They are owned collectively by the American people through the federal government and managed by the United States Forest Service, a division of the United States Department of Agriculture.

It is administered by the U.S. Forest Service as part of the Sequoia National Forest and includes 38 of the 39 Giant Sequoia (Sequoiadendron giganteum) groves that are located in the Sequoia National Forest, about half of the sequoia groves currently in existence, including one of the ten largest Giant Sequoias, the Boole Tree, which is 269 feet (82 m) high with a base circumference of 112 feet (34 m). The forest covers 824 square miles (2,130 km).
