Redwood National And State Parks
The Redwood National and State Parks (RNSP) are a complex of one national park and three state parks, cooperatively managed, located in the United States along the coast of northern California. Comprising Redwood National Park (established 1968) and California's State Parks: Del Norte Coast, Jedediah Smith, and Prairie Creek (dating from the 1920s), the combined RNSP contain , and feature old-growth temperate rainforests. Located within Del Norte and Humboldt Counties, the four parks, protect 45 percent of all remaining coast redwood (''Sequoia sempervirens'') old-growth forests, totaling at least . These trees are the tallest, among the oldest, and one of the most massive tree species on Earth. In addition to the redwood forests, the parks preserve other indigenous flora, fauna, grassland prairie, cultural resources, waterways, and of pristine coastline. In 1850, old-growth redwood forest covered more than of the California coast. The northern portion of that area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gold Rush
A gold rush or gold fever is a discovery of gold—sometimes accompanied by other precious metals and rare-earth minerals—that brings an onrush of miners seeking their fortune. Major gold rushes took place in the 19th century in Australia, New Zealand, Brazil, Chile, South Africa, the United States, and Canada while smaller gold rushes took place elsewhere. In the 19th century, the wealth that resulted was distributed widely because of reduced migration costs and low barriers to entry. While gold mining itself proved unprofitable for most diggers and mine owners, some people made large fortunes, and merchants and transportation facilities made large profits. The resulting increase in the world's gold supply stimulated global trade and investment. Historians have written extensively about the mass migration, trade, colonization, and environmental history associated with gold rushes. Gold rushes were typically marked by a general buoyant feeling of a "free-for-all" in income m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yurok Plankhouse05
The Yurok (Karuk language: Yurúkvaarar / Yuru Kyara - "downriver Indian; i.e. Yurok Indian") are an Indigenous people from along the Klamath River and Pacific coast, whose homelands are located in present-day California stretching from Trinidad in the south to Crescent City in the north. The Yurok live on the Yurok Indian Reservation, Resighini Rancheria, and surrounding communities in Humboldt, Del Norte and Trinity counties. Although the reservation comprises some of contiguous land along the Klamath River, only about of scattered plots are under partial tribal ownership. Most Yurok land is owned by timber corporations or is part of national parks and forests. This forest management has significantly dis-empowered the Yurok people and disrupted their ability to access natural resources, land, and practice Indigenous lifeways. The Yurok refer to themselves as 'Oohl ("person") or 'O'loolekweesh 'o'l / 'Oolekwoh (lit. "'o'loolekw "village"dwellers"). Ner'ernerh / Nert'e ...

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. Sites The California Coast Ranges reserve encompasses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Heritage Site
A World Heritage Site is a landmark or area with legal protection by an international convention administered by the United Nations Educational, Scientific and Cultural Organization (UNESCO). World Heritage Sites are designated by UNESCO for having cultural, historical, scientific or other form of significance. The sites are judged to contain " cultural and natural heritage around the world considered to be of outstanding value to humanity". To be selected, a World Heritage Site must be a somehow unique landmark which is geographically and historically identifiable and has special cultural or physical significance. For example, World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains, or wilderness areas.

Steller's Sea Lion
The Steller sea lion (''Eumetopias jubatus''), also known as the Steller's sea lion and northern sea lion, is a near-threatened species of sea lion in the northern Pacific. It is the sole member of the genus ''Eumetopias'' and the largest of the eared seals (Otariidae). Among pinnipeds, only the walrus and the two species of elephant seals are bigger. The species is named for the naturalist Georg Wilhelm Steller, who first described them in 1741. The Steller sea lion has attracted considerable attention in recent decades, owing to significant and largely unexplained declines in their numbers over an extensive portion of their northern range in Alaska. Description Adult animals are lighter in color than most sea lions, ranging from pale yellow to tawny and occasionally reddish. Steller sea lion pups are born almost black, weighing around , and remain dark in coloration for several months. Females and males both grow rapidly until the fifth year, after which female growt ...

Threatened Species
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of '' critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species * Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data ( data deficient) also are not consid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
