A Forest crop, Quercus robur was named for its sturdy nature ('robur' means 'strength' in Latin). It can take as long as 150 years before an oak is ready for use in construction. Oak became the material of choice for building ships, oak bark has been used in leather tanning and in dyeing, and the acorns are valued as food for livestock. Celts believed that doors made of oak wood kept out evil spirits. One of our largest long-lived trees, it provides an important habitat for many other species.
