(d) Why should selective cutting be implemented? The Amazonian forest contains 20 to 60 trees in acre, but only one or two can be used for industrial purposes. Only these trees can be felled economically because exploration requires heavy, expensive, high-oil consumption equipment. This machinery can be amortized only by cutting large, high- yield trees. The main advantage of selective cutting is that the younger trees get more access to light and water, accelerating the natural growth cycle of the forest.
