Coastal redwoods, scientifically known as Sequoia sempervirens, are the tallest trees in the world, reaching heights of over 350 feet. They primarily grow along the California coast, thriving in the moist, foggy climate. These trees can live for more than 2,000 years, making them some of the oldest living organisms on Earth. The bark of coastal redwoods is thick and fibrous, providing protection from pests and fire. Their unique ecosystem supports diverse wildlife, including the endangered marbled murrelet and the Northern spotted owl. Coastal redwoods play a crucial role in carbon sequestration, helping to mitigate climate change.
