When a storm last winter toppled the Pioneer Cabin Tree, an iconic “drive- through sequoia” in Calaveras Big Trees State Park, the news and grief spread across the nation in media from the Los Angeles Times to The New York Times. The 1,000-year-old giant sequoia was famous for the car-sized tunnel cut through its trunk in the late 1800s to attract tourists.

Last winter’s intense wind and rain brought down giants throughout the redwood range, including the 1,000-year-old Advocate Tree in the Forest of Nisene Marks near Santa Cruz, and a 300-footer in Prairie Creek Redwoods State Park near Klamath.

It is true that seeing any of these towering giants fall is sad for us because we have so few left. Only 5 percent of the original old-growth coast redwood forest remains along the California coastline between Big Sur and the Oregon border, and the last remaining giant sequoia live in scattered groves along the western slopes of the Sierra Nevada. But under the surface of the sadness lies a brighter, long-term scientific view.

When a giant redwood falls, it begins a critical phase in the forest lifecycle, contributing to the environment in different ways. Critical to biodiversity, they create gaps in the canopy, bringing light to the forest floor for younger trees to thrive. They provide habitat for a wide variety of wildlife, from insects to black bears. Trees that have fallen into and across streams provide calm pools and new shaded habitat, perfect for imperiled fish such as coho salmon and steelhead trout.

Downed trees also provide recycled nutrients for new herbaceous plants, mosses, lichens, fungi and other trees. And because redwood is extremely slow to decay, the large amounts of carbon that the tree absorbed while alive will remain in its wood for decades, if not centuries, allowing the fallen giant to continue to play a lead role in the climate change solution.

With your support, Save the Redwoods League can work hard to make redwood habitats as healthy as possible. Our broad-scale forest restoration projects in the next 100 years will strive to link old-growth groves to protected, regenerating forest, creating conditions for massive redwoods to grow in much larger areas. Yes, trees will still fall, but for future generations, these events will reflect the dynamic nature of a healthy forest. If we commit to our work as stewards of the world’s most superlative forest, young forests will heal and become forests of giants, standing tall in an intact ecosystem, the likes of which we have never seen in modern times.

Thanks to our generous donors, California voters and the State of California Wildlife Conservation Board (WCB), Save the Redwoods League is set to complete the first phase of our Mailliard Ranch project, which protects three-quarters of this majestic property from development and subdivision. Protection of the ranch will secure the stability of the regional forest ecosystem.


Emily Burns, PhD, League Director of Science, reaches for the captivating cream-colored needles of an albino sprout growing out of a redwood. “It lacks chlorophyll, so it’s white, and it’s caused by a mutation on that particular sprout’s DNA,” she said. Further genomic research could confirm hypotheses that albino sprouts are more than parasites. It’s clear that the deeper we go into the redwood genome, the more we’ll know.

Save the Redwoods League is leading research to fully sequence the coast redwood and giant sequoia genomes — for the first time — utilizing conifer genetic sequencing techniques unavailable until now. By the end of this five-year project, the genome sequences and the screening tools developed will allow researchers to quickly assess genetic diversity in redwood forests to inform management plans that restore the health and resilience of these forests throughout their natural ranges as they face environmental stressors such as climate change.
