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 …show more content…
On the actual day of the fire, the fire planners will again check such conditions as wind and moisture content in the vegetation. The wind direction will determine where the fire is started. Fire crews start the burn with a device called a drip torch. A drip torch is a can of fuel with a flame-carrying wick at the end. When the crewmember tilts the wick toward the ground, a flame streams out and ignites the vegetation. Most of the effort that goes into a prescribed fire is making sure that it is contained in the boundaries set for the fire. Firefighters and fire suppression equipment are near the site if the fire grows out of control (www.nps.gov/wica/fir-why.html, pgs. 1-3).
While not all the effects of prescribed burns are known some are very evident. The first of these common effects is that vegetation and fallen dead material are burned creating an open forest floor. This eliminates any fuel that could contribute to a high intensity fire in the future. When the fire burns the organic material in the forest, nutrient rich ash is left behind. When the first rain comes, the nutrients in the ash dissolve into the soil for the new plants to use. This process is called nutrient recycling. These nutrients left in the soil are a good source of food for the young plants that will begin to grow back. Another outcome of prescribed fire is that new growth begins immediately after the fires have been extinguished. Within
Wildfires need three things called a fire triangle they have fuel source,drywood,plants,oxygen, and a heat source. Every year wildfires burn more than 400 acres. Wildfire can damage homes or buildings and could kill people. Firefighters also fight fire by cutting dead grass.
Today due to controlling forest fires in the past overgrown shrubs now affect trees. Prescribed burnings are conducted to replenish nutrients into the soil while protecting the trees themselves. Prescribed burning is less hot and less intense so that it can be controlled.
Wildfires started as an annual and seasonal occurrence in the south western region of California since the early 1930’s in part
wildfires can be very dangerous to wildlife plants people and buildings the plants help to fuel the fires and that just makes it worse than it would be in a area with a lot less brush to fuel the fire. Wildfires can be very destructive this wild fire burnt 3,000,000 acres of land that is about the size of the state
Brush fires raise particular concerns in the arid desert where they can become large-scale incidents requiring numerous resources and can endanger homes, lives, and personal property. The frequency of brush fire calls when all similar code types are combined total 42 brush fires for the previous 20 months of which 22 were considered working fires. Of the 22 working fires 16 were set intentionally and ruled arson, of which 8 were started by juveniles. There are 3 fires were accidently started by misuse of a heat source (2 campfires and 1 person burning weeds with a propane torch) and
For as long as mankind can conceive, fire has been a remarkable tool to conquer. When controlled, it provides necessary heat, energy, and fuel for a consumer to use; however, when fire goes unattended, it has the potential to become a wholly destructive element. The more western states of America, such as Utah and Colorado, have repeatedly experienced this concept in its most devastating form: wildfires. A wildfire is generally considered to be difficult to control and fast moving, swallowing anything that lay in its path, including forest or human habitat. As human incursion reaches more remote areas in wooded mountains, wildfires pose a serious threat to high-end homes and secluded cabins. The untamed nature of these fires also allows them to creep into subdivisions and endanger more
Virtually everywhere in the United States is affected to one degree of another by wildland fires. Even if a community is not directly involved with the fire itself, chances are that some of its members have gone to help fight wildland fires in other areas of the country by providing manpower, financial support, or other humanitarian aid.
The National Park Service communicates with surrounding areas to help prevent fires. They also have specialists to investigate when a burn ban needs to be in effect, this is all depending on certain reasons and moisture content in the area Angie (2006). Firefighters fight wildfires by depriving them of one or more of the fire trio basics. Traditional methods include water drenching and spraying fire retardants to
Some of the lodge pole pines have cones that are sealed until the intense heat of fire crakes them open and releases the seeds inside. Fires also help stimulate regeneration of sagebrush, aspen, and willows. Sometimes, though, the interaction of fires between these plants can be complicated by other influences such as grazing levels and climate. The above ground part of grasses and forbs may be consumed by the fires, but usually the below ground root systems typically remain unharmed. Commonly, a few years after a fire, these plants increase in productivity.
Forest fires kill many animals and usually destroy a large amount of land. Prescribed burns seem like they would be the best idea, but are they? Their claim to fame is to clear out land in order to decrease the burning space for when an actual forest fire occurs. Yet this may seem like a brilliant idea, but one must look at the negative aspects of controlled burnings. People might have a change of heart when they realize the damages and effects of such an interesting act. Keep in mind that not only is your health involved but even such things as the inconvenience of dealing with a smoky town. It is important to understand that prescribed burns cause severe health problems especially to
It is so horrible to see all of that timber go to waste. Our society depends on timber a lot and we need so much of it to produce so many useful goods. What would happen if we did not have any timber to make homes or proved some type of shelter? We would be lost and have no where to go. Prescribed burns can prevent that great loss of timber and save a lot of trees. Although one purpose of controlled burns is to curve paths for huge forest fires, they are also used to freshen up the area. If an area of trees is left untreated from prescribed burns, the sands are expected to decline in growth (Mitchell 1). Also, to ensure a healthy forest,
Wildfires are a major issue across the world but especially in California. It affects millions of people every year including burning down thousands of houses. California has been in the biggest drought ever recorded the past two years 2015 & 2016. Extreme drought means extreme wildfires because of the lack of water and the very dry environment. Wildfires don’t only affect the environment but all residents, firefighters, firefighter’s families, and community members that are involved with a wildfire. The one way to help with wildfires is to make all people aware on how to prevent wildfires and or be prepared for wildfires. Some interdisciplinary that are involved with wildfires are Public Service and Public Policy, Communication, Emergency
Unattended wildfires have to be attended at all times because a warm breeze can blow the hot ashes and fire out of the pit. Burning debris in fire weather is very dangerous to a community because people are now burning rash and they aren’t putting them out with water and they are unaware of the weather conditions and their surroundings. Arson fires are caused by people who have had bad “moments” with other people around them. Arsonist are people who use accelerants such as gasoline and kerosene, to ignite and directionalize fires. The amount of time for an arsony is 20 years or life. The reason why arsonists set fires is pyromania. Pyromania is an obsessive desire to burn things. There are two types of pyromania: individual and environmental pyromania. Individual pyromania is when one person with this disorder sets something on fire. Environmental pyromania is when multiple disordered people set a certain amount of items on fire and this can be a high risk to others in the environment. Lightning is also a cause of wildfires because lightning is known for always striking the highest point or anything metal. Lightning rods are being used as the highest point for houses so when lightning strikes, it won’t strike anything in the house. Instead, it goes underground and won’t go electrocute anything in the
Fires can either be natural or anthropogenic, which can depend on any situation. A study conducted in 2004 on a wild fire at Voyageurs National Park in Minnesota, suggests that the fire can
Wildfires occur when the climate is moist making trees and shrubs ready to grow and when a dry, hot period occurs a wildfire can occur. Wildfires mostly occur in highly vegetated areas like
