A period of landmark federal conservation legislation begins with passage of the Wilderness Act. The following year, Congress enacts the Land and Water Conservation Fund Act, and in 1968 the National Wild and Scenic Rivers Act and the National Trails Act are approved. 'Our conservation must be not just the classic conservation of protection and development, but a creative conservation of restoration and innovation. Its concern is not with nature alone, but with the total relation between man and the world around him. Its object is not just man's welfare but the dignity of man's spirit.' President Lyndon B. Johnson, Message on Natural Beauty.
