Fire Trail
A fire trail is a rural road built specifically for the purpose of access for "fire management purposes" including building containment lines and backburning operations. The term is part of the vocabulary of Australian bushfire control and may also sometimes be known as a ''fireroad'' in US terminology. A fire trail may act as part of a ''control line'' or fire break but a fire trail in itself does not constitute a fire break. In California, where "fire trail" is the preferred term, it frequently refers to the unpaved roads built for wildfire control on undeveloped urban hills and foothills rather than those in rural regions. Local residents have been known to use them for hiking. As fire trails provide access to otherwise remote areas, they suffer from adverse effects including: illegal activities, erosion, noise pollution Noise pollution, or sound pollution, is the propagation of noise or sound with potential harmful effects on humans and animals. The source of outdoor no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Controlled Burn
A controlled burn or prescribed burn (Rx burn) is the practice of intentionally setting a fire to change the assemblage of vegetation and decaying material in a landscape. The purpose could be for forest management, ecological restoration, land clearing or wildfire fuel management. Controlled burns may also be referred to as hazard reduction burning'', ''backfire'', ''swailing or a burn-off. Controlled burns are conducted during the cooler months to reduce fuel buildup and decrease the likelihood of more dangerous, hotter fires. Controlled burning stimulates the germination of some trees and reveals soil mineral layers which increases seedling vitality. In grasslands, controlled burns shift the species assemblage to primarily native grassland species. Some seeds, such as those of lodgepole pine, sequoia and many chaparral shrubs are pyriscent, meaning heat from fire causes the cone or woody husk to open and disperse seeds. Fire is a natural part of both forest and grass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bushfire
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] |
Firebreak
A firebreak or double track (also called a fire line, fuel break, fireroad and firetrail in Australia) is a gap in vegetation or other combustible material that acts as a barrier to slow or stop the progress of a bushfire or wildfire. A firebreak may occur naturally where there is an absence of vegetation or "fuel", such as a river, lake or canyon. Firebreaks may also be man-made, and many of these also serve as roads, such as logging roads, four-wheel drive trails, secondary roads, or highways. Overview In the construction of a firebreak, the primary goal is to remove deadwood and undergrowth down to mineral soil. Various methods may be used to accomplish this initially and to maintain this condition. Ideally, the firebreak will be constructed and maintained according to the established practices of sustainable forestry and fire protection engineering, also known as best management practices (BMP). The general goals are to maximize the effectiveness of the firebreak at slowin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California
California () is a U.S. state, state in the Western United States that lies on the West Coast of the United States, Pacific Coast. It borders Oregon to the north, Nevada and Arizona to the east, and shares Mexico–United States border, an international border with the Mexico, Mexican state of Baja California to the south. With almost 40million residents across an area of , it is the List of states and territories of the United States by population, largest state by population and List of U.S. states and territories by area, third-largest by area. Prior to European colonization of the Americas, European colonization, California was one of the most culturally and linguistically diverse areas in pre-Columbian North America. European exploration in the 16th and 17th centuries led to the colonization by the Spanish Empire. The area became a part of Mexico in 1821, following Mexican War of Independence, its successful war for independence, but Mexican Cession, was ceded to the U ...

Noise Pollution
Noise pollution, or sound pollution, is the propagation of noise or sound with potential harmful effects on humans and animals. The source of outdoor noise worldwide is mainly caused by machines, transport and propagation systems.Senate Public Works Committee. ''Noise Pollution and Abatement Act of 1972''. S. Rep. No. 1160, 92nd Congress. 2nd session Poor urban planning may give rise to noise disintegration or pollution, side-by-side industrial, and residential buildings can result in noise pollution in the residential areas. Some of the main sources of noise in residential areas include loud music, transportation (traffic, rail, airplanes, etc.), lawn care maintenance, construction, electrical generators, wind turbines, explosions, and people. Documented problems associated with noise in urban environments go back as far as ancient Rome. Research suggests that noise pollution in the United States is the highest in low-income and racial minority neighborhoods, and noise pollut ...

Bicentennial National Trail
The Bicentennial National Trail (BNT), originally known as the National Horse Trail, is one of the longest multi-use, non-motorised, self-reliant trails in the world, stretching 5,330 kilometres from Cooktown, Queensland, Cooktown, Queensland, through New South Wales and the Australian Capital Territory to Healesville, Victoria, Healesville, 60 km north-east of Melbourne. This trail runs the length of the rugged Great Dividing Range through national parks, private property and alongside wilderness areas. The BNT follows old coach roads, stock routes, brumby tracks, rivers and fire trails. It was originally intended for horses, but is these days promoted also for cycling and walking, though it is not yet entirely suited to these two activities. History The trail was initiated and planned by the Australian Trail Horse Riders Association. The Association spent many years planning and negotiating a route that linked up the Muster (livestock), mustering, brumby tracks, pack hors ...

Bushfires In Australia
Bushfires in Australia are a widespread and regular occurrence that have contributed significantly to shaping the nature of the continent over millions of years. Eastern Australia is one of the most fire-prone regions of the world, and its predominant eucalyptus forests have evolved to thrive on the phenomenon of bushfire. However, the fires can cause significant property damage and loss of both human and animal life. Bushfires have killed approximately 800 people in Australia since 1851, and billions of animals. The most destructive fires are usually preceded by extreme high temperatures, low relative humidity and strong winds, which combine to create ideal conditions for the rapid spread of fire. Severe fire storms are often named according to the day on which they peaked, including the five most deadly blazes: Black Saturday bushfires, Black Saturday 2009 in Victoria (Australia), Victoria (173 people killed, 2,000 homes lost); Ash Wednesday bushfires, Ash Wednesday 1983 in ...
