What is a wildfire or a forest fire?
Wildfire, also called forest, bush or vegetation fire, can be described as any uncontrolled and non-prescribed combustion or burning of plants in a natural setting such as a forest, grassland, brush land or tundra, which consumes the natural fuels and spreads based on environmental conditions (e.g., wind, topography).
What are the positive effects of a forest fire?
• One of the biggest positive effects of wildfire is that it helps decrease disease insects. In fact, more trees are killed every year by insects than forest fires. A low intensity forest fire actually helps the forest in its struggle against infestation, which could even cause a bigger forest fire later.

How do you spell forest fires?
“Forest fires.” Merriam-Webster.com Thesaurus, Merriam-Webster, https://www.merriam-webster.com/thesaurus/forest%20fires.
What is forest fire?
The forest fire is the burning of tropical, temperate and boreal forest either by natural fire or man-made fire and is related to land clearing and deforestation. Natural forest fire includes an unplanned burning of forest due to lightning, while human-induced forest fire results from the unauthorized burning practice of forests for attaining farmland. In spite of low commitment of boreal forest in worldwide biomass burning emission, there is 10-folds increase in the extent of boreal forest burning in recent year. The burning of forests destroys an important sink for atmospheric carbon dioxide. Usually, forest burning is widely practiced especially in Central and South America for converting large scale moist tropical forest to rangeland and agriculture, arson negligence and for hunting purpose. Forest burning is another important route for diminishing the catastrophic forest fire risk.
Why are forest fires more frequent?
Forest fires are likely to become more frequent as a consequence of predicted climate changes, as already shown in the Mediterranean area ( Moriondo et al., 2006 ).
How do forest fires affect soil?
The most pronounced impact of forest fires on soil properties is the reduction of infiltration rates due to water repellency. This reduced infiltration not only increases the amount of overland flow and thus soil erosion, but may further reduce the availability of soil water for plants, especially in semiarid regions.
How long does it take for a forest fire to be managed?
Forest fires are considered socially and economically unwelcome, and the burned areas are mandatorily managed within just 2 years of their formation. 2 Management consists of removing partially or fully burned trees and nearly immediate replanting of new tree seedlings ( Kunt, 1967 ).
What is forest fire prediction?

Is forest fire a problem in Europe?
Forest fires (the term used in Europe to designate the unwanted fires burning forests and wild lands) constitute a serious problem throughout Europe. Although there exists a sharp gradient from the South to the North, in terms of fire regime (e.g., contributing and causing factors, fire frequency and area burned, fire behavior), no country is exempt. All face growing risk from increasing population density, creeping urban sprawl from incursion into the wildland urban interface (WUI), and from changes in land-use patterns that conflict with societal and ecological protection. Changing climatic and weather conditions are exacerbating these problems. This chapter discusses this complex phenomenon in Europe and highlights the challenges to managing forest fire risk in ways that reconcile social and economic development, environmental concerns, and living with forest fires in a sustainable and dynamic equilibrium.

What is a wildfire?
Wildfires. Encyclopedic Entry. Vocabulary. A wildfire is an uncontrolled fire that burns in the wildland vegetation, often in rural areas. Wildfires can burn in forests, grasslands, savannas, and other ecosystems, and have been doing so for hundreds of millions of years. They are not limited to a particular continent or environment.
How do fires help the forest?
By clearing scrub and underbrush, fires can make way for new grasses , herbs, and shrubs that provide food and habitat for animals and birds. At a low intensity, flames can clean up debris and underbrush on the forest floor, add nutrients to the soil, and open up space to let sunlight through to the ground.
How do wildfires start?
Wildfires can start with a natural occurrence—such as a lightning strike—or a human-made spark. However, it is often the weather conditions that determine how much a wildfire grows. Wind, high temperatures, and little rainfall can all leave trees, shrubs, fallen leaves, and limbs dried out and primed to fuel a fire.

What are the three categories of land for fuel reduction?
The Forest Service and Interior have identified three categories of land for fuels reduction: (1) lands with excess fuels buildup, (2) lands in the wildland-urban interface where federal lands surround or are adjacent to urban development and communities, and (3) lands where vegetation grows rapidly and requires regular maintenance treatments to prevent excess fuels buildup.
Where are ponderosa pine forests?
Some ponderosa pine forests were historically characterized by mixed fire regimes, although the extent and ecological relationships of these mixed regimes are yet to be determined. It appears that mixed regimes were commonly associated with ponderosa pine growing east of the Continental Divide, and also with some forests west of the Divide, especially those on steep slopes and on relatively moist sites. The most compelling evidence for a large area of mixed fire regime comes from the Black Hills of South Dakota (Brown and Sieg 1996; Gartner and Thompson 1973; Shinneman and Baker 1997) and the Front Range of the Rocky Mountains in Colorado (Kaufmann 1998; Laven and others 1980). Many of the ponderosa pine stands in the Black Hills and nearby areas of northeastern Wyoming and southeastern Montana develop dense patches of pine regeneration after fire, which become thickets of small stagnant trees, susceptible to stand- replacing fire. Intervening areas with more open stocking presumably were more likely to underburn in the frequent fires of the presettlement era. Factors contributing to a mixed fire regime in ponderosa pine probably include relatively moist sites that tended to produce pine thickets soon after a fire, areas frequently exposed to high winds during the burning season, steep topography, and stands killed by bark beetle epidemics.
How do firefighting forces deal with wildfires?
Such a force may attack a fire directly by spraying water, beating out flames, and removing vegetation at the edge of the fire to contain it behind a fire line.
What are the conditions that affect wildfires?
A discussion of high-tech wildfire management in Victoria, Australia. Fire danger in a wildland setting varies with weather conditions: drought, heat, and wind participate in drying out the timber or other fuel, making it easier to ignite. Once a fire is burning, drought, heat, and wind all increase its intensity.
What is prescribed fire?
Prescribed fires, in which controlled fires are intentionally set to decrease the fuels in a given area and to promote the health of fire-adapted ecosystems, can be used to prevent or mitigate wildfires. Aircraft were first used in fighting wildland fires in California in 1919.
What are flash fuels?
Dried grass, leaves, and light branches are considered flash fuels; they ignite readily, and fire spreads quickly in them, often generating enough heat to ignite heavier fuels such as tree stumps, heavy limbs, and the organic matter of the forest floor.

What are the causes of wildfires?
The most common direct human causes of wildfire ignition include arson, discarded cigarettes, power-lines arcs (as detected by arc mapping ), and sparks from equipment . Ignition of wildland fires via contact with hot rifle-bullet fragments is also possible under the right conditions. Wildfires can also be started in communities experiencing shifting cultivation, where land is cleared quickly and farmed until the soil loses fertility, and slash and burn clearing. Forested areas cleared by logging encourage the dominance of flammable grasses, and abandoned logging roads overgrown by vegetation may act as fire corridors. Annual grassland fires in southern Vietnam stem in part from the destruction of forested areas by US military herbicides, explosives, and mechanical land-clearing and -burning operations during the Vietnam War.
How does wildfire modeling work?
Wildfire modeling is concerned with numerical simulation of wildfires in order to comprehend and predict fire behavior. Wildfire modeling aims to aid wildfire suppression, increase the safety of firefighters and the public, and minimize damage. Using computational science, wildfire modeling involves the statistical analysis of past fire events to predict spotting risks and front behavior. Various wildfire propagation models have been proposed in the past, including simple ellipses and egg- and fan-shaped models. Early attempts to determine wildfire behavior assumed terrain and vegetation uniformity. However, the exact behavior of a wildfire's front is dependent on a variety of factors, including wind speed and slope steepness. Modern growth models utilize a combination of past ellipsoidal descriptions and Huygens' Principle to simulate fire growth as a continuously expanding polygon. Extreme value theory may also be used to predict the size of large wildfires. However, large fires that exceed suppression capabilities are often regarded as statistical outliers in standard analyses, even though fire policies are more influenced by large wildfires than by small fires.
How do wildfires affect humans?
Wildfires can cause damage to property and human life, although naturally occurring wildfires may have beneficial effects on native vegetation, animals, and ecosystems that have evolved with fire. Wildfire behavior and severity result from a combination of factors such as available fuels, physical setting, and weather.
