Sequoiadendron is a genus of evergreen trees, with two species, only one of which survives to the present: [1]
Sequoiadendron fossil pollen and macrofossils may have been found as early as the Cretaceous [5] and throughout the Northern Hemisphere, [6] including locations in western Georgia in the Caucasus region. [7]
Sequoia, Sequoya or Sequoyah may refer to:
Sequoiadendron giganteum, also known as the giant sequoia, giant redwood or Sierra redwood is a coniferous tree, classified in the family Cupressaceae in the subfamily Sequoioideae. Giant sequoia specimens are the most massive trees on Earth. They occur naturally only in groves on the western slopes of the Sierra Nevada mountain range of California.
Metasequoia, or dawn redwood, is a genus of fast-growing deciduous trees, one of three species of conifers known as redwoods. The living species Metasequoia glyptostroboides is native to Lichuan county in Hubei province, China. Although the shortest of the redwoods, it grows to at least 165 feet in height. Local villagers refer to the original tree from which most others derive as Shuǐshān (水杉), or "water fir", which is part of a local shrine. Since its rediscovery in 1944, the dawn redwood has become a popular ornamental, with examples found in various parks in a variety of countries.
Cupressaceae is a conifer family, the cypress, with worldwide distribution. The family includes 27–30 genera, which include the junipers and redwoods, with about 130–140 species in total. They are monoecious, subdioecious or (rarely) dioecious trees and shrubs up to 116 m (381 ft) tall. The bark of mature trees is commonly orange- to red-brown and of stringy texture, often flaking or peeling in vertical strips, but smooth, scaly or hard and square-cracked in some species.
Gunnera is the sole genus of herbaceous flowering plants in the family Gunneraceae, which contains 63 species. Some species in this genus, namely those in the subgenus Panke, have extremely large leaves. Species in the genus are variously native to Latin America, Australia, New Zealand, Papuasia, Hawaii, insular Southeast Asia, Africa, and Madagascar. The stalks of some species are edible.
Athrotaxis is a genus of two to three species of conifers in the cypress family, Cupressaceae. The genus is endemic to western Tasmania, where they grow in high-elevation temperate rainforests.
Pyrophytes are plants which have adapted to tolerate fire.
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.
Muir Grove is a giant sequoia grove in Sequoia National Park of the Tulare County, which covers about 215 acres (0.87 km2). The grove, located in the northwest corner of the park, is accessed by the Muir Grove Trail which begins from the Dorst Creek Campground. Because of its relatively remote location in the park, it is significantly less visited than the more popular groves of large sequoia trees in the park. The isolated atmosphere helps keep Muir Grove untouched and preserved.
Sequoia sempervirens is the sole living species of the genus Sequoia in the cypress family Cupressaceae. Common names include coast redwood, coastal redwood, and California redwood. It is an evergreen, long-lived, monoecious tree living 1,200–2,200 years or more. This species includes the tallest living trees on Earth, reaching up to 115.9 m (380.1 ft) in height and up to 8.9 m (29 ft) in diameter at breast height. These trees are also among the longest-living organisms on Earth. Before commercial logging and clearing began by the 1850s, this massive tree occurred naturally in an estimated 810,000 ha along much of coastal California and the southwestern corner of coastal Oregon within the United States.
S. giganteum may refer to:
Sequoioideae, commonly referred to as redwoods, is a subfamily of coniferous trees within the family Cupressaceae. It includes the largest and tallest trees in the world. The subfamily achieved its maximum diversity during the Jurassic and Cretaceous periods.
Sequoia is a genus of redwood coniferous trees in the subfamily Sequoioideae of the family Cupressaceae. The only extant species of the genus is Sequoia sempervirens in the Northern California coastal forests ecoregion of Northern California and Southwestern Oregon in the United States. The two other genera in the subfamily Sequoioideae, Sequoiadendron and Metasequoia, are closely related to Sequoia. It includes the tallest trees, as well as the heaviest, in the world.
During most of the Late Cretaceous the eastern half of North America formed Appalachia, an island land mass separated from Laramidia to the west by the Western Interior Seaway. This seaway had split North America into two massive landmasses due to a multitude of factors such as tectonism and sea-level fluctuations for nearly 40 million years. The seaway eventually expanded, divided across the Dakotas, and by the end of the Cretaceous, it retreated towards the Gulf of Mexico and the Hudson Bay. This left the island masses joined in the continent of North America as the Rocky Mountains rose. From the Cenomanian to the end of the Campanian ages of the Late Cretaceous, Appalachia was separated from the rest of North America. As the Western Interior Seaway retreated in the Maastrichtian, Laramidia and Appalachia eventually connected. Because of this, its fauna was isolated, and developed very differently from the tyrannosaur, ceratopsian, hadrosaurid, pachycephalosaur and ankylosaurid dominated fauna of the western part of North America, known as "Laramidia".
Sequoiadendron chaneyi is an extinct species of tree in the Cupressaceae genus Sequoiadendron. Known from Miocene fossils found in Nevada and California, S. chaneyi is the oldest species of Sequoiadendron. The common use of the name "sequoia" generally refers to Sequoiadendron giganteum, which occurs naturally only in the various groves that exist on the western slopes of the Sierra Nevada of California. S. chaneyi is considered the probable direct ancestor to the extant Sequoiadendron giganteum.
The two giant sequoias near Kölpin in the parish of Demen in the district of Ludwigslust-Parchim in the German state of Mecklenburg-Vorpommern, are a natural monument. They belong to the species commonly known as giant sequoia, but also Wellingtonia and Sierra redwood.
Sequoia affinis is an extinct species of the genus Sequoia in the cypress family Cupressaceae.
The Sequoia and Kings Canyon National Parks is the consolidated management structure for Sequoia National Park and Kings Canyon National Park in California. The two parks have been jointly administered since 1943. They have a combined size of 1,353 square miles (3,500 km2). It was designated the UNESCO Sequoia-Kings Canyon Biosphere Reserve in 1976.
