Controlled Burns Saved an Estimated 1,900 Giant Sequoias
Controlled burns saved an estimated 1,900 giant sequoias during the 2020-2021 wildfires in Sequoia National Park. This local finding is based on a single retrospective study using aerial and satellite imagery. While effective here, prescribed burns carry their own risks, as demonstrated by a burn that escaped control in 2022.
Why it matters
As high-intensity wildfires threaten giant sequoias, this local evidence suggests prescribed fire can help protect the species.
