There is relatively little scientific understanding of mixed severity fire regimes, compared to low severity fire regimes. However, mixed severity regimes widespread in the United States, and ecology and fuel treatments must be considered in the current manadate to accelerate fuel treatments must be considered in the current mandate to Ecology and Management has been planned by the Association of Fire Ecology to summarize current knowledge on mixed severity systems and communicate that knowledge to the scientific and management communities. Planning is well underway for this symposium, scheduled for 17-19 November 2004, in Spokane, Washington. By including leaders in the scientific and management communities, the symposium will be able to address science and management needs relative to ecological knowledge, relevant scientific tools, and fuel treatment options. A proceedings will be published to document the outcome of the symposium.
