Malibu and Yosemite share similar ecosystem, which encourages wildfires and periodic firestorms. In his book Ecology of Fear, Mike Davis argues that Malibu should burn because wildfires are a part of its history. To illustrate his point, he relates numerous historical events from the first settlement of the region to modern days. Despite the high frequency of wildfires in Malibu, humans have continued to settle there in droves. Those settlers have fought the fires, which has done nothing but augment their intensity. Unlike Malibu, with its populated areas that have been damaged by wildfires, Yosemite benefits greatly from wildfires. Yosemite’s ecosystem has evolved with wildfires; indeed, without wildfires, Yosemite would lose its uniqueness. Also, Yosemite is not as heavily populated as Malibu, so fires in Yosemite would not affect humans to the same degree that they do in Malibu.
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...

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.
Australia is a land of rather extreme weather conditions and widely diverse climates that force the vegetation living there to adapt in many interesting ways. Australia is the driest continent, and biomes such as grasslands and savannas are prime sources of widespread catastrophic fires. The plants that grow in the vast arid and semi-arid regions of Australia are prone to fires simply because of the desert climates that they grow in. High temperatures combined with low fuel moisture contents, little humidity and drying winds that sweep across the landscape encourage many of the plants living in these areas to burst into flames at fairly frequent intervals. Serotinous cones, protective bark, intricate underground recovery systems, unique seed distributions and even the necessity of fire for reproduction are just some of the amazing ways that the major plant families which grow in these fire-prone areas have learned to adapt to their environments.

Current research is being conducted by the National Parks Service to better understand the patterns of invasive plants on the Park, including sagebrush and cheat grass. Yosemite has announced that air quality on their worst days is unlikely to improve until California State’s regulations take effect (“National Parks Service”). More eco-friendly tours and car banning could be cut down in the future to remove some of the tropospheric ozone. Fire awareness is also sweeping through Yosemite, especially in the camping areas, which would cut down wild fires and excess smoke. “In Yellowstone, fires are historically less frequent, but more intense”, this is simply not the case in Yosemite (“PBS”).
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.
For many of us “regular folk”, we dream of visiting California and seeing celebrities or even being one. We see Hollywood as a heaven or even a holy bubble that we all want to be in. This is not true for all, but it is for most. We as a society do not generally think of the negative impacts Hollywood and fame has on an individual. Carrie Fisher, with her wit, humor, and extreme honesty, takes us inside her life and gives us her insight on Hollywood based her upbringing. After going through multiple triumphs, tragedies, and revelations Fisher writes about it all in her book, Wishful Drinking, along with three other novels she has written. Now you see why I used the term “regular folk,” because Fisher is the opposite of a “regular folk.” Even
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.
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.
Redwoods were named for the color of their bark and heartwood. These trees have a high resistance to fungus and diseases due to the high tanin content in the wood. The dense, fibrous bark has an even higher content, and acts as an insulator from periodic fires which have plagued the countryside for centuries. Though these trees are immense, they have delicate foliage. The needles are narrow and sharp-pointed, and combine to form feathery sprays. The cones are an inch long and typically contain fourteen to twenty-four seeds. The older trees offspring sprout form their parents' roots in order to take advantage of the established root system.
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.
Many old-growth forests across the landscape of northern Lower Peninsula of Michigan contain a mixture of tree species rather than a monoculture. Many researchers have put forward ideas to explain the competition and co-existence of tree species in such communities. A theory explaining competition and co-existence between two species is gap regeneration. Gap regeneration is when a gap is created upon death of a plant individual and a new individual, sometimes of the same species as died and sometimes not dependent on environmental heterogeneity, takes its place (Kenneth Lertzman). Canopy gaps during gap regeneration can be explained by either reciprocal replacement or habitat preference . In a reciprocal replacement, seedlings of one species would be found predominately under large trees ...
First, the reading passage mentions that the many trees and vegetation died during the one of the most massive forest fires, Yellow stone, and this national treasure had been destroyed because of this policy. On the contrary, the professor argues that many new plants could germinate and adapt to the new situation in which all tall trees which are similar to barriers and prevent the light penetration; consequently, the forest fires could be become new habitats

Wildfires have been a major issue for many years; with the first one being recorded over four hundred and twenty million years ago the world realized they were dealing with an untamable monster. The effects that forest fires have on nature are by far extreme. Wildfire rips across the landscape tearing through and burning every living parcel in its path. If this occurs to often or burns for an excessive amount of time the natural cycle can be thrown out of balance. This equilibrium allows for the best the regeneration of the area and with this disturbance it may be slowed or even stopped. Along with plant life being thrown out of cycle the effects on nature’s creatures is also a major factor. With the loss of the majority of plant life causes the animal’s key food source is lost and many begin to migrate away from the area and into more adequate ones or some just starve to death. On top of losing a food source the anima...
The Forest fire is occurring very frequently nowadays, reasons for it are a heavy increase in global warming and an increase in temperature.
