Sequoiadendron Giganteum
''Sequoiadendron giganteum'' (also known as the giant sequoia, giant redwood, Sierra redwood or Wellingtonia) is a species of coniferous tree, classified in the family Cupressaceae in the subfamily Sequoioideae. Giant sequoia specimens are the largest trees on Earth. They are native to the groves on the western slopes of the Sierra Nevada (U.S.), Sierra Nevada mountain range of California but have been introduced, planted, and grown around the world. The giant sequoia is listed as an endangered species by the International Union for Conservation of Nature, IUCN with fewer than 80,000 remaining in its native California. The tree was introduced to the U.K. in 1853, and by now might have 500,000 trees growing there where it is more commonly known as Wellingtonia after the Duke of Wellington. The giant sequoia grow to an average height of 50–85 m (164–279 ft) with trunk diameters ranging from 6–8 m (20–26 ft). Record trees have been measured at 94.8 m (311&nbs ...
