Bowron Clearcut
The Bowron clearcut or the Bowron River clearcut was a forest clearcut near the Bowron River in British Columbia, Canada. It was once considered the largest clearcut in the world. A large timber salvage operation took place in the 1980s in response to a spruce beetle infestation. 15 million cubic meters of wood were harvested. It was known as the "clear-cut you could see from space." Despite its reputation, clearcuts on Cape Breton as well as those found in Deforestation in Brazil, Brazil are larger.[Unknown]. (1992, January 29).The Biggest Clearcut [M]. doi:http://dx.doi.org/10.14288/1.0048367 Background In the 1940s, spruce bark beetle populations began to rise in the area of the Fraser Plateau. This killed many trees that were unable to be salvaged, and may have informed the decision to clearcut the future Bowron River outbreak. All known outbreaks of spruce bark beetle have accumulated in woody debris caused by logging or windthrow. The forest composition of the region was t ...

Clearcut
Clearcutting, clearfelling or clearcut logging is a forestry/logging practice in which most or all trees in an area are uniformly cut down. Along with shelterwood and seed tree harvests, it is used by foresters to create certain types of forest ecosystems and to promote select species that require an abundance of sunlight or grow in large, even-age stands. Clearcutting is a forestry practice that mimics the stand initiation stage of forest succession after a natural disturbance such as stand replacing fire or wind-throw, and is successful for regeneration of fast growing, sun tolerant tree species and wildlife species that readily regenerate in post-stand replacing sites. Logging companies and forest-worker unions in some countries support the practice for scientific, safety and economic reasons, while detractors consider it a form of deforestation that destroys natural habitats and contributes to climate change. Environmentalists, traditional owners, local residents and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prince George, British Columbia
Prince George is a city in British Columbia, Canada, situated at the confluence of the Fraser River, Fraser and Nechako River, Nechako rivers.

Logging In Canada
Rates and causes of deforestation vary from region to region around the world. In 2009, two-thirds of the world's forests were located in just 10 countries: Deforestation in Russia, Russia, Deforestation in Brazil, Brazil, Deforestation in Canada, Canada, Deforestation in the United States, the United States, Deforestation in China, China, Land clearing in Australia, Australia, Deforestation in the Democratic Republic of the Congo, the Democratic Republic of the Congo, Deforestation in Indonesia, Indonesia, Deforestation in India, India, and Peru. Global annual deforestation is estimated to total 13.7 million hectares a year, similar to the area of Greece. Half of the area experiencing deforestation consists of new forests or forest growth. In addition to direct human-induced deforestation, growing forests have also been affected by climate change. The Kyoto protocol, Kyoto Protocol includes an agreement to prevent deforestation, but does not stipulate actions to fulfil it. Af ...

Environmental History Of Canada
Environmental issues in Canada include impacts of climate change, air and water pollution, mining, logging, and the degradation of natural habitats. As one of the world's significant emitters of greenhouse gasses, Canada has the potential to make contributions to curbing climate change with its environmental policies and conservation efforts. Climate change Arctic melting Scientists across the world have already started to notice massive reductions in Canada's Arctic sea ice cover, particularly during the summertime. The shrinking of this ice results in the disruption of the ocean circulation, and changes in climate and weather around the world. The 2019 ''Canada's Changing Climate Report'', written by scientists from institutions around the globe, states that the impacts of climate change on Atlantic Canada will be very diverse. One impact is that the sea ice will become thinner and will also form for much shorter periods of the year. And with less sea ice than the region usual ...

Deforestation In British Columbia
Deforestation in British Columbia has resulted in a net loss of 1.06 million hectares (2.6 million acres) of tree cover between the years 2000 and 2020. More traditional losses have been exacerbated by increased threats from climate change driven fires, increased human activity, and invasive species. The introduction of sustainable forestry efforts such as the Zero Net Deforestation Act seeks to reduce the rate of forest cover loss. In British Columbia, forests cover over 55 million hectares, which is 57.9% of British Columbia's 95 million hectares of land. The forests are mainly composed (over 80%) of coniferous trees, such as pines, spruces and firs. Environmental issues Deforestation has negative impacts on British Columbia's environment and diversity even though it is necessary for population expansion and benefits for the Canadian economy. Carbon emissions and greenhouse gases Carbon emissions from deforestation is an important issue to look at with the increasing prob ...

Humbaba
Humbaba (Ḫumbaba; , ''Ḫumbāba'', with an optional determinative ), originally known as Ḫuwawa in Sumerian (, ''Ḫuwāwa''), was a figure in Mesopotamian mythology. The origin and meaning of his name are unknown. He was portrayed as an anthropomorphic figure comparable to an ogre or giant. He is best known from Sumerian and Akkadian narratives focused on the hero Gilgamesh, including short compositions belonging to the curriculum of scribal schools, various versions of the ''Epic of Gilgamesh'', and several Hurrian and Hittite adaptations. He is invariably portrayed as the inhabitant or guardian of the cedar forest, to which Gilgamesh ventures with his companion Enkidu. The subsequent encounter leads to the death of Humbaba, which provokes the anger of the gods. Humbaba is also attested in other works of Mesopotamian literature. Multiple depictions of him have also been identified, including combat scenes and apotropaic clay heads. It has been suggested that the icono ...

The Epic Of Gilgamesh
The ''Epic of Gilgamesh'' () is an epic from ancient Mesopotamia. The literary history of Gilgamesh begins with five Sumerian poems about Gilgamesh (formerly read as Sumerian "Bilgames"), king of Uruk, some of which may date back to the Third Dynasty of Ur (). These independent stories were later used as source material for a combined epic in Akkadian. The first surviving version of this combined epic, known as the "Old Babylonian" version, dates back to the 18th century BCE and is titled after its incipit, ''Shūtur eli sharrī'' ("Surpassing All Other Kings"). Only a few tablets of it have survived. The later Standard Babylonian version compiled by Sîn-lēqi-unninni dates to somewhere between the 13th to the 10th centuries BCE and bears the incipit ''Sha naqba īmuru'' ("He who Saw the Deep(s)", ). Approximately two-thirds of this longer, twelve-tablet version have been recovered. Some of the best copies were discovered in the library ruins of the 7th-century BCE As ...

Douglas Fir
The Douglas fir (''Pseudotsuga menziesii'') is an evergreen conifer species in the pine family, Pinaceae. It is the tallest tree in the Pinaceae family. It is native to western North America and is also known as Douglas-fir, Douglas spruce, Oregon pine, and Columbian pine. There are three varieties: coast Douglas-fir (''P. menziesii'' var. ''menziesii''), Rocky Mountain Douglas-fir (''P. menziesii'' var. ''glauca'') and Mexican Douglas-fir (''P. menziesii'' var. ''lindleyana''). Despite its common names, it is not a true fir (genus '' Abies''), spruce (genus '' Picea''), or pine (genus ''Pinus''). It is also not a hemlock; the genus name ''Pseudotsuga'' means "false hemlock". Description Douglas-firs are medium-sized to extremely large evergreen trees, tall (although only coast Douglas-firs reach heights near 100 m) and commonly reach in diameter, although trees with diameters of almost exist. The largest coast Douglas-firs regularly live over 500 years, with the ol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lodgepole Pine
''Pinus contorta'', with the common names lodgepole pine and shore pine, and also known as twisted pine, and contorta pine, is a common tree in western North America. It is common near the ocean shore and in dry montane forests to the subalpine, but is rare in lowland rain forests. Like all pines (member species of the genus ''Pinus''), it is an evergreen conifer. Description Depending on subspecies, ''Pinus contorta'' grows as an evergreen shrub or tree. The shrub form is krummholz and is approximately high. The thin and narrow-crowned tree can grow high and achieve up to in diameter at chest height. The ''murrayana'' subspecies is the tallest. The crown is rounded and the top of the tree is flattened. In dense forests, the tree has a slim, conical crown. The formation of twin trees is common in some populations in British Columbia. The elastic branches stand upright or overhang and are difficult to break. The branches are covered with short shoots that are easy to rem ...

Walking Path In Bowron Lake Provincial Park (DSCF3150)
Walking (also known as ambulation) is one of the main gaits of terrestrial locomotion among legged animals. Walking is typically slower than running and other gaits. Walking is defined as an "inverted pendulum" gait in which the body vaults over the stiff limb or limbs with each step. This applies regardless of the usable number of limbs—even arthropods, with six, eight, or more limbs, walk. In humans, walking has health benefits including improved mental health and reduced risk of cardiovascular disease and death. Difference from running The word ''walk'' is descended from the Old English ''wealcan'' 'to roll'. In humans and other bipeds, walking is generally distinguished from running in that only one foot at a time leaves contact with the ground and there is a period of double-support. In contrast, running begins when both feet are off the ground with each step. This distinction has the status of a formal requirement in competitive walking events. For quadrupedal specie ...
