Chestnut Oak (Quercus montana)

Chestnut Oak Summer Leaf Chestnut Oak Fall Leaf Chestnut Oak, a member of the white oak group, is a major component of the forest along the Lost Chestnut and the Oak Hickory trails and is frequently found elsewhere at the Arboretum. Its common name reflects the resemblance of its leaves to American Chestnut. Chestnut Oak, however, has rounded teeth around the leaf margins while the leaves of American Chestnut have sharp teeth. In the fall the dark green leaves of Chestnut Oak turn yellow-brown. This oak is typically found on dry, rocky sites, often in hilly or mountainous terrain, and is frequently referred to as Rock Oak or Rock Chestnut Oak. It is not shade tolerant and may form almost pure stands. Its range in the US extends from southern Maine to Georgia, Alabama, and Mississippi and west to southeastern Michigan, southern Indiana and Illinois. In the east, it is best developed in the Appalachians and is uncommon on the coastal plain.

Chestnut Oak Acorns Chestnut Oak Bark The relatively large, brown acorns (1.5 in long) have a cup that covers less than half of the nut. Along with other oaks, these acorns contribute to mast production providing an important source of food for wildlife. The distinctive, dark, deeply ridged bark has a high content of tannins and has been used extensively for the tanning of leather. The heavy, durable wood is used for construction, fence posts, railroad ties, and fuel.
