Yet in this particular part of California, wildfire was an important ecological factor that on occasion would normally burn at least some of the forest stands.
One of the noticeable things about the managed forest we visited was the absence of big woody debris logs on the forest floor compared to the nearby wild forest. However, since the logging is done over a period of years—not all trees are removed at the same time as in a clearcut.
For instance, the company forest management plans call for the eventual cutting of all trees on any particular area. But it is these rarer genes that may sustain the forest in times of adversary—sustained drought, new insect attacks or whatever.
Weeds were far less of a problem as a consequence. It has been my experience, if someone is exploiting natural landscapes in a manner that is commercially viable; the activity is typically not ecologically sustainable.
Again because there was still some salmon spawning in the waterway, the company used that to prove its practices were benign. In addition to these physical differences, there were other potentially important losses. They remain longer on the ground, in streams, and provide structural diversity to the forest floor and stream channels.
After the tour, I visited a nearby state park that had wild unmanaged forests. The forestry procedures I saw on the tour were a vast improvement over the cut and run practices of the past. Disease and insect outbreaks are also equally unwelcome, though these are important ecological processes in most forest ecosystems.
But is it not providing a sustainable ecosystem. However, whether they are truly ecologically sustainable as is often implied is questionable. They typically did not cut existing old growth trees. These logs help to create fish habitat, and armor the banks against erosion.
Typically such fires would create a mosaic of burned and unburned forests, release nutrients, and clean the forest. After all on most forest lands we have only gone through rotations cuttings and like a corn field, we can get a few harvests from the land before the soil productivity is depleted.
And though the company foresters had a prescription that left a few snags per acre, the number of large snags was considerably less than what I observed in the wild forest. The company owners and foresters who led the tour were definitely proud of their efforts.
Thus the site does provide a sustainable supply of fodder for the mill. George Wuerthner There has been a lot of positive talk about sustainable forestry by the timber industry, politicians, and even among many environmental groups. Unfortunately you cannot be removing a significant amount of biomass from a forest and be saving the parts—the logs removed are the cogs and wheels needed for a functioning ecosystem.
Soil erosion, particularly that from logging roads, was also an issue and one that never disappeared because once they constructed their main roads for timber management access, they did not remove them. So sustainable grazing is about avoiding overgrazing. Though the differences might not be apparent to the causal visitor, I saw substantial physical differences between the managed company lands and the wild forest.
While on the wild forest, the percentage of old growth will vary over time depending on things like wildfire or insect attacks, but no matter what disturbs the forest—over time the wild forest will again have significant amounts of old growth.
For instance the company lands I visited had been selectively logged at least three times in the past years and it still had trees on it. Because of the competition with other trees, the rings were close and tight. As Aldo Leopold admonished years ago the first precaution of intelligent tinkering is to keep every cog and wheel.
Thus they remained as a long term source of sedimentation. Everyone is looking for a way to exploit the Earth and pretend they are not impacting anything.Aug 22, · According to the dictionary, “literally” now also means “figuratively” Thanks in part to the overuse of “literally,” Merriam-Webster says the word can now mean its exact opposite.
Huh? May 04, · By sustainable, timber companies and their supporters in the “sustainable forestry” movement are engaged in practices that ensures a continual long-term timber supply.
For instance the company lands I visited had been selectively logged at least three times in. The way of the forest sector towards sustainable development is explored by analysing the following sustainability criteria: economics of forest use; forests' contribution to soil protection and carbon sequestration; the institutional framework in forestry and the necessity of its transformation in line with the requirements of the transition economy.
Sustainability and Sustainable Development DEFINING A NEW PARADIGM In the World Commission on Environment and Development sought to address the problem of conflicts between environment and development goals A formal economic analysis then raises the question of whether.
