This paper outlines the subject matter of research on the physics and phenomenology of' wildland fire, focusing on topics that bear upon issues of fire control and fire safety. Motivations for research on fire phenomenology are identified as arising from the activities necessary to achieve fire-related objectives, including acceptable levels of fire safety. Differences in the activities, techniques, and tactical objectives for control and prevention of' fires in natural fires and in manmade structures are noted. Sources of wildland fire research information and operational planning aids are identified, and some cautions are ventured concerning their use by nonspecialists
