Redwood trees are among the tallest trees in the world, reaching heights of over 350 feet. They are primarily found in the coastal regions of northern California and southern Oregon. These trees can live for more than 2,000 years, making them some of the oldest living organisms on Earth. Their thick bark helps protect them from fire and pests. There are two main species of redwoods: the coast redwood and the giant sequoia. Coast redwoods thrive in moist, foggy environments, while giant sequoias are typically found in the Sierra Nevada mountains. Both species are valued for their impressive size and ecological importance.
