The Grey-headed Flying-foxes have been seasonal visitors to the Royal Botanic Gardens. At night these large bats feed on the flowers and fruits of many native plants, being important in pollinating flowers and dispersing seeds of these plant species.

However, from time to time the bats try to set up camp in the Gardens, as can be seen by looking around the Palm Grove, in the Sydney Royal Botanic Gardens. However, these bats are damaging the trees that they are roosting in, which will result in permanent damage to the trees.
 

Due to this, the Royal Botanic Gardens have been given a licence by the NSW National Parks and Wildlife Service to use non-harmful methods to discourage the bats from roosting here.
