List Of Oldest Trees
This is a list of the oldest-known trees, as reported in reliable sources. Definitions of what constitutes an individual tree vary. In addition, tree ages are derived from a variety of sources, including documented "tree-ring" (dendrochronological) count core samples, and from estimates. For these reasons, this article presents three lists of "oldest trees," each using varying criteria. There are three tables of trees, which are listed by age and species. The first table includes trees for which a minimum age has been directly determined, either through counting or cross-referencing tree rings or through radiocarbon dating. Many of these trees may be even older than their listed ages, but the oldest wood in the tree has rotted away. For some old trees, so much of the center is missing that their age cannot be directly determined. Instead, estimates are made based on the tree's size and presumed growth rate. The second table includes trees with these estimated ages. The last table ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollen
Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and forensics. Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the anth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Los Ríos Region
The Los Ríos Region (Spanish: ''Región de Los Ríos'', , ''Region of the Rivers'') is one of Chile's 16 regions, the country's first-order administrative divisions. Its capital is Valdivia. It began to operate as a region on October 2, 2007, having been created by subdividing the Los Lagos Region in southern Chile. It consists of two provinces: Valdivia and the newly created Ranco Province, which was formerly part of Valdivia Province. Economy The region's economy is based on forestry, cattle farming, tourism, manufacturing, and services. Key industries include the Valdivia Pulp Mill, Valdivia's shipyards, and the dairy facilities located in La Unión. The population of the region was 380,181 according to the 2017 census. Approximately half of the population lives in the commune of Valdivia. Government and administration The capital of Los Rios Region is Valdivia. The region's 12 communes are distributed between 2 provinces. These are: :*Valdivia Province: Including Val ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cordillera Pelada
Cordillera Pelada (Spanish for Bald Range or Barren Range) is a mountain range in southern Los Ríos Region, southern Chile. It is located along the Pacific coast and forms part of the larger Chilean Coast Range. It got its name ''pelada'' from the Spanish word for bare or bald in reference to large fires that once burned the forests on the cordillera. From about 1750 to 1943, when the land between Maullín River and Valdivia was colonized by Spain and Chile, numerous fires of ''Fitzroya'' woods occurred in Cordillera Pelada. These fires were initiated by Spaniards, Chileans and Europeans. Earlier, from 1397 to 1750 the ''Fitzroya'' woods of Cordillera Pelada also suffered from fires that originated from lightning strikes and indigenous inhabitants. See also *Chilean Coast Range *Cordillera de Nahuelbuta *Cordillera de Mahuidanchi The Cordillera de Oncol (sometimes called Valdivian Coast Range) is a mountain range, located along the Pacific coast in southern Chile.

Fitzroya
''Fitzroya'' is a monotypic genus in the cypress family. The single living species, ''Fitzroya cupressoides'', is a tall, long-lived conifer native to the Andes mountains and coastal of southern Chile, and only to the Andes mountains Argentina, where it is an important member of the Valdivian temperate rain forests. Common names include ''alerce'' ("larch" in Spanish), ''lahuán'' (Spanish, from the Mapuche name ''lawal''), and Patagonian cypress. The genus was named in honour of Robert FitzRoy. Description ''Fitzroya cupressoides'' is the largest tree species in South America, normally growing to 40–60 m, but occasionally more than 70 m, and up to 5 m in trunk diameter. Its rough pyramidal canopy provides cover for the southern beech, laurel and myrtle. The largest known living specimen is Alerce Milenario in Alerce Costero National Park, Chile. It is more than 60 m tall, with a trunk diameter of 4.26 m. Much larger specimens existed before the spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alerce Milenario
Alerce Milenario is the largest tree in Chile's Alerce Costero National Park. While it has been on the list of oldest trees, this Alerce tree (''Fitzroya cupressoides)'' is now rivalling others to be possibly the oldest tree in the world. Jonathan Barichivich and Antonio Lara, of the Austral University of Chile, bored a partial hole into the tree as far as possible without damaging it. They used an increment borer—a T-shaped drill to excise a narrow cylinder of wood without harming the tree. The partial plug of wood yielded approximately 2,400 tightly spaced growth rings. They then used statistical modelling based on data from 2,400 trees. Barichivich's age estimate for the Alerce Milenario was 5,484 years old and with certainty that the tree is at least 5,000 years old. Geography The Alerce Milenario Tree is located in a ravine, in the Alerce Coster National Park, a Chilean Rain Forest. The park is 137 hectares (340 acres), and up to 1,048 m (3,438 feet) above sea level. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Mountains (California)
The White Mountains of California and Nevada are a triangular fault-block mountain range facing the Sierra Nevada across the upper Owens Valley. They extend for approximately as a greatly elevated plateau about wide on the south, narrowing to a point at the north, with elevations generally increasing south to north. The range's broad southern end is near the community of Big Pine, where Westgard Pass and Deep Springs Valley separate it from the Inyo Mountains. The narrow northern end is at Montgomery Pass, where U.S. Route 6 crosses. The Fish Lake Valley lies east of the range; the southeast part of the mountains are separated from the Silver Peak Range by block faulting across the Furnace Creek Fault Zone, forming a feeder valley to Fish Lake Valley. The range lies within the eastern section of the Inyo National Forest. Ecology Ecologically, the White Mountains are like the other ranges in the Basin and Range Province; they are dry, but the upper slopes from hold open suba ...

Methuselah (tree)
Methuselah is a -year-old Great Basin bristlecone pine (''Pinus longaeva'') tree growing high in the White Mountains of Inyo County in eastern California. It is recognized as the non- clonal tree with the greatest confirmed age in the world. The tree's name refers to the biblical patriarch Methuselah, who ostensibly lived to 969 years of age, thus becoming synonymous with longevity or old age in many European languages including English. Geography Methuselah is located between above sea level in the "Methuselah Grove" in the Ancient Bristlecone Pine Forest within the Inyo National Forest. The United States Forest Service does not disclose its exact location. Status as oldest known tree Methuselah was 4,789 years old when sampled in 1957 by Edmund Schulman and Tom Harlan, with an estimated germination date of 2833 BC. Since this tree ages back to this date, using tree rings, research shows precipitation patterns that date back to 1983 BC. Dendrochronologist Matthew Salzer ...

Donald Rusk Currey
Donald Rusk Currey (January 24, 1934 – June 6, 2004) was an American professor of geography. While known in academia for his extensive research and exploration of relics of the ancient Lake Bonneville in the eastern Great Basin, he was best known to the public for his controversial felling of Prometheus, the oldest living non-clonal organism known at the time, while a graduate student in 1964. Prometheus controversy Discovery and felling In 1963, Currey was a graduate student at the University of North Carolina at Chapel Hill. Under a fellowship from the National Science Foundation, Currey was studying the climate dynamics of the Little Ice Age using dendrochronology techniques. The Bristlecone pines that grow in California, Nevada and Utah were discovered to be older than any species yet dated, and in 1963 Currey became aware of a Great Basin Bristlecone Pine population in the Snake Range and on Wheeler Peak in eastern Nevada in particular. At the time he visited the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
