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.
|
| 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, where the class width = (dbhmax-dbbmin)/4. If the number of trees in class[i] > class[i+1], the diameter class distribution is classified as InverseJShaped, otherwise Homogeneous. |
