Operating mode (silviculture)
As modes are in the forestry - usually on stock level different - wood structural engineering refers to concepts and forestry systems. They differ in the type of stand establishment , the way in which the wood is harvested , the spatial and temporal sequence of the harvest and the resulting differences in forest structure and wood harvest products.
There are 3 main operating modes:
- High forest ( core growth farm )
- Niederwald ( extraction company )
- Middle forest (combination of high and coppice forest)
Some key differentiators:
| Operating mode | High forest | Mittelwald | Niederwald |
|---|---|---|---|
| Type of taper | Natural regeneration , sowing, planting | Natural regeneration, planting, stick rash | Stick rash, root spawn |
| Choice of tree species | suitable for all tree species | limited, as it is restricted to species with a stick capacity and root spawn | limited, as it is restricted to species with a stick capacity and root spawn |
| Taper shape | Femelschlag , Saumschlag , Umbrella , clear-cut , combined forms | Umbrella strike | Clear cutting |
| Production target | Valuable wood | Valuable timber ( construction timber ) and firewood | firewood |
