Redwood Creek (Humboldt County)
Redwood Creek ( Yurok: '' 'O'rekw 'We-Roy '' ) is a river in Humboldt County, California. The river's headwaters are in the Coast Range at about and it flows roughly northwest until it empties into the Pacific Ocean near the small town of Orick, the only development in the - watershed. Course Redwood Creek begins near Board Camp Mountain in the Coast Ranges near Dinsmores. The stream's headwaters lie at about above sea level, in a network of small unnamed streams along the north sides of a ridge abutting the Mad River valley to the south. It flows north through a deep forested valley, receiving many small tributaries including Minor and Lacks creeks from the right. About downstream of the source, the creek crosses under State Route 299. Slightly less than from the mouth, the river passes the southern boundary of Redwood National Park. It then receives Bridge Creek from the left, before winding through several groves of Sequoia sempervirens, more commonly known as r ...

Roosevelt Elk
The Roosevelt elk (''Cervus canadensis roosevelti)'', also known commonly as the Olympic elk and Roosevelt's wapiti, is the largest of the four surviving subspecies of elk ('' Cervus canadensis'') in North America by body mass. Mature bulls weigh from . with very rare large bulls weighing more. Its geographic range includes temperate rainforests of the Pacific Northwest including parts of northern California. It was introduced to Alaska's Afognak, Kodiak, and Raspberry Islands in 1928 and reintroduced to British Columbia's Sunshine Coast from Vancouver Island in 1986. Naming and protection In December 1897, mammalogist C. Hart Merriam named the subspecies after his friend Theodore Roosevelt, then Assistant Secretary of the US Navy. The desire to protect the Roosevelt elk was one of the primary forces behind the establishment of the Mount Olympus National Monument in 1909 by President Theodore Roosevelt. Later in 1937, President Franklin D. Roosevelt visited the region an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Forest
A forest is an ecosystem characterized by a dense ecological community, community of 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 (biology), 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 (FRA), Global Forest Resources Assessment 2020'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest Terrestrial ecosystem, terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the Tropical forest, trop ...

Logging
Logging is the process of cutting, processing, and moving trees to a location for transport. It may include skidder, skidding, on-site processing, and loading of trees or trunk (botany), logs onto logging truck, trucksSociety of American Foresters, 1998. Dictionary of Forestry. or flatcar#Skeleton car, skeleton cars. In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. In common usage, however, the term may cover a range of forestry or silviculture activities. Logging is the beginning of a supply chain that provides raw material for many products societies worldwide use for housing, construction, energy, and consumer paper products. Logging systems are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sediment
Sediment is a solid material that is transported to a new location where it is deposited. It occurs naturally and, through the processes of weathering and erosion, is broken down and subsequently sediment transport, transported by the action of wind, water, or ice or by the force of gravity acting on the particles. For example, sand and silt can be carried in suspension (chemistry), suspension in river water and on reaching the sea bed deposited by sedimentation; if buried, they may eventually become sandstone and siltstone (sedimentary rocks) through lithification. Sediments are most often transported by water (fluvial, fluvial processes), but also wind (aeolian processes) and glaciers. Beach sands and stream channel, river channel deposits are examples of fluvial transport and deposition (geology), deposition, though sediment also often settles out of slow-moving or standing water in lakes and oceans. Desert sand dunes and loess are examples of aeolian transport and deposition. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rare Species
A rare species is a group of organisms that are very uncommon, scarce, or infrequently encountered. This designation may be applied to either a plant or animal taxon, and is distinct from the term ''endangered species, endangered'' or ''threatened species, threatened.'' Designation of a rare species may be made by an official body, such as a national government, state, or province. The term more commonly appears without reference to specific criteria. The International Union for Conservation of Nature does not normally make such designations, but may use the term in scientific discussion. Rarity rests on a specific species being represented by a small number of organisms worldwide, usually fewer than 10,000. However, a species having a very narrow Endemic (ecology), endemic range or Habitat fragmentation, fragmented habitat also influences the concept. Almost 75% of known species can be classified as "rare". Rare species are species with small populations. Many will move into the ...

Redwood Creek
Sequoioideae, commonly referred to as redwoods, is a subfamily of coniferous trees within the family Cupressaceae, that range in the northern hemisphere. It includes the largest and tallest trees in the world. The trees in the subfamily are amongst the most notable trees in the world and are common ornamental trees. The subfamily reached its peak of diversity during the early Cenozoic. Description The three redwood subfamily genera are '' Sequoia'' from coastal California and Oregon, ''Sequoiadendron'' from California's Sierra Nevada, and ''Metasequoia'' in China. The redwood subfamily contains the largest and tallest trees in the world. These trees can live for thousands of years. Threats include logging, fire suppression, and burl poaching. Only two of the genera, ''Sequoia'' and ''Sequoiadendron'', are known for massive trees. Trees of ''Metasequoia'', from the single living species ''Metasequoia glyptostroboides'', are deciduous, grow much smaller (although are still large ...

Redwood National And State Parks
The Redwood National and State Parks (RNSP) are a complex of one United States national park and three California state parks located along the coast of northern California. The combined RNSP contain Redwood National Park, Del Norte Coast Redwoods State Park, Jedediah Smith Redwoods State Park, and Prairie Creek Redwoods State Park. The parks' 139,000 acres (560 km2) preserve 45 percent of all remaining old-growth coast redwood forests. Located in Del Norte and Humboldt counties, the four parks protect the endangered coast redwood (''Sequoia sempervirens'')—the tallest, among the oldest, and one of the most massive tree species on Earth—which thrives in the humid temperate rainforest. The park region is highly seismically active and prone to tsunamis. The parks preserve 37 miles (60 km) of pristine coastline, indigenous flora, fauna, grassland prairie, cultural resources, waterways, as well as threatened animal species, such as the Chinook salmon, northern spotted owl, ...
