What are advantages of selective logging?

While selective logging is invasive, it does leave wildlife habitats intact, helping maintain the diversity of the forest. Also, leaving trees standing keeps the forest looking natural while contributing to reduced runoff of delicate topsoil and the minimizing of silting of nearby streams and rivers.

What is a disadvantage of selective logging?

Harmful to Trees

Selective logging is harmful not only to the trees that are cut down, but to the ones near them. It is estimated that for each tree that is logged, 30 others are harmed on average. One reason is that when a tree is cut down, the machinery that is used to log it can seriously damage the nearby trees.

What are the positives and negatives of selective logging?

Selective logging is more sustainable than clear-cutting because other trees and plants do survive in the logging process and over time can allow the forest to recover. However, it does have major drawbacks. Although single trees are felled because they are valuable, other trees can be damaged in the process.

What are the negative effects of selective cutting?

“Selective logging, unless it is practiced at very low harvest intensities, can significantly reduce the biomass of a tropical forest for many decades, seriously diminishing aboveground carbon storage capacity, and create opportunities for weeds and vines to spread and slow down the ecological succession.”

What are the disadvantages of logging?

Negative Effects

If managed improperly, logging can have serious environmental impacts. Logging potentially removes habitat for birds and other wildlife that use trees for cover, nesting habitat, or food. Owls, for example, prefer older trees with a larger diameter for nest cavities.

Is selective logging good?

Conclusion. Our study demonstrates that selective logging is a good management technique from an EMF perspective, and thus provide us with potential guidelines to improve forest management in P. yunnanensis forests in this region.

How does selective logging affect the environment?

Although selective logging has a far less impact on forest processes than deforestation, selectively logged sites experience higher rates of forest fires, tree fall, changes in microclimate, soil compaction and erosion, among other ecological impacts on biodiversity and ecosystem functioning.

What is the effect of selective logging on the composition of a forest community?

The researchers found that selective logging drastically changed the composition of the forest. In logged areas, there were far fewer species that depended on animals, such as birds, for dispersal; whereas there were more species dispersed by abiotic forces (non-living actors) such as wind.

What are the disadvantages of forest management?

  • It destroys the habitat of animals and birds.
  • It causes floods and fires.
  • It causes green house gases build-up.
  • It can limit the supply of wood or timber.
  • It can affect the discovery of new herbal medicines.
  • It can eradicate forests for good.

How does selective logging protect the rainforest?

Logging and replanting – selective logging of mature trees ensures that the rainforest canopy is preserved. This method allows the forest to recover because the younger trees gain more space and sunlight to grow. Planned and controlled logging ensures that for every tree logged another is planted.

Why might selective logging be preferable to clear-cutting?

Why might selective logging be considered preferable to clear cutting? it opens up small spaces for light penetration, which allows existing saplings to grow rapidly and fill in the gaps.

How does selective logging improve biodiversity?

Sparing unlogged forests avoids the rapid initial loss of species that occurs with selective logging and could help maintain higher levels of biodiversity, overall, by protecting vital ecosystem functions like decomposition and seed dispersal.

What is selective logging and what is its relationship to the selection system?

The term selective logging is still used today by members of the public to describe any harvesting practice that does not clearcut, but rather leaves a significant number of leave-trees. Many foresters resist the use of this term as a synonym for the selection system, or any form of forest management.

What is a benefit of logging in the Amazon rainforest quizlet?

Loggers often clear-cut whole patches of rainforest, which leads to deforestation. Loggers often argue that a benefit of logging in the Amazon rainforest is that it- Improves Brazil’s economy by increasing the number of jobs in the forest industry.

How does logging affect the rainforest?

Commercial logging companies cut down trees for timber, which is mostly sold to developed countries. In most cases, large areas of forest are destroyed just to remove a few highly valued trees. The effect of this devastation has lasting consequences: heavy machinery compacts soil and makes it more vulnerable to erosion.

What is selective logging?

Selective logging—the practice of removing one or two trees and leaving the rest intact—is often considered a sustainable alternative to clear-cutting, in which a large swath of forest is cut down, leaving little behind except wood debris and a denuded landscape.

What does selective harvesting do?

Selective harvesting applies to forest types that have the capability of regenerating under their own shade. In northern Maine, this refers to northern hardwoods that are composed of sugar maple, beech, and yellow birch. It also refers to softwood species such as balsam fir, spruce, hemlock, and cedar.

What is the goal of selective harvesting?

Selection cutting is a harvesting method designed to create an uneven-aged or all-aged stand structure by harvesting single trees or small groups of trees. It is believed that this has ecological benefits, including increased carbon sequestration, as well as producing a more constant flow of marketable timber.

Why is clearcutting bad?

Clearcutting can destroy an area’s ecological integrity in a number of ways, including: the destruction of buffer zones which reduce the severity of flooding by absorbing and holding water; the immediate removal of forest canopy, which destroys the habitat for many rainforest-dependent insects and bacteria; the removal …

What is the difference between Clear felling and selective logging?

Clear cutting means most – or all – of the trees in a given area are cut down. In selective cutting, only selected trees are cut, leaving the rest of the stand intact.

What is a selective management system?

The Selective Management System (SMS), adopted in peninsular Malaysia, involves the selection of a management regime to optimize not only the objectives of efficient and economic harvesting, utilization, reforestation and sustained yield but, more importantly, to ensure that forest development is biologically, …

Is logging bad for the environment?

Logging removes large trees that normally fall into streams and provide shelter and thermal cover, raises water temperatures and pH, and degrades the chemical and ecological conditions and food webs that fish need to survive.
