  1. American Chestnut Story http://www.apsnet.org/online/feature/chestnut/ Actual American Chestnut Tree from Mt. Airy, MD Section Overview

  2. “Redwoods of the East” • Mature chestnuts could be 600 years old and average up to five feet in diameter and 100 feet tall • Many specimens 8-10 feet in diameter http://www.acf.org/Chestnut_history.htm

  3. Historical Significance • “…The most valuable and usable tree that ever grew in the Eastern United States.” • Used for virtually everything, such as furniture, paneling, railroad ties, telegraph poles, and fuel. http://www.apsnet.org/online/feature/chestnut/

  4. Characteristics • Fast growing – reached half ultimate height by 20th year • Only white pine and tulip poplar could grow taller • Often grew branch free for 50 feet

  5. Characteristics • Fewer knots • Straight-grained • Lighter in weight

  6. Range • Maine to Georgia and west to Ohio and Tennessee • Central Appalachian ridge tops appeared snow-capped in summer due to dense crowding of American Chestnuts’ creamy-white flowers http://www.apsnet.org/online/feature/chestnut/

  7. 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.

  8. 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

  9. 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 http://www.apsnet.org/online/feature/chestnut/

  10. Population of ChestnutsToday • Logging • Forest Fires The blight does not kill the roots, so many sprouts grow up from the stumps.

  11. 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

  12. Present Source of Chestnut Lumber • Bringing up submerged logs from lakes • Recycle barns made of chestnut • Recycle old buildings made of chestnut

  13. Other types of Chestnut Trees • Chinese – • Japanese - http://images.google.com/images?q=chinese+chestnut+tree&ie=UTF-8&oe=UTF-8&hl=en http://www.apsnet.org/online/feature/chestnut/
