Sequoia trees are some of the tallest and oldest trees in the world, known for their impressive height and massive trunks. These giant trees can grow over 300 feet tall and live for thousands of years. They are primarily found in the Sierra Nevada mountains of California, where they thrive in the cool, moist climate. The bark of sequoia trees is thick and spongy, which helps protect them from fire and pests. These trees play a vital role in their ecosystem, providing habitat for various wildlife and helping to maintain the health of the forest. Their grandeur attracts many visitors to national parks like Yosemite and Sequoia National Park.
