The primary objective in national parks is to let nature be nature. National parks are landscapes in which nature is left to its own devices and its own laws. They create or preserve refuges for wild plants and animals and are therefore indispensable for the biological diversity and species richness of our earth.

Therefore, the main task of the Harz National Park is to preserve and protect the natural diversity and dynamics of the habitats and the animal and plant species that live there. In many areas of the national park, nature is therefore allowed to develop free from human influence
