What I am advocating is that it is important to evolve with the changing world and technologies. Clear cutting is not necessary, nor is it practical. Logging should instead be done using methods that create sustainable yield, which ensures that no more is harvested than can be naturally replenished Dadd.
Rather than removing dozens of acres of healthy, bio-diverse forests, we should instead be using the sustainable yield method of selective cutting.
Selective cutting, also called selective thinning, involves carefully choosing which trees to log while leaving the rest of the forest intact. This process allows for better yield and productivity over several decades. Each year provides trees for harvest, rather than having to wait a minimum of sixty years after a clear cut. According to Merve Wilkinson, a Canadian land owner and esteemed author on alternative forestry, over a year period he has been able to harvest over 1,, board feet of timber from his property using the selective cutting method.
Today, he still has nearly as much timber left as when he bought his property, which was estimated at 1,, board feet in Clark. It is discussed in an article written by Earl Clark that Wilkinson has been able to achieve a ten percent growth rate annually because of his selective cutting. His land is continually making him money; there is no loss in profit because he does not have to wait several decades for another harvest.
There is no resource that does so much for man as the forest and yet we give it so little consideration. Forests are there for our use, not for us to abuse, for the forest governs our water and air, helps control weather, and moderates heat and cold qtd.
These words spoken by Wilkinson show the wisdom of his years. We cannot simply continue as we have for the last one hundred years simply because it yields the fastest profit.
In actuality, continually thinning and managing our forests in a sustainable manner will not only ensure that future generations may witness the awe inspiring beauty of an old-growth forest, but it also ensures steady jobs for those thousands of Americans who rely on the timber industry to survive for many more decades to come. It is time we take responsibility for our environment and our economy and learn how to value our resources for something beyond their monetary potential.

Cleat cut logging is still prevalent in Washington State north of Grays Harbor. I am on a three month work assignment in Ocean Shores and drive to Aberdeen weekly for shopping.
Driving through those areas that are clear cut is so depressing. The scrap wood is piled up in big stacks and the mountainside looks like a combat zone.
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. Wilson H. Read more. Read less. One site comparison in Sierra Leone found that primate densities were higher in forest that had been logged at low intensity than in a forest logged at high intensity.
One before-and-after study in Madagascar found that the number of lemurs increased following selective logging. One site comparison study in Uganda found that primate densities were similar in forest that had been logged at low intensity and forest logged at high intensity. Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.
A site comparison in in rainforest in Gola Forest Reserves, Sierra Leone found that group densities of three out of six primate species were lower in selectively logged than in unlogged forests.
Diana monkeys Cercopithecus diana , spot-nosed monkeys Cercopithecus petaurista , and Campbell's monkeys Cercopithecus campbelli had similar group densities in low-intensity selectively logged and unlogged forest patches. In contrast, group densities of red colobus Procolobus badius , black-and-white colobus Colobus polykomos , and olive colobus Procolobus verus appeared lower in selectively logged than in unlogged forests. Group densities of all species were lower in heavily selectively logged forest than in unlogged or low-intensity selectively logged forests.
Group densities for Campbell's monkeys were similar in unlogged and logged forests. Hunting rate was highest in high-intensity selectively logged forests, moderate in selectively logged forests and low in unlogged forests. However, no statistical tests were carried out to determine whether this difference was significant. Sample sizes were small and ranged from one to seven groups. Selective logging involved the cutting of commercial tree species with a girth larger than Encounter rates did not change for the brown lemur Eulemur fulvus , Verreaux's sifaka Propithecus verreauxi , Lepilelur mustelinus , and Coquerel's giant mouse lemur Mirza coquereli.
Encounter rates increased from 0 to 2. However, the authors speculated that the increase was a consequence of a shift in home ranges between surveys, rather than population growth, as most of the species reproduce too slowly to cause a noticeable effect within two years.
The same site was surveyed during the day and at night repeatedly and along the same trails in before logging and in after low-intensity selective logging. Authors also surveyed two additional sites, one logged in and one unlogged area to control for potential year-to-year population variation. A site comparison in in three evergreen forests in Uganda found that light selective logging 5.
However, group density of eastern black-and-white colobus BWC Colobus guereza was lower in the light selective logging area in 3. Heavy selective logging resulted in lower group densities compared to unlogged and light selective logging for red colobus 3. BWC relative abundance decreased in unlogged areas from 0. Surveys used line transect methods to assess primate densities across three forestry compartments with heavy-, light- and no selective logging in the late s.
The unlogged area was surveyed in Survey effort and data collection methods were comparable. Junker, J. Pages in: W. Sutherland, L. Dicks, S.

Thank you for considering submitting additional evidence about this intervention. A few weeks go by and you decide to tap the bucket for some change again.
This time you reach in and grab all of the dimes and most of the nickels. What are you left with now? The bucket still looks full but there is not much of value left in it. On the first cut all of the large diameter, clean, straight, valuable specie trees get cut along with a few of the medium diameter trees as well the quarters and a handful of dimes. This type of harvest is very common.
Its often used as a sales pitch by people looking to buy standing timber from landowners. In a forest canopy you have three main categories into which each tree fits. Dominant, Co-dominant and Suppressed. The key to good forest management is to identify, prior to harvest what trees are Dominant and focus on leaving these trees to grow longer.
Under good forest management, the focus on the first harvest would be to remove a large percentage of trees that are suppressed, exhibiting poor form and of low value. Included would be removal of a number of the co — dominant stems that are competing for sun and space with the most valuable dominant stems. Practiced consistently over time it will exponentially increase the value of the trees present on a woodlot. As an illustration lets picture an even aged hardwood forest found here in Vermont.
Under good forest management a harvest conducted in a stand like this would involve removal of most of the Beech outside of a few wildlife trees , all of the White Birch and Aspen and suppressed Yellow Birch and Maple. The only large diameter high value Maple , Yellow Birch and Cherry that would get cut on this first harvest would be those trees that have less than perfect form some crookedness to them and are competing with the crowns of the most perfect trees of the same species.
This last winter Stillwater Forestry had the pleasure of conducting a timber sale on woodlot, here in Vermont, that we had worked on in
