Sherry Oak is a type of oak tree primarily found in the Mediterranean region. Known scientifically as Quercus suber, it is famous for its thick, corky bark, which is harvested to produce cork. This tree can grow up to 20 meters tall and is well-adapted to dry climates, making it an important species for both ecology and economy. The bark of the Sherry Oak is harvested every nine years without harming the tree, allowing it to continue growing. This sustainable practice supports local economies and provides materials for various products, including wine stoppers and insulation. The tree also plays a vital role in its ecosystem, providing habitat for various wildlife species.
