My research interest is in increasing understanding of rangeland systems and identification of practical, economically advantageous and environmentally responsive management practices. It focuses on human management skill and "soft technology" such as understanding and manipulating plant and herbivore interaction to accomplish resource management objectives. My extension emphasis is centered on management: rangeland resource management, riparian area management, application of ecological principles in management, natural resources conflict management and total ranch management education. I emphasize the human dimension in sustainable resource management.
