The height and circumference measurements listed above are for the largest-known swamp chestnut oak tree in Atlanta. This tree is located at Clear Creek Nature Preserve in Brookwood Hills. Chestnut oaks are uncommon in Atlanta.
Note that this is a different species from the chestnut oak (Quercus prinus).
Acorns are about 1-1/4 inches long.
The decay-resistant wood of the chestnut oak was used for fence posts. The bark was highly prized for its tannin content; in the colonial days, it was used extensively for tanning hides.
