuous cover management (also referred to as CCF, uneven-aged, selective felling, or selection harvesting).
- Unmanaged generates an alternative without any treatments.
Min Final Felling Contorta
- There is not legal minimum felling age for contorta, but the program needs a recommended one in order to generate reasonable programs.
Min Final Felling Deciduous
- The minimum final felling age is 35 years according to Swedish forestry regulations for deciduous forests (except for ash (50 yrs), beech (80 yrs) and oak (90 yrs)). However, most users wish to apply longer rotations than 35 years.
Rotation Age Adjustment
Rotation age adjustment factor. Lowest final felling age is multiplied with this factor. For example, factor 1.1 means that the miniumm rotation age allowed is increased by 10%.
Thinning Period Delay Max
- Defines the number of periods, from a certain stand age, to vary the simulation of first thinning.
2. Treatment timing - Strategic planning
Always Cleaning
- True: Only save programs that include cleanings, if cleaning is recommended according to guide.
- False: Do not save programs without cleanings, if cleaning is recommended according to guide.
Always Thinning
- True: If thinning is possible before a certain final felling period, then only programs with thinnings are saved, given that final felling period.
- False: Programs without thinnings are also saved, even if thinning is possible according to thinning guide.
Cleaning Period Delay Max
- Defines the number of periods, from a certain stand age, to vary the simulation of cleaning.
Max Number of Thinnings
- Defines the maximum number of thinnings to be simulated in a treatment unit, in the same generation.
Min Time Between Thinning and Final Felling
- Defines the minimum periods between thinning and final felling.
Min Time Between Two Thinnings
- Defines the minimum number of periods between thinnings simulated in a treatment unit.
Treatment Priority
- Defines the order, by Prio1, Prio2, and Prio3, in which treatments are to be generated in the alternative programs.
3. Treatment timing - Tactical planning
TODO
4. Fertilization
Allows you to control if and how fertilization programs are generated.
FertilizationPolicy
- Allows you to select the type of system to generate alternative programs (in treatment units where site and stand restricitions are met) according to:
- FP_NONE generates alternatives without any fertilization.
- FP_FIRSTTHIN generates alternatives with fertilization prior to first thinning.
- FP_FINALFELLING generates alternatives with fertilization prior to final felling.
- FP_FINALFELLING_TIMESTWO generates alternatives with two fertilizations, with a time interval of five years, prior to final felling.
- FP_LASTTHIN_AND_FINALFELLING generates alternatives with fertilization prior to last thinning and final felling.
- FP_EVERY_THIN generates alternatives with fertilization prior to all thinnings.
- FP_EVERY_HARVEST generates alternatives with fertilization prior to all harvests.
- FP_INTENSIVE generates alternatives with intensive fertilization, performed already in young stands and repeated with a certain time interval. Note that certain site restrictions must be met to allow for intensive fertilization.
- FP_EVERY_TEN_YEARS generates fertilization every ten years, irrespective of occurence of harvesting.
5. Forest fuel extraction
Allows you to control if and how forest fuel extraction programs are generated.
FinalFelling
- True: Extract harvest residues after final felling, False: do not.
Thinning
- True: Extract harvest residues after thinning, False: do not.
SelectionFelling
- True: Extract harvest residues after selection felling, False: do not.
