Cork Oak Forest at the National Arboretum Canberra turned 100 years in November 2017.
It's an amazing tree. This is one of the few trees able to regenerate their bark. Cork is a kind of bark where the dead cells are waterproofed by a wax called suberin. Most trees produce some cork but the cork oak produces lots! Some scholars argue that the existence of cork oaks dates back over 60 million years. It has been scientifically proven that cork oaks survived the ice age in the Mediterranean Basin, over 25 million years ago. In Portugal, where the largest cork oak forest area in the world is found, a fossil fragment over ten million years old was discovered which is testament to the ancient existence of this tree in the country.
