During the last ice age, bald cypresses grew in what was then a swamp a hundred miles from the ocean.

They were able to remove English ivy that covered most of a champion bald cypress tree.

The population drastically declined when its host trees, 1,000-year-old bald cypresses, were logged in World War Two to provide lumber for aircraft carrier decks.

They’re also being planted alongside native trees like sweet gum, tulip trees and bald cypress, to avoid genetically identical stands of trees known as monocultures; non-engineered poplars are being planted as experimental controls.

The living trees are also impressively enduring: In 2019, a North Carolina bald cypress was determined to be more than 2,600 years old.
