The largest living tree in the world is a giant sequoia named General Sherman (Sequoiadendron giganteum) located in Sequoia National Park in the Sierra Nevada, California, USA. The General Sherman Tree, the largest tree in the world, grows in the redwood groves of the National Park's Giant Forest. The world's largest tree (by volume), General Sherman, is facing a major challenge as wildfires threaten to spread to giant sequoia forests and Kings Canyon National Park (KNP). Giant Forest (named for the size of the giant tree) in Sequoia National Park, California; General Sherman is the largest known solitary tree in the world. The Giant Forest Reserve is home to some of the largest specimens of giant sequoias in the world, including a man named General Sherman that scientists believe is the largest single-trunk tree on Earth. This giant tree and many others grow in various giant redwood forests throughout California. The fires threaten the giant forest, a grove of about 2,000 redwoods, including five of the largest trees on Earth, some up to 3,000 years old, and five of the largest trees on Earth, some up to 3,000 years old. On Earth, some are as long as 3000 years. Two California fires -- one dubbed the "Colonial Fire" and the other "Paradise" -- are burning in Sequoia National Park in the Sierra Nevadas, home to some of the largest trees in the world. The Sierra Nevada is home to one of the largest trees in the world. The U.S. National Park Service closed Sequoia National Park on Tuesday after wildfires near Sequoia National Park threatened it. The world's largest trees, the California redwoods, and Kings Canyon National Parks were unaffected by wildfires Saturday, according to the Los Angeles Times. There are now concerns that the fires at the KNP complex could soon spread to the vast forest where General Sherman and many other giant sequoias (Sequoiadendron giganteum), also known as giant sequoias or Sierra sequoias, grow. Wildfires in California are forcing firefighters to wrap huge redwoods in fireproof blankets, including General Sherman, a 275-foot-tall specimen believed to be the world's largest tree by volume. The flames are getting closer and closer to the world's largest tree and other giant sequoias as man-made climate change exacerbates California's fearsome fire season. Far, far away, a colossal giant sequoia known as General Sherman has been spared the ongoing fires thanks to the efforts of California firefighters who wrapped the bases of the trees in aluminum blankets and cleared them of vegetation. General Sherman is considered to be the world's largest single tree by volume - it measures 1,487 cubic meters according to the US National Park Service - and has a circumference of 31 meters at the base of the trees.
