FOFEM (a First Order Fire Effects Model) is a computer program for predicting tree mortality, fuel consumption, smoke production, and soil heating caused by prescribed fire or wildfire.
First order fire effects are those that concern the direct or indirect or immediate consequences of fire. First order fire effects form an important basis for prediction secondary effects such as tree regeneration plant succession, and changes in site productivity, but these long-term effects generally involve interaction with many variables (for example, weather, animal use, insects, and disease) and are not predicted by this program. FOFEM is used by resource managers and planners to provide quantitative fire effects information for tree mortality, fuel consumption mineral soil exposure, smoke and soil heating. FOFEM input files can be created in the FFI ecological monitoring software (www.frames.gov/ffi) or by manually creating an input file in FOFEM’s standard format.
