Tierpark Berlin is a member of the European Association of Zoos and Aquaria (EAZA) and participates in about 120 breeding programmes (EEP). It maintains the international studbooks for endangered species of deer and wild asses of Asia and Africa as well as the European studbook for little pied cormorants.[3] The zoo further participates in attempts of reintroducing species to areas where they have become endangered or extinct and it financially supports selected in situ projects for the protection of natural habitats.[4]
