Recommended: Effect of wildfires on ecosystems
Wildfires and hard to control and make can cause harm to not only animals but humans too if it spreads far enough. Nonetheless, it's a natural part of the forest cycle. Even though it can be risky, instead of a wildfire, an controlled forest fire can improve the forest and animals life and survival without getting out of hand.
A fire is oddly enough, a natural process in a forest. A fire burns all the waste such as weeds or dead plants and mixes in with the soil renewing and refreshing it. Aside from the improvement of the soil, gasses such as Carbon Dioxide are released into the atmosphere. The release of Carbon is great for plants and their new growing process that will occur. Not only will the plants have a fresh start to grow, they will have a chance to bring up new and a variety of different species into the forest.
Aside from plants, it increases the quality of life for the forest animals as well. In the forest some species strive and overpopulate likewise some struggle and become endangered if not extinct. For those overpopulating species a fire reduces their population while bringing animal diversity or variety of species to the environment. Also with less of the overpopulating

The natural fuels in the forest build up and the fire's intensity becomes even greater as well as spreading faster. Just as a wildfire gets out of control very easily and quickly, there are steps, precautions, and certain weather conditions of which must be planned and prepared for in order to keep a prescribed forest fire in control and safe such as Professor Rick Laven explains in the "Benefits of Prescribed Burning" article. As long as the research and planning is done to ensure the fire will remain in control, the worry for an attempt to fail into disaster is not
The ecological effects of wildfires on Yosemite are among some its greatest benefits. Trees like Bishop Pines and Sequoias have evolved in such a way that their seeds will only open when exposed to high temperatures. The fires also help to clear out dead leaves and weeds, thereby making sunlight accessible to new plants and increasing their chances to germinate (Marder). Wildfires are so essential in areas like Yosemite that over millions of years, plants have developed strategies to be successful in this type of environment. For instance, giant sequoias have developed a thick layer of fire-resistant bark. This bark is “the main explanation for tree survival in intense fires” (Gignoux, Colbert, and Menaut). Fire makes the soil fertile and redistributes the nutrients evenly so that the next generation of trees can cover more space. The fires have helped...
Fires kill plants and trees leaving wildlife without homes and food. Large fires cause lots of smoke and air pollution.
In making the decisions to protect people’s lives from hazards and disasters, evacuations sometimes become necessary. Of course early in the reaction to the incident, or the response phase, this may become a decision for local and state emergency managers. The San Diego, California wildfire which occurred in October 2007 caused a large scale evacuation. This essay is an analysis, and identification of lessons learned from the evacuation incident. As well a plan of personal recommendations and improvements will be made based on information covered in the National Housing strategy, and Robert Stafford Act.
Although fire is linked to human life, as it is essential for survival, not only its use for food, security and warmth, particularly in the extreme cold weather
Policies regarding the handling of wildland fires continue to change and evolve as new information is learned each fire season. Attitudes have changed between complete wildland fire suppression to no suppression at all. We now seem to have reached a balance between the two schools of thought and fall somewhere in the middle.
... them with more abundant and more nutrition vegetation as well as cover and shelter. It seems that the benefit and need for fire in certain environments is very important. So this leaves people to ask the question, “Why don’t we increase the use of prescribed fire?”
As people of the twenty-first century, we are all too familiar with the frequent occurrence of wildfires in our nation’s forests. Each year millions of acres of woodlands are destroyed in brutal scorches. It has been estimated that 190 million acres of rangelands in the United States are highly susceptible to catastrophic fires (www.doi.gov/initiatives/forest.html.). About a third of these high-risk forests are located in California (www.sfgate.com). These uncontrollable blazes not only consume our beautiful forests but also the wildlife, our homes and often the lives of those who fight the wildfires. The frequency of these devastating fires has been increasing over the years. In fact, in the years 2000 and 2002, it has been reported that the United States has faced its worst two years in fifty years for mass destruction fires (www.doi.gov/initiatives/forest.html.). The increased natural fuels buildup coupled with droughts have been a prevailing factor in contributing to our wildfires and unhealthy forests (www.blm.gov/nhp/news/releases/pages/2004/pr040303_forests.html). Due to the severity of these wildfires, several regulations and guidelines have been implemented to save our forests. In fact, the President himself has devised a plan in order to restore our forests and prevent further destruction of our woodlands.
Thousands upon thousands of acres are lost in forest fires every year. We always hear about the dramatic losses caused by forest fires and are often concerned by them. There are so many horrible effects from fires and most of them affect so many people. Studies have shown that out of all of the different methods to decrease fire damage, prescribed burns are the most affective. Many people would argue that they are not as affective because they cause so many health problems. Although that is a very important view and may seem valid, those health issues are not as extreme as one might think. People should look at the majority of the benefits form prescribed burns and they will see how affective and important they are. Prevention is the key to society these days and is definitely an important factor in saving lives. If more lives can be saved as well as land and wildlife, prescribed burns may be the better way to go about forest fires. Although, prescribed burns are better for the environment in order to prevent drastic forest fires, severe damage to timber and extreme death of wildlife; some people feel it affects the health of a firefighter too much and it causes too many long term effects.
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 firefighters; these are concerning carbon monoxide poisoning, visibility issues and health risks that will affect the future.
Once forests began to be viewed as beneficial, it opened up a whole new lifestyle. The forests and nature might have been an evil and scary place, but it was a place filled with resources and opportunity. Settlers began using trees and wood in a plethora of ways. Not only was it used for families own use, many began logging forests as a business; a very profitable business at that. Once wood started being used for beneficial purposes, a snowball effect occurred by the settlers to cut down every tree in sight and turn it into a profit.
Prescribed fires are a well debated topic. While many people support them because they "help prevent" more wildfires, and they are "controlled," I see from a different point of view. There's a reason most building don't allow smoking within a certain distance of the building. Many people don't like it and it can damage their health. Same thing with prescribed fires. They add more pollution to the air we breathe. I know a lot of people support these kinds of fires because the help control fuels, but there are other ways.
Wildfires have been a major issue for many years; with the first one being recorded over four hundred and twenty million years ago the world realized they were dealing with an untamable monster. The effects that forest fires have on nature are by far extreme. Wildfire rips across the landscape tearing through and burning every living parcel in its path. If this occurs to often or burns for an excessive amount of time the natural cycle can be thrown out of balance. This equilibrium allows for the best the regeneration of the area and with this disturbance it may be slowed or even stopped. Along with plant life being thrown out of cycle the effects on nature’s creatures is also a major factor. With the loss of the majority of plant life causes the animal’s key food source is lost and many begin to migrate away from the area and into more adequate ones or some just starve to death. On top of losing a food source the anima...
Obliterating everything in its path, a bushfire is a natural hazard, which can be defined as wild fires in scrublands and or bushlands, especially one that spreads rapidly and is hard to contain. They can be catastrophic, causing severe damage to properties, the environment and even deaths. And as a result there is an ever-increasing need to prepare for the potential impacts of bushfires.
Forests are vital for life and have many important functions. They are home to millions of species and protect soil from erosion. Along with this they produce oxygen which is vital for human life, store carbon dioxide and help control climate. They also provide humans with shelter, food and medicines vital for life.
The Forest fire is occurring very frequently nowadays, reasons for it are a heavy increase in global warming and an increase in temperature.
