Aldo Leopold An index to his ideas about biology & biogeography on this site.line

Aldo Leopold's "shack" in Baraboo, Wisconsin.


A Taste for Country, is an essay about property disposal, symbiosis and the extension of ethics to the varied and -- often uneconomical -- productive sources of biological wealth.

Leopold explores the importance of the biological food chain and the cycle of life in Thinking Like a Mountain.
