Introduction
Sequoia and redwood trees are two giant species native to California. They are among Earth’s most iconic, towering trees. They’re often confused with one another, but they have distinct characteristics, habitats, and ecological significance. So what’s a sequoia versus a redwood?
Each of these remarkable trees has a unique role in its ecosystem. Both face specific challenges as climate change impacts their environments. And you can find both kinds of trees on Shaka Guide tours.
You’ll find sequoias in our Yosemite, Kings Canyon, and Sequoia tours, and you’ll find Redwood trees on our Redwood National Park tour.
What’s the difference?

The giant sequoia and coast redwood occupy distinct regions within California, each adapted to specific environmental conditions.
Giant sequoias grow only on the western slopes of the Sierra Nevada Mountains in central California. They thrive at altitudes from 4,000 to 8,000 feet.
This restricted range means sequoias inhabit a unique environment with high elevation and well-drained soils. Significant precipitation, often snow, sustains them year-round.
Due to these specific conditions, sequoias grow in roughly 70 groves covering about 48,000 acres. They thrive in areas like Sequoia and Kings Canyon National Parks.
In contrast, coast redwoods grow along a narrow, humid strip of land along California’s northern coast, extending from Big Sur to the southwestern corner of Oregon.
They thrive in the mild, foggy climate where rainfall averages around 60 to 140 inches per year. The cool coastal air and frequent summer fog provide them with essential moisture, even during California’s dry season.
Redwoods cover a broader area than sequoias, though most old-growth stands are in protected parks. Redwood National and State Parks are key conservation sites.
Why are redwoods and sequoias so big and tall?

Both the giant sequoia and coast redwood are colossal, yet they differ in height, trunk diameter, and overall mass.
Height
Coast redwoods hold the record for the tallest trees on Earth, with some individuals reaching upwards of 380 feet. The tallest known coast redwood, named Hyperion, stands at 379.7 feet.
This extreme height is due in part to the species’ rapid growth rate and access to ample coastal moisture. By comparison, sequoias can reach heights of around 250 to 300 feet.
Like redwoods, sequoias grow tall by way of a rapid growth rate and access to large amounts of moisture from snowfall.
Trunk and Mass
Giant sequoias, while not as tall as coast redwoods, are the most massive trees in the world by volume.
Their trunks are exceptionally thick, sometimes spanning 30 feet or more in diameter at the base.
The General Sherman Tree, a giant sequoia in Sequoia National Park, holds the title of the largest tree by volume. It’s over 36 feet wide at its base.
Redwoods, on the other hand, are 20 to 30 feet wide at their base.
Lifespan
Both trees are extremely long-lived. Giant sequoias can live for over 3,000 years, with the oldest recorded individuals estimated to be around 3,200 years old.
Coast redwoods have slightly shorter lifespans, often ranging between 500 to 1,800 years.

Impact of Climate Change on These Trees
Climate change presents significant challenges for both giant sequoias and coast redwoods.
As temperatures rise, California’s Sierra Nevada region experiences less snowfall and earlier snowmelt, resulting in a reduced water supply during the summer months.
Sequoias rely on consistent moisture levels throughout the year, so reduced snowpack threatens their health.
Prolonged droughts and warmer temperatures have caused more intense wildfires, overwhelming the sequoia's fire-resistant adaptations.
Recent severe fires, such as those in 2020 and 2021, destroyed thousands of mature sequoias, threatening the population's long-term survival.
Climate change impacts coast redwoods by disrupting the fog patterns that sustain them.
Warmer temperatures and shifts in atmospheric circulation can reduce the frequency and intensity of fog along California’s coast.
This makes it harder for redwoods to gather the water they need during the dry season.
Prolonged droughts increase stress on trees, making them more vulnerable to pests and diseases, which can decline in health and growth.
Importance of These Trees to California's Legacy
The towering giants of California's forests are both environmental and cultural treasures. Their conservation is crucial to maintaining California’s ecological diversity, cultural heritage, and environmental resilience.
These trees are a part of California’s identity, drawing millions of visitors each year who contribute to the state's economy.
Indigenous tribes have long revered these trees and used them for cultural and spiritual practices.
Today, redwoods and sequoias symbolize endurance and natural wonder, reminding Californians and the world to protect their environment.
Efforts to protect these trees include:
- national and state park designations,
- controlled burns to manage fire risk,
- reforestation projects, and
- climate research initiatives
...aimed at understanding and mitigating climate change impacts.
