Which method of tree harvesting favors slow growing trees that are shade tolerant clear cutting Shelterwood none of the above? Answer Expert Verified. Your answer is clear cutting .
Which tree harvesting method promotes the growth of younger trees by selectively cutting mature trees over a period of 10 years?
Shelterwood is a silvicultural method of regenerating new forest stands by harvesting all mature trees in an area in a series of 2 or more cuts occurring within 10-20 years.
What is the problem with selective cutting the most mature trees in a forest?
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.
Does reforestation always occur as a result of human intervention?
Reforestation always occurs as a result of human intervention . Where is the carbon taken in by plants during photosynthesis stored? ... They emit more carbon than they take in.
What are the methods of regeneration?
Introduction. There are two possible methods of forest stand establishment, namely natural and artificial regeneration . The process of natural regeneration involves the renewal of forests by means of self-sown seeds, root suckers, or coppicing.
What often replaces trees once they have been clear cut?
The trees are then replanted and clear-cut again in a regular cycle. ... In this approach, which is sometimes called industrial forestry, a simplified tree plantation replaces a biologically diverse old-growth or second-growth forest.
Why is selective cutting bad?
Selective logging is causing long-term changes to tropical forests in Africa by facilitating the growth of weeds and vines, which reduces plant diversity and diminishes carbon storage, reports a new paper published in the journal Ecological Research.
Is selective cutting better than clear-cutting?
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.
When animals feed off of land faster than the plants can regrow?
When animals feed off of land faster than the plants can regrow, the land is depleted .
How do you encourage reforestation?
- Increase the amount of forested land through reforestation.
- Increase density of existing forests at a stand and landscape scale.
- Expand the use of forest products that sustainably replace fossil-fuel emissions.
- Reduce carbon emissions caused by deforestation and degradation.
What is the purpose of reforestation?
Restoring various habitats :
The importance of reforestation is not only limited to the environment but also helps in preserving wildlife. Reforestation has the potential to restore various habitats and save many lives. Endangered species of plants can also be revived by reforestation process.
What are some examples of reforestation?

What is the most common regeneration method used today?
In water treatment, the two most common salts used for regenerating cation and anion water softeners are sodium chloride (NaCl) and potassium chloride (KCl) . Sodium chloride is less expensive and more abundant than potassium chloride, which is why it is the preferred regenerate in almost all applications.
How is natural regeneration done?
Natural regeneration is the process by which woodlands are restocked by trees that develop from seeds that fall and germinate in situ . For most of the last two or three centuries foresters have restocked and created woodlands by using transplants grown in nurseries.
What is regeneration of trees?
Regeneration by planting and seeding: The act of establishing a forest stand (e.g. plantation) or re-establishing a forest stand by artificial means, either by planting of seedlings or by scattering seed. The material used may be of indigenous or introduced origin.
When all trees in a large area are removed this is called?
Clearcutting, clearfelling or clearcut logging is a forestry/logging practice in which most or all trees in an area are uniformly cut down.
