Protecting Giant Sequoias Through Knowledge and Partnership
With every survey, our world learns more about the wonders of giant sequoia trees. But as we face growing threats of invasive species, extreme drought, and intense wildfires, we must also understand how these threats impact the trees and vital ecosystems they support.
For researchers, analysts, reporters, and anyone looking for some of the latest data on giant sequoias, we’ve gathered resources and partner links to help you navigate the landscape.
If you want to share a resource or report with our coalition members, please get in touch with us.

Research Partners
Berkeley Forests Research Area
Home to some of the world’s foremost research on climate change, water, wildfire, wildlife, invasive species, and silviculture, Berkeley Forests welcomes the opportunity to work with new research partners and to host new research endeavors on their research forest properties.
Stephens Lab
The mission of the Fire Science Laboratory at the University of California Berkeley is to conduct scientific research and provide academic training in the fields of wildland fire science, ecology, and resource management. Visit site to learn more and read recent publications.
Save The Redwoods League
Save The Redwoods League is a nonprofit organization whose mission is to protect and restore California redwoods and connect people to the peace and beauty of redwood forests. Visit site to learn more and view recent blog posts.
Ancient Forest Society
The Ancient Forest Society is a non-profit organization working to study and protect ancient trees and forests in a time of rapid environmental change. Ancient Forest Society is leading a two-year study examining bark beetle attack in giant sequoia trees in collaboration with scientists from Colorado State University. The study is funded by the CAL FIRE Forest Health Research Program and will take place in four different locations: Calaveras Big Trees State Park, Yosemite National Park, Sequoia National Park and Mountain Home Demonstration State Forest.
Reports & Research Papers
Ancient trees and modern wildfires: Declining resilience to wildfire in the highly fire-adapted giant sequoia – Published in Forest Ecology and Management, this 2022 examines the impacts of fire severity on morality rates of giant sequoias, with joint research from USDA Forest Service, Pacific Southwest Region Ecology Program; USDA Forest Service, Rocky Mountain Research Station; University of California Davis; the Nature Conservancy; and Save The Redwoods League.
The 2021 Fire Season Impacts to Giant Sequoias – The 2021 fire season included two large wildfires that burned into a large number of giant sequoia groves. All of the data, data analysis, maps and modeling contained in this report are excerpted from the Burned Area Emergency Response Plan for the KNP Complex authored by the National Park Service.

2025 Progress Report for Saving the Sequoias
2024 Progress Report for Saving the Sequoias
2023 Progress Report for Saving the Sequoias — In its second year of large-scale collaboration, Giant Sequoia Lands Coalition more than doubled the acres across the giant sequoia range where restoration treatments are underway to protect the ecosystem from severe wildfires
2022 Progress Report for Saving the Sequoias — In its first year of large-scale collaboration, Giant Sequoia Lands Coalition far exceeded its goals in helping to protect the giant sequoia range from severe wildfires, treating more than double the acres originally targeted for restoration in 2022.

Documenting the Giants
The State of the Giant Sequoias: Losses, Risks and Opportunities – This new report underscores the urgent need for expanded restoration and resilience treatments to protect these iconic groves from the dual threats of shifting climates and local extinction.
Yosemite Nature Notes 34: Giant Sequoias – Produced by the National Park Service in 2022, this short documentary provides an overview of giant sequoias. Giant sequoia trees are impressive in size, age, and resilience. This resilience is being tested by climate change and previous management practices. These challenges offer opportunities to research these wonderful trees and develop better ways to support their ability to thrive.
The Last of the Monarchs – In this short documentary, hear from those working on the frontlines of climate change in the Sierra Nevada as they share their perspectives on how wildfire and climate changes are adding new pressures to the survival of sequoia trees.
Wildfires Are Putting Giant Sequoias at Existential Risk – This short documentary highlights the impact of intense wildfires on giant sequoia ecosystems. Researchers from the University of California, Berkeley are studying the effects of record-breaking fires such as the one that destroyed large swaths of Alder Creek Grove in the hopes that their findings will inform forest management that might preserve giant sequoias for future generations.
Celebrating Earth Day from the sequoia treetops – ABC News’ Kayna Whitworth joins scientists and arborists using ropes to climb up sequoias, allowing them to access tree canopies and check for decay as forests face threats from climate change.
‘Good Morning America’ takes a look at some of the country’s majestic forests for Earth Day – Scientists and arborists use ropes to climb up sequoia trees, allowing them to access tree canopies and check for decay.
"We know more about sequoias than ever before, and more importantly, we are able to reach, inspire, and engage people around the globe better than we ever have before."
