It is an evergreen, long-lived, monoecious tree living 1,200–1,800 years or more.This species includes the tallest living trees on Earth, reaching up to 379 feet (115.5 m) in height (without the roots) and up to 29.2 feet (8.9 m) in diameter at breast height. These trees are also among the oldest living things on Earth. Before commercial logging and clearing began by the 1850s, this massive tree occurred naturally in an estimated 2,000,000 acres (810,000 ha)along much of coastal California (excluding southern California where rainfall is not sufficient) and the southwestern corner of coastal Oregon within the United States.
