In his years of government service and private work, Leopold was active in game management and wildlife preservation. His Sand County Almanac was influential with succeeding generations of conservationists.

Biographical Background

Aldo Leopold, born in Burlington, Iowa, graduated from the Yale Forest School (now the Yale School of Forestry and Environmental Studies) in 1906. In 1909, after completing his master’s degree, he joined the U.S. Forest Service and fostered the ecological policies of Gifford Pinchot and Theodore Roosevelt. Stationed in the southwestern United States, he advocated game conservation to avoid the erosion of sport hunting. He also helped establish a 200,000-hectare roadless wilderness in the Gila National Forest. While pursuing wolf eradication to ensure deer viability, he realized the importance of ecological interactions.

Impact on Resource Use

Leopold moved to Wisconsin in 1924, joined the U.S. Forest Products Laboratory, and developed the policy of wildlife management. He published Game Management, subsequently retitled Wildlife Management, in 1933. In the same year, he joined the University of Wisconsin at Madison Department of Agricultural Economics. He assisted Robert Marshall in creating the Wilderness Society in 1935, and he established a one-man Department of Wildlife Management in 1939.

Leopold advocated integration of local concerns with universities, government agencies, and the private sector to balance farming, forestry, wildlife, and recreation. He escaped on the weekends to his sand farm in Wisconsin, where he wrote prolifically. His Sand County Almanac, published posthumously in 1949, represents a lifetime of observations concerning ecology, ethics, and aesthetics and concludes that a policy is right when it tends to preserve the integrity, stability, and beauty of the biotic community; any other policy, according to Leopold, is wrong.
