At the turn of the 20th century, the American Chestnut tree was the most important plant in the eastern United States, accounting for over 25% of the forest canopy. But in a period of just 50 years, a mysterious blight, an imported fungus, swept the country and killed over four billion trees.

Join Jason Epperson for Parkography as we explore the rise and fall of the majestic American Chestnut and the incredible, ongoing effort to bring the species back. A major part of this mission is taking place on one of our nation’s most hallowed grounds: the Flight 93 National Memorial in Shanksville, Pennsylvania.

Learn about the tree's vital role in the American landscape and economy, the devastating chestnut blight, and the pioneering "backcross" technique scientists and volunteers are using to plant blight-resistant seedlings in the memory of American heroes.
