The General Sherman Tree
National Park Service/Rick Cain
The General Sherman Tree in Sequoia National Park is the largest (by volume) tree in the world.
Computing the volume of a standing tree is the practical equivalent of calculating the volume of an irregular cone. For purposes of volume comparison, only the trunk of a giant sequoia is measured, including the restored volume of basal fire scars. Using these accepted standards and actual field measurements taken in 1975, the volume of the Sherman Tree was calculated to be slightly over 52,500 cubic feet (1,486.6 cubic meters).

Did You Know?
Sequoias get so large because they grow fast over a long lifetime. They live so long because they are resistant to many insects and diseases, and because they can survive most fires. Sequoias do have a weakness — a shallow root system. The main cause of death among mature sequoias is toppling.
