| Membership: | Treatment Unit |
| Type: | real |
| Unit/values: | (dm) |
| Database table: | (result database) dbo.Result_ForestData |
Computed as arithmetic mean height of 100 largest (diameter) trees of dominant species in a one ha stand. If there are several plots in the stand, dominant height is computed as the arithmetic average over all plots, with 100 dominant trees/per ha selected from each plot.
