Aldo Leopold's profound Land Ethic expression culminated in the 1949 classic A Sand County Almanac. The Handbook authors describe their own meaningful experiences living land ethics now in New Mexico. We recognize the contributions of Aldo's early work in the U.S. Forest Service and wife Estella's New Mexico traditions. As the concept of Land Ethic evolution began here, the Handbook guides readers on appreciation opportunities now. Dr. Richard Rubin is steward of the Leopolds' historic Tres Piedras home and scholar of the modern Forest Service conservation mission. Andrew Gulliford is Professor of History at Fort Lewis College and a deeply engaged citizen of the wild. Leeanna Torres is a Nuevomexicana environmental scientist, writer, and daughter immersed in family querencia life. This informative and compelling book will speak to all people living in New Mexico who care about our land. It will enrich visitors' experience exploring New Mexico history, culture, and ethical environmental vigor.
