Water maintenance

Watercourses are important linear structural elements in the forest as they connect different habitats. The municipal forestry office pays particular attention to ensuring that the natural stream bed is preserved. We also maintain and promote the development of natural stream flora. Some watercourses have already been "cleared"; the resulting open spaces are either left to natural succession or extensively planted with native tree species (e.g. alder, ash, willow).

The continuity of watercourses and passability for aquatic organisms is also an important concern for us. Ecologically compatible, but also cost-intensive water crossings are bridges, as sufficient light enters and the natural river bed is preserved. However, piping as watercourse crossings under forest roads is the rule. Particular attention is paid to the choice of pipe diameter, profile, length and inclination, especially when constructing new pipes or carrying out repair work. These parameters ultimately influence the flow velocity, sediment transport and light incidence and determine whether the pipe represents an obstacle to migration or not.
