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
