Description
The American Chestnut was once the defining monarch of the eastern North American forest, a majestic deciduous tree known for its rapid growth, valuable timber, and abundant sweet nuts. The leaves are characteristically elongated, sharply toothed, and tapered at both ends, contributing to a dense canopy that supported an entire ecosystem before the devastating introduction of the fungal blight.
Habitat
Well-drained, acidic upland soils in mixed deciduous forests, historically dominant across the Appalachian mountain ranges
Native Range
Native to eastern North America, historically ranging from Maine to Mississippi, though now largely restricted to stump sprouts due to the chestnut blight
