It is comparatively rare in the North Atlantic States where it grows only near the coast.

Leaf: Alternate, simple, 5 to 9 inches long and roughly obovate in outline with bristle tipped lobes. Two forms are common: 3 lobes with shallow sinuses (common on younger trees) or 5 to 7 lobes with deeper sinuses. Often resembles a turkey foot with one very long hooked terminal lobe with two shorter lobes on the sides. Shiny green above, paler and fuzzy below.

Twig: Reddish brown in color, may be gray-pubescent (particularly rapidly growing stems such as stump sprouts) or glabrous; multiple terminal buds are dark reddish brown, pubescent, pointed and only 1/8 to 1/4 inch long, laterals buds are similar, but shorter.

Fire Effects on Southern Red Oak

In general, southern red and cherrybark oaks up to 3 inches (7.6 cm) in d.b.h. are top-killed by low-severity fire. High-severity fire can top-kill larger trees and may kill rootstocks as well.
