Sequoiadendron giganteum (Giant sequoia) - Plant
Giant sequoias are the world's largest single trees and largest living thing by volume. Giant sequoias grow to an average height of 50?85 m (164?279 ft) and 6?8 m (20?26 ft) in diameter. Record trees have been measured to be 94.8 m (311 ft) in height. Claims of 17 m (56 ft) diameter have been touted by taking an author's writing out of context, but the widest known at chest height is closer to 8.2 m (27 ft). Between 2014 and 2016, specimens of coast redwood were found to have larger trunk diameters than all known giant sequoias. The oldest known giant sequoia based on ring count is 3,500 years old. Giant Sequoias are among the oldest living things on Earth. Sequoia bark is fibrous, furrowed, and may be 90 cm (3.0 ft) thick at the base of the columnar trunk. It provides significant fire protection for the trees.
