This formerly important forest tree has been nearly exterminated throughout its natural range by the chestnut blight, a parasitic fungus introduced from abroad and first noted in Michigan about 1930. Stump sprouts, which do not grow to maturity, are known at some places, and rarely, isolated healthy trees of considerable size may survive in forests. Chestnut was originally found in Michigan only in forests (especially with oaks) in the southeastern edge of the Lower Peninsula, from Monroe Co. north to St. Clair Co.
Where planted along roadsides and in orchards beyond its original native range, some chestnuts have escaped the blight and have grown to a large size. Records mapped from beyond the native range in southeast Michigan are plants that have spread from such planted specimens.
The leaves resemble large, elongate ones of beech in having straight lateral veins each terminating in a single tooth, but the teeth are longer and the veins more often glabrous or very sparsely hairy beneath.
