Aldo Leopold

Also known as: Aldo Leopold

(1887–1948) American forester, ecologist, conservationist, and author whose 1949 essay collection *A Sand County Almanac* is the foundational text of American conservation ethics. Leopold spent the formative years of his career in the U.S. Forest Service in the Southwest, then moved to the University of Wisconsin in 1933 as the country's first professor of game management. From his weekend retreat at the abandoned 'Sand County' farm in central Wisconsin (just east of the Driftless boundary) and from the surrounding Wisconsin landscape, he developed and articulated the *land ethic* — the principle that the human community must enlarge its boundaries 'to include soils, waters, plants, and animals, or collectively: the land.' His 1933 Coon Valley Project — the first large-scale watershed-restoration project in the United States — was conducted in the Driftless coulees and became the template for the federal Soil Conservation Service approach. The intellectual lineage that connects Driftless soil-conservation practice to modern regenerative agriculture runs directly through Leopold.

Aldo Leopold was born in Burlington, Iowa in 1887, trained at the Yale School of Forestry, and spent fifteen years in the U.S. Forest Service in the Southwest — including a long tenure in the Gila National Forest, where his early advocacy resulted in the first formally-designated wilderness area in the American national-forest system (Gila Wilderness, 1924). In 1933 the University of [[viroqua|Wisconsin]] appointed him to a chair in game management — the first such professorship in the United States. He held it until his death in 1948.

The 1933 Coon Valley Project was Leopold’s most consequential field-applied work. Coon Valley, in the [[driftless-area|Driftless]] coulee country of Vernon County, Wisconsin, had been gullied and degraded by half a century of conventional plow-the-slope farming. Leopold helped lead the federal-academic-farmer partnership that pioneered contour strip-cropping, streambank fencing, and integrated farm-watershed planning across the entire valley. The project reversed the worst of the gullying within a decade and became the template for [[soil|the Soil]] Conservation Service approach that the Roosevelt administration deployed nationally. Modern Driftless agriculture — and a substantial portion of modern American soil-conservation practice — descends directly from this work.

His most lasting contribution is the book published the year after his death: [[a-sand-county-almanac|A Sand County Almanac]] (1949). Built around weekend journal entries from the abandoned farm Leopold and his family rehabilitated in central Wisconsin’s Sand Counties (just east of the Driftless boundary), the book articulates the land ethic — the proposition that the human community must enlarge its moral boundaries ‘to include soils, waters, plants, and animals, or collectively: the land.’ The land ethic is the philosophical substrate beneath nearly every subsequent American conservation movement. [[wendell-berry|Wendell Berry]], [[wes-jackson|Wes Jackson]], [[the-land-institute|the Land Institute]], the regenerative-agriculture movement, and the modern public-lands debate all stand on Leopold’s land ethic.
