American chestnut

American chestnut Castanes dentate

Description

A large, deciduous tree, Castanea dentata, that formerly grew throughout North America. However, a fungus, Oriental chestnut blight, imported in the early part of the 20th century killed most of the trees. Timber from the American chestnut is similar to oak with a light brown, coarse grain. The durable wood was widely used prior to World War II for paneling, framing, fence posts, rails, and shingles. Dyes and tannin are extracted from the bark and wood.
