The term "Giant Tree" often refers to exceptionally large trees, such as the General Sherman Tree, which is a sequoia located in California. These trees can reach heights of over 300 feet and have trunks that can measure more than 30 feet in diameter. They are known for their impressive size and longevity, with some living for thousands of years. Giant trees play a crucial role in their ecosystems, providing habitat for various wildlife and contributing to carbon storage. They are often found in protected areas, such as national parks, to preserve their unique characteristics and the biodiversity surrounding them.
