<p>These trees grow only in 75 groups across 35,600 acres in California, near the Sierra Nevada mountains. These groups were formed as a protection from logging. The most famous area with sequoia trees is Sequoia National Park. The park was found as a second national park after the Yellowstone National Park in 1980. The Sequoia National Park is managed with Kings Canyon National Park. Both parks are together called Sequoia and Kings Canyon National Parks. Several trees in Sequoia National Park have even been named, for example General Grant, the Grizzly Giant or General Sherman.</p>
