Richard Teague is Associate Resident Director and Professor of Sustainable Rangeland Management at Texas A&M AgriLife Research and Extension Center. His philosophy is that research and service must provide the linkage that enables managers to base decisions for sustainable land use on the principles of ecosystem function. He uses four key elements to enhance this linkage: a systems research program, resource accounting, long-term assessment and partnering with rancher clientele. His goal is to use a systems approach in developing land and livestock management practices that sustain natural rangeland resources and the people depending on the land. His work includes studies of holistic management practices published in professional journals.
