Oregon Redwoods Vs California Redwoods: How Do They Compare?

With their towering heights and ancient age, redwood trees capture the imagination of nature lovers everywhere. Both Oregon and California are home to impressive groves of these giant trees, but are there differences between the two?

If you’re short on time, here’s a quick answer: While Oregon and California both host coastal redwoods, California has larger and more extensive redwood forests, including trees that are taller, older, and larger in volume. Oregon’s redwoods are limited to a small region along the southern coast.

In this approximately 3000 word guide, we’ll take an in-depth look at Oregon vs California redwoods, exploring everything from their natural ranges, typical sizes, oldest specimens, and best places to visit each type of redwood forest.

Natural Range and Habitats

California Redwood Range

The California Redwoods, scientifically known as Sequoia sempervirens, are mainly found along the coast of California. Their natural range stretches from southern Oregon to central California, covering an area of approximately 450 miles.

These majestic trees thrive in the foggy and temperate climate of the region, and their habitats include coastal areas and some inland valleys.

The California Redwoods are known for their towering height, with some reaching over 350 feet tall. They have a distinctive reddish-brown bark and their foliage consists of needle-like leaves that are evergreen, providing a year-round lush appearance to their habitats.

Oregon Redwood Range

The Oregon Redwoods, also known as the Douglas fir trees (Pseudotsuga menziesii), have a broader range compared to their Californian counterparts. They can be found throughout the Pacific Northwest, including Oregon, Washington, and parts of British Columbia.

Their habitats range from lowland forests to mountainous regions, and they can tolerate a wider range of climates compared to the California Redwoods. The Oregon Redwoods are characterized by their straight trunks, dense foliage, and cones that hang downward.

Climate Differences Between Regions

The climate plays a significant role in shaping the habitats of both the California and Oregon Redwoods. The coastal areas of California where the California Redwoods thrive have a maritime climate, characterized by cool summers and mild winters.

The presence of fog and moisture from the Pacific Ocean creates an ideal environment for these trees to grow.

On the other hand, the Oregon Redwoods are adapted to a more diverse climate. They can tolerate a wider range of temperatures and precipitation levels, allowing them to occupy a larger geographical area.

The Pacific Northwest experiences more rainfall compared to California, providing ample water supply for the Oregon Redwoods.

While both the California and Oregon Redwoods share some similarities in terms of appearance and ecological significance, their natural ranges and habitats differ due to variations in climate and geographical conditions.

Typical Tree Sizes


The height of redwood trees is one of the most awe-inspiring features that make them truly remarkable. Both Oregon and California redwoods can reach staggering heights, but there are slight differences between the two.

Oregon redwoods, also known as Coast Redwoods (Sequoia sempervirens), have been recorded to grow as tall as 379 feet (115.5 meters), making them the tallest trees on the planet. These giants can reach heights equivalent to a 35-story building!

The tallest known Oregon redwood, named Hyperion, stands at an astounding 379.7 feet (115.7 meters).

On the other hand, California redwoods, commonly referred to as Giant Sequoias (Sequoiadendron giganteum), are not as tall as their Oregon counterparts. They typically reach heights of 250-300 feet (76-91 meters).

However, what they lack in height, they make up for in other impressive characteristics.

Trunk Diameter

When it comes to trunk diameter, both Oregon and California redwoods boast remarkable girths that contribute to their grandeur. The trunk diameter of redwoods is a testament to their age and resilience.

Oregon redwoods have an average trunk diameter ranging from 8 to 20 feet (2.4 to 6 meters). Some exceptionally wide trees have been measured to have diameters exceeding 26 feet (7.9 meters). These massive trunks provide stability and support for the towering heights of the trees.

Similarly, California redwoods have impressive trunk diameters as well. Although not as wide as their Oregon counterparts, they still reach sizes that can leave one in awe. The average trunk diameter of a California redwood ranges from 20 to 26 feet (6 to 8 meters).

Some of the largest known trees have trunks measuring over 30 feet (9.1 meters) in diameter!


Redwood trees are not only known for their height and trunk diameter but also for their incredible biomass. Biomass refers to the total amount of living matter in an organism, and redwoods are among the most massive living beings on Earth.

Oregon redwoods have an estimated average biomass of 1,200 to 1,500 metric tons per hectare (10,000 square meters). This means that in just one hectare of forest, there can be over a thousand metric tons of living redwood matter!

The dense forests of Oregon are a testament to the sheer size and abundance of these magnificent trees.

California redwoods, although not as massive as their Oregon counterparts, still have an impressive biomass. The average biomass of a California redwood forest is estimated to be around 500 to 600 metric tons per hectare.

While this is lower than the biomass of Oregon redwood forests, it is still an astonishing amount of living matter.

It is important to note that these figures are estimates and can vary depending on various factors such as age, location, and environmental conditions.

Oldest Specimens

California’s Oldest Redwoods

When it comes to the oldest redwood trees, California has some truly remarkable specimens. The Methuselah Tree, located in the White Mountains of California, is estimated to be around 4,800 years old, making it one of the oldest living organisms on Earth.

This ancient tree has survived countless wildfires, harsh weather conditions, and even human interference. Its ability to withstand the test of time is truly awe-inspiring.

Another notable old-growth redwood in California is the General Sherman Tree, located in Sequoia National Park. While not as old as the Methuselah Tree, it holds the title for being the largest tree in the world by volume.

Standing at a height of 275 feet and with a diameter of 25 feet, this magnificent tree is estimated to be around 2,200 years old. It serves as a testament to the resilience and longevity of California’s redwoods.

Oregon’s Oldest Redwoods

In Oregon, the redwood trees may not reach the same age as their Californian counterparts, but they still boast impressive lifespans. The oldest known redwood in Oregon is the Klootchy Creek Giant, which was estimated to be around 750 years old before it fell in a storm in 2007.

This tree was a beloved landmark and a symbol of Oregon’s natural beauty.

While the Klootchy Creek Giant may no longer be standing, there are still many ancient redwoods in Oregon’s forests. Some of the oldest trees in the state can be found in the Redwood National and State Parks, where visitors can witness the majesty of these ancient giants.

Why California Trees Live Longer

One might wonder why California’s redwoods tend to live longer than those in Oregon. One possible explanation is the difference in climate and environmental conditions. California’s redwoods are often exposed to longer periods of drought, which can lead to slower growth rates but also promote their longevity.

Additionally, California’s redwoods have evolved to withstand the frequent wildfires that occur in the state, developing thick bark and other adaptations that allow them to survive and thrive.

It’s important to note that while California’s redwoods may have longer lifespans on average, there are still many factors that can influence the lifespan of individual trees, including genetics, disease, and human interaction. Each redwood tree has its own unique story and journey through time.
