Pin Oak
Quercus palustris

The mature tree is distinctive from a distance with its ascending upper branches, horizontal middle branches, and drooping lower branches. The round acorns are the smallest of Ohio's oak trees. The Pin Oak grows in wet, often poorly drained soils of bottomlands and swamps. Although widely distributed throughout Ohio, it probably is most abundant in the southwestern part of the state. The strong, close-grained woods warps and checks badly in drying and has limited uses. Various wildlife, including Wood Ducks, feed on the acorns.
