Selective logging only cuts down certain trees (valuable trees), whereas clear-cutting cuts down all of the trees .
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.
Is clear-cutting or selective cutting better?
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 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 the difference between clear-cutting and selective cutting of forests 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.
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.”
What are the disadvantages 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 the process of clear-cutting?
Clear-cutting is a method of harvesting and regenerating trees in which all trees are cleared from a site and a new, even-age stand of timber is grown . ... Many conservation and citizen groups object to clear-cutting any forest, citing soil and water degradation, unsightly landscapes, and other damages.
Why is selective cutting less damaging to the environment than clear-cutting what problems does it still have?
What problems does clear cutting still have? selective cutting removes single trees or a relatively small number if trees from the larger forest thus making it less damaging to the environment by taking out less trees. Clear cutting removes all the trees within an area and can shake up an ecosystem.
Is selective cutting good?
When practiced correctly, selective cutting has the following benefits. 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.
Where is selective cutting used?
Heavy machinery is used, leaving sections between the strips uncut, especially among lakes and rivers to reduce soil and limit wind erosion. Selective cutting means to go in and harvest only a limited amount of trees that meet a certain criteria. This usually happens in multi-species forests .
Is shelterwood cutting expensive?
Although primarily used in even-aged stands, it may also be used in some uneven-aged stands when even-aged regeneration is desired. Shelterwood harvesting is usually the most difficult and costly during the initial cut when the poorest quality trees are removed .
What happens to animals when an area is clear cut?
Wild animals, insects and plants are killed by large clear cuts . After the trees are gone, groundcover plants wither in the sun and parched soils. Most die. Soil animals, bacteria and fungi, vital to tree growth and health, overheat, shrivel and die.
What is an alternative to clear cutting?
As an alternative to clearcutting, selection management is the method of cutting only individual or small groups of trees in a healthy natural forest at periodic intervals, such as every ten years.
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. All of the below would result n an area that was recently clear-cut except.
