Anotations

Scope note:

Species of large, deciduous timber and forest tree originally found throughout North America. However, a fungus, Oriental chestnut blight, imported in the early part of the 20th century killed most of the trees. Before the species was devastated, it was one of the most important forest trees throughout its range. There are now very few mature specimens of the tree within its historical range, although many small sprouts of the former live trees remain.
