New Features

Lämna andel av gallrade träd i skogen som död ved

Användaren ges möjlighet att låta träd ligga kvar i skogen efter gallring, till exempel efter en gallring i naturvårdande syfte. Anges som en andel av totala antalet gallrade stammar som ska ligga kvar som liggande död ved efter gallringen. (Default 0%)

Nya resultatvariabler för död ved 20 cm eller grövre

Nya resultatvariabler finns tillgängliga för att visa hur mycket död ved med en diameter över 20 cm som finns av den totala mängden död ved. Initialvolymen för andelen död ved över 20 cm (av total mängd död ved) utgår utifrån data från Riksskogstaxeringen: 50 % i Norra Norrland, 60 % i resten av landet, och 70 % i naturreservat (hela landet).

Markkol i torvmark

Nu simuleras hur markkolförrådet i torvmarker förändras med hjälp av emissionsfaktorer. På dikad torvmark minskar markkolförrådet över tid, medan det antas vara konstant i odikade torvmarker.

Initialvärdet för markkol i torvmark är baserat på markkolsinventering. Tidigare simulerades markkol i torvmark med Q-modellen, vilket kunde ge felaktiga resultat eftersom Q-modellen bara är lämplig för mineraljord.

Bug Fixes

Project imported data set to new start date (Beta)

Heureka now has a function (Beta version) for projecting the state of an imported data set, from the inventory date specified for each stand, to a desired start date for a new analysis. The program then creates a new area and the old data is not affected. In the projection, the program asks if you want to include treatments that have been carried out since the inventory. See the help documentation for more information: English Swedish

Conditional control tables - direct linking of control tables to stands

"Conditional control tables" is a way to link specific control tables to stands, and takes precedence over the links created via forest domains and control categories. The feature is particularly useful if you have many different geographical regions in an analysis area, for example price regions, and can help keep the number of forest domains and control categories down to a minimum. See the help documentation for more information: English Swedish

New result variable for total dead wood volume

To get total dead wood volume, you must sum volumes over decay classes manually, which prevents making graphs and tables that shows the total volume of dead wood. Therefore, a new result variable called "Volume Deadwood All Decay Classes to Include" has been added. You can select what decay classes that should be included in this variable in the Dead Wood control table. For example, you may prefer to exclude the classes with almost completely decayed wood. All decay classes are included by default.

PlanWise: Let non-fertilization alternatives be generated automatically

A new setting in the Treatment Program Generator control table called "Also Generate Programs without Fertilization" simplifies things if you want create treatment programs both with and without fertilization. If the parameter is set to true, you do not need to add a separate control category to generate non-fertilized alternatives, they will be generated anyway.
You can read more about this new feature here: Fertilization in PlanWise

Explicit dates saved

In previous versions only the inventory year has been saved in the database when importing data, but now on the explicit date is kept (if available). The column name "InventoryYear" in the stand register is renamed to "Date" (although "InventoryYear" can still be used as column name).

Multiple TPG-simulation can be included in the same optimization model

When solving an optimization problem, multiple TPG-simulation results can now be selected as input data. A condition is that no two TPG-simulations contains the same treatment unit, and an error message will be displayed of that criteria is violated.
