From the text...'On July 1, 1992, the U.S. Fish and Wildlife Service and the U.S. Forest Service, Intermountain Research Station entered into a cooperative agreement (FWS Ref. No. 14-48-0009-92-962 DCN: 98210-2-3927) to conduct a study on 'Heat Transfer into the Duff and Organic Soil.' The contract called for the Intermountain Research Station's Intermountain Fire Sciences Laboratory to conduct research into the ignition and consumption processes in duff and organic soils, the physical processes of heat transfer in duff and organic soils, and the abiotic and biotic effects of heat on soils. The specific objectives of the project were: 1) Modify and test a preliminary model to predict limits for ignition in duff and organic soil. 2) Describe the depth of organic soil consumption in terms of the physical properties of the organic soils. 3) Develop and test a model to predict heat flux into the unburned organic soil or soil at the burn boundary. 4) Complete development and testing of a preliminary physically-based soil heat and vapor transport model to predict temperature profiles in soils below the burn boundary. 5) Develop models to link post-fire visual fire severity assessments to soils heating models to predict probable fire effects on soils and biological components. 6) Determine the response of select plant response structures to heating at different phenological stages and at different soil conditions. 7) Use ignition, consumption, soil heating, and effects models developed in objectives 1 through 6 to develop a preliminary fire effects assessment system. ...During this project we have discussed prescribed burning with many managers and have had the opportunity to view wildfires and conduct studies on prescribed burns in Alaska and North Carolina. We found a lot of interest in the project wherever we went. Managers were particularly supportive in Alaska and the Southeast. In cooperation with the Croatan NF, The Nature Conservancy, and the State of North Carolina Division of Forestry, prescribed burning plans have been developed for experimental burns that will address some questions and concerns. One prescribed burn has been completed and the data are being analyzed. Others will be completed when the weather cooperates. Support for this project by DOI and the resulting project work has generated support for continuing research. The Missoula Fire Lab and cooperators have been funded by Seymour Johnson Air Force Base to research issues about fuel, flammability, hydrology, and soil conditions that will help them to develop a prescribed burning program at the Dare County Air Force Bomb Range. During the course of this project we hope to conduct several experimental burns to test our ideas and use as demonstrations.'
