Selective cutting allows ecosystems to support more wildlife than clear cutting and allows forests to retain some of their resistance to disease and pests. In addition, studies show that carbon uptake levels will quickly recuperate if selective cutting is done properly.
for instance, What is an example of selective cutting?
The best example of selective cutting is. loggers cut small groups of intermediate or mature trees, resulting in less erosion and loss of nutrients on the hillside.
significantly, Why is selective cutting bad?
“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.”
also How is selective cutting done?
Selective cutting is the cutting down of selected trees in a forest so that growth of other trees is not affected. This is done according to criteria regarding minimum tree size for harvesting, specifications of the number, spacing and size classes of residual trees per area, and allowable cut.
Is Strip cutting better than selective cutting? According to NASA, clear cutting is much more damaging to a tropical rain forest because when all of the trees are removed, the soil loses its nutrients and becomes barren (NASA, 1998). However, according to Ashton, in some cases, it is better to clear-cut a forest than to selectively log it.

What is meant by selective cutting?
Selective cutting is the cutting down of selected trees in a forest so that growth of other trees is not affected. This is done according to criteria regarding minimum tree size for harvesting, specifications of the number, spacing and size classes of residual trees per area, and allowable cut.
What is selective cutting pros and cons?
Some of the disadvantages are that some species may not regenerate quickly, and thinning the forest may lead to increased damage from ice, storms or fires. One of the biggest advantages of selective cutting is that the overall ecological impact on the forest is reduced.
What are the disadvantages of clear-cutting?
Clearcutting cons:
- They look bad. Until the newly planted trees “green up” a hillside, a clearcut is not considered appealing to the general public.
- Habitat disturbance. Clearcutting alters the habitat where trees once stood, and forest wildlife is displaced into new areas.
- Increased stream flow.
What are the advantages and disadvantages of clear-cutting and selective harvesting?
Clear-cutting is usually quicker and cheaper than selective cutting. It may also be safer for the loggers. Clear-cutting can damage the environment and the soil where the trees were cut. The soil is exposed to wind and rain.
What is selective logging and how is it beneficial?
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.
Does selective cutting increase biodiversity?
Selective logging reduces biodiversity, disrupts Amazon ecosystems: study. Reduced-impact logging, also called selective logging, which gained popularity in the 1990s, aims to balance biodiversity impacts with global demand for timber by extracting fewer trees.

Whats the definition of clear cutting?
: the removal of all the trees in an area of forest Long considered a “trash tree” by the timber industry, the number of Pacific yews has been drastically reduced—perhaps halved—by clear-cutting, the logging practice that totally strips a targeted area.—
What is forestry cutting?
Forest cutting, broadly defined here as human activities that remove trees for timber or for converting forestlands into other land uses, is a major anthropogenic disturbance that affects terrestrial carbon (C) storage and fluxes from local to global scales1,2,3,4,5.
Why do environmentalists prefer the process of selective cutting to clear cutting?
Selective Cutting Harvest Method
This process allows for better yield and productivity over several decades. Each year provides trees for harvest, rather than having to wait a minimum of sixty years after a clear cut.
How does clear cutting affect human health?
But deforestation is having another worrisome effect: an increase in the spread of life-threatening diseases such as malaria and dengue fever. For a host of ecological reasons, the loss of forest can act as an incubator for insect-borne and other infectious diseases that afflict humans.
Is clear cutting beneficial?
Clearcuts can be beneficial to wildlife.
Clearcutting increases the biological diversity of the forest, which enhances the habitat for a variety of wildlife. Some species of wildlife actually thrive better in brushy thickets of seedlings and small saplings.
What is happening with clear cutting?
Clearcutting disturbs soils, wetlands, and peatlands, releasing their vast carbon stores, and diminishes the boreal forest’s ability to sequester carbon from the atmosphere.
Why is cut clear?
The principal objective of clearcutting is to regenerate the forest with healthier trees, not to harvest timber. Timber harvesting is a secondary objective. … Clearcutting is especially useful in regenerat- ing species of trees whose seedlings cannot thrive in the shade of a forest understory.
Why is selective logging good for the environment?
Selective logging and replanting,
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. … This is because a felled tree can damage other trees as it falls to the ground once felled.
What are the advantages of reforestation?
- Reduces carbon dioxide in air: Reforestation increases number of plants , thus more carbon dioxide gets absorbed by those plants and the air quality improves.
- Reforestation prevents soil erosion: The roots of trees holds the soil in place thus preventing the erosion and preventing water pollution.
How does selective cutting promote biodiversity?
Selective cutting reduces crowding, encourages growth of younger trees, maintains an uneven-aged stand of tress of different species, and allows natural regeneration from surrounding trees.
What is a problem related to clear cutting?
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 …
