A Wildbann ("wildlife ban") in the Holy Roman Empire was a specific form of royal hunting privilege.
Royal rights over any unoccupied land (ius eremi) were the legal basis for the establishment of the forestes.
As a result of the increasing importance of hunting during the 9th century, the designation of these areas changed from forestis to wildbann.
The wildbann was a hunting area under the king's ban, which extended over a region that could belong to a number of landowners.
In addition to hunting rights, the king also exercised supervision of the forest within his wildbann.
