The main objectives of NFMA are to require the U.S. Forest Service to develop plans for national forests, set standards for timber sales, and create policies to regulate timber harvesting. The purpose of these objectives is to protect national forests from permanent damages from excessive logging and clear cutting. Congress requires the Forest Service, in conjunction with other applicable agencies, to thoroughly assess, research, and plan for the nation's renewable resource use, the current demand, anticipated demands, and environmental and economic impacts.
