Commercial logging destroyed 45 percent of old-growth forests.
Logging, or commercial logging, involves cutting trees for sale as timber or pulp. The timber is used to build homes, furniture, etc. and the pulp is used to make paper and paper products. Logging is generally categorized into three categories: selective, clear-cutting and strip logging.
- Selective logging is selective because loggers choose only wood that is highly valued, such as mahogany.
- Clear-cutting is not selective. Loggers are interested in all types of wood and therefore cut all of the trees down, thus clearing the forest, hence the name- clear-cutting.
- Strip logging involves the clear-cutting of a relatively thin strip of forest that parallels a river (goes along the river) along a slope. A gallery forest (bordering the river) is left intact, but a strip is cut immediately upslope and the desirable timber is removed by a road that is also designed to parallel the river. Following this, another strip is cut several years later immediately upslope to the first strip and the road.
