Working weeks with school classes (upper level) and natural parks in the Swiss regions: the Naturkultur association has good contacts to other natural parks and regions through its dry stone wall projects, especially in Romansh and French-speaking Switzerland. In terms of an exchange between central Switzerland and schools and nature parks, the 2 resp. 3 regions set up a program in which the school classes travel to the respective other locations for a week and work on a nature mission with the local class. The learning content here is nature / cultural protection on the one hand and intercultural encounters within Switzerland on the other. In addition to the positive external effect, significant funding from foundations is also possible here.
