An experiment in regrowing forests of the world's oldest trees led environmentalists last week to climb a nine-story tall, 2,000-year-old cypress in central Florida known as Lady Liberty.

After plucking cuttings from her crown, climbers packed them on ice and shipped the specimens overnight to the nonprofit Archangel Ancient Tree Archive's nursery in northern Michigan.

Organizers hope to root the clippings to grow genetically identical trees that will be replanted elsewhere in Florida in an effort to grow a new forest of giant cypresses.
