Firs and spruces dominate the tree population of the Black Forest with a share of 80 percent. However, such predominantly pure stands are particularly vulnerable to extreme events caused by climate change, such as storm damage, heat waves, and bark beetle infestations. In Baden-Württemberg, on average, every third tree is already sick. A conversion from pure to mixed stands could increase the resistance of forests. The potential benefits also include greater biodiversity, long-term economic efficiency, and stability. This is the result of a study by KIT (Karlsruhe Institute of Technology) for which experts from forestry, silviculture, and tourism were interviewed.
