Ecology and uses

The acorns of dwarf chinkapin oak are sweet tasting and relished by humans and many kinds of wildlife, such as deer, turkeys, squirrels, chipmunks, and mice, each reliant on the nutritional value of chestnut oak acorns as a component of their diet. The wood has little commercial value because of the shrub's small size.
