A wildfire is any instance of uncontrolled burning in grasslands, brush, or woodlands. Wildfires destroy property and valuable natural resources, and may threaten the lives of people and animals. Wildfires can occur at any time of the year, but usually occur during hot, dry weather. Wildfires are usually signaled by dense smoke which may fill the air for miles around. The National Weather Service, U.S. Forest Service, and State forestry agencies combine to give wildfire probability forecasts. Local radio and television stations broadcast information and warnings on local fire conditions. Wildfires pose an increasing threat to the residential United States. In 1987, 53,000 fires consumed more than two million acres. By October 1988, almost 70,000 fires had claimed more than four million acres. The increase in fires is the result of population growth in rural communities and in the wild land and urban interface. Fire is a powerful, natural phenomenon (www.nps.gov/pub_aff/issues/fire.html, pg.3). Fire has great impact on the people and environment of North America as one saw when in 1988 wildfires broke out all over Yellowstone National Park burning 793,880 acres. For hundreds of years man has suppressed wildfires. The federal government controls fires on federal forestland, and state government controls state forestland. It was believed that by suppressing the fires man ensured a healthy future for the forest. But, as scientists have gathered more information on the effects of fire on forest ecosystems, they have learned that fire exclusion might not have been the best practice for land management. A new technique known as prescribed fire has been used in the last twenty years to reintroduce the natural process of fire back into the forests. While not all the effects of prescribed fire are seen right now, we do know the effects of fire exclusion, and we do know some of the benefits of prescribed fire. Over the past couple of decades, forest management teams

Title : Natural Phenomena: Wildfires
Order : Topical Order
General Purpose : To Inform
Specific Purpose : The acknowledge audience about the effect of the wildfires towards communities and environment health
Central Idea : Although wildfire is a natural disaster, but one of the reason is, comes from human. Wildfires can cause damages to home and others structures. Moreover, wildfires can cause air pollutant that can affect human health. However….
summer 2013 wildfires have been a major problem all over the world. When you think of fires you probably think about all the negative effects, but did you know that in some cases fires can be good? A way that we can help forests is by using a controlled burn or selectively logging. That is how you use a fire positively. That will help the community and the ecosystem. One place I will talk about in specific is Utah.
The first thing I will address is the positive effects that wildfires have on our….
Natural Hazards : Wildfires / Causes of Wildfires
Wildfire Definition : an Uncontrolled fire which breaks out in a Natural
Environment. It may be ‘controlled’ (put out) after some days or weeks – but for a time
it is out of control – and takes place in forests, grasslands or crop fields – not in cities.
Key Terms :
Lightning : Common in summer
when thunderstorms develop. The
biggest single ‘natural’ cause
Volcanic eruptions : lava, ash,
pyroclastic flows can spark….
Wildfires are a very powerful and destructive for the ecosystem surrounding it. However, wildfires have positive aspects too. A wildfire is known as wildland fires, forest fire, vegetation fire, peat fire, bushfire(in Australia) or hill fire across the world. Uncontrolled fire often occur in wildland, but also could occur in houses or agricultural resources. Wildfires could be unnoticed at the beginning, but it could spread quickly igniting trees and houses etc. It could originate in any….
In Australia, wildfires are extremely common. This region is experiencing a high drought. When the air is warm and the land is dry, these wildfires start and does not stop for minutes and hours. It destroys everything in its path including the trees that have adapted overtime to weather. Hundred of trees burn down leaving nothing but ashes. Khan stated, “ Trees like the King Billy Pine and fagus — a beech tree and the only winter-deciduous tree in Australia — could be burned out of their range on….
Wildfires can be very dangerous fires that are likely to burn down an entire forest. They spread very quickly, and they are very damaging and can throw an ecosystem off balance. These roaring fires are very destructive and can cause all lot of harm so it’s important that you take caution. Some of the extreme damage it can cause is not only burn down a forest, but destroy acres of land, that could be someone’s property and home. The highest number of Wildfires that have ever occurred in the U.S….
on wildfires, the issue is that wildfires can be good but there is always one bad thing, its that the animals can die cause of these wildfires. Wildfires are good in natural ways like for example they can clear dead leaves from the floor for new things to grow and it can also clear dead trees or things that are not useful to the trees or to habitats witch is good. I believe that we should continue to have contained wildfires and natural wildfires.
Wildfires provide a slew of associated hazards which require adequate hazard mitigation strategies to protect their communities. First, it is important to examine the human element. Wildfires primarily impact dry vegetation climates, however, most fires are caused by the inappropriate utilization of fire, subsequently causing fires (Smith and Petley, 2013, p. 288). However, wildfires can be also be caused by a more natural means. The natural occurrence of lightning provided an ignition source which….
The current state of wildfires in North Carolina is expanding rather quickly due to the sudden forest fire that commenced. The wildfires have spread through 44,000 acres of land, governor McCrory declared state of emergency in 25 counties. Nearly 16 hundred firefighters have helped to control the severe fire spreading through the piedmont, and mountains. Over 10 million dollars in damage has been caused by the wildfires. On saturday, the federal emergency management association approved the request….
On June 30, 2013 a wildfire began that proved to be the most deadly wildfire in over 50 years. The wildfire was started by a strike of lightning just outside the city of Yarnell, AZ. The Prescott Fire Department 's elite group of firefighters, who were called Granite Mountain Hotshots, were called in to contain the fire. While attempting to contain the fire around Yarnell, the winds changed directions, and picked up speed. This caused the fire to circle around the firefighters, cutting….
