New Features

Adjustment Factors per Species and Period

The settings Growth Factor and Mortality Factor Established Forest have been moved into a new control table setting called Growth and Mortality Adjustment Factors. A factor for height growth has also been added.

The new setting comes with an editor that allow for setting these Factors per period and species.

Shrub Cover Models

Three new result variables have been added: Bilberry-, Heather- and Cowberry-cover. These can be found in the result category Non-wood ecosystem services.

There are two available models for calculating Bilberry- and Cowberry-cover. These can be changed in the control table Recreation.

Please note that the Hedwall models can only be used with a database containing data for inventoried cover for respective species and the carbon:nitrogen-ratio in the humus layer.

Environmental Goal Indicators

Four new result variables have been added to the result category Structural Diversity, with conditions to be classified as such as follows:

• Deadwood-rich forest: 20 cubic metres of dead wood with a diameter of at least 20 cm.
• Forest with 60+ large tree: At least 60 large trees per hectare. At least 45 cm in diameter for conifers, beech and oak. At least 35 cm in diameter for other species.
• Mature broadleaf-rich forest: Forest that older than 80 years in boreal regions or 60 years in boreonemoral and nemoral regions, and at least 25 % of the basal area is broadleaf.
• Old forest: Forest older than 140 years in boreal regions or 120 years in Boreonemoral and nemoral regions.

There is a premade report called Miljöförhållanden for displaying the environmental goal indicators. Download it by clicking the Download Templates-button. It can then be found in category 6. Naturvård.

Other Changes

• Updated application suite to .NET Framework 4.8
• Changed name of control table Soil Model to Carbon
• Changed name of result group Recreation to Non-wood ecosystem services, including also the shrub cover model results
• Changed name of result group Harvested Wood Products to Carbon in Harvested Wood Products
• Added settings for Harvested Wood Products to the Carbon control table
• Time between thinning and final felling is now specified in years instead of periods, in the Treatment Program Generator control table
• Faster loading of map control in initial state
• Simplified import format for optimization results (the old format is still supported)
• Birch added as its own category in the Dead Wood result group
• User can now specify a fraction of cut stems to leave in forest as dead wood after a final felling treatment in the Treatment Model control table

Bug Fixes

• RotationAgeFactor was not considered when calculating initial state
• Register Tree Data had a faulty plot type check
• Possible incorrect wait time between thinnings and other treatments in tactical TPG
• Tree List Importer didn't show an error when the mandatory column InventoryYear was missing
• Mortality was sometimes over- or underestimated in RegWise
• Wrong decay class assigned to dead trees in IPAK importer
• NPV incorrectly calculated in the optimization summary (not in the actual results)
• StandWise: Overstorey trees that were previously removed would return when backing to period 0, and never be removed again
• Fixed error when cleaning period overlapped final felling period in TPG
• Fixed error when importing optimization model item
• Fixed crash when calculating cliques and clusters
• Forwarder cost could be calculated to a negative value in very harsh conditions
• After treatment proposals were applied, the control category for the first generation was always used even if a final felling was performed
