Sequoiadendron giganteum, commonly known as the giant sequoia, is a species of tree native to the western slopes of the Sierra Nevada mountains in California. These trees are among the largest and oldest living organisms on Earth, with some reaching heights of over 300 feet and ages exceeding 3,000 years. Giant sequoias thrive in specific conditions, preferring well-drained soils and a climate with ample rainfall. Their thick bark provides protection from fire and pests, allowing them to survive in their natural habitat. These majestic trees play a crucial role in their ecosystem, supporting various wildlife and contributing to carbon storage.
