Sequoia trees are among the tallest and oldest trees in the world, known for their impressive height and massive trunks. They can grow over 300 feet tall and live for more than 3,000 years. These trees are primarily found in the western United States, particularly in California within the Sierra Nevada mountain range. There are three main species of sequoias: the Giant Sequoia, the Coast Redwood, and the Dawn Redwood. Giant Sequoias are the largest by volume, while Coast Redwoods are the tallest. Sequoias thrive in moist, well-drained soil and are adapted to survive wildfires, which help their seeds to germinate.
