Redwoods (scientific name: Sequoia sempervirens) are the tallest trees in the world, they easily reach heights of 300 feet (91 meters) and even more. They are not the tallest only, also evergreen and very long-lived: their life span is more than 1000 years, and some have been documented at even more than 2,000 years old. They can grow up to 29.2 feet (8.9 m) in diameter at breast height / dbh. Redwoods live in California, United States; and before commercial logging and clearing began by the 1850s, this massive tree occurred naturally in an estimated 2,100,000 acres (8,500 km2) along much of coastal California (excluding southern California where rainfall is not sufficient) and the southwestern corner of coastal Oregon within the United States. Now, unfortunately, an estimated 70% or more of ancient old-growth redwood trees have been displaced by environmental changes or cut down.
Among the redwoods, a tree named Hyperion dwarfs them all. The tree was discovered on August 25, 2006, by naturalists Chris Atkins and Michael Taylor, and is 379.7 feet (115.7 meters) tall.
The tree is estimated to contain 530 m3 (18,600 cu ft) of wood and to be roughly 700–800 years old. Researchers stated that woodpecker damage at the top may have prevented the tree from growing taller. According to Michael Taylor, “It’s possible it could’ve topped out at 380 feet (116 meters)”.
