Other examples include allowing young trees time to mature, the planting of trees to expand forestlands, and the creation of protected forests. Use Reduced-Impact Logging Techniques Reduced-impact techniques allow loggers to fell and extract trees in a manner that reduces damage to other trees in the stand. This approach also minimizes erosion, waste, and carbon emissions. Why we use coppicing Coppicing is the woodland management technique of repeatedly felling trees at the base or stool , and allowing them to regrow, in order to provide a sustainable supply of timber.
These pruning techniques are simple to master and can make a real difference to your garden. Coppicing is a traditional woodland craft used to produce strong young stems for fencing, fuel or building. Pollarding is similar to coppicing but plants are cut back to a stump, rather than down to the ground.
Pollarding is a pruning technique used for many reasons, including: Preventing trees and shrubs outgrowing their allotted space. Pollarding can reduce the shade cast by a tree. May be necessary on street trees to prevent electric wires and streetlights being obstructed. Pollarding is a method of pruning that keeps trees and shrubs smaller than they would naturally grow.
It is normally started once a tree or shrub reaches a certain height, and annual pollarding will restrict the plant to that height. Done correctly, by professionals, pollarding or coppicing will not kill your tree.
On the other hand, tree topping — a one off lopping off of all growth to a similar height, without regard for the health of the tree — offers no control over the shape of regrowth and usually leaves the tree prone to disease.
A crown lift is the pruning technique of removing lower branches on a mature tree which lifts the canopy or crown of the tree. It brings to mind all the horrors that large corporations have inflicted upon our natural resources and beauty, all in the name of profit. I can only hope that it is not too late for the human species to leave this self destructive path and come back to the light.
Stop eating non human animals, no more 'cattle' or factory farms or killing fields. Plant industrial Hemp where the 'cattle' used to be. Stop destroying forest lands. Selective logging system is a policy in the Philippines. It was pioneered by Forester Martin Reyes. Young trees with a diameter or 40 t0 60 cm are to be spared and protected during logging. These are to be marked so that the loggers would not harm them. I was employed as a tree marker in one summer break when I was in high school.
Some seedlings are to be planted as replacement for each tree cut down. Thanks bulama2. I only wish more of the large companies around here would realize it too! Glad you liked my hub :. Great Hub. Selective logging is definitely the best way for the logging industry to be sustainable. So many trees have been cut down around here in the past twelve months;some have chopped down so many that it looks so bare.
Thank you so very much for this very interesting read. Here's to many more to come. Enjoy your day. Thanks Mommymay! Living in Oregon it breaks my heart seeing how young all of our forests are when I know that we had ancient forests years ago. Our mountains look like patchwork quilts because of all the clear cutting.
I feel real strongly about updating the harvest methods, but unfortunately the logging industry can't see past the quickest route to profit. Thanks for the comment and the support!
Great hub! I am not a vigilant "tree hugger" as my husband sometimes calls me but admit that I was disturbed watching a tv show yesterday after seeing the many trees destroyed for potential gold. I am not against logging either because we need the things provided by wood - and gold for that matter.
Its nice to see that there may be options to save both the forests and industry! Sutherland, L. Dicks, S. Smith eds What Works in Conservation List of journals searched by synopsis. All the journals searched for all synopses.
Close non-essential roads as soon as logging operations are complete. Leave hollow trees in areas of selective logging for sleeping sites. Reduce the size of forestry teams to include employees only not family members. Thank you for considering submitting additional evidence about this intervention. Ideally we would like all submitted evidence to have been published in peer-reviewed literature. However, we do welcome evidence of any nature.
Please be aware that given the volume of work we have we cannot guarantee a response to every submission. This score is based on the direction and size of the effects reported in each study. There is some variation between actions, e. The effectiveness score does not consider the quantity or quality of studies; a single, poorly designed study could generate a high effectiveness score. How certain can we be that the effectiveness score applies to all targets of the intervention e.
This score is based on the number, quality and coverage species, habitats, geographical locations of studies. Actions with high scores are supported by lots of well-designed studies with a broad coverage relative to the scope of the intervention. However, the definition of "lots" and "well-designed" will vary between interventions and synopses depending on the breadth of the subject. The overall effectiveness category is determined using effectiveness, certainty and harms scores generated by a structured assessment process with multiple rounds of anonymous scoring and commenting a modified Delphi method.
In this assessment, independent subject experts listed for each synopsis interpret the summarized evidence using standardised instructions. What Works in Conservation provides expert assessments of the effectiveness of actions, based on summarised evidence, in synopses. Subjects covered so far include amphibians, birds, mammals, forests, peatland and control of freshwater invasive species.
More are in progress. More about What Works in Conservation. An online, free to publish in, open-access journal publishing results from research and projects that test the effectiveness of conservation actions.

With selective cutting , only some of the trees in an area of forest are cut down at any one time. The next time, a different age group or species of tree in the forest is harvested. Similarly, what are the benefits of selective cutting? Some of the advantages of selective cutting are: It supports more varieties of wildlife.
It is more resistant to disease and insect manifestations. It leaves a lighter ecological footprint. It creates a more natural-looking forest stand after harvesting. Similarly, what are the pros and cons of clear cutting and selective cutting when harvesting lumber?
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. Selective logging is often considered a better alternative to clear cutting in which a large area of a forest is cut down, leaving little behind except wood debris and a deforested landscape.
The ecological, social, and economic impacts drive a better understanding of efficient forest management techniques. 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.
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.
