Chestnut Oak

Arbor Walk #152, Treekeeper ID #6051

The Chestnut Oak has a native range just bordering but not within Missouri; it thrives in dry uplands from southern Maine to the Mississippi but primarily in the Appalachian Mountains. While the Chestnut Oak is similar in leaf shape to the Swamp Chestnut Oak and Chinkapin Oak, but has pale green on the leaf underside unlike the white underside of Swamp Chestnut Oak, and deeply ridged bark unlike the shaggy bark of the Chinkapin Oak. Unlike the Swamp Chestnut Oak, it prefers drier and more elevated sites.

The Chestnut Oak is a member of the subgenus of white oaks. These oaks are distinguishable from other oaks from their smooth lobe tips (no awns), their hairless leaf undersides, and their lighter, flakier bark. The acorns of white oaks are also less tannic, meaning that they require less processing to become safe and palatable.
