The giant sequoia is the world’s most massive tree, and arguably the largest living organism on Earth. With a height of 286 feet (87 m) or more, a circumference of 113 feet (34 m) or more, an estimated bole volume of up to 52,500 cubic feet (1,487 m3), and an estimated age of 1800–2700 years, the giant sequoia is among the tallest, widest and longest-lived of all organisms on Earth.
Giant sequoias grow in California forests. Because most of the neighboring trees are also quite large, it can be difficult to appreciate the size of an individual giant sequoia. (From Wikipedia, the free encyclopedia)
