Thanks to a worldwide effort to conserve and propagate the Wollemi pine—one of the oldest and rarest tree species on earth—a recently purchased foot-tall Wollemi seedling now has a home at the UW–Madison botany greenhouses at Birge Hall. The relic tree species, dating back 90 million years to the age of the dinosaurs and once known to botanists only through fossils, was discovered in an Australian national park in 1994. A limited number of the plants just became available in the United States through National Geographic. Images credit: Jeff Miller Photos date: December 2006
