The School of Natural Resources and the Environment is concerned with the management and conservation of natural ecosystems with emphasis on the desert, rangeland, and forest ecosystems of arid and semi-arid environments. Graduate programs leading to the degrees of Master of Science and Doctor of Philosophy prepare students for (1) research and teaching in the areas of natural resource science, conservation, management, and planning, and (2) positions in natural resource management agencies and organizations. All students are urged to gain a broad understanding of social and political institutions as they affect fundamental relations of humans and their environment, particularly those involving plants, animals, soil and water resources, and climate. Students pursuing the M.S. or Ph.D. degree may elect one of four disciplinary emphasis areas: Ecology, Management, and Restortation of Rangelands, Natural Resources Studies, Watershed Management and Ecohydrology, and Wildlife and Fisheries Conservation and Management. Students also may choose from a wide variety of minor subjects, including soil science, watershed management, animal science, wildlife ecology, plant science, ecology, anthropology, public administration, and global change.
