|Assistant Professor Nathan Sayre is a human geographer with interests in the transformation and management of the earth's environment. He studies the management and ecology of rangelands, social theory and the transformations of Western rangelands under the influence of livestock production, urbanization and conservation.
His most recent book, Working Wilderness, is a case study of the Malpai Borderlands Group, a community-based conservation effort led by ranchers in far southeastern Arizona and southwestern New Mexico. His current research focuses on the political ecology of rangelands along the border in northwestern Mexico.
Professor Sayre's teaching interests and philosophy reflect a broad training in the social sciences and more specialized expertise in Western environmental history, range ecology and management, environmental regulation and pastoralism. He also co-teaches a course on Global Warming with Professor John Chiang.
His research interests include ranching and pastoralism, rangeland ecology and management, history of range science, endangered species, scale, the state, Western environmental history, and urbanization/land use change.
