Definition of permanent forest

In the naturally managed forest, in the permanent forest, no extensive cuts are carried out. The mature trees are used individually. This leads to an uneven structure, which maintains or increases soil fertility, ensures automatic forest renewal, and optimises the permanent high-quality use of wood and operational safety. This ensures a high level of economic efficiency. In addition, a multifunctional, socially acceptable forest is created.

Unlike the Plenter forest, the permanent forest is not defined by its structure, but by the silvicultural will of the forest owner or manager.

Holistic preservation and care of the local forest ecosystem

• Consideration of relief, soil, microclimate, forest community, fauna and flora
• Application of a silviculture technique that includes harvesting timber, the promotion of young talent and the selective education of tree individuals in the same operation
• Care and promotion of the individual tree and thus optimum exploitation of the individual performance potential of each tree
• Harvesting the elite trees shortly before they reach their highest economic value
• Use on the entire forested area of the farm individually or in groups at intervals of 3 to 8 years without bordering.
• Rejuvenation under umbrella in the light wells that are created during use; no labour-intensive interventions in forest management
• Exploitation of the natural selection and differentiation process
• Promotion of the texture, i.e. the distribution and mixing of old and young, thick and thin trees.
• Striving for high vitality and, as a result, sustained high mechanical and biological stability of the individual tree through optimisation between the trunk of valuable timber and the green crown.
