Oaks are large trees belonging to the genus Quercus, which includes over 600 species. They are known for their strong wood and distinctive lobed leaves. Oaks can be found in various habitats, from forests to grasslands, and are native to many regions around the world, particularly in the Northern Hemisphere. These trees produce acorns, which are a vital food source for many animals, including squirrels and birds. Oaks also play an important role in their ecosystems by providing shade and shelter. Their longevity and strength make them a popular choice for landscaping and timber production.
