Sequoioideae in the context of "Redwood forest"

Metasequoia glyptostroboides, the dawn redwood, is a fast-growing, endangered deciduous conifer. It is the sole living species of the genus Metasequoia, one of three genera in the subfamily Sequoioideae of the family Cupressaceae. It now survives in the wild only in wet lower slopes and montane river and stream valleys in the border region of Hubei and Hunan provinces and Chongqing municipality in south-central China, notably in Lichuan county in Hubei. Although the shortest of the redwoods, it can grow to 167 ft (51 m) in height.

In 1941, the genus Metasequoia was reported by paleobotanist Shigeru Miki [jp] as a widely distributed extinct genus based on fossils, before attracting considerable attention a few years later when small populations were found alive in central China. It is a well-known example of a living fossil species. Modern dawn redwood appears identical to its late Cretaceous ancestors. The tree faces considerable risks of extinction in its wild range due to deforestation; however, it has been planted extensively in arboreta worldwide, where it has proved a popular and fast-growing ornamental plant. If the species had not been discovered when it was, it might have become extinct before being investigated.

Sequoiadendron giganteum (also known as the giant sequoia, giant redwood, Sierra redwood or Wellingtonia) is a species of coniferous tree, classified in the family Cupressaceae in the subfamily Sequoioideae. Giant sequoia specimens are the largest trees on Earth. They are native to the groves on the western slopes of the Sierra Nevada mountain range of California but have been introduced, planted, and grown around the world.

The giant sequoia is listed as an endangered species by the IUCN with fewer than 80,000 remaining in its native California.

Big Sur (/ˈsɜːr/) is a rugged and mountainous section of the Central Coast of the U.S. state of California, between Carmel Highlands and San Simeon, where the Santa Lucia Mountains rise abruptly from the Pacific Ocean. It is frequently praised for its dramatic scenery. Big Sur has been called the "longest and most scenic stretch of undeveloped coastline in the contiguous United States", a sublime "national treasure that demands extraordinary procedures to protect it from development", and "one of the most beautiful coastlines anywhere in the world, an isolated stretch of road, mythic in reputation". The views, redwood forests, hiking, beaches, and other recreational opportunities have made Big Sur a popular destination for visitors from across the world. With 4.5 to 7 million visitors annually, it is among the top tourist destinations in the United States, comparable to Yosemite National Park, but with considerably fewer services, and less parking, roads, and related infrastructure.

Big Sur Village is a collection of small roadside businesses and homes. The larger region known as Big Sur does not have specific boundaries but is generally considered to include the 71-mile (114 km) segment of California State Route 1 between Malpaso Creek near Carmel Highlands in the north and San Carpóforo Creek near San Simeon in the south, as well as the entire Santa Lucia range between these creeks. The interior region is mostly uninhabited, while the coast remains relatively isolated and sparsely populated, with between 1,800 and 2,000 year-round residents and relatively few visitor accommodations scattered among four small settlements. The region remained one of the most inaccessible areas of California and the entire United States until, after 18 years of construction, the Carmel–San Simeon Highway (now signed as part of State Route 1) was completed in 1937. Along with the ocean views, this winding, narrow road, often cut into the face of towering seaside cliffs, dominates the visitor's experience of Big Sur. The highway has been closed more than 55 times by landslides, and in May 2017, a 2,000,000-cubic-foot (57,000 m) slide blocked the highway at Mud Creek, north of Salmon Creek near the San Luis Obispo County line, to just south of Gorda. The road was reopened on July 18, 2018.

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.

Several extinct species have been named from fossils, including Sequoia affinis (Western North America) and Sequoia magnifica (petrified wood from the Yellowstone National Park area).

Metasequoia, or dawn redwood, is a genus of fast-growing coniferous trees. It contains one extant (living) species, Metasequoia glyptostroboides, which is one of three extant species of conifers known as redwoods in the world. Metasequoia glyptostroboides is native to Lichuan county in Hubei, China. Although the shortest of the redwoods, it grows to at least 165 feet (50 meters) 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.

Together with Sequoia sempervirens (coast redwood) and Sequoiadendron giganteum (giant sequoia) of California, Metasequoia is classified in the Cupressaceae subfamily Sequoioideae. M. glyptostroboides is the only living species in its genus, but three fossil species are known. Sequoioideae and several other genera have been transferred from the former family Taxodiaceae to Cupressaceae based on DNA analysis.
