The long-living bur oak has broad-spreading branches and develops thick bark tolerant of once-common prairie fires. Its large acorns have a fringed burry cup, can grow one-and-a-half-inches long, and serve as an important food source for many birds and small mammals. The tree features thick, round-lobed, green leaves that turn amber in the fall. Many insects, birds, and squirrels use the tree’s bark, stems, and foliage for shelter.
