Wildfires And Its Effects On Our Environment

In 2016 “there have been more than 4,000 wildfires in California, with well over 300,000 acres of land burned” (Kieran Cooke).

Wildfires occur in the natural landscape, as forests. They tend to caught fire uncontrollably and last for a long period of time. These occurrences are affected by many factors and each factor stimulates the other. Global warming is one of the major factors that affect both the drought and the wildfire. Researchers predict for higher temperatures in the coming years due to a huge increase in greenhouse gas concentration in the air. As a result, forests will catch fire easily because there will be drier and warmer conditions which allow the trees to die. Therefore, there will be an increase in the rate of wildfires.

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.

The rising number of high severity wildfires in California has significant ecological, economic, and health impacts. Many western American forests are adapted to frequent low severity fires. However, the majority of these forests, and particularly the mixed conifer forests of California, are not adapted to high intensity fires and do not possess fire resistance adaptations such as serotinous cones to protect seeds. Consequently, high severity fires have significant negative impacts on California forests, and the absence of low severity fires has considerably altered many fundamental ecosystem processes (Miller et al. 2008). Prior to 1900, low severity fires would burn every 6-15 years. Low severity fires are generally non-lethal, have minimal change to the overstory, and kill mainly small trees. In the past, these fires were started naturally by lightning, or by Native Americans who used low severity fires to manage the forests.

The focus of this lesson will be teaching the students to examine the history of wildland fires and their impact on society in America and in their community. Students will explore different approaches to living with fire and will examine various fire management techniques including prescribed fire, fire suppression, and fire prevention. They will take a closer look at the Copper King Fire in Montana, and will conduct a research project of wildfire history in another state. Students will also gain a better understanding of the role of fire in a particular culture and the importance of wildfire in the ecosystem. They will also understand ways to reduce wildfire risk around their home and community. Furthermore, students will increase their knowledge

Looking further into the impacts of the Rodeo-Chediski fire the trees saw the greatest impact of the fire. Almost 90% of the trees suffered complete crown kill (Ffolliott, 2008). Either some trees had survived with low severity, were harmed, or dead because of the drought and the fire combined. Even though some of the trees that had faced high severity apparently after having seen what trees had survived the fire yet by 2004 two years after the fire they had died (Ffolliott, 2008). The wildfire also impacted the standardization structure, post-fire mortality of trees, and stocking of tree reproduction on the Steamer Ridge Watershed (Ffolliott, 2008). After the fire had finally been contained the density of the forest had been forever changed.

Wildfires have always been a part of our lives on this rock we call Earth. Over the years we have developed tried and true ways to battle and extinguish them, but in the recent past it has become more and more of a problem considering their increase in size and weather patterns. These factors have been termed with a phase every American knows all too well, “Global Warming!” The western half of the United States has had to deal with these fires more than any other area of the country. Of the western half, the state of Colorado has seen its share of some of the worst wildfires. Since the 1970 's the normal number of flames in excess of 1,000 sections of land every year has almost quadrupled in Arizona and Idaho, and has multiplied in

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

The economic cost of wildfires is very expensive. All the help from the firefighters is very costly. The firefighters work hours a day for months depending on how big the fire spreads. All the chemicals and aircrafts they spend on trying to put out the fire adds on to the cost. The houses and the rest of the owner's belongings are lost from the fire and are needed to be rebuilt and repurchased. Millions of dollars is spent on the damage of

The Cedar Fire (2003) was one of the largest and deadliest wildland fires in California history burning nearly 300,000 acres in San Diego County and killing 15, including 1 firefighter. A lost hiker accidently set this fire from survival methods attempted with a flare. It resulted in evacuations of thousands of San Diego residents and destroyed approximately 2400 homes (CALFIRE, 2016). The

According to Merriam-Webster’s Dictionary, Wildfire means “a sweeping and destructive conflagration esp. in a wilderness or a rural area.” Also according to the same dictionary, wilderness means “a tract or region uncultivated and uninhabited by human beings.” Forest Fires happen when there is a drought because branches and twigs die and dry out creating plenty of fuel for a fire. According to the NIFC (National Interagency Fire Center) there are about 105,534 wildfires that occur each year.

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

For instance in United States the relationship between wildfire and climate across the southwest United States involves an interaction between wet and dry cycles that evolves over many seasons and years. The fire–climate relationships identified in areas of Arizona and New Mexico dominated by xerophytic forests show that antecedent climate conditions months to years prior to fire seasons can be as important as the actual fire season conditions. Peak fire season (April, May and June) conditions are climatologically hot and dry across Arizona and New Mexico. Above normal temperatures and below normal precipitation would do little to change already harsh conditions during the spring. Precipitation anomalies in seasons to years prior appear to

The difference between wildfires and megafires is the amount of destruction. Megafires are usually stronger, quicker and burn up to 100,000 acres of land. Regular wildfires only burn up to 70 acres. Climate change can impact the frequency of wildfires because “In a warmer environment, precipitation levels change. This means that dry conditions occur for longer periods in many locations, weakening trees. Making the problem worse, trees rely upon melting snow for moisture. Warmer conditions mean that this snow tends to melt earlier in the season, forcing trees to endure drier soil for longer periods.” (“Wildfires and Climate Change”). In conclusion, the hotter weather forces snow to melt faster off trees, putting them in a drier state for a longer period of time, making them vulnerable to a wildfire. Lastly; to sum up. If humans don’t do anything to prevent climate change, more wildfires and megafires will

Humans have been changing the Western forests' fire system since the settlement by the Europeans and now we are experiencing the consequences of those changes. During the summer of 2002, 6.9 million acres of forests was burnt up in the West (Wildland Fires, 1). This figure is two times the ten year annual average, and it does not look like next summer will be any better (Wildfire Season, 1).
