Giant sequoias and California redwoods are nature's skyscrapers. But the towering trees are dying in droves, as wildfires burn bigger, hotter and longer. Now, what's growing in a greenhouse in northern Michigan could help save the species. "The real goal for me is to protect and propagate as many different species as we can," said Jared Milarch with the Archangel Ancient Tree Archive. Milarch and the team at Archangel Ancient Tree Archives are in a race against climate change and the toll it's taking on ancient trees. They collect samples from sequoias and redwoods, clone them, then replant them in places that need to be reforested The Castle Fire in 2020 ripped through the Southern Sierra Nevada and claimed an estimated 10% of the world's giant sequoias and one of the largest redwoods left in California called the Waterfall Tree. "So, the Waterfall Tree is a great example of why we're in a hurry to do this. We collected genetics from that a few years ago. We actually were able to take some of those clones and give them back to the community there to replant," continued Milarch.
