American Chestnut Species Information
Chestnut, American (Castanea dentata)
Chestnut, American is a domestic hardwood
Location
American chestnut (Castanea dentata) is also known as sweet chestnut.
Before this species was attacked by a blight in the 1920s,
it grew in commercial quantities from New England to northern
Georgia. Practically all standing chestnut has been killed
by blight, and most supplies of the lumber come from salvaged
timbers. Because of the species’ natural resistance to
decay, standing dead trees in the Appalachian Mountains continued
to provide substantial quantities of lumber for several decades
after the blight, but this source is now exhausted.
Characteristics
The heartwood of chestnut is grayish brown or brown and darkens
with age. The sapwood is very narrow and almost white. The
wood is coarse in texture; growth rings are made conspicuous
by several rows of large, distinct pores at the beginning of
each year’s growth. Chestnut wood is moderately light
in weight, moderately hard, moderately low in strength, moderately
low in resistance to shock, and low in stiffness. It dries
well and is easy to work with tools.
Primary Uses
Chestnut was once used for poles, railroad crossties, furniture,
caskets, boxes, shingles, crates, and corestock for veneer
panels. At present, it appears most frequently as wormy chestnut
for paneling, interior woodwork, and picture frames.
