From forestry to wildlife management
Born in Burlington, Iowa, Leopold graduated from Yale’s forestry school and worked in the US Forest Service in the Southwest. His interests expanded from forest management to wildlife and habitat.
He later taught and researched wildlife management at the University of Wisconsin and helped establish wilderness and wildlife organizations. Land use, animal populations and human responsibilities became connected concerns in his work.

Research, restoration and observation
Leopold was the University of Wisconsin Arboretum’s first research director and participated in its design. He spoke at its dedication on 17 June 1934, leaving an account of its early purpose.
The Arboretum linked observation and ecological research with the restoration of land. Leopold’s writing likewise attended to seasonal changes, animal activity, vegetation and work on the land rather than conservation in the abstract alone.

A Sand County Almanac
A Sand County Almanac was first published in 1949. Drawing on observations in Wisconsin and elsewhere, its calendar essays organize natural events through the months of the year.
Leopold dated the foreword in March 1948 and died shortly afterwards. The book connected natural-history observation with reflection on land management and became an important vehicle for his conservation ideas.
Membership in a land community
The land ethic extends ethical concern to soils, waters, plants and animals. In this account, people are members of a land community, responsible for considering effects on other members and on the community as a whole.
It is an ethical proposal about how people ought to treat land. Drawing on ecological interdependence, it questions evaluating land solely by its immediate economic uses.
