Ecology & Natural History

Habitat: Species is distributed at borders of woods and fields; well-drained soil along streams; upper slopes, ridges.

ILPIN Notes: Form - whips, seeds. Wood is heavy, hard, and strong, but it is not tough and tends toward checking during drying. Species has pistillate flowers in groups of 1-4; large, angular gray-hairy buds; acorns with a ragged-edged cup; 7-9 bristle tipped lobes; leaves finely hairy on lower surface, dark outer bark, inner bark yellow or orange. Seed company number 28. Species maybe causes hayfever; inner bark yields a yellow dye, also sometimes used as an astringent; bark is rich in tannic acid and used for tanning leather; fruit is edible after preparation. Marshbirds and shorebirds eat acorns as food; terrestrial furbearers (esp. raccoons, tree squirrels) eat food such as acorns, bark, wood; also good den tree. Regarding waterfowl food value, this pertains especially to wood ducks.

Regarding small mammals food value, this pertains especially to eastern chipmunks, white-footed mice. Young branchlets and lower surface of leaves are permanently pubescent.
