General Sherman is a giant sequoia (Sequoiadendron giganteum) tree located at an elevation of 2,109 m (6,919 ft) above sea level in the Giant Forest of Sequoia National Park in Tulare County, in the U.S. state of California. By volume, it is the largest known living single-stem tree on Earth.[1] It is estimated to be around 2,200 to 2,700 years old.

History

The General Sherman Tree was named after the American Civil War general William Tecumseh Sherman. The official story, which may be apocryphal, claims the tree was named in 1879 by naturalist James Wolverton, who had served as a lieutenant in the 9th Indiana Cavalry under Sherman.[2]

Seven years later, in 1886, the land came under the control of the Kaweah Colony, a utopian socialist community whose economy was based on logging. Noting the pivotal role that Sherman had played in the Indian Wars and his forced relocation of native American tribes, they renamed the tree in honor of Karl Marx.[3] However, the community was disbanded in 1892, primarily as a result of the establishment of Sequoia National Park, and the tree reverted to its previous name.

In 1931, following comparisons with the nearby General Grant tree, General Sherman was identified as the largest tree in the world. One result of this process was that wood volume became widely accepted as the standard for establishing and comparing the size of different trees.[1][4]

In January 2006, the largest branch on the tree (seen most commonly, in older photos, as an "L" or golf-club shape, protruding from about a quarter of the way down the trunk) broke off. There were no witnesses to the incident, and the branch – larger than most tree trunks; diameter over 2 m (6.6 ft) and length over 30 m (98 ft) – smashed part of the perimeter fence and cratered the pavement of the surrounding walkway. The breakage is not believed to be indicative of any abnormalities in the tree's health, and may even be a natural defense mechanism against adverse weather conditions.[5]

Six firefighters clad in yellow gear place sheets of silver foil around the tree's base, slightly above the height of their heads.

On September 16, 2021, the tree was threatened by the KNP Complex Fire in Sequoia National Park. Park and firefighting personnel wrapped the tree's base in a protective foil usually used on structures in case the wildfire approached the General Sherman Tree—which, in the end, was left unharmed.[6][7]

Dimensions

While it is the largest tree known, the General Sherman Tree is neither the tallest known living tree on Earth (that distinction belongs to the Hyperion tree, a Coast redwood),[8] nor is it the widest (both the largest cypress and largest baobab have a greater diameter), nor is it the oldest known living tree on Earth (that distinction belongs to a Great Basin bristlecone pine).[9] With a height of 83.8 meters (275 ft), a diameter of 7.7 m (25 ft), an estimated bole volume of 1,487 m3 (52,513 cu ft), and an estimated age of 2,300–2,700 years,[10][11][12] it is nevertheless among the tallest, widest, and longest-lived of all trees on the planet.

While General Sherman is the largest currently living tree, it is not the largest historically-recorded tree. The Lindsey Creek tree, with more than 90,000 cubic feet (2,500 cubic meters)[13] almost twice the volume of General Sherman, was reported felled by a storm in 1905.[14][15] Another larger tree, the Crannell Creek Giant, a coast redwood (Sequoia sempervirens) cut down in the mid-1940s near Trinidad, California, is estimated to have been 15–25% larger than the General Sherman Tree by volume. Similarly, the Mother of the Forest, another giant sequoia, may have historically been larger than General Sherman. Two other historical and exceedingly enormous giant sequoias, the Discovery Tree with a near-30m circumference,[16] and especially the long-fallen "Father of the Forest" from Calaveras Grove, reportedly a whopping 435ft high and 110ft in circumference,[17] are widely considered to have once been larger than General Sherman. In addition, the Burnt Monarch from Big Stump Grove had a much larger base than General Sherman and could have easily been larger as well [18].
