The Great Dismal Swamp is a 126,000 acre preserve that straddles Virginia’s border with North Carolina. It’s linked all the way to Florida by the Intracoastal Waterway, and a senior biologist with the U.S. Fish and Wildlife Service says alligators are moving north.
“Used to be about 60 miles south of us. Now they’re probably within 15-20 miles of our southern border.”
American Chestnut trees used make up twenty-five percent of the Appalachian forest. A blight, in the early 1900s changed that, and today they’re all but gone from the forests from Georgia to Maine.
