Washington (tree)
The Washington tree is a giant sequoia in the Giant Forest Grove in Tulare County, California, within Sequoia National Park. It is named after George Washington, first President of the United States. Until it partially collapsed in January 2005, the Washington tree was the second largest tree in the world (after the General Sherman tree). Though badly damaged, the tree is still living. Before damage The tree was studied in 1999 by scientists from Humboldt State University and University of Washington. The tree was tall, with a basal diameter of . Its total volume was , including the main stem and the 46 largest branches . The scientists discovered a large cavity in the trunk of the tree, measuring in height by in diameter. The cavity was accessible only by a hole situated above the ground. The significance of this finding is that the volume of wood in the tree had been greatly overestimated by previous measurements. Damage and collapse In September 2003, a fire caused ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crown Snow-load
Crown snow-load is snow and hard rime that accumulates on tree crowns in a cold climate. There are two main climatic conditions in which this phenomenon chiefly takes place. Hard rime is formed when subcooled droplets of fog or low-level stratus cloud freeze on the windward (wind-facing) side of tree branches, buildings, or any other solid objects. This takes place usually with moderate wind speeds from and air temperatures between . Snow may accumulate directly on the trees when a warm front brings wet snow, the air temperature is slightly above the freezing point and the surface of the tree is colder due to a preceding cold spell. In Scandinavia, largest snow-loads accumulate to the trees on top of medium-sized fell A fell (from Old Norse ''fell'', ''fjall'', "mountain"Falk and Torp (2006:161).) is a high and barren landscape feature, such as a mountain or moor-covered hill.

National Park Service
The National Park Service (NPS) is an agency of the United States federal government within the U.S. Department of the Interior that manages all national parks, most national monuments, and other natural, historical, and recreational properties with various title designations. The U.S. Congress created the agency on August 25, 1916, through the National Park Service Organic Act. It is headquartered in Washington, D.C., within the main headquarters of the Department of the Interior. The NPS employs approximately 20,000 people in 423 individual units covering over 85 million acres in all 50 states, the District of Columbia, and US territories. As of 2019, they had more than 279,000 volunteers. The agency is charged with a dual role of preserving the ecological and historical integrity of the places entrusted to its management while also making them available and accessible for public use and enjoyment.

Crown (botany)
The crown of a plant refers to the total of an individual plant's aboveground parts, including stems, leaves, and reproductive structures. A plant community canopy consists of one or more plant crowns growing in a given area. The crown of a woody plant (tree, shrub, liana) is the branches, leaves, and reproductive structures extending from the trunk or main stems. Shapes of crowns are highly variable. The major types for trees are the excurrent branching habit resulting in conoid shapes and decurrent (deliquescent) branching habit, resulting in round shapes. Crowns are also characterized by their width, depth, surface area, volume, and density. Measurements of crowns are important in quantifying and qualifying plant health, growth stage, and efficiency. Major functions of the crown include light energy assimilation, carbon dioxide absorption and release of oxygen via photosynthesis, energy release by respiration, and movement of water to the atmosphere by transpiration. ...

Lightning Strike
A lightning strike or lightning bolt is an electric discharge between the atmosphere and the ground. Most originate in a cumulonimbus cloud and terminate on the ground, called cloud-to-ground (CG) lightning. A less common type of strike, ground-to-cloud (GC) lightning, is upward-propagating lightning initiated from a tall grounded object and reaching into the clouds. About 25% of all lightning events worldwide are strikes between the atmosphere and earth-bound objects. Most are intracloud (IC) lightning and cloud-to-cloud (CC), where discharges only occur high in the atmosphere. Lightning strikes the average commercial aircraft at least once a year, but modern engineering and design means this is rarely a problem. The movement of aircraft through clouds can even cause lightning strikes. A single lightning event is a "flash", which is a complex, multistage process, some parts of which are not fully understood. Most CG flashes only "strike" one physical location, referred to as a " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trunk (botany)
In botany, the trunk (or bole) is the stem and main wooden axis of a tree, which is an important feature in tree identification, and which often differs markedly from the bottom of the trunk to the top, depending on the species. The trunk is the most important part of the tree for timber production. Occurrence Trunks occur both in "true" woody plants and non-woody plants such as palms and other monocots, though the internal physiology is different in each case. In all plants, trunks thicken over time due to the formation of secondary growth (or in monocots, pseudo-secondary growth). Trunks can be vulnerable to damage, including sunburn. Vocabulary Trunks which are cut down for making lumber are generally called logs; if they are cut to a specific length, called bolts. The term "log" is informally used in English to describe any felled trunk not rooted in the ground, whose roots are detached. A stump is the part of a trunk remaining in the ground after the tree has been f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sequoiadendron Giganteum
''Sequoiadendron giganteum'' (giant sequoia; also known as giant redwood, Sierra redwood, Sierran redwood, California big tree, Wellingtonia or simply big treea nickname also used by John Muir) 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'' (coast redwood) and '' Metasequoia glyptostroboides'' (dawn redwood). 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. The giant sequoia is listed as an endangered species by the IUCN, with fewer than 80,000 trees remaining. Since its last assessment as an endangered species in 2011, it was estimated that another 13–19% of the population (or 9,761–13 ...

General Sherman (tree)
General Sherman is a giant sequoia ('' Sequoiadendron giganteum'') tree located in the Giant Forest of Sequoia National Park in Tulare County, in the U.S. state of California. By volume, it is the largest known living single-stem tree on Earth. It is estimated to be around 2,200 to 2,700 years old. While General Sherman is the largest currently living tree, it is not the largest historically recorded tree. The Lindsey Creek tree, with more than almost twice the volume of General Sherman, was reported felled by a storm in 1905. Another larger tree, the Crannell Creek Giant, a coast redwood ('' Sequoia sempervirens'') cut down in the mid-1940s near Trinidad, California, is estimated to have been 15–25% larger than the General Sherman Tree by volume. History The General Sherman Tree was named after the American Civil War general William Tecumseh Sherman. The official story, which may be apocryphal, claims the tree was named in 1879 by naturalist James Wolverton, who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
