California Coast Ranges (reserve)
The California Coast Ranges Biosphere Reserve (established 1983) was a UNESCO Biosphere reserve located along the California Coast Ranges of northern California and the San Francisco Bay area until June 2017. This biosphere reserve includes a highly diverse complex of evergreen sclerophyllous woodland, coastal, estuary and marine ecosystems. Purpose The city of San Francisco is a focal point for coastal industry and trade. Tourism, some agriculture and fisheries, transportation, manufacturing, military installations, and research and educational institutions are also important to the regional economy. The primary aim of the biosphere reserve is to develop a commitment to ecosystem management among the various management agencies. Given the intense human pressure of the area, the conservation of biodiversity is very challenging. Of particular concern is to raise environmental awareness among the diverse urban communities.

Lady Bird Johnson Grove - Redwood State Park, California (22773949741)
The word ''lady'' is a term for a girl or woman, with various connotations. Once used to describe only women of a high social class or status, the equivalent of lord, now it may refer to any adult woman, as gentleman can be used for men. Informal use is sometimes euphemistic ("lady of the night" for prostitute) or, in American slang, condescending in direct address (equivalent to "mister" or "man"). "Lady" is also a formal title in the United Kingdom. "Lady" is used before the family name of a woman with a title of nobility or honorary title ''suo jure'' (in her own right), or the wife of a lord, a baronet, Scottish feudal baron, laird, or a knight, and also before the first name of the daughter of a duke, marquess, or earl. Etymology The word comes from Old English '; the first part of the word is a mutated form of ', "loaf, bread", also seen in the corresponding ', "lord". The second part is usually taken to be from the root ''dig-'', "to knead", seen also in dough; the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Redwood Experimental Forest
The Redwood Experimental Forest (also Yurok Redwood Experimental Forest, formerly Yurok Experimental Forest) (established 1940) is an experimental forest in Del Norte County, California. The forest is near the mouth of the Klamath River in the California Coast Ranges of Northern California. The forest is drained by High Prairie Creek. As its name implies, the principal species in the forest is coast redwood (''Sequoia sempervirens''), but the site also contains Douglas fir, Sitka spruce, western hemlock, and Port Orford cedar. The forest is managed by the United States Forest Service. Tree ages range up to 1,200 years. Topography varies considerably over the forest. Slopes range from 0 to over 75 percent, and elevation ranges from . About 45 percent of the total area was clearcut between 1956 and 1985. About 1 percent was harvested in 1981 using the selection system. An additional 23 percent is available for approved manipulative research studies, and 16 percent is preserved in ...

Umbellularia
''Umbellularia californica'' is a large hardwood tree native to coastal forests and the Sierra foothills of California, and to coastal forests extending into Oregon. It is endemic to the California Floristic Province. It is the sole species in the genus ''Umbellularia''. The tree was formerly known as ''Oreodaphne californica''. In Yuki, it is called pōl’-cum ōl. In Oregon, this tree is known as Oregon myrtle, while in California it is called California bay laurel, which may be shortened to California bay or California laurel. It has also been called pepperwood, spicebush, cinnamon bush, peppernut tree, headache tree, mountain laurel, and balm of heaven. The tree's pungent leaves have a similar flavor to bay leaves, though stronger, and it may be mistaken for bay laurel. The dry wood has a color range from blonde (like maple) to brown (like walnut). It is considered an excellent tonewood and is sought after by luthiers and woodworkers. The tree is a host of the pathogen tha ...

California Mixed Evergreen Forest
: California mixed evergreen forest is a plant community found in the mountain ranges of California and southwestern Oregon. The Mixed evergreen forest plant community is native to the Northern and Southern California Coast Ranges and Sierra Nevada of central and northern California; the Transverse Ranges and Peninsular Ranges of southern California; and the southwestern Oregon Coast Ranges. California mixed evergreen forests occur in ecoregions of the California Floristic Province, including in areas of the California chaparral and woodlands and its sub-ecoregions, Klamath-Siskiyou Mountains forests, Northern California coastal forests, and Sierra Nevada lower montane forest. The mixed evergreen forests of each ecoregion have slightly different species composition. Klamath-Siskiyou mixed evergreen forest The mixed evergreen forests of the Klamath Mountains-Siskiyou Mountains occur above 300 meters (1000 ft) elevation, and are of four main types. Douglas-fir forests are f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old-growth Forest
An old-growth forestalso termed primary forest, virgin forest, late seral forest, primeval forest, or first-growth forestis a forest that has attained great age without significant disturbance, and thereby exhibits unique ecological features, and might be classified as a climax community. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. More than one-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree height ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sequoia Sempervirens
''Sequoia sempervirens'' ()''Sunset Western Garden Book,'' 1995:606–607 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. It is an evergreen, long-lived, monoecious tree living 1,200–2,200 years or more. This species includes the tallest living trees on Earth, reaching up to in height (without the roots) and up to in diameter at breast height. These trees are also among the oldest living things on Earth. Before commercial logging and clearing began by the 1850s, this massive tree occurred naturally in an estimated along much of coastal California (excluding southern California where rainfall is not sufficient) and the southwestern corner of coastal Oregon within the United States. The name sequoia sometimes refers to the subfamily Sequoioideae, which includes ''S. sempervirens'' along with ''Sequoiadendron'' (gi ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
