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..
Why is selective cutting more sustainable than clear cutting?
Selective cutting is more sustainable than clear cutting because in clear cutting the chances of loss of diversity of plant species is more. Also some species native to a region may get extinct by clear cutting. Hence, selective cutting is more sustainable.
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.
What are the pros and cons of clear cutting?
What Are Some Advantages & Disadvantages of Clear Cutting?Pro: Financial Reasons. Clearcutting advocates argue that the method is the most efficient for both harvesting and replanting trees. … Con: Effects on Plant and Wildlife. … Pro: Increased Water Flow. … Con: Loss of Recreation Land. … Pro: Increased Farmland.Apr 23, 2018
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.
What are the disadvantages of shelterwood cutting?
Potential Drawbacks Shelterwood cutting leaves rows of mature trees to provide shade and better dictate the new crop of trees. This leaves the mature trees more vulnerable to storms and the wind. They no longer have the support and shield of nearby trees to help keep them up.
Which forest harvesting technique is most profitable?
clearcuttingThe most economically profitable and the historically most popular timber harvesting technique, clearcutting, has taken a lot of flack in recent years. Like most methods and aspects of forest management, clearcutting can have both a positive and a negative impact.
Does selective cutting increase 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.
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 good?
(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 …
Why is selective cutting expensive?
With selective cutting, only some of the trees in an area of forest are cut down at any one time. … Selective cutting takes longer, is more expensive, and can be dangerous for loggers working in tight spaces, however, it preserves topsoil and does not expose soil to erosion or streams to sedimentation.
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 disadvantages of logging?
Logging can impact climate change by increasing the amount of free carbon dioxide in the atmosphere. Plant life stores carbon dioxide within its tissues. Deforestation often goes hand in hand with fire, which releases this stored carbon dioxide into the air, compounding the greenhouse gas effects.
