The IUCN Red List Category & Criteria assesses Sequoia sempervirens as Endangered (A2acd), Sequoiadendron giganteum as Endangered (B2ab) and Metasequoia glyptostroboides as Endangered (B1ab). Thanks so much for this article -- my daughter remembered at the last minute that she had a project due tomorrow on redwood tree facts, and you know how that goes. I would really like to know where I can find info on every different species that live on the CA coast. an M.A. "Revision of Fossil Sequoia and Taxodium in Western North America Based on the Recent Discovery of Metasequoia", 10.3374/0079-032x(2007)48[281:wdmdfn];2, "Kia Ora – Welcome to The Redwoods Whakarewarewa Forest", "A few basic facts about Redwoods, and Parks", de:Liste der dicksten Mammutbäume in Deutschland,, Articles with incomplete citations from September 2018, Short description is different from Wikidata, Creative Commons Attribution-ShareAlike License. Now we come to the two broadleaf family of redwood trees, neither of which are as large as the Family Cupressaceae. Sequoia sempervirens /sɪˈkɔɪ.ə sɛmpərˈvaɪrənz/ is the sole living species of the genus Sequoia in the cypress family Cupressaceae (formerly treated in Taxodiaceae). It is most common in the coastal forests of Northern California and is known for being the largest tree in the world. These trees can live for thousands of years. Trees of Metasequoia, from the single living species Metasequoia glyptostroboides, are much smaller. Next is the Coast Redwood, or Sequoia sempervirens. Whenever you're desperately in need of information, it's almost impossible to find. [10], Sequoioideae is an ancient taxon, with the oldest described Sequoioideae species, Sequoia jeholensis, recovered from Jurassic deposits. ə s ɛ m p ər ˈ v aɪ r ən z / is the sole living species of the genus Sequoia in the cypress family Cupressaceae (formerly treated in Taxodiaceae).Common names include coast redwood, coastal redwood and California redwood. Even though I was young at the time, I still remember how enormously large those things were -- the thing that really made it stick out in my mind was seeing how small my dad looked next to them, since you know how it is when you're young, you think your dad is the biggest thing in the world. Areas known as alluvial flats are where many of the tallest trees grow. [6][7][8][9], Most modern phylogenies place Sequoia as sister to Sequoiadendron and Metasequoia as the out-group. It is called both "Giant Sequoia" and "Sierra Redwood. The main one featured in these pages is the one known as the Giant Redwood, or Wellingtonia. She has also edited several Its true scientific name is Sequoiadendron giganteum . I had thought for some reason that redwood trees only grew in the American west, because you always see pictures of the Yosemite redwood trees and the redwood tree parks in CA. In addition to her work as a freelance writer for wiseGEEK, Diane is the executive editor of It is most common in the coastal forests of Northern California and is possibly the largest tree in the world. Is Amazon actually giving you the best price? [7][9][10] However, Yang et al. These trees can live for thousands of years. The coast redwood (Sequoia sempervirens) is the sole living species of the genus Sequoia in the cypress family Cupressaceae.Common names include coast redwood, California redwood, and giant redwood. To investigate the origins of this polyploidy Yang et al. went on to investigate the origin of a peculiar genetic artifact of the Sequoioideae—the polyploidy of Sequoia—and generated a notable exception that calls into question the specifics of this relative consensus. Version 2013.2. The Brazilwood tree, for example, is native to Brazil. Threats include: logging, fire suppression , climate change, illegal marijuana cultivation, and burl poaching. Both species of trees are REDWOOD, the same as two pines are both Pines, though one may be called Digger Pine and the other may be known as Sugar Pine. from Brooklyn College.

I have planted hundreds of redwood trees and have started my own "forest", mostly starting from suckers I have cut from other redwoods. Sequoia sempervirens is hexaploid (2n= 6x= 66). See Also: (10 Facts about Rafflesia) Redwood Tree. However, the long evolutionary history of the three genera (the earliest fossil remains being from the Jurassic) make resolving the specifics of when and how Sequoia originated once and for all a difficult matter—especially since it in part depends on an incomplete fossil record. From the wind-pruned, salt-tolerant Sitka spruce by the seaside, to the cool, moist redwood groves, and sunny, open grasslands of the prairies, visitors can find an interconnected community of greenery. The Giant Sequoia, for another example, grows primarily in California. The redwood species contains the largest and tallest trees in the world. from Sarah Lawrence College and Giant sequoias and California redwoods (also called coast redwoods) are nature's skyscrapers. The Family Sterculiaceae, like the coniferous Family Pinaceae, only includes one redwood.
