The giant redwood tree, scientifically known as Sequoiadendron giganteum, is one of the largest tree species in the world. These trees can grow over 300 feet tall and live for more than 3,000 years. They are primarily found in the Sierra Nevada mountain range in California, thriving in specific climates that provide ample moisture. Giant redwoods have thick, fire-resistant bark that helps protect them from wildfires. Their massive trunks can reach up to 30 feet in diameter, making them a popular attraction in national parks like Yosemite and Sequoia National Park. These trees play a crucial role in their ecosystem, providing habitat for various wildlife.
