“Let nature be nature” is the philosophy of the Bavarian Forest National Park. Despite massive resistance, this vision has become a groundbreaking showcase project. Because humans do not interfere with nature, the former commercial forests grow into a primeval forest, a unique ecosystem and a refuge for biodiversity. People from all over the world come here. They are looking for answers to the question of why we need more wild nature and what we can learn from it to preserve forests for future generations in times of climate change.
