Giant Sequoia Lands Coalition Releases 2025 Progress Report, Showing Accelerating Restoration Efforts

April 3, 2026 – The Giant Sequoia Lands Coalition (GSLC) released its 2025 Progress Report, showcasing significant advances in protecting the world’s remaining giant sequoia groves from shifting climates, catastrophic wildfire and emerging threats such as bark beetles. GSLC partners have conducted restoration activities in 44 of the world’s 94 sequoia groves since 2022, reducing the risk of extreme wildfires and improving overall forest health. In 2025, Coalition members conducted forest resilience treatments on 4,508 acres across 25 groves, advancing the momentum of this collaborative effort. Since its formation following the devastating 2020 and 2021 fire seasons—when the Castle Fire, KNP Complex Fire and Windy Fire killed thousands of ancient sequoias—the Coalition has treated a total of 23,251 acres and planted more than 682,000 native trees.  

Additionally, a new scientific study from the GSLC reveals the current state of California’s giant sequoia range and quantifies the alarming extent of damage caused by extreme wildfires over the last decade. More than 17% of all mature giant sequoias have been killed by wildfire since 2015, while less than 1% perished in the 30 prior years. Most of the losses since 2015 occurred during the megafires of 2020 and 2021.
