Castanea dentata is a species of chestnut tree that was native to the eastern United States before it was devastated by chestnut blight in the early 20th century. There are several synonyms for this tree species, including American chestnut, eastern chestnut, and sweet chestnut. While Castanea dentata is no longer common in the wild, efforts are being made to cultivate and restore the species. Its nuts were once an important food source for wildlife and humans alike, and its wood was prized for its strength and durability. The loss of Castanea dentata has had a significant impact on the ecology and culture of the eastern United States.
