From Garden and Gun:
Hundreds of years ago, American chestnut trees dominated the Appalachian Mountain forest-scape. They stood an imposing 100 feet tall and eight feet wide at maturity, lived for up to 600 years, and covered an estimated 200 million acres of land from Mississippi to Maine. Carpenters prized their lumber. Farmers regaled their ability to produce cheap and nutritious feed for livestock. Gourmands crowned their nuts the world’s finest.
Then an invasive blight from East Asia arrived around 1904. The fungus attacked tree trunks and felled the giants by the tens of thousands. While lone trees survived here and there, their nuts were infertile without others to cross-pollinate them, and by 1950 American chestnuts became functionally extinct.
“The devastation represents one of the greatest recorded changes in natural plant population caused by an introduced organism in history,” says West Virginia University emeritus professor of plant pathology and former American Chestnut Foundation president William MacDonald. Had the tragedy been avoided, hikers on the iconic Appalachian Trail would not only experience a “radically different landscape” but enjoy “some very tasty treats around their fall campfires,” he says.
The ACF has spent the past seventy-five years working with various conservation agencies to crossbreed blight-resistent American chestnut trees using clippings from anomalous survivors and Chinese or Japanese varieties. (Read more.)
