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...

- Malibu has been burning ever since it’s been known to mankind. The geographic condition along with fierce Santa Ana wind has made it the perfect burning zone. Yosemite is prone to fire because of its natural condition but not to the extent like Malibu. Malibu has been inhabited for more than a century. Malibu is a place where people went to settle down because of the natural beauty. Mountains along with pacific shoreline are the perfect dream location for many reality businesses. All these natural beauties and the addition of hot and dry weather came with a dangerous problem; which is nothing but fire: a fire which is intensified exponentially by the wind of Santa Ana....

- Imagine a scenic, wild landscape with animals that roam freely, cascading waterfalls, and mountains that seem to scrape the pale blue sky. This is what one thinks when first hearing the name Yosemite National Park. Unfortunately, the reality is completely opposite. Yosemite is now under a federally regulated Class 1 area under the Clean Air Act, which is equivalent to the pollution of Los Angeles (“National Parks Service”). It is a sad comparison to the past John Muir, who first documented Yosemite Valley, to today’s reality.... [tags: Yosemite Pollution]

- 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.... [tags: wildfires, forest fires]

- Ever heard of the "Finagle's corollary to Murphy's Law" that states that, "Anything that can go wrong, willa -- at the worst possible moment?" In our world of more than 7 billion people who reside on the planet Earth, natural disasters are a big part of our lives, some more than others. Of the seven main natural phenomena that result in disaster (Hurricanes, Earthquakes, Floods, Tsunamis, Volcanic Eruptions, Landslides) wildfires can be one of deadliest. A wildfires are uncontrolled fires, which is why they are so dangerous.... [tags: Natural Disasters, Earthquakes, Tornados]

- The purpose of this report is to analyze the current trend of wildfires in the United States and its severity and demonstrate how remotely piloted can help mitigate this at higher rates by recommending to the target audience that use of UAVs be put into law. With the current rate of devastating droughts throughout the country there couldn’t be a better time to recommend a use of technology that seems to be the way of the future. This report will cover how UAVs can be used for surveillance and reconnaissance in fire hunting, how UAVs are used in fire hunting, and mainly cover the need and potential benefits of using these as a tool....

- Malibu Fires Human beings are able to adapt to almost any environment, unfortunately sometimes we take advantage of our natural surroundings. We find ourselves amidst a struggle between our lifestyles and nature. Although we affect nature profoundly with our activities, we in turn are shaped by nature's potent forces. Nature can be brutal to humans, but we must remember that it merely is following its course. As a result, we must learn to coexist with it. Fire is a naturally occurring phenomenon which humans have learned to deal with throughout history.... [tags: essays research papers]

- Dame in Yosemite State Park In the late 1800’s and early 1900’s, a heated debate ensued over the building of a dam in the Hetchy Hetchy Valley in Yosemite State Park. The debate was between the naturalists of the area and the city engineers. I shall explore not only the debate prior to the building of the dam but also its affects on the population since its completion. Being a nature lover myself, I can easily sympathize with the people who wanted to preserve the natural beauty Yosemite, but in light of the facts, I feel that the dam was not only necessary but an overall benefit to the citizens of the surrounding area....

- Malibu Boat’s, which is located in Loudon, Tennessee, has been a manufacturer in recreational towboats, since 1982. Six friends, who all loved and practically lived for waterskiing, decided they wanted to start building their own ski boats in a small shop in Merced, California. Robert Alkema started up the new organization and chose the company’s name, “Malibu Boats”. At his age he was still young enough where he thought there were no obstacles that could get in his way and didn't think his plan could ever fail him.... [tags: towboats, waterskiing, waterboarding]

- Ecological Restoration of Forests and Fires One of the most predominate ecosystems is the forest community. Covering about one-fourth of the land area on Earth, forests consist mainly of trees and other woody vegetation, growing closely together. The trees can be large and densely packed, as they are in the coastal forests of the Pacific Northwest, or they can be relatively small and sparsely scattered, as they are in the dry tropical forests of sub-Saharan Africa. Forests are complex ecosystems that also include “soils and decaying organic matter, fungi and bacteria, herbs and shrubs, vines and lichens, ferns and mosses, insects and spiders, reptiles and amphibians, birds and mammals, and...

- Montana Wildfires HELENA, Mont. (AP) - Beleaguered firefighters in Montana enjoyed something of a lull in their battle against dozens of wildfires, but a new blaze near Yellowstone National Park forced the evacuation of up to 150 homes. And a firestorm in a remote Idaho forest destroyed most of the buildings at a guest ranch, and another guest ranch was ordered evacuated. There were concerns the entire town of Red Lodge, a resort community near Yellowstone in south-central Montana, might have to be evacuated in the face of the blaze.... [tags: Papers]
