From the original SCA volunteers at Grand Teton and Olympic National Parks in 1957, through our subsequent alliances with national forests and wildlife refuges, the introduction of urban conservation programs in the 1970s, our landmark Greater Yellowstone Recovery Corps, and the Presidential Citizens Medal presentation to SCA Founder Liz Putnam, SCA has blazed a trail of youth service and stewardship all across America — a movement that today exceeds 130 conservation corps nationwide.
