The fate of the American chestnut

The fate of the American chestnut

The loss of 4 billion trees spurred federal laws to protect native plants from disease, and efforts to find a cure for chestnut blight continue.

American chestnut trees once blanketed the east coast, with an estimated 4 billion trees spreading in dense canopies from Maine to Mississippi and Florida. These huge and ancient trees, up to 100 feet tall and 9 feet around, were awe-inspiring, the redwoods of the east coast, but with an extra perk — the nuts were edible. Chestnuts were roasted, ground into flour for cakes and bread, and stewed into puddings. The leaves of the trees were boiled down into medicinal treatments by Native Americans. The trees make appearances throughout American literature, like in Thoreau’s journal, where he considered his guilt over pelting them with rocks to shake the nuts loose while he lived in Walden woods, musing that the “old trees are our parents, and our parents’ parents, perchance.” Chestnut trees offered shade in town squares, were the wood of choice for pioneers’ log cabins, and were a mainstay of American woodcraft. In short, chestnuts were part of everyday American life. Until they weren’t.

Finding a mature American chestnut in the wild is so rare today that discoveries are reported in the national press. The trees are “technically extinct,” according to The American Chestnut Foundation. The blight that killed them off still lives in the wild and they rarely grow big enough to flower and seed, typically remaining saplings until they die. Essentially, the giant trees were reduced to shrubs by the 1950s.
