Driving along the old California logging roads, you see the trees start to thin out and the roads become illuminated. You begin to wonder, what happened to these beautiful trees and why are there only stumps left behind? Out here in the massive trees of California, the effects of humans are becoming even more prominent. With less than 5% left of the tallest trees in the world, and only 2.5% of them protected, the forests are suffering. “Many remaining groves, both protected and unprotected, are threatened by significant alteration of surrounding watersheds from development and logging which can increase the frequency and severity of floods, fires, and sedimentation,” stated D. Olson. Logging has brought in many invasive species including bark beetles, which attack and kill live trees, and are then known as …show more content…
“The debris left behind at logging sights inviting even more diseases and pests.” Logging also compresses the soil. Soil compression restricts root growth and minimizes the amount of nutrients available to vegetation. With root growth restricted, root function becomes minimized. When there are less nutrients available to the plants, they then become more susceptible to diseases. It also decreases the amount of oxygen and water available to the vegetation. With the amount vegetation dying in the forests, there are even more fire hazards littering the forest floor. According to sierraforestlegacy.org, logging operations greatly increase the risk of fire in a forest because of the increase of surface dead fuels and because it is changing the local microclimate. With the microclimates changed, the local conditions become hotter and drier, resulting in even more fire hazards. With the unnatural fire patterns, even more carbon emissions are being released, which is now contributing to global
When people see new construction or a recently paved road, they often do not realize the sacrifice that was made to create these luxuries. Most people pass some form of construction on the way to their jobs or school every day. This simple fact sparks questions regarding what this area looked like before it was inhabited by humans. Illinois forests have undergone drastic changes in the decades since European settlement. Only 31 % of the forest area present in 1820 exists today. (Iverson Pdf) Tearing down trees to build new structures isn’t bad if done in moderation, in some ways with time and good planning its wonderful. However, anyone that hunts or claims to be an outdoorsman will relate to the incomparable feeling experienced when alone in the woods and far from the hustle of the urbanized world.
The gathering of a lot of fuel wood had contributed greatly to deforestation, desertification and other soil erosions. One area that has been decertified is the Sahara desert. Over many years of deforestation and taking of fuel wood, this once a rain forest has become an arid land for heat. When people gather the wood or cut down the tress this leads to soil erosion. The roots from the trees help soil stay in place when there are floods and heavy rain falls. Also trees can help decrease wind speed and not cause sandstorms. In many cases through out Africa, which has low fuel, wood resources there are a lot of sandstorms. The greatly reduce these problems, people should start planting more trees to take the place of all the trees that have been cut down. Trees help us in many ways. With more trees air qualities can be much better. Also by using other resources for fuel can be a good idea to lessen the amount of trees used and cut down.
Each year, 55,000 acres of Northwest forest land succumb to chainsaws to feed the ever-increasing foreign and domestic demands for lumber (Time 21). To profitably satisfy these demands, old-growth trees, those of two hundred years or more, are sought by Northwest logging companies. At this rate, environmentalists believe the unique ecosystem created by old-growth forests is in danger of being destroyed. To protect the old-growth forests and the plants and animals found there, a reduction must be made in the amount of old-growth trees logged each year. Yet reducing the amount of logging in the Pacific Northwest decreases the current number of jobs involved in harvesting the forests and the revenue received by both the companies and the government for their processed logs. To fully understand the current conflict over the old-growth forests, we must look at what each side stands to lose and then suggest a possible balanced sol...
Hills dominate much of San Rafael’s geographical profile. Partially located on a large rock quarry, San Rafael’s jagged edges provide stark contrast with its smooth, rolling hills and the nearby China Camp State Park, an almost unknown escape filled with lush greenery and forests. 10 years ago, both the state park and the surrounding hills were covered with oak trees. Recently however, the disease Sudden Oak Death has posed a serious threat to every oak tree in the area. Forestry officials have been forced to burn out any trees that have been infected with the disease, leaving the skeletons of these once mighty trees to dot the landscape. These reminders of nature’s tr...
Logging in the United States is a very controversial subject. Many people have different opinions on how we should take care of our forests and sometimes the arguments can get heated. Logging needs to be done to protect small western communities from catastrophic wild fires. Logging also gives small communities a way of income. When people think of logging they think of clear cutting which is damaging to the environment, but clear cutting does not happen too much on the national forests. The Forest Service has strict guidelines in which they follow to make sure the forest will stay healthy for years to come. Logging must be done with wildlife, human effects of the forest, and the health of the forest in mind. Logging can ultimately liberate small towns in the forest from fire danger and liberate the towns from having to depend on surrounding communities for a way of income. The forest and animals are also liberated from dense forest which can suffocate animals and plants. The animals are provided with more food with grasses after logging has accrued. Logging if done right is great for the forest and towns that are in the middle of the woods.
Who are the loggers? The loggers are people that are cutting down the rainforest for materials to use for almost anything you want.loggers want all types of wood. Loggers use the trees for many different reasons and purposes.Like paper to write on and,houses to live in,tables,tools,building,doors and so many more different reasons that i can't even name.Loggers don't just cut trees down for any purpose they do it for you.If you don't know trees are more important to you than you think.they put a roof over our head and make paper to write on.Most of this happen because the loggers cut them down so dont think of this as a bad thing all of the time.
The controversy over logging, and more specifically clearcutting, is not a new issue in America. Ever since the 1920's and 1930's, when this nation started to become conscious of conservation, citizens have weighed the consequences of logging. Critics have questioned whether the increase in jobs, tax dollars, and economic growth was worth the destruction of forest lands. Regardless of what they believe today, the logging industry had become so efficient that by the late 1980's nearly 100,000 acres of federal land had been clearcut since the industry began. Logging technology has advanced rapidly in terms of speed, to meet the increasing demands for lumber, paper, and other products derived from trees. This in turn has greatly impacted the environment by severely degrading watersheds, leading to increased soil erosion, the diminution in the quality of drinking water, and the decline of fish stocks, among many other consequences. In this essay I will examine the progression of logging equipment throughout the 19th and 20th centuries and discuss how these changes in technology have not only changed the relationship of those who work in the industry, but also haw this has changed the wider relationship of society and nature.
Environmental issues affect every life on this planet from the smallest parasite to the human race. There are many resources that humans and animal needs to survive; some of the most obvious resources come from the forests. Forests make up a large percentage of the globe. The forests have global implications not just on life but on the quality of it. Trees improve the quality of the air that species breath, determine rainfall and replenish the atmosphere. The wood from the forests are used everyday form many useful resources. Moreover, thinning the forests increases the amount of available light, nutrients and water for the remaining trees. Deforestation (forest thinning) is one of the most critical issues of environmental problems that are occurring today.
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. Wildfires). Destroying homes, crops, towns and of course forests. Yet the effects of these fires can be seen from a negative perspective as well as some positive. Plus there are natural causes as well as manmade that makes these destructive fires erupt and become almost unstoppable in seconds.
Natural factors such as a region’s climate, soils, storm patterns, and the composition of presettlement vegetation influence current forest structure and shape perceptions of desired forest structure (McBride and Jacobs, 1986; Nowak, 1993). The physical development of cities influences the space available for vegetation and its distribution (Sanders 1984). Technological advances in areas such as transportation, air conditioning, and pest control influence attitudes regarding the value of trees, as well as their preservation and management (McPherson and Haip, 1989; McPherson and Luttinger, submitted). Historical data on the development of urban forests can be used with information on current forest structure to better understand key forces of change, current management needs, and future trends in forest health and productivity. As the notion of urban forestry broadens from street tree management to urban ecosystem management, a corresponding need exists for greater information about urban natural resources (McPherson,
Industrial logging is the main cause of forest loss throughout the tropics. It is the starting point of a process leading to the forests' final destruction and substitution by agricultural crops, cattle raising or monoculture tree plantations. These are well known facts supported by more than sufficient evidence.

The single biggest direct cause of tropical deforestation is conversion to cropland and pasture, mostly for subsistence, which is growing crops or raising livestock to meet daily needs. The conversion to agricultural land usually results from multiple direct factors. For example, countries build roads into remote areas to improve overland transportation of goods. The road development itself causes a limited amount of deforestation. But roads also provide entry to previously inaccessible—and often unclaimed—land. Logging, both legal and illegal, often follows road expansion (and in some cases is the reason for the road expansion). When loggers have harvested an area’s valuable timber, they move on. The roads and the logged areas become a magnet for settlers—farmers and ranchers who slash and burn the remaining forest for cropland or cattle pasture, completing the deforestation chain that began with road building. In other cases, forests that have been degraded by logging become fire-prone and are eventually deforested by repeated accidental fires from adjacent farms or pastures.
And in order to keep track of and limit the immense number of forests being cut down every year, the government must take action. The government should monitor illegal logging and deforestation of forests, which in turn negatively affects already fragile environments by initiating soil erosion, loss of species, community disturbances, and carbon emissions into the atmosphere. As was previously stated, soil erosion is a main contributor to the deterioration of forests caused by deforestation and illegal logging. The removal of trees causes the soil underneath to become exposed and thus more vulnerable to the harmful effects of flooding and wind erosion.... ...
With the illegal production’s steady growth rate, the Earth‘s biodiversity has become a victim of widespread damage and ruin. “Illegal logging destroys forests, watersheds, and habitats and negatively affects biodiversity, agriculture, fisheries, and global climate change.” (Colburn, Hitch & Swegle, 2012). Illegal logging has caused mudslides to occur, carbon emissions to become increased, and species to become endangered. In certain areas like Peru, where illegal loggers have all but eradicated the Mahogany tree from existence, loggers are moving their aim to other less known species of trees. These certain trees- Copaoba, Ishpingo, and Capirona- are consid...
