ControlTable Scenario Settings

User's guide to RegWise

This control table is specific and essential for RegWise. It contains settings for determining harvest levels in scenarios and priority functions for allocating activities to treatment units. Regional Framework is used instead of Treatment Program Generator in PlanWise - while the Treatment Program Generator generates a variety of alternative treatment programs to each treatment unit (to enable optimization) the Regional Frameworks purpose is to "pinpoint" one specific treatment program for each treatment unit. This separates simulation from optimization. Do observe that the pinpointing sometimes involves randomization, meaning that the user then leave some decisions to chance.

Program Restrictions

Management System

Select the management system to be applied: Even-aged, Uneven-aged (CCF), or Unmanaged.

Priority Function Periods

Select the number of five-year periods where the NFI priority functions are to be used.

Random Seed

Treatments are basically assigned in priority order. It is possible to let the system enforce deviation from this order by, with a certain probability, skipping a treatment for a treatment unit and go to the next unit in the priority list. The reason for doing this is to account for non-predictable behaviour, since not all forest owners are following the "management handbook". This means that two identical scenarios (i.e. identical assumptions and input data) will give different results, which sometimes makes conclusions difficult to draw. Setting the random seed to a number larger than 0 will give the same result for two identical scenarios.

Priority Order For Different Treatments

Select the order for which priority functions should be run and treatment generated. This may have a minor importance. Choosing Thinning before Final Felling means that a stand with a high priority for both thinning and final felling, will be considered for thinning as a first option.

Harvest Levels

Total Harvest Level, Automatic

Here you can edit the function, based on growth etc., calculating the total production.

Reference Production

Here you can edit the function calculating the reference production, used in the above.

Final Felling Volume Per Year

Here you can give a certain "target volume" regarding final felling, in certain periods.

Thinning Volume Per Year

Here you can give a certain "target volume" regarding thinning, in certain periods.

Thinning Volume Proportion, Automatic

Here you can edit the function calculating the proportion of the total harvested volume following from thinning.

Max Proportion Thinning

Here you can give the maximum proportion of the total harvested volume following from thinning.

Thinning Distribution

Here you can edit the accumulated probability of thinning, regarding the relative age.

Selection Felling Volume Per Year

Here you can give a certain "target volume" regarding selection felling, in certain periods.

Priority functions

Jump In Priority Order

Here you can skip every n:th treatment unit to be prioritized for thinning and final felling.

Priority Function Cleaning

Here you can edit the function prioritizing cleaning.

Priority Function Thinning

Here you can edit the function prioritizing thinning.

Priority Function Final Felling

Here you can select the function prioritizing final felling.

Priority Function Fertilization

Here you can edit the function prioritizing fertilization.

Thinning

In this section, additional settings for thinnings can be made (not available in ControlTable Treatment Model but unique for RegWise)

Forest fuel

In this section, you can set whether forest fuels (harvest residues) should be extracted after harvesting.
