At the turn of the 20th century, the American chestnut towered over other trees in Eastern forests. The trees would grow as much as 100 feet high, and 13 feet wide. According to legend, a squirrel could scamper from New England to Georgia on the canopies of American chestnuts, never touching the ground.

And then, the trees began to disappear, succumbing to a mysterious fungus. The fungus first appeared in New York City in 1904—and then it spread. By the 1950s, the fungus had wiped out billions of trees, and effectively finished off the American chestnut.

Now, some people are trying to resurrect the American chestnut—and soon. But not everyone thinks that’s a good idea.

Sara Fitzsimmons is Director of Restoration, North Central Regional Science Coordinator, and Regional Science Coordinator Supervisor at the American Chestnut Foundation.

Susan Freinkel is the author of American Chestnut: The Life, Death, and Rebirth of a Perfect Tree.
