How old is this tree?

We think this large Apple box tree is the oldest living tree on Flea Bog Flat. The circumference of its trunk is 3.95m which means it's probably around 300 years old. Apple Box trees have rough bark, short trunks and gnarled branches. Like many eucalypts, their juvenile leaves are quite different from their adult leaves, changing from heart-shaped grey leaves to lance-shaped green leaves.
Next to this Apple Box are a few Native cherry trees (Exocarpus cupressiformis). Native cherry trees are semi-parasitic on the roots of neighbouring trees. Their red berries which ripen in summer are an indigenous bush food.
