Redwoods are some of the tallest trees in the world, primarily found in the coastal regions of California and Oregon. They belong to the species Sequoiadendron giganteum and Sequoia sempervirens, with the latter being the tallest tree species, reaching heights of over 350 feet. These trees can live for more than 2,000 years, making them some of the oldest living organisms on Earth. Redwoods thrive in moist, foggy environments, which provide the necessary humidity for their growth. Their thick bark is resistant to fire and pests, allowing them to survive in various conditions. These majestic trees play a crucial role in their ecosystems, providing habitat for numerous species and helping to regulate the climate.
