Ancient Bristlecone Pine Forest
The Ancient Bristlecone Pine Forest is a protected area high in the White Mountains (California), White Mountains in Inyo County, California, Inyo County in eastern California. Geography The forest is east of the Owens Valley, high on the eastern face of the White Mountains in the upper Fish Lake-Soda Spring Drainage basin, Watershed, above the northernmost reach of the Mojave Desert into Great Basin ecotone. The forest's mountain habitat is in the Central Basin and Range ecoregion (EPA) and Taiga, Taiga and Boreal forest ecoregion (WWF). The Patriarch Grove is the source of Cottonwood Creek (Inyo County, California), Cottonwood Creek, a designated Wild and Scenic River. Ecology The Pinus longaeva, Great Basin bristlecone pine (''Pinus longaeva'') trees grow between 9,800 and 11,000 feet (3,000–3,400 m) above sea level, in xeric alpine conditions, protected within the Inyo National Forest.

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 ...

Cottonwood Creek (Inyo County, California)
Cottonwood Creek originates in the Ancient Bristlecone Pine Forests of the White Mountains of eastern California. The creek flows eastward from below the alpine crest of the White Mountains and descends through groves of bristlecone pine, aspen and mountain mahogany, then a woodland of pinyon pine and juniper, and finally into sagebrush as the stream ends in endorheic Fish Lake Valley which is one of the contiguous collection of inward-draining basins that make up the Great Basin. Cottonwood Creek has no native fish, however its North Fork is a refuge for the threatened Paiute cutthroat trout, one of the rarest trout in North America. This subspecies was transplanted from its very limited native range, upper Silver King Creek in the Carson River basin. The remainder of the stream hosts (originally) transplanted brook, brown and rainbow A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in ...

Protected Areas Of The Great Basin
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servin ...

Taiga And Boreal Forests In The United States
Taiga (; rus, тайга́, p=tɐjˈɡa; relates to Mongolic and Turkic languages), generally referred to in North America as a boreal forest or snow forest, is a biome characterized by coniferous forests consisting mostly of pines, spruces, and larches. The taiga or boreal forest has been called the world's largest land biome. In North America, it covers most of inland Canada, Alaska, and parts of the northern contiguous United States. In Eurasia, it covers most of Sweden, Finland, much of Russia from Karelia in the west to the Pacific Ocean (including much of Siberia), much of Norway and Estonia, some of the Scottish Highlands, some lowland/coastal areas of Iceland, and areas of northern Kazakhstan, northern Mongolia, and northern Japan (on the island of Hokkaidō). The main tree species, depending on the length of the growing season and summer temperatures, vary across the world. The taiga of North America is mostly spruce, Scandinavian and Finnish taiga consists of a mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forests Of California
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Los Angeles Times
The ''Los Angeles Times'' (abbreviated as ''LA Times'') is a daily newspaper that started publishing in Los Angeles in 1881. Based in the LA-adjacent suburb of El Segundo since 2018, it is the sixth-largest newspaper by circulation in the United States. The publication has won more than 40 Pulitzer Prizes. It is owned by Patrick Soon-Shiong and published by the Times Mirror Company. The newspaper’s coverage emphasizes California and especially Southern California stories. In the 19th century, the paper developed a reputation for civic boosterism and opposition to labor unions, the latter of which led to the bombing of its headquarters in 1910. The paper's profile grew substantially in the 1960s under publisher Otis Chandler, who adopted a more national focus. In recent decades the paper's readership has declined, and it has been beset by a series of ownership changes, staff reductions, and other controversies. In January 2018, the paper's staff voted to unionize and final ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vegetative Cloning
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules. Many plants naturally reproduce this way, but it can also be induced artificially. Horticulturists have developed asexual propagation techniques that use vegetative propagules to replicate plants. Success rates and difficulty of propagation vary greatly. Monocotyledons typically lack a vascular cambium, making them more challenging to propagate. Background Plant propagation is the process of plant reproduction of a species or cultivar, and it can be sexual or asexual. It can happen through the use of vegetative parts of the plants, such as leaves, stems, and roots to produce new plants or through growth from specialized vegetative plant parts. While man ...

Pinus Flexilis
''Pinus flexilis'', the limber pine, is a species of pine tree-the family Pinaceae that occurs in the mountains of the Western United States, Mexico, and Canada. It is also called Rocky Mountain white pine. A limber pine in Eagle Cap Wilderness, Oregon, has been documented as over 2,000 years old, and another one was confirmed at 1,140 years old. Another candidate for the oldest limber pine was identified in 2006 near the Alta Ski Area in Utah; called "Twister", the tree was confirmed to be at least 1,700 years old and thought to be even older. Description Its pliant branches gives it the common name "limber" and specific epithet ''flexilis''. Its needles are about long and a dark, blueish green. Its bark is heavily creased and dark grey. Its pale wood is lightweight and soft. ''Pinus flexilis'' is typically a high-elevation pine, often marking the tree line either on its own, or with whitebark pine (''Pinus albicaulis''), either of the bristlecone pines, or lodgepole pine ...

Inyo National Forest
Inyo National Forest is a United States National Forest covering parts of the eastern Sierra Nevada of California and the White Mountains of California and Nevada. The forest hosts several superlatives, including Mount Whitney, the highest point in the contiguous United States; Boundary Peak, the highest point in Nevada; and the Ancient Bristlecone Pine Forest, which protects the oldest living trees in the world. The forest, encompassing much of the Owens Valley, was established by Theodore Roosevelt as a way of sectioning off land to accommodate the Los Angeles Aqueduct project in 1907, making the Inyo National Forest one of the least wooded forests in the U.S. National Forest system. Geography The forest covers and includes nine designated wilderness areas which protect over . Most of the forest is in California, but it includes about in western Nevada. It stretches from the eastern side of Yosemite to south of Sequoia National Park. Geographically it is split in two, one ...
