Controlled Burns Save 1,900 Giant Sequoias from Wildfires
Controlled Burns Save 1,900 Giant Sequoias from Wildfires
US · Published Jul 25, 2026
A recent study published in *Nature Communications* highlights the critical role of controlled burns in protecting giant sequoias in California's Sierra Nevada mountains.
These ancient trees, some of which are over 3,000 years old and can grow more than 300 feet tall, are increasingly threatened by intense wildfires fueled by hotter and drier conditions.

Impact & Risks

The findings underscore the growing threat of climate change-induced wildfires to the survival of giant sequoias, which are already limited to a narrow range in California's Sierra Nevada mountains. Without intervention, the increasing frequency and intensity of wildfires could lead to the loss of these iconic trees, which are vital for biodiversity and carbon storage. The study also highlights the challenges faced by forest managers, as longer wildfire seasons and unpredictable weather conditions make it harder to conduct controlled burns safely. The 2022 incident in New Mexico, where a prescribed burn led to the state's largest wildfire, illustrates the risks involved.
