“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 selective cutting?
(Cons) Disadvantages of selective-cutting: •
Expensive and time-consuming • Some species will not regenerate (regrow) as fast
• More exposure to weather damage such as ice, storms, and fires • Lots of stumps and other tree debris left behind • Removes genetically superior trees, whose seed is needed to keep forest …
Is selective cutting bad?
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 is selective cutting what are the pros and cons?
Selective cutting
allows ecosystems to support more wildlife than clear cutting and allows forests to retain some of their resistance to disease and pests
. … 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.
Why is selective logging bad?
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.
Why is selective cutting better than 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.
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 are the pros of selective cutting?
- Removes trees that are low quality while they are young.
- Removes some of the profitable mature growth.
- Allows more light to penetrate the upper story of growth. …
- Allows trees that are shade intolerant to receive more light.
What does selective cutting do?
Using stocking models derived from the study of old growth forests, selection cutting, also known as ‘selection system’, or ‘selection silviculture’,
manages the establishment, continued growth and final harvest of multiple age classes (usually three, but 5 or even 10 are possible)
of trees within a stand.
What is the environmental impact 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 cons of clear-cutting?
- 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 is selective logging advantages and disadvantages?
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 negatives of selective logging and replanting?
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 benefits of selective logging?
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.
What does selective logging look like?
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.
Is selective logging profitable?
However, the selective logging process is
more than just harvesting the profitable trees from the forest
. … Although selective thinning doesn’t present the large-scale initial profit of other methods such as clear cutting, it can create a more productive and better yielding forest that provides a harvest every season.
