Habitat

• Common on moderate slopes and other moderately dry soils

• Can basically live in all soil types, as long as it is not too wet.

Ecological Importance

• Wildlife depended on the abundant crop of chestnuts (birds, bears, squirrels)

• Many species of insects fed on the leaves, flowers, and nuts

• Livestock, particularly pigs, used as a source of fat

• Humans used as a cash crop, especially around the holidays

Demise of the Native American Chestnut

• In 1904, cankers were evident in New York City

• By 1926, the fungus was reported throughout the native range

• Some trees were still blight free due to isolation until cankers were found in 1986

Population of ChestnutsToday

• Logging• Forest Fires

The blight does not kill the roots, so many sprouts

grow up from the stumps.

Sprouts from Old Stumps

• Sprouts will grow up from the stumps

• Many will die due to the blight and the cycle will repeat

• Some of the sprouts may become the size of a small tree

Present Source of Chestnut Lumber

• Bringing up submerged logs from lakes

• Recycle barns made of chestnut

• Recycle old buildings made of chestnut
