Primary responsibilities are to develop the understanding necessary to guide the stewardship of fire as a natural process in wilderness. This includes: 1) studying natural fire regimes and how they have been altered by management, 2) evaluating options for the stewardship of fire as a natural process and the consequences of these management alternatives, and 3) seeking to understand the social and institutional factors that influence the evaluation of tradeoffs by fire managers and members of the public.

importance of research
Managers of protected areas, such as wilderness, have the challenge of restoring or maintaining the disturbance process of fire while considering a suite of other social and ecological values inside and outside the boundaries of these areas. Their decisions can have long lasting consequences that are difficult to predict. Fire suppression is the dominant fire management strategy across all land designations, and in many areas, suppression has contributed to increasing hazardous fuel accumulations, increasing probability of extreme fire behavior and effects, and altered ecosystem structure and function. These results run counter to protected area management goals, and continue to increase the vulnerability of nearby human communities to wildland fire. Fire suppression also has helped to distort human perceptions of natural systems. The orientations toward fire management held by the public and government agencies need to shift away from suppression as the dominant strategy and toward a stewardship of the process of fire that includes natural and prescribed fire.
