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. Their thick, fire-resistant bark helps protect them from wildfires, a common occurrence in their natural habitat. Giant sequoias thrive in well-drained, moist soils and are typically found in groves. They play a crucial role in their ecosystem, providing habitat for various wildlife species. Conservation efforts are in place to protect these magnificent trees from threats such as climate change and logging.
