The white oak is one of our most important, largest, longest- lived and mostvaluable timber trees. It grows to 100 feet in height and 3 to 4 feet in diameter. In the timber it forms a tall, straight tree, but in the open it is wide andspreading. Found over all of the eastern UnitedStates and widely over Iowaexcept the northwestern part, it occurs on a wide variety of soils, but usuallyon upland clay soils. The single leaves are 4 to 7 inches long and about half as broad,deeply divided into seven to nine rounded, finger-like lobes.
