Stock (forestry)

from Wikipedia, the free encyclopedia

In forestry, a stock is defined as a part of the forest that is the same in terms of shape, age and tree species or tree species mix and generally differs significantly from neighboring stands. The stand boundaries are usually used to separate subdivisions or sub-areas in forest planning ( see: Department ). The stock represents the smallest unit of silvicultural activity. In the forest enterprise, the stocks are described in the stock register according to departments. The economic planning for the next few years and the measures taken are also listed here for each stock.

If the stock is well structured, it can be divided into a dominant main stock and one or two secondary stocks in the description . The secondary stand usually includes trees that have no contact with the crown area of ​​the main stand. These trees from the lower or middle class can have a purely nurturing character or be the beginning of the new generation.

If the stand consists of only one tree species, one speaks of pure stands , with several tree species of mixed stands .

Stand layers

The stand layers form the vertical structure of the forest stand . “Within a stand layer, the trees have their canopy at the same height above the ground. Different layers of a stand have no contact with each other in the crown area. "

The layers involved in the stand structure are differentiated according to their silvicultural and economic importance:

  • Main stock: layer with the main economic weight. The stand layer is always the main stand if the coverage of the top layer is at least 5/10. Evaluations of the main stock include the plenter forest .
  • Upper stand: layer above the main stand.
  • Shelter: layer below the upper tier.
  • Secondary inventory: s. O.
