The Sequoia trees are the oldest living things in the world. They grew in large forests millions of years ago, in the age of dinosaurs. During the Ice Age many kinds of Sequoias disappeared and only two kinds left on our planet. One of them, the giant Sequoia, can be found only in the north of California.
The tree was named after Sequoyah, an American Indian, who invented a written alphabet for his tribe.
No one knows how long a Sequoia can live. Many trees in Sequoia National Park, in California, are more than 3,000 years old. Now there is a law that protected Sequoias from being cut. But before it was passed one of the oldest and largest of them was chopped down. The growth ring at the center of this giant Sequoia dated back to 1305 BC. It means that it was more than a thousand years old at the time of the birth of Christ!
The General Sherman tree is one of the biggest Sequoias in the world. It is 83.8 metres high, and the diameter of its trunk is 31.4 metres.
