The zoo’s curator, Chris Wilkinson, said the trees would make a real difference to some of the animals.
“The trees have a really nice smell that they’re not used to, so some of the animals will have a good rub against them.
“For the elephants – their habitat is full of sand, which means we can bury the trees and stand them up to make a whole forest for them to come and explore.
“They’ll eat them a bit, they’ll throw them around, they’ll explore for the food we put in.”
