Chinkapin oak (Quercus muehlenbergii), sometimes called yellow chestnut oak, rock oak, or yellow oak, grows in alkaline soils on limestone outcrops and well-drained slopes of the uplands, usually with other hardwoods. It seldom grows in size or abundance to be commercially important, but the heavy wood makes excellent fuel. The acorns are sweet and are eaten by several kinds of animals and birds.
