The Hanover Zoo encloses a territory of 22 acres. In 2020, the location shelters about 2150 animals of 181 species. The conventional presentation of animals in a zoo had been abandoned in favour of preferring semi-natural habitats since the end of the 20th century with a view to approaching EXPO 2000 in Hanover. Thereby seven topic areas emerged, based on the genuine habitat and the cultural environment from where these animals originate. Visitors can encounter the presented animals grateless but these are just as well able to withdraw into peacable parts of their enclosures.
