Summary:
- Scientists are working to save the Wollemi pine, a rare "living fossil" tree species found in a remote canyon in Australia, from a fast-spreading fungal disease.
- The Wollemi pine is considered a "living fossil" because it has remained unchanged for millions of years, dating back to the time of the dinosaurs.
- The fungal disease is threatening the small population of Wollemi pines, and researchers are using a combination of fungicides, monitoring, and other conservation efforts to try to protect this unique and ancient tree species.
