In 2021, firefighters in California took extraordinary measures to protect the world's largest tree, General Sherman, from the encroaching KNP Complex Fire in Sequoia National Park. This ancient sequoia, standing 275 feet tall and estimated to be over 2,200 years old, was wrapped in a fire-resistant aluminum-based blanket to shield it from intense heat and potential ignition. The material, developed by FireZat Inc., is designed to reflect up to 96% of radiant heat, providing a protective barrier against flames . This technique, commonly used to protect structures, was adapted to safeguard these towering trees, which are vital to the ecosystem and hold significant cultural value. In addition to wrapping, crews removed combustible materials from the forest floor and conducted controlled burns to reduce fuel loads, aiming to steer the wildfire away from the Giant Forest, home to over 2,000 sequoias . While wildfires are a natural part of the sequoia's life cycle, the increasing frequency and intensity of such fires, exacerbated by climate change, pose unprecedented threats to these ancient giants. The protective wrapping and other mitigation efforts exemplify the innovative strategies being employed to preserve these irreplaceable natural wonders for future generations
