Coastal redwood trees, scientifically known as Sequoia sempervirens, are among the tallest trees in the world, reaching heights of over 350 feet. They are native to the coastal regions of northern California and southern Oregon. These trees thrive in the moist, foggy climate of the Pacific coast, which provides the necessary humidity for their growth. The bark of coastal redwoods is thick and fibrous, offering protection from pests and fire. They can live for over 2,000 years, making them some of the oldest living organisms on Earth. Coastal redwoods play a crucial role in their ecosystem, providing habitat for various wildlife species.
