Pershing (tree)
The giant sequoia ('' Sequoiadendron giganteum'') is the world's most massive tree, and arguably the largest living organism on Earth. It is neither the tallest extant species of tree (that distinction belongs to the coast redwood), nor is it the widest (that distinction belongs to the baobab tree or Montezuma cypresses), nor is it the longest-lived (that distinction belongs to the Great Basin bristlecone pine). However, with a height of or more, a circumference of or more, an estimated bole volume of up to , and a documented lifespan of 3266 years, the giant sequoia is among the tallest, widest, and longest-lived of all organisms on Earth. Giant sequoias grow in well-defined groves in California mixed evergreen forests, along with other old-growth species such as California incense-cedar ('' Calocedrus decurrens''). Because most of the neighboring trees are also quite large, it can be difficult to appreciate the size of an individual giant sequoia. The largest giant se ...

General Sherman 1469870071
A general officer is an officer of high rank in the armies, and in some nations' air forces, space forces, and marines or naval infantry. In some usages the term "general officer" refers to a rank above colonel."general, adj. and n.". OED Online. March 2021. Oxford University Press. https://www.oed.com/view/Entry/77489?rskey=dCKrg4&result=1 (accessed May 11, 2021) The term ''general'' is used in two ways: as the generic title for all grades of general officer and as a specific rank. It originates in the 16th century, as a shortening of '' captain general'', which rank was taken from Middle French ''capitaine général''. The adjective ''general'' had been affixed to officer designations since the late medieval period to indicate relative superiority or an extended jurisdiction. Today, the title of ''general'' is known in some countries as a four-star rank. However, different countries use different systems of stars or other insignia for senior ranks. It has a NATO ...

Heart Rot
300px, The bracket fungus '' Fistulina hepatica'' is one of many that cause heart rot. In trees, heart rot is a fungal disease that causes the decay of wood at the center of the trunk and branches. Fungi enter the tree through wounds in the bark and decay the heartwood. The diseased heartwood softens, making trees structurally weaker and prone to breakage. Heart rot is a major factor in the economics of logging and the natural growth dynamic of many older forests. Heart rot is prevalent throughout the world affecting all hardwood trees and can be very difficult to prevent. A good indication of heart rot is the presence of mushrooms or fungus conks on the tree. Biological cause Heart rot is caused by fungi entering the trunk of the tree through wounds in the bark. These wounds are areas of the tree where bare wood is exposed and usually, a result of improper pruning, fire damage, dead branches, insects, or even animal damage. The fungal spores enter the exposed wounds, germinate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laminated Root Rot
Laminated root rot also known as yellow ring rot is caused by the fungal pathogen ''Phellinus weirii''. Laminated root rot is one of the most damaging root disease amongst conifers in northwestern America and true firs, Douglas fir, Mountain hemlock, and Western hemlock are highly susceptible to infection with ''P. weirii''. A few species of plants such as Western white pine and Lodgepole pine are tolerant to the pathogen while Ponderosa pine is resistant to it. Only hardwoods are known to be immune to the pathogen. Symptoms and signs The disease can infect trees as young as 6 years-old, and infects trees throughout their lifespan.Data sheets on quarantine pests: Phellinus weirii. In EPPO quarantine pest Retrieved from Diagnostic symptoms include crown yellowing and thinning, a distress crop of cones, red brown stained outer heartwood, and laminate decay (decay that separates along annual rings). The disease tends to occur in patches due to a primarily short range spread mechan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungus
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vascular Cambium
The vascular cambium is the main growth tissue in the stems and roots of many plants, specifically in dicots such as buttercups and oak trees, gymnosperms such as pine trees, as well as in certain other vascular plants. It produces secondary xylem inwards, towards the pith, and secondary phloem outwards, towards the bark. In herbaceous plants, it occurs in the vascular bundles which are often arranged like beads on a necklace forming an interrupted ring inside the stem. In woody plants, it forms a cylinder of unspecialized meristem cells, as a continuous ring from which the new tissues are grown. Unlike the xylem and phloem, it does not transport water, minerals or food through the plant. Other names for the vascular cambium are the main cambium, wood cambium, or bifacial cambium. Occurrence Vascular cambia are found in all seed plants except for five angiosperm lineages which have independently lost it; Nymphaeales, Ceratophyllum, Nelumbo, Podostemaceae, and monocots.

Bark (botany)
Bark is the outermost layers of stems and roots of woody plants. Plants with bark include trees, woody vines, and shrubs. Bark refers to all the tissues outside the vascular cambium and is a nontechnical term. It overlays the wood and consists of the inner bark and the outer bark. The inner bark, which in older stems is living tissue, includes the innermost layer of the periderm. The outer bark on older stems includes the dead tissue on the surface of the stems, along with parts of the outermost periderm and all the tissues on the outer side of the periderm. The outer bark on trees which lies external to the living periderm is also called the rhytidome. Products derived from bark include bark shingle siding and wall coverings, spices and other flavorings, tanbark for tannin, resin, latex, medicines, poisons, various hallucinogenic chemicals and cork. Bark has been used to make cloth, canoes, and ropes and used as a surface for paintings and map making. A number of plants a ...

List Of Giant Sequoia Groves
This is a list of giant sequoia groves. All naturally occurring giant sequoia groves are located in the moist, unglaciated ridges and valleys of the western slope of the Sierra Nevada range in California, United States. They can be found at elevations between . While many groves are within national park boundaries, such as Sequoia National Park and Yosemite National Park, most of the giant sequoia groves are under the care of the United States Forest Service, placing them outside the legislative mandate that excludes commercial timber harvest. Logging of non-sequoia timber continued as recently as the 1980, especially old-growth ponderosa and sugar pine, which have been logged almost to extinction amongst the groves. Groves in the northern half of the range (north of the Kings River) are widely scattered and host smaller collections of giant sequoias than groves found within and south of the Kings River watershed. The total area of all the groves combined is approximately . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Deer Creek Grove
Deer Creek Grove is a small giant sequoia grove located in the Deer Creek watershed of the Giant Sequoia National Monument in the western Sierra Nevada of California. The grove is located near the end of a steep trail south from the end of Deer Creek Mill Road. It is the southernmost giant sequoia grove. The grove is attractively situated about halfway up a pine-covered mountain that rises above a valley of grassy foothills. The grove consists of a scattered collection of old-growth giant sequoias on a sheltered east-facing slope. While the present day distribution of this species is limited to a small area of California, it was once much more widely distributed in prehistoric times, and was a reasonably common species in North American and Eurasian coniferous forests until its range was greatly reduced by the last ice age. This grove was heavily impacted by the Windy Fire The 2021 Windy Fire was a large wildfire in the Sequoia National Forest in Central California's T ...

Placer County, California
Placer County ( ; Spanish for "sand deposit"), officially the County of Placer, is a county in the U.S. state of California. As of the 2020 census, the population was 404,739. The county seat is Auburn. Placer County is included in the Greater Sacramento metropolitan area. It is in both the Sacramento Valley and Sierra Nevada regions, in what is known as the Gold Country. The county stretches roughly 65 miles (105 km) from Sacramento's suburbs at Roseville to the Nevada border and the shore of Lake Tahoe. Etymology The discovery of gold in 1848 brought tens of thousands of miners from around the world during the California Gold Rush. In addition, many more thousands came to provide goods and services to the miners. On April 25, 1851, the fast-growing county was formed from parts of Sutter and Yuba Counties with Auburn as the county seat. Placer County took its name from the Spanish word for sand or gravel deposits containing gold. Miners washed away the gravel, leaving ...
