Forestry Systems And Multiple-Use Forestry Forestry Systems and Multiple-Use Forestry In the beginning there were forests stretching as far as the horizon- deep, dark forests were no man had ever set foot. Silence reigned over the treetops; there were no growling bulldozers, caterpillars or trucks spewing black smoke into the air, no saws and chippers chewing through the trees- but times have changed and as the world population explodes and the demand for wood products increases, new ways of managing our forests must be put into practice. The forests of the United States originally compromised about 822 million acres. Now this figure has shrunk to less than half its initial amount (Robinson 12). The key to saving our forests, here in the U.S. as well as internationally, lies in the practice of multiple-use forestry, a technique that was developed by the Forest Service many years ago but which is still unpopular with the lumber industry- mostly because of misconceptions regarding its profitability (www.fs.fed.us/). In this paper I will touch on concepts surrounding multiple-use forestry, namely: its history; an analysis of the process by which it is employed, its relationship with the notion of sustained-yield practices; and its effects on the industry and the environment.
