It is committed to manage, protect, and improve these lands in a manner to serve the needs of the American people for all times. Management is based on the principles ofmultiple use and sustained yield of our nation's resources within a framework of environmental responsibility and scientific technology. These resources include recreation; rangelands; timber; minerals; watershed; fish and wildlife; wilderness; air; and scenic, scientific, and cultural values.
