This result group contains results that describe the Structural diversity of the trees in a treatment unit.

Variable name Unit Description
Even-aged Class code Even-aged type.
  1. Unknown: No information
  2. EvenAged: If at least 80 % of the volume are within a 20-year age range
  3. UnevenAged: Otherwise.
Note that the definition differs from the one used in the Swedish NFI.
Tree Size Diversity (Gini Coefficient) Tree size diversity (Gini coefficient).
Tree Size Diversity Class (Hugin def.) Tree size diversity class according the Hugin system definition. Trees are grouped into four diameter classes, with class width = (dbhmax-dbbmin)/4. If the number of trees in classi > classi+1, the diameter class distribution is set as InverseJShaped, otherwise as Homogeneous.
