![]() The leaves are evergreen, awl-shaped, 3–6 mm ( 1⁄ 8– 1⁄ 4 in) long, and arranged spirally on the shoots. The sap contains tannic acid, which provides significant protection from fire damage. ![]() Giant sequoia bark is fibrous, furrowed, and may be 90 cm (3 ft) thick at the base of the columnar trunk. Giant sequoias are among the oldest living organisms on Earth, and are the verified third longest-lived tree species after the Great Basin bristlecone pine and alerce. The oldest known giant sequoia is 3,200–3,266 years old based on dendrochronology. The trunks of coast redwoods taper at lower heights than those of giant sequoias which have more columnar trunks that maintain larger diameters to greater heights. Between 20, it is claimed that specimens of coast redwood were found to have greater trunk diameters than all known giant sequoias - though this has not been independently verified or affirmed in any academic literature. The specimen known to have the greatest diameter at breast height is the General Grant tree at 8.8 m (28.9 ft). Trunk diameters of 17 m (56 ft) have been claimed via research figures taken out of context. Record trees have been measured at 94.8 m (311 ft) tall. They grow to an average height of 50–85 m (164–279 ft) with trunk diameters ranging from 6–8 m (20–26 ft). Giant sequoia specimens are the most massive individual trees in the world. Description Opened pollen cones Mature cones and seed Endlicher thus coined the name "Sequoia" as both a description of the tree's genus and an honor to the indigenous man he admired. He also realized that coincidentally the genus could be described in Latin as sequi (meaning to follow) because the number of seeds per cone in the newly classified genus aligned in mathematical sequence with the other four genera in the suborder. A linguist and botanist, Endlicher corresponded with experts in the Cherokee language including Sequoyah, whom he admired. Endlicher is actually responsible for the name. An etymological study published in 2012 concluded that Austrian Stephen L. The etymology of the genus name has been presumed-initially in The Yosemite Book by Josiah Whitney in 1868 -to be in honor of Sequoyah (1767–1843), who was the inventor of the Cherokee syllabary. The species is named in honor of the Cherokee Chief Sequoyah. The giant sequoia is a very popular ornamental tree in many parts of the world. ![]() The wood was unsuitable for construction and instead used for fence posts or match sticks. Wood from mature giant sequoias is fibrous and brittle trees would often shatter after they were felled. The oldest known giant sequoia is 3,200–3,266 years old. Giant sequoias are among the oldest living organisms on Earth. The specimen known to have the greatest diameter at breast height is the General Grant tree at 8.8 m (28.9 ft). Record trees have been measured at 94.8 m (311 ft) tall. 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). Prescribed burns to reduce available fuel load may be crucial for saving the species. Since its last assessment as an endangered species in 2011, it was estimated that another 13–19% of the population (or 9,761–13,637 mature trees) were destroyed during the Castle Fire of 2020 and the KNP Complex & Windy Fire in 2021, events attributed to fire suppression and drought. The giant sequoia is listed as an endangered species by the IUCN, with fewer than 80,000 trees remaining. They occur naturally only in groves on the western slopes of the Sierra Nevada mountain range of California. Giant sequoia specimens are the most massive trees on Earth. ![]() Sequoiadendron giganteum, also known as the giant sequoia, giant redwood or Sierra redwood is a coniferous tree, classified in the family Cupressaceae in the subfamily Sequoioideae.
