Native Animals Dependent on Hollow Bearing Trees

Did you know that there are many native animals in Pittwater which are dependent on tree hollows for bearing and rearing their young? Animals such as sugar gliders, owls, parrots, cockatoos and some micro bats rely on hollow-bearing trees for their survival and viability.
Loss of wildlife corridors and hollow-bearing trees means that these animals have few places to breed and bear their young, and are forced to come to ground where they are vulnerable to diseases such as Toxoplasmosis and predators such as domestic cats.
What can you do?
- Plant and retain native habitat in your garden, especially hollow-bearing trees. Talk to Council's Bushcare Officer on 9970 1363 to find out the best trees to plant in your area.
- If trees with hollows have to be cut down, keep the hollow branches and stumps in your garden so that animals can use them for habitat.
- Install a nest box in your garden.
- If unsure, seek advice from Council's Bushcare Officer on 9970 1363 or contact a bush regeneration contractor.
