At 112.83 metres or 370 feet tall in 2004 and still growing, Stratosphere Giant, of the species Sequoia sempervirens, located in the Humboldt Redwoods State Park, California, USA, was considered the tallest tree until September 8th, 2006 . The exact locations of the tallest trees have not been disclosed for fear that human traffic would upset the ecosystem. Hyperion, discovered by researcher Chris Atkins and amateur naturalist Michael Taylor in a remote area of the Redwood National Forest purchased during the Carter Administration, is the name of the redwood tree in Northern California that has now been confirmed to measure 115.5 m (379.1 feet), which ranks it as the world's tallest living thing at this moment. The abundant moisture and moderate temperatures of coastal northern California and extreme southern Oregon allow the redwood to flourish but annual precipitation seems less important than the frequent summer fog. The warm, moist marine air over the cold surface of the Pacific creates fog almost daily in summer in the forest. The fog decreases the trees' loss of water through evaporation and transpiration and adds moisture to the soil. So the coast redwood is generally restricted to this coastal fog belt.
