The tallest tree in the world is the Mendocino Redwood, which is a coast redwood (Sequoia sempervirens). It is 367.5 feet tall (112 meters), and it stands at the Montgomery Woods State Reserve near Ukiah, California. Even though the General Sherman tree is the largest tree on Earth, there are plenty of trees that are taller than it. The coast redwoods, which grow near the Pacific Coast in California and Oregon, commonly grow to heights of over 300 feet (91 meters)! This species grows taller than the giant sequoia, but they are more slender and not as massive. The Mendocino Redwood is estimated to be ten centuries old, and the height was measured using a laser in 1998; at this time it had a diameter of 10 feet, 4 inches (3.14 meters). - Millet (Drill ANWR)
