Why is selective cutting better than clear-cutting?

With selective logging, the largest trees are taken which means a loss in the seed source. The trees remaining often shade seedlings (small plants) that need sunlight to grow and eventually become trees. Clear-cutting is better when the soil already contains seeds.

What is the advantage of selective cutting over clear-cutting?

After harvesting hardwood timber, the remaining trees will reseed naturally. It would be hard to clearcut an old growth forest and then try to reseed or plant seedlings. Recreating the diversity in the forest would be nearly impossible. Selective cutting allows the trees to take care of the new growth naturally.

Is clear-cutting better than selective cutting?

Clear-cutting and shelterwood systems typically lead to an even-aged structure. Selective cutting typically leads to an uneven-age structure. Using seed trees can lead to an even-age structure for the new stand if regeneration occurs quickly; if regeneration occurs gradually, the result can be an uneven aged stand.

What is a better method than clear-cutting?

Selective logging is a more ecologically sustainable practice than clear-cutting, which entails removing all trees at the same time. The idea behind selective logging is to maintain an uneven or all-aged forest of trees varying not only in age, but in size and species as well.

What is an disadvantage of clear-cutting?

Cons Of Clear-Cutting. Destroys forest ecosystems, depriving wildlife of natural habitats and decreasing biodiversity. Still, fauna can return to the area when the forest is renewed. Increases the risks of soil erosion.

Logging: Selective vs Clear Cut

What are the advantages of selective logging?

Selective logging is selective because loggers choose only wood that is highly valued, such as mahogany. Clear-cutting is not selective. 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.

What are the pros and cons of clear-cutting?

What is the difference between clear-cutting and selective cutting quizlet?

Clear-cutting can damage the environment and the soil where the trees were cut. The soil is exposed to wind and rain. In selective cutting the loggers must move the heavy equipment and logs around the remaining trees in the forest.

Why is clear-cutting unsustainable?

The act of clear cutting is not only damaging to the structure and function of the forest, but in particularly erosion-prone areas the loss of root structures significantly affects water quality, and leads to the loss and fragmentation of nutrient rich soil, creating a lack of regenerative biomass and reduces primary ...

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.

Does either clear-cutting or selective cutting provide more economic value?

From a commercial or agricultural perspective, clear-cutting can be more economical and less time-intensive than scrutiny of the forest area tree by tree followed by a more selective cutting of trees.

Does selective cutting cause erosion?

(Pros) Advantages of selective-cutting: • Supports more wildlife by keeping their ecosystems intact • They build up tolerance and resistance to disease and pests • Carbon dioxide that is stored by the trees will regenerate (regrow) faster • Helps the forest grow back faster • Reduces fire hazards and minimizes soil ...

Where is selective cutting used?

Selection cutting, also known as selection system, is the silvicultural practice of harvesting trees in a way that moves a forest stand towards an uneven-aged or all-aged condition, or 'structure'.

Is selective cutting sustainable?

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.

Why is clear-cutting trees harmful?

Water And Soil

Mass removal of trees increases the soil erosion by water runoff. Excessive runoff muddies waterways and harms aquatic life. Removal of trees shading streams raises the water temperature and lowers its oxygen levels to the detriment of fish and other aquatic fauna.

Does selective cutting provide wildlife habitat?

Managing a forest by correct selective thinning results in dramatic wildlife habitat improvement. Selective thinning opens the canopy, which allows sunlight to hit the forest floor. Depending on landowner objectives, wildlife openings (small clearings) can also be created.

What is the most sustainable method of harvesting trees?

Selective Logging Is The Most Sustainable Method Of Harvesting Trees. Although there are many benefits of using selective logging as the most sustainable method of harvesting trees, there are also many disadvantages.

Why is clearcutting bad for animals?

Large clearcuts create drastic ground level climate changes that few forest-dwelling wildlife species can tolerate. Shady, moist, comparatively cool environments under forests are suddenly open to direct sunlight, higher air temperatures and the drying effects of winds.

Why is clear-cutting the worst type of logging for the environment?

The biggest problem people see with clearcutting is habitat disturbance. When a large group of trees is felled all at once, birds, rodents, and other animals that used the trees for shelter or food are displaced and need to flee to other areas.

What is the difference between clear-cutting and selective cutting list some pros and cons of each?

Lists some pros and cons of each. Clear cutting refers to the removal of a section of trees at once. Selective cutting refers to the removal or a single or very few trees in a forest. Clear cutting is more efficient and cost-effective, while selective cutting is less harmful to a forest ecosystem.

What is the difference between clear-cutting and strip cutting?

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 selection cutting quizlet?

Selective cutting. Harvesting only mature trees of certain species and size; usually more expensive then clear-cutting but it is less disruptive for wildlife and often better for forest regeneration. Clear cutting. Forestry/logging practice in which most or all trees in a harvest area are cut down. Strip cutting.

What are some pros to clear-cutting?

Clearcutting pros: It creates wide, open spaces with lots of sun exposure. This allows the most sunlight to reach tree seedlings that require full-sun conditions to thrive. Clearcutting also creates forest clearings that are habitat for some species of songbirds, deer and elk.

How does clear-cutting affect water quality?

Clearcutting can send heavier loads of sediments and nutrients downriver, harming water quality and fish and decreasing storage capacity (as water volume is displaced by sediments).

Is selective logging good or 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.”
