In 1994, a park ranger roped down into a canyon near Sydney; what he discovered there were trees that had been extinct for millions of years

The Wollemi pine, a species long considered extinct, was surprisingly discovered by David Noble in the Wollemi National Park in 1994. Identified scientifically as Wollemia nobilis, this tree has become a key target for conservationists. Notably, just 45 mature trees remain in their natural habitat, facing numerous risks like climate change and wildfires.
