The Giant Sequoia (Sequoiadendron giganteum) is an iconic conifer, known as the largest tree by volume on Earth. Native to California’s Sierra Nevada, it reaches up to 310 feet (95 m) tall and up to 35 feet (11 m) in diameter. Most individuals range between 250–275 feet in height and 15–20 feet in diameter at breast height. The bark, fibrous and furrowed, can be up to two feet thick, offering exceptional fire resistance.
