The "Aldo Leopold Foundation" of Baraboo, Wisconsin, was founded in 1982 by Aldo and Estella Leopold's five children as a 501(c)3 not-for-profit conservation organization whose mission is "to foster the land ethic through the legacy of Aldo Leopold." The Aldo Leopold Foundation owns and manages the original Aldo Leopold Shack and Farm and 300 surrounding acres, in addition to several other parcels. Its headquarters is at the green-built "Leopold Center", where it conducts educational and land stewardship programs. The foundation also acts as the executor of Leopold's literary estate, encourages scholarship on Leopold, and serves as a clearinghouse for information regarding Leopold, his work, and his ideas. It provides interpretive resources and tours for thousands of visitors annually, distributes a curriculum about how to use Leopold's writing and ideas in environmental education, and maintains a robust website and numerous print resources. In 2012, in collaboration with the United States Forest Service, the foundation and the Center for Humans and Nature released the first high-definition, full-length film about Leopold, entitled "Green Fire: Aldo Leopold and a Land Ethic for Our Time." The film aired on public television stations across the nation and won a Midwest regional Emmy award in the documentary category.
