红杉, or the giant sequoia, is a type of tree native to the western United States, particularly in the Sierra Nevada mountain range. Known for their impressive height and longevity, these trees can grow over 300 feet tall and live for more than 3,000 years. They thrive in specific climates and are often found in protected national parks. The wood of the 红杉 is highly valued for its resistance to decay and its beautiful grain. This has made it a popular choice for construction and furniture. However, conservation efforts are crucial to protect these magnificent trees from threats such as climate change and logging.
