The largest living tree on Earth is still adding the volume of a small tree every year

General Sherman, a giant sequoia in California's Sequoia National Park, has a trunk volume of roughly 1,487 cubic metres — more than any other known living tree, despite not being the tallest or the oldest. Believed to have first sprouted over 2,000 years ago, it's still growing: each year it adds enough new wood to build a good-sized ordinary tree from scratch. Giant sequoias reach this scale partly because they can resist fire, rot and insects for millennia.
