Fortunately, the Woolemi pine is easily propagated. Its future is secure. We have several (I think) at the Eden Project in Cornwall. Another brought back from the brink is the Dawn Redwood, Metasequoia glyptostroboides. It is the only surviving species of the genus Metasequoia, a genus previously thought to be extinct for over a hundred million years. s you could guess from the name, it's related to the giant redwoods. It was found in a small area of China in the 1940s, but it's threatened in its only known native habitat by land degradation and over-collecting of seeds. Luckily, it's also very easy to propagate, and it grows into a beautiful specimen tree.
