UKIAH, Calif. -- A towering redwood surrounded by other giant trees in Northern California has been identified as the world's tallest living thing.

Named the Mendocino Tree, the 600- to 800-year-old redwood stands 367 1/2 feet tall.

Measurements of the tree in Montgomery Woods State Reserve were conducted in mid-March by a special team led by Steve Sillet, a Humboldt State University professor. The results were videotaped and verified by the Guinness Book of World Records.

The older and more massive Tall Tree in Redwood National Park in Del Norte County held the previous title. It once stood nearly 368 feet tall but lost 10 feet during a recent winter storm.

Discovery of the Mendocino Tree, about 12 miles west of Ukiah, was kept quiet by park rangers and environmentalists to keep curiosity-seekers from trampling the fragile site around it.

There will be no official marker identifying the tree. Despite its grandeur, the tree is barely distinguishable from an 80-acre cluster of two dozen or more surrounding trees standing 350 feet or taller.

At 1,300 acres, Montgomery Woods is the least visited of Mendocino County's redwood preserves. Some local residents determined to keep it that way have started tearing down roadside state park signs in hopes of keeping the reserve to themselves.
