Escape Fire
An escape fire is a fire lit to clear an area of vegetation in the face of an approaching wildfire when no escape exists. Approximately 40-percent of all wildfire deaths are caused by such fire entrapments, or what are sometimes called "burnovers". Description Like a backfire, an escape fire works by depriving an approaching primary fire of fuel, so that when the primary fire reaches the point where the escape fire started the primary fire cannot continue, as there is nothing there to burn. Description of the use of an escape fire, in the context of the Yarnell Hill Fire: "They’d use flares to set the brush around them on fire, a technique Wag Dodge, a Montana firefighter, famously used to save his own life on a fire that killed 13 smoke jumpers more than 60 years earlier. It would burn the fuel out around the safety zone and keep the flames farther away from the shelters." In contrast, unlike a controlled burn, backfire, an escape fire does not attempt to control – let alo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction Product (chemistry), products. At a certain point in the combustion reaction, called the ignition point, flames are produced. The ''flame'' is the visible portion of the fire. Flames consist primarily of carbon dioxide, water vapor, oxygen and nitrogen. If hot enough, the gases may become ionized to produce Plasma (physics), plasma. Depending on the substances alight, and any impurities outside, the color of the flame and the fire's Intensity (heat transfer), intensity will be different. Fire in its most common form can result in conflagration, which has the potential to cause physical damage through burning. Fire is an important process that affects ecological systems around the globe. The positive effects of fire include stimulating growth and maintaining various ecological systems. Its negative effects include hazard to life and pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wildfire
A wildfire, forest fire, bushfire, wildland fire or rural fire is an unplanned, uncontrolled and unpredictable 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 fire, prairie fire, vegetation fire, or veld fire. Fire ecology, Some natural forest ecosystems depend on wildfire. Wildfires are distinct from beneficial human usage of wildland fire, called controlled burn, controlled burning, although controlled burns can turn into wildfires. Fossil charcoal indicates that wildfires began soon after the appearance of terrestrial plants approximately 419 million years ago during the Silurian period. Earth's carbon-rich vegetation, seasonally dry climates, atmospheric oxygen, and widespread lightning and volcanic ignitions create favorable conditions for fires. The occurre ...

Yarnell Hill Fire
The Yarnell Hill Fire was a wildfire near Yarnell, Arizona, ignited by dry lightning on June 28, 2013. On June 30, it overran and killed 19 members of the Granite Mountain Hotshots. Just one of the hotshots on the crew survived—he was posted as a lookout on the fire and was not with the others when the fire overtook them. The Yarnell Hill Fire was one of the deadliest U.S. wildfires since the 1991 Oakland Hills fire, which killed 25 people, and the deadliest wildland fire for U.S. firefighters since the 1933 Griffith Park fire, which killed 29 "impromptu" civilian firefighters drafted on short notice to help battle that Los Angeles area fire. Yarnell also killed more firefighters than any incident since September 11 attacks, 9/11. The Yarnell Hill Fire is the List of the deadliest firefighter disasters in the United States, sixth-deadliest American firefighter disaster in history, the deadliest wildfire ever in the state of Arizona, and (at least until 2014) was "the most- ...

Controlled Burn
A controlled or prescribed burn, also known as hazard reduction burning, backfire, swailing, or a burn-off, is a fire set intentionally for purposes of forest management, farming, prairie restoration or greenhouse gas abatement. A controlled burn may also refer to the intentional burning of slash and fuels through burn piles. Fire is a natural part of both forest and grassland ecology and controlled fire can be a tool for foresters. Hazard reduction or controlled burning is conducted during the cooler months to reduce fuel buildup and decrease the likelihood of serious hotter fires. Controlled burning stimulates the germination of some desirable forest trees, and reveals soil mineral layers which increases seedling vitality, thus renewing the forest. Some cones, such as those of lodgepole pine and sequoia, are pyriscent, as well as many chaparral shrubs, meaning they require heat from fire to open cones to disperse seeds. In industrialized countries, controlled burning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grassland
A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures." (Pilot Assessment of Global Ecosystems, 2000) * "A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

James Fenimore Cooper
James Fenimore Cooper (September 15, 1789 – September 14, 1851) was an American writer of the first half of the 19th century, whose historical romances depicting colonist and Indigenous characters from the 17th to the 19th centuries brought him fame and fortune. He lived much of his boyhood and the last fifteen years of life in Cooperstown, New York, which was founded by his father William Cooper (judge), William Cooper on property that he owned. Cooper became a member of the Episcopal Church (United States), Episcopal Church shortly before his death and contributed generously to it. He attended Yale University for three years, where he was a member of the Linonian Society.#Lounsbury, Lounsbury, 1883, pp. 7–8 After a stint on a commercial voyage, Cooper served in the U.S. Navy as a midshipman, where he learned the technology of managing sailing vessels which greatly influenced many of his novels and other writings. The novel that launched his career was ''The Spy (Cooper nov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Prairie
''The Prairie: A Tale'' (1827) is a novel by James Fenimore Cooper, the third novel written by him featuring Natty Bumppo. His fictitious frontier hero Bumppo is never called by his name, but is instead referred to as "the trapper" or "the old man." Chronologically ''The Prairie'' is the fifth and final installment of the ''Leatherstocking Tales'', though it was published before '' The Pathfinder'' (1840) and ''The Deerslayer'' (1841). It depicts Natty in the final year of his life still proving helpful to people in distress on the American frontier. The book frequently references characters and events from the two books previously published in the ''Leatherstocking Tales'' as well as the two which Cooper wouldn't write for more than ten years. Continuity with ''The Last of the Mohicans'' is indicated by the appearance of the grandson of Duncan and Alice Heyward, as well as the noble Pawnee chief Hard Heart, whose name is English for the French nickname for the Delaware, ''le Coeu ...

Mann Gulch Fire
The Mann Gulch fire was a wildfire reported on August 5, 1949, in a gulch located along the upper Missouri River in the Gates of the Mountains Wilderness (then known as the Gates of the Mountains Wild Area), Helena National Forest, in the U.S. state of Montana. A team of 15 smokejumpers parachuted into the area on the afternoon of August 5, 1949, to fight the fire, rendezvousing with a former smokejumper who was employed as a fire guard at the nearby campground. As the team approached the fire to begin fighting it, unexpected high winds caused the fire to suddenly expand, cutting off the men's route and forcing them back uphill. During the next few minutes, a "blow-up" of the fire covered in ten minutes, claiming the lives of 13 firefighters, including 12 of the smokejumpers. Only three of the smokejumpers survived. The fire would continue for five more days before being controlled. The United States Forest Service drew lessons from the tragedy of the Mann Gulch fire by designing ...

Wildfire Suppression
Wildfire suppression is a range of firefighting tactics used to suppress wildfires. Firefighting efforts in wild land areas require different techniques, equipment, and training from the more familiar structure fire fighting found in populated areas. Working in conjunction with specially designed aerial firefighting aircraft, these wildfire-trained crews suppress flames, construct fire lines, and extinguish flames and areas of heat to protect resources and natural wilderness. Wildfire suppression also addresses the issues of the wildland–urban interface, where populated areas border with wild land areas. In the United States and other countries, aggressive wildfire suppression aimed at minimizing fire has contributed to accumulation of fuel loads, increasing the risk of large, catastrophic fires. History Australia Wildland fire, known in Australia as bush fire, has played a major role in Australia due to arid conditions. Notable fire services tasked with wildfire suppres ...
