Sequoiadendron giganteum is the sole living species in the genus Sequoiadendron, and one of three species of coniferous trees known as redwoods, classified in the family Cupressaceae in the subfamily Sequoioideae, together with Sequoia sempervirens and Metasequoia glyptostroboides. Giant sequoia specimens are the most massive trees on Earth. The common use of the name sequoia usually refers to Sequoiadendron giganteum, which occurs naturally only in groves on the western slopes of the Sierra Nevada mountain range of California.
Sequoia National Park is an American national park in the southern Sierra Nevada east of Visalia, California. The park was established on September 25, 1890, and today protects 404,064 acres of forested mountainous terrain. Encompassing a vertical relief of nearly 13,000 feet (4,000 m), the park contains the highest point in the contiguous United States, Mount Whitney, at 14,505 feet (4,421 m) above sea level. The park is south of, and contiguous with, Kings Canyon National Park; both parks are administered by the National Park Service together as the Sequoia and Kings Canyon National Parks. UNESCO designated the areas as Sequoia-Kings Canyon Biosphere Reserve in 1976.
The Giant Sequoia National Monument is a 328,000-acre (512 sq mi) U.S. National Monument located in the southern Sierra Nevada in eastern central California. It is administered by the U.S. Forest Service as part of the Sequoia National Forest and includes 38 of the 39 Giant Sequoia 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 km2).
General Grant Grove, a section of the greater Kings Canyon National Park, was established by the U.S. Congress in 1890 and is located in Fresno County, California. The primary attraction of General Grant Grove is the giant sequoia trees that populate the grove. General Grant Grove's most well-known tree is called General Grant, which is 267 ft (81 m) tall and the third-largest known tree in the world. The General Grant tree is over 1,500 years old and is known as the United States' national Christmas tree. General Grant Grove consists of 154 acres (0.62 km2) and is geographically isolated from the rest of Kings Canyon National Park.
Sequoia National Forest is located in the southern Sierra Nevada mountains of California. The U.S. National Forest is named for the majestic Giant Sequoia trees which populate 38 distinct groves within the boundaries of the forest.
Redwood Mountain Grove is the largest grove of giant sequoia trees on earth. It is located in Kings Canyon National Park and Giant Sequoia National Monument on the western slope of California's Sierra Nevada. The grove contains the world's tallest giant sequoia. The Hart Tree and Roosevelt Tree grow in the grove and are two of the 25 largest trees by volume in the world. The largest tree is the General Sherman Tree in the Giant Forest grove to the southeast.
The Giant Forest, famed for its giant sequoia trees, is within the United States' Sequoia National Park. This montane forest, situated at over 6,000 ft (1,800 m) above mean sea level in the western Sierra Nevada of California, covers an area of 1,880 acres (7.6 km2). The Giant Forest is the most accessible of all giant sequoia groves, as it has over 40 mi (64 km) of hiking trails.
The McNally Fire was a massive wildfire in the Sequoia National Forest which burned 150,696 acres (609.8 km2) in July and August 2002, and the largest wildfire of the 2002 California wildfire season. The fire burned from July 21 to August 29, 2002, through the Sequoia and Inyo National Forest, as well as 5% of Giant Sequoia National Monument. It destroyed 14 structures and cost an estimated $45.7 million to put out. The blaze was started due to the "careless use of fire" near the Roads End Resort in Kern Canyon, and spread east through the canyon and threatened the communities of Johnsondale and Ponderosa. It burned within one mile (1.6 km) of the Packsaddle Grove of giant sequoias.
Converse Basin Grove is a grove of giant sequoia trees in the Giant Sequoia National Monument in the Sierra Nevada, in Fresno County, California, 5 miles (8 km) north of General Grant Grove, just outside Kings Canyon National Park. Once home to the second-largest population of giant sequoias in the world, covering 4,600 acres (19 km2) acres, the grove was extensively logged by the Sanger Lumber Company at the turn of the 20th century. The clearcutting of 8,000 giant sequoias, many of which were over 2,000 years old, resulted in the destruction of the old-growth forest ecosystem.
Alder Creek Grove is a giant sequoia grove located both on private land and within the Giant Sequoia National Monument in the western Sierra Nevada of California. The grove is spread out over approximately 785 acres (318 ha) of land and contains 483 giant sequoias that are at least 25.5 feet in diameter, including the Stagg Tree, the 5th largest tree in the world and one of the oldest known living giant sequoias. Though on private land, the Rouch family made part of their land accessible to the public.
Mountain Home Grove is a grove of giant sequoia trees located in the southern part of the Sierra Nevada Mountains of California, and includes some of the largest trees in the world.
The Monarch Wilderness is a federally designated wilderness area located 70 miles east of Fresno, California, in the Sierra Nevada mountain range. It encompasses 44,896 acres (181.69 km2) within both the Sequoia National Forest and the Sierra National Forest and is managed by the United States Forest Service. Elevations range from 950 feet (290 m) to 11,081 ft (3,377 m).
Packsaddle Grove is a medium-sized sequoia grove on Giant Sequoia National Monument located in the South Creek of the Kern River watershed. It is a fairly wet grove as it straddles Packsaddle Creek and its tributaries.
The Belknap Complex, sometimes referred to as Belknap Grove, is a complex of three giant sequoia groves located in the Tule River watershed of Giant Sequoia National Monument, just south of Camp Nelson, California. It is formed from the larger McIntyre Grove and Wheel Meadow Grove, and the smaller Carr Wilson Grove. The grove is home to a rich collection of old-growth giant sequoias spread out over 4,666 acres (18.88 km2). The grove is fairly easy to reach by car given its close proximity to Highway 190. Forest Trail 31E30 meanders through the heart of the complex.
The Boole Tree is a giant sequoia in the Giant Sequoia National Monument, Fresno County, California. The Boole Tree is the eighth tallest sequoia in the world and is the largest in terms of base circumference at 112 feet. It is estimated to be more than 2,000 years old. The tree's stature is accentuated by its isolation above the Kings River where it towers over the rest of the forest.
Ishi Giant is a giant sequoia in California, United States. It is located in Kennedy Grove, which is part of a group of eight closely spaced giant sequoia groves situated in Sequoia National Forest in the Sierra Nevada in eastern central California. It was the 14th largest giant sequoia in the world before it atrophied during the Rough Fire in 2015.
The General Noble Tree was a Giant Sequoia tree formerly within the Converse Basin Grove, with its site located in Giant Sequoia National Monument of the Sierra Nevada, in Fresno County, California. It was one of the largest trees on the planet during that time, before it was felled in 1892 to create an exhibit for the 1893 World's Columbian Exposition held in Chicago.
The protected areas of the Sierra Nevada, a major mountain range located in the U.S. states of California and Nevada, are numerous and highly diverse. Like the mountain range itself, these areas span hundreds of miles along the length of the range, and over 14,000 feet of elevation from the lowest foothills to the summit of Mount Whitney.
