Natural age range
As natural ages in are silviculture stages of development in managed forests designated. The division is primarily based on the prevailing tree size, which is determined by the height or the breast height diameter (BHD). It is therefore only possible in herds of more or less age. Regionally, the names of the individual levels and, above all, the boundaries between the levels can vary slightly to significantly.
| Natural age range | feature |
|---|---|
| Young stature | a naturally or artificially established young stand until the stand closes (state in which the crowns of a stand are in mutual contact) or up to a height of 2 m |
| Young population | from the end of the inventory until a BHD of 15 cm is reached (see also thickening ) |
| Pole wood | mainly trees with a BHD 7–20 cm |
| Tree wood | BHD> 20 cm, can be further subdivided into

- The stages of development according to the Swiss national forest inventory are defined as follows: young growth / thickening D dom <12 cm; Pole D dom 12–30 cm; weak tree wood D dom 31–40 cm; medium tree wood D dom 41–50 cm; thick tree wood D dom > 50 cm, where D dom denotes the mean diameter of the 100 thickest trees per hectare.
