Summary0000437: Error when handling enforce first thinning and StemDensityThinningGuide is used
DescriptionRow 1297, class TreatmentProgramGenerator:
  enforcedFirstThinning = noOfThinnings == 0 && enforcedFirstThinning && tUnit.Before.BasalAreaExclOverstorey >= _planVisTreatmentControlTable.MinPropOfBasalAreaBefore * thinGuide.MinValueBeforeThinning;

When thinning guide is set StemDensityThinningGuide, then thinGuide.MinValueBeforeThinning refers to basal area thinning guide and is has value 0. This means the enforced thinning will approved if even stems number is very low (1 tree is enough).

Steps To ReproduceImport attached stand register, or create a spruce stand with height 12, age 22 and SIS = 30
Run PlanWise with Thinning Guide set to StemDensityThinningGuide.

Expected result: thinGuide.MinValueBeforeThinning should be > 0
Also, condition should use predicate of thinning guide, in this case stem density and not basal area.

Also note line 2451-2456: Is thinning enforced before "enforcement" criteria above are checked?

StemDensityThinningGuide now checks stem density to determine if thinning is applicable. Enforced thinnings now check this criteria before being added to a treatment specification, and before being performed.
