The Georgia Ports Authority is making an Arbor Day promise to protect some ancient live oak trees at the site of one of America's busiest shipping terminals.

Officials at the Port of Savannah planned Friday to place a plaque at the foot of one of the oaks — a tree one expert has estimated is more than 360 years old. That would mean the tree was more than 80 years old in 1733, when Georgia was founded as the 13th British colony at Savannah.

The trees are located at the Savannah port's Garden City terminal — the hub of activity at the nation's 4th busiest container port. Still, port officials say they have placed the trees under protective governance, meaning they won't be harmed.
