California is home to a range of forest types that make it a unique and exciting environment. Not only can visitors find a temperate forest and coniferous forest, but it is also possible to explore a temperate rainforest in the United States.

Plus, California is home to some of the oldest and rarest trees on the planet. Both the redwood and giant sequoia are found within California.

Types of Forests in California

Within California, there are several opportunities to see wildlife and forested area. There are many types of tree species found in this diverse state. Within California, visitors can expect to see primarily temperate forests, but it is also possible to see pockets of temperate rainforest and coniferous forests in the southern part of the state.

Given the right growing conditions, this state is home to some of the oldest and largest trees in the world. Both the ancient redwood forests and giant sequoias can be found in California.  

Temperate Forest

The temperate forest makes up the majority of the forest in California. This type of forest can contain both deciduous and coniferous trees. Any forest that is located between the tropic area and boreal forest zone is considered temperate.

California, due to its location, is mostly temperate. Usually, in a temperate forest, the average temperature hovers around 50 degrees.  

Sierra Nevada Area

The Sierra Nevada area is home to some of the most beautiful forests in California. Scientists have estimated that 50% of California’s 7,000 species of plants live in the Sierra Nevada area. This range also has more than 200 rare species.

The majority of the rare or threatened species live in the southern range of the Sierra Nevada. In this forest, expect to find mostly coniferous species of trees. A coniferous tree has needles instead of leaves which helps to keep the tree hydrated and well protected through drought and harsh weather conditions.  

Several plants and animals live in the Sierra Nevada forest. The most popular trees found in this area include North Jeffrey Pine, Sierran Montane, Sierra Yellow Pine, Junipers, and Yellow Pine shrubs. This area is also home to several animals, with 60% of California’s animals calling the Sierra Nevada range home.

The Kern salamander, Yosemite toad, long-eared chipmunk, Yellow-eared pocket-mouse, and golden trout can be found in this forested area. Large animals such as the grizzly bear, black bear, and wolverine can also be found. Birds include raptors such as owls, hawks, and eagles.  

Giant Sequoias

One of the most popular forest types in California is the massive Giant Sequoia groves. Many of these sequoia trees live in just three groves in Yosemite National Park. The trees are closer to the southern entrance of the park near Mariposa Grove.

There are also two smaller groves of sequoia trees located near Tuolumne and Merced Grove. This type of tree is largely endangered, and there are only 75 groves of Giant Sequoias left on the earth. These groves are mostly in the western Sierra Nevada and are only a stretch of 15 miles by 250 miles long.  

The Giant Sequoia is an interesting and fascinating species of tree that is the longest living organism on the earth. These trees can live to be well over 3,000 years old. The giant sequoia tree is an essential part of many California habitats and is a vital contributor to the delicate environment in California’s forests.  

Redwood Forest

The famous redwood forest is actually part of a temperate rainforest that exists in California. Although many people assume that a rainforest must also be tropical, an area is classified as a rainforest based on the amount of rain it receives.

A rainforest must receive at least 60 inches of rain per year, and the redwood forest in California receives well over 100 inches of rain each year.  

The giant trees are located on California’s northern coast in Humboldt Redwoods State Park. This area has a 31-mile stretch of a redwood grove that features the famous “Avenue of Giants.” Many of the trees in the redwood forest are ancient old-growth trees that have lived for hundreds, if not thousands of years.

Redwood trees are particularly long-lived. The oldest tree in California is a coastal redwood which is over 2,500 years old.  

Coniferous Forest

Plenty of conifers make up the forests in the southern regions of California. These trees maintain their leaves year-round and often have long needles rather than broad leaves. Coniferous trees tend to be more durable and weather-resistant, making them less prone to drought or harsh weather.

Common trees found in the southern part of the state include ghost pines, Coulter pines, and Douglas fir trees.  


California is a big area to explore with plenty of natural wildlife and forested area. There are countless pockets of forested land in California, so understanding the many forest types in California can be tricky.

To help you make sense of what California has to offer, we have put together a list of some of the most commonly asked questions related to California’s forests so you can better understand what this wonderful state has to offer.

How much of California is forest?

About 32% of California is covered by forest. Compared to other states, this is about the average amount of forested land. California is dominated by temperate forest but also has pockets of temperate rainforest and coniferous forest.

What is the oldest tree in California?

The oldest tree in California is the giant sequoia tree, or Sequoiadendron giganteum, which is also the oldest organism on the planet. Some trees in California are estimated to be over 3,200 years of age. The tree bark alone on these giant trees has been over three feet thick in some areas.  

What is the tallest tree species in California?

The tallest tree in California is a redwood tree. These large trees can be found along the coast and are known to grow to towering heights. The largest tree is nicknamed “Hyperion,” and this tree is 379 feet tall.

Scientists have continually studied and researched the trees throughout this area to monitor their growth and ensure they stay healthy and protected. The Hyperion tree, though located in a secret location, remains protected within Redwood National Park.  

How many National Parks are located in California?

California is home to a wide range of environments, and it follows that there are many national parks in this state. In total, there are 9 National Parks found within California. These National Parks include:

  • Joshua Tree National Park
  • Yosemite National Park
  • Redwood National Park
  • Lassen Volcanic National Park
  • Point Reyes National Seashore
  • Channel Islands National Park
  • Death Valley National Park
  • Pinnacles National Park

Each National Park is able to offer a completely different experience with a range of diversity that can be found only in California.
