4.0 Results 4.1 Total Fires Burned
There were 9323 separate forest fires that occurred from the start of 2005 till the end of 2014. which resulted in a total area of 12,356,894.538 hectares of burned forest and affected land.
4.2 Fires per-year and Area Burned per-year
The year that saw the most forest fires between 2005 and 2014 in the western provinces was 2010 with 1348 fires. As well as having the most fires 2010 also saw the greatest amount of surface area burned, with 2,429,289.909 hectares of land being burned. The year with the least forest fires was 2005 seeing a total of 478 fires and 372,473.408 hectares burned. However despite the low number of fires 2005 did not have the least surface area burned. Out of the ten years studied

31 percent of forest fires were caused by human actions. 14 percent of fires were had unknown origins or were prescribed burns and re-burns. According to Gillett ,N.P paper: “Detecting the effect of climate change on Canadian forest fires”, forest fires in Canada ignited by lightning strikes account for 88% of all area burned. My findings have found that this statistic is also true for the western provinces of Canada because 88.7 percent of all area burned by forest fires in the study were caused by lightning strikes. Based on the fact that a large proportion of forest fires in Canada are caused by lightning strikes it should be possible to get an understanding of where forest fires are likely to be ignited by thunder when looking at weather forecasting and previous precipitation in the area. The amount of damage done to the 29 populated places in the past ten years would have experienced varying amounts of damage. Depending on how much of the town was affected an the types of urban developments that were present at the time of the fire. The number of people affected also depends on the size of the town and the area burned by the fire. Fires burning near residential neighbourhoods would result in many people being evacuated from their homes. In July of 2015, 10,000 people had to be removed from their homes in northern Saskatchewan due to increased forest fire activity. (CBC News- …show more content…
A greater study sample may have resulted in the discovery of more trends regarding the increase in forest fires over time likely because of climate change. The change in climate that has occurred since the earliest recorded forest fire in the data set in 1917 till 2014, is likely much more significant then the changes from 2005 to 2014. However data inconsistencies in the accuracy of data recored in the past would have to be taken into account in this circumstance as well as increased computer processing lengths due to larger amounts of data. Further studies could be done comparing temperature and forest fire data over a period of time. For example average temperature data for the western provinces, over a ten year period compared to the number area of burnt land. A study like this may have made it possible to more definitively understand how climate change is effecting the severity and number of forest fires in Canada. However to complete such a project, would have require large amounts of data and time that is unavailable to myself.

Fire plays a huge role in natural forests. The let it burn policy allows natural fires to burn unless, they threaten people, property, or endangered species. This policy allows the years and years of kindling that has fallen and piled up on the forest floor to burn up in smaller fires, instead of having huge devastating fire like the ones that burning for months in 1910 and 1988. When the west was first settled, forests were thinned by lumber companies that logged the trees and burned the logging debris, and by ranchers looking to increase pasture land. The last herder coming out of the mountains would set a fire to ensure good forage for the next year.
“On one side we see men of some years disheartened and retired from productive exertion. On the other hand, we see places open for younger men” (“Political Economy of the Fire”). After the devastating fire, one hundred thousand people were left without a home.
The United States Department of agriculture Forest Service investigation report on the thirty mile fire.
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.
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 City of Detroit, Michigan, seems to be a city on the decline in America. Job prospects some of the lowest in the country and one of the only cities to be shrinking, rather than growing. There are a lot of problems Detroit is facing, one of them is there incidence rate for fires. Detroit is the number one city in America for house fires, not to mention their high rate of fires in the many vacant buildings throughout the city. There are many socioeconomic factors with the city that make the incident rates rise, and response less effective.
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.
Ten million California residents who lived closely from the major fault lines could have been endangered in many extreme ways. (House, 56). A tragic thing was that after the earthquake a multitudes of fire followed right after. The situation led to the water mains being destroyed and the firefighter being left with no water to settle the growing fire which continued blazing. The bay water was planned on putting all of the dure out but it was to far in distance to be able to transport it (Earthquake of 1906, 2). The firefighters who were putting out the fire were either surrounded or being burned by the fire that was blazing in all directions (San Francisco Earthquake, 2). A resident who was present during the event mention that he/she saw men and women standing in a corner of a building praying, one person who became delirious by the horrific ways that were surrounding him while crying and screaming at the top of his lungs “the Lord sent it, the Lord”. Someone also mentioned that they experience themselves seeing Stones fall from the sky and crushing people to death. Reporters say there were 100 cannons going off (San Francisco Earthquake, 3). People who lived fifty miles away from the fire was able to “read the newspaper at
It is so sad to see the horror of forest fires and how they corrupt our beautiful land. So much damage comes out of what started so small. At least 603 square miles of land were burned in the early stages of the Arizona fire only a couple of years ago (BBC 2). In a Colorado fire 2.3 million acres had been burned (BBC 3). That land could have been saved if the use of prescribed burns had been in the area.
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.
The release of the hazardous material or exposure to the fire that ensues results in the need to evacuate 25 or more people
Human beings cause most wildfires, directly or indirectly. In the United States lightning, the only truly natural cause is responsible for less than 10% of all such fires. In the West, lightning is the primary cause, with smoking (cigarettes, matches, and such) the second most frequent. Combined they account for 50 to 75% of all wildfires. In the “13 southern states (Virginia to Texas) the primary cause is arson; this combined with smoking and debris burning makes up 75% of all wildfires” (Perry, 1994). The other causes of wildfires are machine use and campfires. Machine use includes railroads, logging, sawmills, and other operations using equip...
This paper is the model study that I have chosen to guide my research question and improve upon its current work. This research study looks at the relationship between wildfire extent and severity, and annual streamflow distribution and timing in the Pacific Northwest. Attention was paid to changes in temperature and precipitation for its influence on snow accumulation and therefore snow melt. The rivers included in the study get the majority of their water from snowmelt and groundwater discharge, which can be influenced by wildfire as well as climate; furthermore, changes in climate can influence wildfire extent and severity. Satellite imagery was used to determine burned areas and magnitude of change in overstory vegetation. Principle components
Fire at any level can be devastating, yet the effects that wildfires have on every worldwide country really has left its mark on the land. As written by world renowned wild fire spokesperson Smokey the Bear, “Every year, wildfires sweeps through parts of the United States setting wilderness and homes ablaze. On average these raging infernos destroy about four to five million acres of land a year. But in 2012, wildfire burned more than 9.3 million acres, an area about the size of Massachusetts and Connecticut combined” (U.S. Wildfires). Destroying homes, crops, towns and of course forests. Yet the effects of these fires can be seen from a negative perspective as well as some positive. Plus there are natural causes as well as manmade that makes these destructive fires erupt and become almost unstoppable in seconds.
The Forest fire is occurring very frequently nowadays, reasons for it are a heavy increase in global warming and an increase in temperature.
