The Crevice Cabin Project recommends a strategy to protect human life and create defensible space for a culturally significant resource. The analysis of environmental and economic factors determines an appropriate long-term mechanical fuels treatment strategy in accordance with National Park Service and Yellowstone Park resource programs. The scope of analysis covers a time frame of 150 years, assuming the cabin will remain in active use. It is also assumed that the climate and fire regime will remain relatively the same, and that the 90th and 97th fire indices stay constant. The baseline 400-foot radial treatment zone (The calculated treatment zone uses radiant heat and flame length data, and is based on radiant heat energy requirements of safety zones 1.) mandated by the Yellowstone Hazard Fuels Management Guide is based on average 100-foot flame lengths typical of Yellowstone fuels driven fire behavior at critical indices. (A fire management) challenge is the sporadic and patchy nature of fires where the fire-return interval exceeds 25 years (typical of Yellowstone), particularly in cooler Douglas fir (and lodgepole pine) forests. Prescribed burning is difficult because the "window" for adequate burning (from too moist to too dry) is narrow. 2 Furthermore, current direction from the Yellowstone Center for Resources [YCR] (resource management) indicates that implementation of broadcast burn prescribed fire projects in the wilderness of Yellowstone (even around structures) is restricted in favor of natural fire processes. The proposed strategic solution presented here is driven by this specific management objective (assumed to remain static over the study period), and by the inherent limitations of the Yellowstone fire environment. Finally, the information and treatment strategy derived from this analysis would serve as a project implementation template/guide applicable to other backcountry cabins in Yellowstone. This paper was submitted in partial fulfillment of the requirements for the Technical Fire Management program.
