Cork oaks, scientifically known as Quercus suber, are evergreen trees native to the Mediterranean region. They are best known for their thick, rugged bark, which is harvested to produce cork. This unique bark can be stripped off without harming the tree, allowing it to regenerate every 9 to 12 years. These trees thrive in warm, dry climates and can live for over 200 years. Cork oaks play a vital role in their ecosystems, providing habitat for various wildlife and helping to prevent soil erosion. They are also important for the cork industry, which supplies materials for products like wine stoppers and flooring.
