MILE AFTER MILE

We traverse dense shrublands in Redwood Mountain Grove, searching for giant sequoia seedlings and working our way toward the next research plot. Diverse topography and tangled vegetation make even short distances demanding. Some days, our progress is measured as much in effort as in plots checked off the to-do list.

Relatively few people spend their days this far into burned forests, gathering the field data needed to understand their ecology. Every plot we reach adds to that understanding: how giant sequoias regenerate after fire, how quickly they grow, how they live among the tall shrubs surrounding them... a never-ending list of questions grounded in a curiosity that builds our relationships with these beautifully burned ecosystems.

Four years after fire, our research team documented an average of nearly 8,000 giant sequoias per acre in the grove's largest high-severity patches. Within those patches, giant sequoias grew vigorously among dense shrub cover. The vegetation that makes our passage so difficult is an essential component of this thriving forest community and is full of biodiversity.

Between plots, islands of fallen giant sequoia bark offer reprieve from the tangle. We set down our packs and catch our breath beneath the snags. As the sun moves across the sky, their shadows shift across the bark, offering moments of shade before moving on.

From these small resting places, we look across the landscape at giant sequoia seedlings and saplings growing among shrubs and beneath the standing remains of an older generation. Then, we shoulder our packs and continue. Occasionally, a long strip of fallen bark offers a walkway through the messy habitat, briefly easing our passage, if only for a moment.

Mile after mile, we are documenting a remarkable chapter in this groves history and getting to know these ecosystems. Follow along as we explore questions few have asked and showcase the wild beauty of a burned forest that hasn't been witnessed in centuries.

HIGH-SEVERITY FIRE PATCHES 🌲 🔥 🪾

Across giant sequoia groves, we have documented extraordinary regeneration in large high-severity fire patches. In Redwood Mountain Grove, our research found more than 19,000 sequoia seedlings and saplings per hectare four years after fire. By five years, our field observations included young sequoias over 13 feet tall.

Lower-severity fire can also trigger an initial pulse of seedlings, but germination alone does not ensure a groves future. Beneath a largely intact canopy, insufficient conditions limit growth and survival. Large high-severity fire patches create extensive canopy openings and the conditions that support abundant regeneration, rapid growth, and the potential for successful recruitment into the next generation of canopy trees.

Fuels reduction logging and widespread prescribed burning cannot eliminate future high-severity fire, nor should eliminating it be the goal. Continually trying to prevent intense fire risks limiting the opportunities that sustain these forests. Protecting aging giants while preventing the generations that replace them could leave groves on a path toward gradual disappearance.

"We're seeing the most extraordinary natural regeneration of giant sequoia forests that any human beings have seen since the late eighteen hundreds." – Dr. Chad Hanson, Wildfire Scientist

We are privileged to witness—and study—the ecological processes that foster forests that live for thousands of years. Protecting these forests means allowing them to become young again and recognizing that intense fire is a beautiful part of their story.

CONE FORMATION

At just three years old, Moran and Huebner (2025) documented a developing cone on a giant sequoia barely two feet tall. During our own field research, specifically in large, high-severity fire patches, we've found numerous sequoia seedlings developing cones as well.

Why does this matter? If young trees produce fertile seeds, they could help sustain sequoia populations during periods of increased fire activity. Even if early cone formation is relatively uncommon, trees that reproduce sooner could have a better chance of leaving descendants—potentially making that ability more common over generations and increasing the odds of population persistence.

These tiny cones open big questions about how giant sequoias endure during periods of climatic variability and how much we still have to learn. Visit our website to learn more about the science behind giant sequoia regeneration.

A Day in the Life of Wildfire Scientists 🔥

It is difficult, beautiful work. Soot on our hands. Shrubs over our heads. Scratches across our arms and legs. A new generation of giants rising at our feet.

As wildfire scientists, we have the rare privilege of witnessing giant sequoia seedlings emerging after high-severity fire—a remarkable process shaped by tens of millions of years of evolution, giving rise to trees that may outlive us by thousands of years.

Our days take us bushwhacking through dense shrublands and across steep terrain. Black-backed woodpeckers drum against charred trunks. Wildlife tracks create paths through ash-softened Earth. Wildflowers bloom, buzzing with life. Young sequoias thrive where fire burned hottest. And as daylight fades, spotted owls call beneath the stars.

The beauty of these burned forests exists in its own right, independent of the life that follows. Even before the first seedling emerges, they are no less worthy of wonder.

Few people have witnessed this remarkable chapter in giant sequoia history, and fewer still have studied it so closely. Through demanding fieldwork, we're documenting the intricate relationships between fire, forest regeneration, and the extraordinary diversity of life these ecosystems sustain.

We study these forests not to find new ways to manipulate them, but to better know our neighbors. Every observation adds to our understanding. Every day deepens our connection.

For now, we kneel beside the seedlings, take our measurements, and listen. Visit our website and blog to learn more about our science.

ROADLESS RULE COMMENTS DUE

Use your voice to oppose rescission of the Roadless Rule today. But don't stop there. Let's advocate for closing the logging loopholes that leave these areas vulnerable to destructive management activities, such as so-called "fuels reduction projects."

Ultimately, our remaining roadless areas deserve something stronger and more permanent—Wilderness protection.

Together, we can strengthen protections for these last wild places. Read our Roadless Rule blog below to learn more about the loophole and be sure to submit your comments by midnight eastern time today.

LIFE AFTER FIRE 🔥

Step inside a snag forest and discover the incredible life that emerges after high-intensity fire—from black-backed woodpeckers to millions of giant sequoia seedlings and saplings growing rapidly across the forest floor.

This beautifully-made video takes you through an important stage of forest succession and showcases how forest management is degrading wild ecosystems and killing vast swaths of young giant sequoias. In Freeman Creek Grove alone, we estimated that the Giant Sequoia Lands Coalition has already killed over 158,000 naturally regenerating giant sequoias.

Watch the full video on YouTube to explore why this complex post-fire habitat is an essential component of forest ecosystems.

Note: While this video brings important attention to snag forest habitats, we disagree with the closing report (by American Forests/Cal Fire) regarding projected forest loss and the need for action, which doesn't align with the full body of scientific evidence.

WHEN LOGGING IS SOLD AS A CLIMATE SOLUTION

A recent "Boiling Point" episode, featuring wildfire scientist Dr. Chad Hanson, left out a major part of the climate conversation as other voices promoted forest "thinning" as a way to reduce wildfire impacts.

Listeners weren't given the full picture, including research on the climate impacts of logging and the full scope of science on fire severity, historical forest conditions, and post-fire regeneration pathways.

There's much more to this story, and to the science. Read our full response at a link below (or in our bio).

FIVE YEARS AFTER FIRE

This is what it looks like to study giant sequoia natural regeneration following high-intensity fire. Mile after mile, our team of scientists push the limits to gain valuable insights about the natural processes that shape these forests.

Dense, episodic montane chaparral fills the landscape—an extremely biodiverse stage of forest succession that flourishes in the sunlight created by intense fire. These temporary shrublands provide essential habitat for a remarkable diversity of species.

The shrubs are so dense that our research team nearly disappears while navigating from plot to plot. But what you can't easily see are the countless giant sequoia seedlings and saplings growing beneath and through them.

Our research consistently finds significantly higher giant sequoia reproduction in areas with the highest shrub cover, including sequoias thriving amid 100% shrub cover. There's an entire forest growing beneath the chaparral.

Learn more about our giant sequoia research and our work to protect these groves on our website below!
