100 feet tall, thick symmetrical branches, over an acre of greenery, about a million lush leaves in all. Massive quantities of protein-rich nuts.
In 1904 a handful of Asian chestnut trees were planted in New York City at the Bronx Zoo. An Asian chestnut blight quickly destroyed over 99.99 percent of the American Chestnut population - almost all of four billion trees - annihilating at least six specialized insect species, decimating wild turkey populations, and depriving humans of a priceless resource in a single generation.
This loss represented one fourth of the tree cover in the Appalachians!
