The coast redwood is the tallest tree species in the world, with a measured living specimen over 115 metres high.
Known scientifically as Sequoia sempervirens, the coast redwood grows naturally in a narrow, moist belt along the Pacific coast of northern California and southern Oregon. The famous tree Hyperion was measured at about 115.9 metres and is generally recognized as the tallest known living tree. Its exact location is restricted to reduce visitor damage.
Coast redwoods are often confused with giant sequoias. Giant sequoias have greater trunk volume and are generally more massive, but coast redwoods grow taller. Redwoods can also regenerate after fire or cutting by producing sprouts from roots and stumps. Their thick, tannin-rich bark helps protect mature trees from many fires and insects.
