Angel Oak
Angel Oak is a Southern live oak ("Quercus virginiana") located in Angel Oak Park on Johns Island near Charleston, South Carolina. The tree is estimated to be 400-500 years old. It stands 66.5 ft (20 m) tall, measures 28 ft (8.5 m) in circumference, and produces shade that covers 17,200 square feet (1,600 m). Its longest branch distance is 187 ft in length. Angel Oak was the 210th tree to be registered with the Live Oak Society.
The oak derives its name from the estate of Justus Angel and his wife, Martha Waight Tucker Angel. Local folklore tells stories of ghosts of former slaves appearing as angels around the tree.
Ulmus americana
New York City's Central Park is home to approximately 1,200 American elms, which constitute over half of all trees in the park. The oldest of these elms were planted during the 1860s by Frederick Law Olmsted, making them among the oldest stands of American elms in the world. The trees are particularly noteworthy along the Mall and Literary Walk, where four lines of American elms dramatically stretch over the walkway forming a cathedral-like covering. The elms are an important part of New York City's ecology by improving air and water quality, reducing erosion and flooding, and lowering the air temperature during the hottest days of the year.
