Morphological Description of Oak Trees

Oak trees are large, long-lived hardwood species that can reach heights of 20–40 meters, with broad canopies, upright trunks, and thick, rugged bark with deep fissures. The expansive canopy and robust branches give the oak its proud and majestic form.

Oak leaves are usually elongated or ovate, with deeply lobed or serrated margins, dark green in summer, turning to vibrant yellow and red hues in autumn, creating breathtaking scenery in temperate regions.
