Quercus suber, commonly known as the cork oak, is a species of oak tree native to the Mediterranean region. It is best known for its thick, rugged bark, which is harvested to produce cork. This tree can grow up to 20 meters tall and typically thrives in warm, dry climates. The cork oak is a vital part of its ecosystem, providing habitat for various wildlife. It is also economically important, as cork is used in products like wine stoppers, flooring, and insulation. The tree can live for over 200 years and can be harvested for cork every 9 to 12 years without harming it.
