The coast redwood, scientifically known as Sequoia sempervirens, is a tall tree native to the coastal regions of northern California and southern Oregon. These trees can grow over 350 feet high, making them the tallest living trees on Earth. They thrive in moist, foggy environments and can live for more than 2,000 years. Coast redwoods have thick, reddish-brown bark that helps protect them from pests and fire. Their leaves are needle-like and can be flat or slightly curved. These trees play a crucial role in their ecosystem, providing habitat for various wildlife and contributing to carbon storage in the atmosphere.
