It is sometimes called yellow oak, quercitron, yellowbark oak, or smoothbark oak. It grows best on moist, rich, well-drained soils, but it is often found on poor, dry, sandy or heavy glacial clay hillsides where it seldom lives more than 200 years. Good crops of acorns provide wildlife with food. The wood, commercially valuable for furniture and flooring, is sold as red oak. Black oak is seldom used for landscaping. The Silviculture of Black Oak JeannetteKatzir / Getty Images Black oak acorns are an important food for squirrels, white-tail deer, mice, voles, turkeys, and other birds. In Illinois, fox squirrels have been observed feeding on black oak catkins. Black oak is not extensively planted as an ornamental, but its fall color contributes greatly to the aesthetic value of oak forests.

Twig: Stout and red-brown to gray-green, usually glabrous but rapidly growing twigs may be hairy; buds are very large (1/4 to 1/2 inch long), buff-colored, fuzzy, pointed, and distinctly angular. Fire Effects on Black Oak NirutiStock / Getty Images Black oak is moderately resistant to fire. Small black oaks are easily top-killed by fire but sprout vigorously from the root crown. Larger black oaks can withstand low-severity surface fire because of moderately thick basal bark. They are susceptible to basal wounding.
