Commercial Logging in the Rainforests


Commercial Logging is become a big problem in the rainforests. Companies cut down mature trees that have been in the forest for hundreds of years. The timber trade defends itself my saying “selective” logging ensures that the forest will re grow over time. But, in most cases this is not true due too the nature of rainforests and logging practices. The heavy machinery used to penetrate the forest and build roads causes extensive damage. The heavy machinery also compacts the soil, decreasing the forests chance of regeneration. Once trees are cut down, they must get them out of the forest. This is often done carelessly, and causes destruction to the rest of the forest. It is believed that in many South East Asian countries between 45-74% of trees remaining after logging have been badly damaged or destroyed.

Commercial Logging & Wild Fires

You would think commercial logging and taking trees out of the forest would decrease the possibility of forest fires, right? Well, when commercial loggers take trees out of the forest, they actually take the least flammable portion of the tree, the trunk. They leave behind tree limbs, leaves and needles, which are the most flammable part of the tree. Commercial logging reduces the the size of the tree canopy, which will change the climate in the forest. Without a tree canopy, the forest floor is exposed to more sunlight and wind, which causes the surface temperature to rise and the air to become dryer. This causes the natural surface fuels to be hotter and dryer, resulting in a bigger, hotter forest fire.
