I lent my mom a book before I read it and apparently right at the beginning they tell a true story about all our chestnut trees dying and it made my mother SO DEPRESSED that she couldn’t sleep and now she’s been researching chestnut trees for the past half hour looking sick
She’s right!!
Chestnut trees used to define forests in the South – some estimates say about ¼ trees was a chestnut tree. And they were huge! Growing more than 100 feet tall (with trunks more than 10 feet in diameter), they were called the “redwoods of the East.” They were a characteristic food source of the South, too. A mature chestnut tree can produce upwards of 50 lbs of nuts a year – many of these were gathered and eaten by poor families, or turned into chestnut flour and used to make “poor man’s bread.”
But, at the beginning of the 20th century, a fungus called the blight was brought over from Asia. Over the next 50 years, every single American Chestnut was infected and died. While some root systems are still alive, they’re considered functionally extinct.
People cut down huge areas of forest trying to prevent the spread of the blight and save the trees – but they failed. And now several generations have never even known the chestnut tree. We don’t even know enough to miss them.
But now, with advances in genetic technology, the chestnut trees may be coming back! Through a group scientific effort led by the American Chestnut Foundation, researchers have created a “transgenic American chestnut tree with enhanced blight tolerance” called Darling 58. Darling 58 is genetically modified to be able to coexist with the blight.
Darling 58 American chestnuts are currently being reviewed by the USDA-APHIS, EPA, and FDA. But researchers hope to be able to reintroduce them soon – one huge step towards restoring our forests.
