Oak is a type of tree known for its strength and durability. These trees can grow very tall and live for hundreds of years. Oak wood is often used in furniture and flooring because it is hard and resistant to wear. The leaves of oak trees are usually lobed and turn beautiful colors in the fall, making them a favorite among nature lovers. In addition to their practical uses, oaks provide important habitats for wildlife. Many animals, such as squirrels and birds, rely on oak trees for food and shelter. The acorns produced by oaks are a vital food source for creatures like deer and wild turkeys, making these trees essential to the ecosystem.
