(SOUNDBITE OF SONG, "THE CHRISTMAS SONG")
NAT KING COLE: (Singing) Chestnuts roasting on an open fire.
AUDIE CORNISH, HOST:
It's actually pretty difficult these days to find anyone roasting American chestnuts over an open fire. That's because American chestnut trees have all but disappeared. So scientists were excited to discover one in the woods of western Maine, a record-breaking tree that's giving them hope for the future. From Maine Public Radio, Susan Sharon reports.
SUSAN SHARON, BYLINE: Growing straight and tall, chestnut trees were once prized for timber. Vendors still roast and sell European chestnuts on the streets of Manhattan - fragrant aroma and all. But the American chestnut, which once dominated the eastern woodlands from Maine to Georgia, was virtually wiped out by a blight that was accidentally introduced from Asia. That's why on a recent rainy December day, a gaggle of reporters, photographers and members of the American Chestnut Foundation trudged into the woods of Lovell, Maine, to confirm some crucial measurements of a chestnut tree growing in the wild.
UNIDENTIFIED MAN: I have 16.1 inches.
UNIDENTIFIED MAN: Yes.
SHARON: As girth goes, this chestnut tree is not impressive. It's on the skinny side. Except for its long, slender leaves and spiny urchin-like burrs, most people wouldn't pick it out as distinctive in a forest lineup, especially this time of year when both the leaves and the burrs are littering the ground. But Dr. Brian Roth, a forest scientist with the University of Maine, says when it comes to height, this American chestnut reigns supreme.
BRIAN ROTH: We think it's around 100 years old. It's over a hundred feet tall, which makes it the tallest tree that we know of in North America.
SHARON: One hundred fifteen feet tall to be precise. But beyond its exceptional height, Roth and members of the American Chestnut Foundation are interested in this chestnut because of its ability to survive. Surrounded by a cluster of equally tall pine trees, it was discovered in July from the air, distinguished by the large, white flowers in its crown.
ROTH: Old-timers talk about the hillsides in the Appalachian Mountains being covered in flowers as if it was snow. And so we were able to key in on the particular week that these were blooming and did find this tree.
SHARON: Roth says DNA from the tree will be preserved in a living gene bank. It's all part of a larger effort by the North Carolina-based American Chestnut Foundation to restore the chestnut to its historic range. With the help of 6,000 devoted volunteers, the foundation has developed a complex breeding program to raise a hearty American chestnut that is resistant to the fungus and that can someday be reintroduced to the wild.
LISA THOMSON: It's an underdog. You know, everybody loves an underdog. And they see hope in the future, real promise of the future to bring this species back.
SHARON: Foundation president Lisa Thomson says she and her volunteers won't see a Cathedral of chestnuts in the forest in their lifetimes, but their grandchildren will and that's enough of a vision to keep them singing the chestnut's song. For NPR News, I'm Susan Sharon.
