Version 2.6.0

Summary

• Online maps (GIS plugin) included
• Buffer zones creator included in installation
• (Beta) Habitat prognosis model included as integrated component of Heureka (no need for ArcGIS license)

New functionalty

Online background maps (WMS and WMTS)

A beta version that allows you to select from a list of predefined background online maps is now included in PlanWise and RegWise. You can also define one custom connection. For SLU-users, ortofoto data can be selected from the list.

Import column in stand register breeded plants

If an existing plantation has been planted with breeded plants, you can now add a column with name "IsBreeded" to the stand register file to be imported. Set value 1 if a breeded plants have been used.

Improvements

Recreation index model modified

• The recreation model consists of three sub models, where each applies to a certain mean height interval. Now, a "smoothifying" transition zone is used between the models to minimize sudden “jumps” in the recreation index due to changed height interval. When the mean height is in the transition zone between two models, the model results are weighted.
• The recreation model considers time since last harvest operations when calculating soil damage variable. The effect of soil damages on the recreation index is assumed to decrease over time. You can change the so called Soil Damage Recovery rates in control table Recreation Model.
• The occurrence of dead wood in the recreation index model is now inactivated by default, due to the uncertainty in Heurekas dead wood model and the fact that the initial amount of dead wood inventory is seldom available in the input data.
• Intensive fertilization in RegWise was only applied on stands if to initial state was a young spruce stand with mean height between 2 and 4 m. Now site constraints are sufficient, thus allowing stands for being intensively fertilized in the next rotation.

Bug fixes and other changes

Area restrictions in RegWise

• Bug fix: Restrictions in RegWise for maximum area proportion fertilization, intensive fertilization, stump extraction, and harvest residue extraction were not implemented. The main users we have contacted say they have never needed that functionality, which is why the bug has not been discovered.
• Bug fix: No breeding effect was obtained when planting in period 0, which is now fixed.
• Bug fix: Result variable TreeSizeDiversity = UnevenAged was not implemented correctly. To be classified as UnevenAged, acccording to the original Swedish NFI definition, there must be trees in four diameter classes, and the number of trees in class i must be larger than the number of trees in class i + 1. Also, the largest tree must be at least 20 cm. The bug was that no checking was done that trees existed in the largest diameter class, which lead to that a stand could be classfied as UnevenAged, altough there were only trees in the first three classes.
• Improvement: The decision to extract fuel extraction in a stand that has been windthrown (in RegWise) is now determined by the control category settings. In previous version no biofuel was extracted after windthrow.
