| Abstract | Planning of fuel treatments for ecological or social purposes requires an in-depth understanding of the conditions associated with the occurrence of free-burning fire behavior for a given area of concern. An analysis of the fire environment at Army Garrison Camp Williams in north-central Utah has been completed as a prerequisite for just such an undertaking. Overall the terrain would be generally regarded as mountainous in nature. Topographic information was summarized using a digital elevation model (DEM) that allows for the determination of the land base to be expressed in terms of slope steepness, aspect, and elevation, as well as a visualization map. The majority of the landscape is characterized by slopes less than 40% with slightly more north and east aspects than south and west with elevations largely ranging from 1650 to 1950 m MSL. Fire weather data were compiled from the three nearest remote automatic weather stations (RAWS) within and adjacent to the military installation and summarized according to diurnal and seasonal (from March to October) trends in ambient air temperature, relative humidity, 6.1-m open wind speed, and in terms of 1-, 10-, and 100-h dead fuel moisture timelags. Average temperature maxima (32 °C) and relative humidity minima (12%) usually occurred from 1400 to 1500 hours daily and from July to August seasonally. The predominate vegetation type complex is grass followed by lesser amounts of Gambel oak, sagebrush and some juniper. A fire behavior fuel model map was 1 Coauthors: Martin E.

The semi-arid climate of Army Garrison Camp Williams coupled with its corresponding preponderance of flashy fuel types and sloping terrain constitutes a formidable fire environment. |
