Research Components of the Strategy Biological Considerations If we are to understand the biological appropriateness of any silvicultural system,we must increase our knowledge of the complex structure and function of ecosystems and how they respond to different silvicultural treatments.

Clear-cutting is when every single marketable tree is cut down from a selected area. Forestry companies prefer clear-cutting because it is the cheapest and most efficient way of harvesting timber. It is much easier to move logs and equipment from a bare area than from among standing trees.
Clear-cutting enables forest operators to get the most out of a forest for the lowest cost. In Ontario, clear-cuts routinely exceed hectares and are sometimes even as large as 10, hectares — this is roughly the size of football fields put together!
This administrative tool has enabled the government to violate the spirit of its own regulations. Effects of Large Clear-Cuts on Woodland Caribou The Woodland Caribou is a threatened species which relies on intact forests, free of human development, for its survival.
One of the ways the Ontario government justifies large clear-cuts is based on the assumption that large disturbances are better for Woodland Caribou. The Ministry of Natural Resources MNR argues that the only way to save habitat for Caribou is to concentrate cutting and road building in one area of the forest, so that the rest can be left alone.
This means that massive clear-cuts are created so that the province can continue to reach its timber targets, while supposedly managing for Caribou. However, as the Ministry of Natural Resources has admitted, this caribou management strategy is an experiment. There is no evidence that it will actually help preserve Caribou.
In fact, studies show that the only way to guarantee that caribou will survive in Ontario is to stop cutting in their habitat.
Logging companies also justify large clear-cuts on the grounds that it emulates the disturbances that historically have been caused by forest fires.
They suggest that clear-cuts removes tree canopies, thus allowing other tree species to get the sunlight they need to flourish.
Clear Cut Logging and Other Options Essay - Clear Cut Logging and Other Options Have you ever awakened on a beautiful sunny morning in the Southwest planning on going for a hike in the Cascade Mountains, but when you arrive at your destination there are only stumps. This is the result of clear-cut logging. The choice of clearcutting by forest owners is much dependent upon their objectives. If that objective is for maximum timber production, clearcutting can be financially efficient with lower costs for timber harvesting than other tree harvesting schwenkreis.comutting has also proven successful for regenerating stands of certain tree species without . Logging is an on-site process which involves the cutting, skidding, and loading of trees or logs onto trucks. A skidder or bulldozer is often used in the logging operations which pulls the trees that have already been cut and then transport them from the cutting forest to a landing.
However scientific evidence shows that the benefits associated with natural fires are not present in clear-cuts. For example, many trees release seeds when they are exposed to high temperatures — this ensures regeneration of the forest after the fire is over.
In addition, when leaves and woody debris burn, extra nutrients are produced which is absorbed into the soil. This further encourages new growth. Clear-cutting removes seed sources as well as natural debris that would be left over from a fire. Clear-cutting also requires the construction of roads, which fragments habitat and increases the risk of invasive species.
Clear-cutting may be profitable for logging companies, but it has enormous ecological and social costs. Ecological Costs of Clear-Cutting Clear-cutting is devastating for forest ecosystems.
It causes global warming, drought, habitat destruction, and a dramatic loss of biodiversity. Mature forests store carbon. When a large area is deforested, hundreds of miles of roots systems are destroyed.
This can lead to flooding in some areas and drought in others. Many species rely on intact forests to provide shelter and food.This method still has problems intrinsic with any kind of deforestation and selective logging also introduces new environmental problems.
Tree harvesters need to build roads into the forests to remove the timber (Vandermeer and Perfecto, ). Clear-cut logging is the practice of harvesting all the trees in a specifically marked area. Another logging method is a selective cut which is the harvesting of some trees to open the canopy so the remaining trees can grow faster.
The Oregon Forest Resources Institute describes clearcuts as areas of forest where nearly all the trees are cut down to stumps during a single logging operation. Regulatory legislation in the United States requires that buffer zones be left intact around streams, lakes and other waterways, and the harvested area must be replanted.
Clear-cutting is when every single marketable tree is cut down from a selected area.
Forestry companies prefer clear-cutting because it is the cheapest and most efficient way of harvesting timber. It is much easier to move logs and equipment from a bare area than from among standing trees. Growth responses - The degree and type of growth response that crop tree and other species exhibit following partial cutting.
Re-establishment research - The response of plants and animals to changes in the environment, and the requirements for forest regeneration.
Clear-cutting is a controversial practice that is widely applied in forests managed for wood production in many parts of the world. This paper aims to provide an objective synthesis of the ecological effects of clear-cutting as a basis for more informed discussion of its merits and disadvantages.
