Quercus suber

Quercus suber Cork oak


This evergreen Cork oak is native to the SW Mediterranean and NW Africa and flowers in April and May. It can grow to a height of 20metres. These photographs show the natural colour of the bark after it has been harvested which is done every 9-12 years. The tree has to be at least 25 years old before the bark is harvested for cork. After a fire this tree has the means to regenerate itself from every branch, as the branches are protected by a deep insulating layer of cork. Other trees after fires either die or regenerate from the base. They live for 150-250 years generally.
