Map notes
During the ‘On remediation and interfacing’ education programme, students visited the Fungus Herbarium of the State Museum of Natural History Karlsruhe and searched for mushrooms in the Rappenwörth forest. Although it is impossible to map the exact locations of mushroom growth, it is possible to identify areas with a high likelihood of occurrence. This map combines three such indicators: observed soil organic carbon levels between 9 and 12, soil acidity (measured in H₂O) between pH 5.5 and 6.5, and high available water capacity in the topsoil. Darker shading indicates more favourable conditions.
