In an attemt to learn more about common trees planted in enclosures of zoo animals in zoos World-Wide, or planted outside enclosures throughout the zoo, I created this thread. I will choose mine 5 favourite zoo trees. It's best for such trees to be non-toxic, to be used as browse for browse-eating animals, and to be attractive and provide good climbing opportunities and shelter for protection from sun. Here would be mine: Arbutus andrachne (human skin-colour of it's stem, branches), evergreen Ficus elastica Wild olive tree Tilia spp. trees Willow tree (particularily high amount of leaves, as like food for giraffes - or particularly for black rhino). (Eucalyptus (several species) mandatory for Koalas )
