The sequoia is a type of tree known for its impressive height and longevity. There are two main species: the giant sequoia and the coast redwood. Giant sequoias can grow over 300 feet tall and live for more than 3,000 years, making them some of the oldest living trees on Earth. These trees thrive in specific climates, primarily found in the western United States. They prefer well-drained soil and are often located in national parks, such as Sequoia National Park and Yosemite National Park. Sequoias play a vital role in their ecosystems, providing habitat for various wildlife.
