Chestnut oak has chestnut-like leaves with rounded teeth (no bristles) and dark, deeply furrowed bark. The acorn cap is warty. It is also known as rock oak or basket oak. (Often listed as Q. prinus in older references.)
Habitat and range
In Maryland, chestnut oak grows on dry, rocky ridges and upper slopes, often in pure stands or with other oaks. It is common in the mountains and piedmont and tolerates thin, acidic soils.
Uses and significance
The wood is used for lumber, railroad ties, and fencing. Acorns are an important wildlife food. Chestnut oak dominates many ridge-top forests and is well adapted to fire and drought.
