The Effect Of Temperature And Dissolved Oxygen Concentration Associated With Wildfires

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

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

The High Park Fire ignited West of Fort Collins, Colorado on June 9th 2012 and burned over 85,000 acres over the course of containment operations. It eventually became the third largest fire in Colorado history during a highly volatile and active 2012 burn season. Wildfires of this size can have high negative consequences because of the myriad of burn severities throughout the footprint of the fire. Monitoring and inventory protocols need to be established to help determine the effects that fires can have on the landscape and also steer natural resource recovery efforts. This paper will outline a comprehensive monitoring and inventory protocol over the next 30 years from the start of the

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

California is one of the states affected by this problem. Every-time I watch the news, I see that Californians are coming with new technology to deal with this issue. We were experiencing lack of rain in Colorado Springs during the fires more than 2 years ago. Not only we lacked of rain fall, but the carbon release from the fires was way above of what the trees can absorb. The more fires we have in an area, the more carbon capture and release unbalance we have in the area adjacent. The quantitative data shown in your thread is a great method to find out more about this research. Great post!

Massive wildfire ravaged Northern California’s wine country since Sunday night. Wildfires whipped by strong winds have swept through the region, killing at least 10 lives and more than 20000 people are forced to evacuate and flee their homes. This is one of the most destructive wildfire events in the state’s history. More than a dozen wildfires continued to burn across eight counties, destroying 1500 homes and commercial structures according to losses reported up to Tuesday. More death and destruction are expected. Authorities have not said what caused the fires but October is typically the busiest month for wildfire in California. Therefore, they believed that the hot, extremely dry condition in October created the critical fire conditions.

Prescribed burns are utilized throughout the US to prevent devastating wildfires. The use of prescribed burns provides many benefits and few significant deficits to fire-dependent forest ecosystems, therefore, the implementation of controlled burns should continue.

In northern Australia, the fire season usually coincides with progressive drying following the wet season, peaking late in the dry season usually from around August with the start of more severe fire weather, and concluding with the arrival of more regular storm events and rain in late spring and summer (QPWS 2013). Fire weather conditions such as low relative humidity, high winds and a lack of rain all contribute to increased fire danger. Air temperatures of above 30 degrees celsius are also typically conducive to increased fire weather, as are extended periods of higher than average air temperatures. As shown in Figure 3 below, days

The biomass and density of trees surrounding each plot were also recorded. A static chamber method was used to measure the fluxes of the three GHG. The method was carried out using a closed cylindrical chamber equipped with a small fan, and gas concentrations were measured with an infrared, non-dispersive scope. There were other more detailed, accurate methods used as well to be more accurate with exact numbers for the concentrations of each gas. The concentrations of each gas were compared between each location and results are as follows: As the thickness of the active layer increased, all three greenhouse gas emissions increased. Carbon dioxide fluxes increased with time since the last fire, with the 1969 fire area having the highest CO2 emissions, and the 2012 fire area having the lowest CO2 emissions. Methane fluxes had a significant increase in the 1990 fire area, and a lower influx in all other fire areas. Nitrous oxide had a high influx in every fire area except for the 1990 area, where the fluxes were significantly lower. Addressed in the discussion, the authors write about how their results indicate that areas affected by fire will take approximately 50 years to fully recover to their pre-fire conditions. As well, areas with a recent fire had much lower soil moisture than areas with a long time since last

Ecosystems, ever heard of what word? Ever wonder what it is or ever wondered how we are living in one? Ecosystems are a living community of organisms along with their physical environment, functioning as a unit, and for this unit to function there is a need for biodiversity of wildlife including plants and animals. Biodiversity means a variety of living organisms. These ecosystems may be like forests, prairies and oceans as well as many others. Even though they function as a unit, they may be interrupted by disaster, such as tornadoes, floods, wildfires and pollution. For this topic though, it is going to be mainly about forest wildfires, especially in California. Wildfires in California forests can affect animals and plant life. This change

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).

Fires we all know them to be deadly and dangerous, but who would have thought that in Alaska, especially in the Yukon Flats there would be forest fires. These forest fires are causing a major problem with our Earth atmosphere. We can go back to 1939 and see that the fires that are happening right now are exactly the same ones that occurred in the past. The studies are being conducted by Ryan Kelly, a postdoctoral researcher at the University of Illinois and Feng Sheng Hu, a professor of plant biology and geology at the University of Illinois. For their studies, they have used actual fire data from previous studies to come up with a conclusion that in a radius of 2,000 km of the Yukon Flats the fires are way higher than what they were 10,000

With the completion of this field study, there will be adequate information to understand the short term and long term impacts the Rough Fire imposed on water quality in the Sierra Nevada. The final report will be shared with the U.S. Forest Service, specifically with the Pacific Southwest Region (R5), with the goal that there will be more post wildfire projects that aim in restoring water quality back to its original conditions. According to the paper The Science Behind Wildfire Effects on Water Quality, Erosion, there are actions that can be done to improve the water quality from the effects of wildfires. For instance, mulch can be added to stabilize hillslopes and thus prevent further erosion from occurring. Reseeding and the addition of

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).
