Wildfire Effects On Water Quality

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

Since the settlement of the Lake Tahoe Basin people have deforested mountain sides, and killed almost all natural life within the waters. Just as the Lake Tahoe area has felt the

no surprise that wildfires are a huge issue in the western states. Especially on Indian Reservations. Two articles that focus on this issue are called Secretary Zinke Directs Interior Bureaus to Take aggressive Action to Prevent Wildfires, US Department of Interior & Western US Faces Wildfires Explosion by Kieran Cooke, Climate News Network. Both of these articles argue that wildfires shouldn’t become normalized and that something should be done to prevent and/or be better prepared for when wildfires occur. In essence these articles focus primarily on the amount of land burning and the effect it has on vegetation.

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.

Water is probably the most important resource we as people have. Humans can survive without food for several weeks, but without water we would die in less than a week. On a slightly less dramatic note, millions of liters of water are needed every day worldwide for washing, irrigating crops, and cooling industrial processes, not to mention leisure industries such as swimming pools and water-sports centers. Despite our dependence on water, we use it as a dumping ground for all sorts of waste, and do very little to protect the water supplies we have.

As a historically semi-arid environment, California has also suffered heavily from several environmental impacts as a result of the current drought conditions. The first of these is on its forests. The US Forest Service estimates that 12 million trees have died in the past year due to drought; this combined with the drying of forest floor material greatly increases the flammability of the landscape. The result of this is the numerous devastating wildfires that have swept through the state throughout 2015, costing not only wildlife and habitat but also human property (CBS News, 2015) (Lustgarten, et al., 2015) (Google, 2015). Aside from wildfires, the drought and associated loss of habitat is said to be having a negative effect on both flora and fauna due to their contribution to the spread of West Nile Virus, whilst also threatening populations of geese, ducks, salmon and Joshua trees (Lustgarten, et al., 2015) (Beaudry, 2015). Finally, with groundwater contributing up to 50% of stream flow in drought, there is a worry that over usage near the coast could result in irreversible salinization through the drawing in of salt water (USGS, 2016) (Kasler & Reese, 2015).

The Appalachians span over a distance of 1,600 miles, ranging across 14 states, from Newfoundland in the North, to Alabama in the South. The Appalachians are the oldest chain of mountains on the North American continent. With forest, comes forest fires, some natural and some prescribed by humans. In order to reduce the calamitous damage caused by natural wildfires, the technique of prescribed fires is used. This is done by diminishing the amounts of trees, shrubs, and brush in the intended area. By doing this, new native plant growth is encouraged and it helps maintain some plant and animal species that depend on the periodic fires. With this man made force comes numerous effects on vegetation, wildlife, and the human impact.

The Rim Fire of 2013 ravaged the slopes of the Stanislaus National Forest leaving many areas severely burned and unable to recover. Restoration efforts have been made and 56,000 saplings were planted in 2016 in the most severely burned areas; but the forest still has a long way to recovery. Fires are a naturally occurring hazard in the Stanislaus National Forest, and have contributed to the replenishment, control, and sustainability of the forest; but fires of the Rim Fire's intensity are very rare. The Rim Fire destroyed over 277,314 acres of habitat, harmed many mature trees, and ruined the layers of topsoil, and increased erosion and runoff. The devastation of the Rim Fire would not be have been so intense if it weren’t for past fire

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

Sierra Nevada snowpack provide 75 percent to 80 percent of California’s freshwater, and as a result of the increasing temperature, the Sierra snowpack was only 14 percent of normal in February, 2014.3 The lack of water also causes more wildfires.

Water is vital to the survival of man. Settlers fought over it, farmers depend on it, and communities rely on it. Fort Huachuca and Sierra Vista are no exception. Located in one of the driest states in the U.S., they rely on the San Pedro River watershed for water. Barbara Tellman and Diane Hadley’s (1999) book Crossing Boundaries, talks of travelers in the 1800s who were amazed to see cottonwood lined streams of the San Pedro after traveling for days in desert uplands (p.11). Fort Huachuca was established because of the water source at the foot of the Huachuca Mountains, needed by Captain S.M. Whiteside, his troops and their horses (Price, 2003, p31). In 1902 Congress enacted the National Reclamation Act, signed by President Theodore Roosevelt. The Act recognized the importance of water to western development. Sierra Vista continues to grow, the use of ground water increases causing the water table to drop. As the water table drops, more human, plant and animal life are affected. To understand the significance of water in the Sierra Vista/ Fort Huachuca area, it is important to know where the water comes from, why it is so important and how it can be protected. Sierra Vista’s water is not infinite. There may not be enough

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

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).

Anthropogenic climate change is causing hotter and drier conditions across the southwest United States. Decades of fire suppression campaigns have led to an accumulation of ladder fuels within forests across this region. Both of these factors are now contributing to more frequent and more extreme fires in recent years. These catastrophic fires cause significant changes to ground cover along stream corridors. The loss of ground cover significantly increases the amount of sediment entering watersheds, which can alter both temperature and dissolved oxygen levels throughout the system. The purpose of this paper is to examine the changes in water temperature and dissolved oxygen concentration associated with wildfire, how these changes can be controlled, how effective these controls are, and what more can be done.
