0000815: Add the field IsThinned to stand register

Fri, 29 May 2026 08:52:53 +0200

Currently a user can add the date for the last thinning in the field LastThinningDate. However, if a thinning has NOT been made the user can't stop the system from assuming a thinning HAS been made. See GetNumberOfThinnings(...) in ThinningGuidebase.cs

Add a new field like "Thinned"/"IsThinned" to the stand register. Do not forget to update the Excel template and the wiki.

If LastThinningData is set: the field IsThinned can/should be ignored and LastThinningData should be used.
If LastThinningDate is missing and IsThinned is false or missing: Heureka should not infer that there is been thinnings.
If LastThinningDate is missing and IsThinned is true: Heureka will assume 1 thinning has been made

0000816: Fix inference of historical thinnings

Thu, 28 May 2026 13:34:07 +0200

Now the algoritm for infering if thinnings has been done but are missing from for example LastThinningData in the stand register uses the current period. That means the number of infered periods can change over time. It would make sense to only evaluate the forest state in period 0 and then use that result.

First time attempting the import of treatment proposals. Below is the CSV string that is throwing an error. Advice would be appreciated!

AreaLevel2;AreaLevel3;StandId;Treatment;Year;Species;ThinningForm;ThinningGrade;
1;1;ExampleSpruce1;4;2053;G;1;0.33;
1;1;ExampleSpruce1;8;2063;G;1;1.00;

AreaLevel1,2, and Stand ID match the StandData sheet.

0000817: Missing thinnings with period midpoint

Fri, 15 May 2026 14:54:11 +0200

If the dominant height is too high for a young stand first thinning and no thinning was found and a thinning should be enforced, the wrong thinning period is calculated if period midpoint is used and the thinning can not be applied

0000798: Report Template selections are reset between sessions

Wed, 06 May 2026 10:33:28 +0200

Selections should remain between sessions and be specific to the project.
Should be implemented similarly to how result variables are handled.

0000807: The result variables for growth data are not correct for Checkboard management

Wed, 06 May 2026 10:32:26 +0200

The result variables for growth data (CAI) are miscalculated due to the assumption that one year can not have multiple harvests.

0000808: Incorrect version handling of final felling and thinning delay values

Wed, 06 May 2026 10:31:38 +0200

Final felling and thinning delay control table variables' units were changed from period to years.
However, the conversion of values between version were done incorrectly, making some values not convert correctly.
All values should now convert correctly from period to years.

0000814: Optimization results in column mode not updating

Fri, 24 Apr 2026 12:36:22 +0200

When looking at optimization results in column mode the view is not updated when number of periods is changed in the numericupdown.

Hello Jonatan,

when i am trying to load all treatment units from a simulation using Regwise i am getting this error message. "Damage risk data potential basal area already belongs to this data table". the treatment units is not loading and i am not able to click on "select variables". but i can see simulation output from single treatment unit and i can select the output variables for one treatment unit. any idea on what is causing this problem?

--- Exception ---
System.Data.DuplicateNameException: A column named 'DamageRiskData Root Rot Potential Basal Area' already belongs to this DataTable.

0000812: Change: Removed Cudafy from HabitatModel

Fri, 20 Feb 2026 13:40:15 +0100

The outdated package Cudafy was used when evaluating Habitat models. The package is now removed. It should not have any side effects.

0000806: Wrong coefficients in tree age functions

0000805: Blir ingen gallring när Thinning Delay Max sätts till 0

Fri, 19 Dec 2025 16:10:13 +0100

För beståndet sker gallring i period 2 och 3 och slutavverkning i period 6 om Thinning Period Delay Max = 2.
Om Thinning Period Delay Max sätt till 1 blir det gallring i period 2.
Om Thinning Period Delay Max sätts till 0 blir den ingen gallring alls.

0000801: Önskad funktionalitet. TIllåt specifika trädslag i UserDefined-result

Tue, 25 Nov 2025 09:12:25 +0100

Jag vill kunna redovisa volym RASE (Rönn, asp, sälg, ek). Ek och asp finns som egna trädslagsgrupper, men sälg och ränn ingår i OtherBroadleaveas.
En lösning vore att tillåta att ett User Result definierar för specifikt trädslag (Species) och inte bara trädslagsgrupp. Undrar om inte denna funktionalitet har funnits tidigare?

0000531: Feature request: let user define LastThinningYear as none

Tue, 25 Nov 2025 09:03:02 +0100

Hej!
Hur kan man ange i beståndregistret att ett bestånd är ogallrat? Om LastThinningYear saknas tolkar programmet det som att gallringshistorik saknas, men om man uttryckligen vill ange att beståndet är ogallrat, hur gör man då?

Mvh Peder

0000799: TPG missar gallringar?

Thu, 20 Nov 2025 15:37:27 +0100

Bifogar exempel där det borde gallras i period 1 när man kör med periodmitt, men av okänd anledning görs det inte.
Grundytan är hög och enligt bakomliggade gallringsmall (SKS) borde det vara hög gallringsprioritet.
Relativa åldern är inte för hög och inte heller övre höjd (dominant height).

0000796: The order of map layers makes a difference when calculating intersections in the Initial State --> Map view

Wed, 12 Nov 2025 10:43:11 +0100

To get the correct behavior, the 'Stands' node needs to be down furthest down the Map Layers list.
However, there are a lot of problems with the map currently, better solve them in a more stable .NET8 Heureka release since other libraries are used there.

0000781: StandWise 2D and 3D maps are not consistantly updating correctly to changes

Wed, 12 Nov 2025 10:26:20 +0100

If the tabs are not in focus, sometimes the events don't fire correctly, causing the visual data to be out of sync.

0000797: Thinning Delay is given in periods but would be better if it could be specified in years

Wed, 12 Nov 2025 10:24:47 +0100

It would be more accurate if it could be given in years. This change has already been done for Felling Felling Delay, so this change should be similar.

0000784: Adding "/" to report name when copying a report throws unhandled exception

Wed, 12 Nov 2025 10:24:29 +0100

We should add or improve input validation for filenames of reports.

0000787: Incorrect view of optimization results for simulations with same names

Wed, 12 Nov 2025 10:24:17 +0100

If the same result database is used in multiple projects and simulations have the same name, the optimization results are displayed under the "wrong" simulation when "display simulations/optimizations from any project" is checked (General Settings).
