Salmon River (California)
The Salmon River is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed March 9, 2011 tributary to the Klamath River in western Siskiyou County, California. Course The river has its origins in the high mountains of the Trinity Alps, Russian Mountains, and Marble Mountains (all sub-ranges of the larger Klamath Mountains). The Salmon River comprises two forks, the North Fork and the South Fork, which join at the hamlet of Forks of Salmon, California to form the 19.6-mile (31.5 km) long mainstem Salmon River. A large tributary stream, Wooley Creek, joins the mainstem Salmon River about from its mouth at Somes Bar, and is nearly as large as the North Fork. The lower portion of the Salmon River's southwestern divide defines the boundary of Siskiyou County and Humboldt County. Watershed The river's watershed is entirely within the Klamath National Forest, and less than two percent of the land area is privately own ...

Russian Wilderness
The Russian Wilderness is a wilderness area of located approximately northeast of Eureka, California, Eureka in northern California. It is within the Klamath National Forest in Siskiyou County and is managed by the US Forest Service. It was added to the National Wilderness Preservation System when the US Congress passed the California Wilderness Act of 1984. The Russian Wilderness protects the Russian Mountains, a portion of the high crest of the Salmon Mountains, which are composed of metamorphic and granitic rock. There are over twenty named lakes at different elevation levels as well as the major watersheds of the Scott River and North Fork Salmon River (California), North Fork Salmon River. The Russian is one of three wilderness areas that form an almost continuous chain, from the Trinity Alps Wilderness to the south, and the Marble Mountain Wilderness in the north, these areas provide an important corridor for wildlife such as the migrating herds of black-tailed deer.

Erosion
Erosion is the action of surface processes (such as Surface runoff, water flow or wind) that removes soil, Rock (geology), rock, or dissolved material from one location on the Earth's crust#Crust, Earth's crust and then sediment transport, transports it to another location where it is deposit (geology), deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by Solvation, dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and Wind wave, waves; glacier, glacial Plucking (glaciation), plucking, Abrasion (geology), abrasion, and scour; areal flooding; Aeolian processes, wind abrasion; groundwater processes; and Mass wastin ...

Slash (logging)
In forestry, slash, or slashings are coarse and fine woody debris generated during logging operations or through wind, snow or other natural forest disturbances. Slash generated during logging operations may increase fire hazard, and some North American states have passed laws requiring the treatment of logging slash. Logging slash can be chipped and used (for example) in the production of electricity or heat in cogeneration power-plants, or simply burned onsite. Where logging takes place on soft ground, loggers can use the branches and tops of trees as part of the timber-harvesting process to provide a track for forest machines. Using slash in this manner reduces ground damage. See also * Coarse woody debris * Lignocellulosic biomass Lignocellulose refers to plant dry matter (biomass), so called lignocellulosic biomass. It is the most abundantly available raw material on the Earth for the production of biofuels. It is composed of two kinds of carbohydrate polymers, cel ...

Ecosystem
An ecosystem (or ecological system) is a system formed by Organism, organisms in interaction with their Biophysical environment, environment. The Biotic material, biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal Environmental factor, factors. External factors—including climate—control the ecosystem's structure, but are not influenced by it. By contrast, internal factors control and are controlled by ecosystem processes; these include decomposition, the types of species present, root competition, shading, disturbance, and succession. While external factors generally determine which Resource (biology), resource inputs an ecosystem has, their availability within the ecosystem is controlled by internal factors. Ecosystems are wikt:dynamic, dynamic, subject to periodic disturbances and always in the process of recovering from past disturbances. The tendency of an ecosystem to remain clo ...

Wildfire
A wildfire, forest fire, or a bushfire is an unplanned and uncontrolled fire in an area of Combustibility and flammability, combustible vegetation. Depending on the type of vegetation present, a wildfire may be more specifically identified as a bushfire (Bushfires in Australia, in Australia), desert fire, grass fire, hill fire, Peat#Peat fires, peat fire, prairie fire, vegetation fire, or veld fire. Some natural forest ecosystems Fire ecology, depend on wildfire. Modern forest management often engages in prescribed burns to mitigate fire risk and promote natural forest cycles. However, controlled burns can turn into wildfires by mistake. Wildfires can be classified by cause of ignition, physical properties, combustible material present, and the effect of weather on the fire. Wildfire severity results from a combination of factors such as available fuels, physical setting, and weather. Climatic cycles with wet periods that create substantial fuels, followed by drought and heat, of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Wild And Scenic Rivers System
The National Wild and Scenic Rivers System was created by the Wild and Scenic Rivers Act of 1968 (Public Law 90-542), enacted by the U.S. Congress to preserve certain rivers with outstanding natural, cultural, and recreational values in a free-flowing condition for the enjoyment of present and future generations. The Act is notable for safeguarding the special character of these rivers, while also recognizing the potential for their appropriate use and development. It encourages river management that crosses political boundaries and promotes public participation in developing goals for river protection. The Act, signed into law by President Lyndon B. Johnson in the height of the United States environmental era, states:"It is hereby declared to be the policy of the United States that certain selected rivers of the Nation which, with their immediate environments, possess outstandingly remarkable scenic, recreational, geologic, fish and wildlife, historic, cultural or other similar ...

West Coast Of The United States
The West Coast of the United States, also known as the Pacific Coast and the Western Seaboard, is the coastline along which the Western United States meets the North Pacific Ocean. The term typically refers to the Contiguous United States, contiguous U.S. states of California, Oregon, and Washington (state), Washington, but it occasionally includes Alaska and Hawaii in bureaucratic usage. For example, the United States Census Bureau, U.S. Census Bureau considers both states to be part of a larger U.S. geographic division. Definition There are conflicting definitions of which states comprise the West Coast of the United States, but the West Coast always includes California, Oregon, and Washington (state), Washington as part of that definition. Under most circumstances, however, the term encompasses the three contiguous states and Alaska, as they are all located in North America. For census purposes, Hawaii is part of the West Coast, along with the other four states. ''Encyclopædia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinook Salmon
The Chinook salmon (''Oncorhynchus tshawytscha'') is the largest and most valuable species of Oncorhynchus, Pacific salmon. Its common name is derived from the Chinookan peoples. Other vernacular names for the species include king salmon, quinnat salmon, spring salmon, blackmouth, and tyee salmon. The scientific species name is based on the Russian common name ''chavycha'' (чавыча). Chinook are anadromous fish native to the North Pacific Ocean and the river systems of western North America, ranging from California to Alaska, as well as Asian rivers ranging from northern Japan to the Palyavaam River in Arctic northeast Siberia. They have been introduced to other parts of the world, including New Zealand and Patagonia. Introduced Chinook salmon are thriving in Lake Michigan and Michigan's western rivers. A large Chinook is a prized and sought-after catch for a sporting angler. The flesh of the salmon is also highly valued for its dietary nutritional content, which includes h ...

Old-growth Forest
An old-growth forest or primary forest is a forest that has developed over a long period of time without disturbance. Due to this, old-growth forests exhibit unique ecological features. 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. One-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitats 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 heights and diameters, and diverse tree species and classes and sizes of woody debris., the world has of primary forest ...
