New Features

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
