The American Chestnut Foundation (TACF) work to restore the American chestnut tree to its native US habitat and ACF.org is where their efforts are chronicled online. After many chestnut trees succumbed to the chestnut blight, (a lethal fungus infestation), The American Chestnut Foundation was founded by plant scientists who wished to bring back the chestnut tree. The ACF realized that losing the chestnut tree had negative effects on not only the ecology of forests but also on the local economy of rural communities. The American chestnut was a crucial part of the ecosystem on the Eastern United States as well as being the most important source of food for wildlife in the area, including birds and bears.
Through a backcross breeding program which crossed the American chestnut tree with Chinese chestnut trees, the American trees became blight resistant. The research facility has planted over 160 acres of American chestnuts trees and they currently have more than 30,000 trees at their farm. ACF.org provides extensive information about the TACF, (The American Chestnut Foundation), and their work with restoring the American chestnut.
