The tree hollows in Scribbly Gums are very important in the forest ecosystem.
They provide nesting hollows for the Powerful Owl who is the apex predator on the peninsula and an endangered species due to forest clearing.
They catch and feed on many of the 22 mammals found in the area. These include the possums, bats, bush rats and antechinus. Even birds such as Kookaburras and Tawny Frogmouths.
During the day when not nesting the owls will hide in the thick cover of trees such as the Black Sheoak. They are nocturnal hunters.
The hollows have to be at least 0.5 m deep and it takes about 150 years for these to develop in the Scribbly Gum.
The owls mate for life and the larger male will roost nearby in another hollow to guard the nest and bring food.
Sites where there is dense tree cover between the tree hollows are preferred as other birds constantly try to attack them and drive them away.
