This comprehensive guide provides essential lessons for using FOFEM 5, a tool designed for predicting fire effects in forest management. It includes background information, discussions on FOFEM modules, detailed step-by-step exercises, and methods for saving projects and outputs. Topics covered range from first-order fire effects to advanced modules like soil heating and smoke emissions. Users will learn how to input data effectively, interpret outputs, and use FOFEM in conjunction with GIS for better fire management decisions.

Learning to Use FOFEM 5Volume I: Basic Lesson Missoula Fire Sciences Laboratory Systems for Environmental Management Learning to Use FOFEM 5: Basic Lesson
In the Basic Lesson… • Background information • Discussion of FOFEM modules, inputs and outputs • Step-by-step exercises • Saving a FOFEM project and FOFEM outputs Learning to Use FOFEM 5: Basic Lesson
In the Advanced Lesson… • Advanced use of soil heating and Burnup modules • Batch mode: making many runs at once • Linking FOFEM to GIS Learning to Use FOFEM 5: Basic Lesson
What is a “first-order” effect? • “First-order fire effects” are the immediate consequences of a fire, whether direct or indirect. • FOFEM 5 predicts: • Fuel consumption • Smoke production • Tree mortality • Soil heating • Second-order effects? • Longer term effects and effects involving interaction with other agents, like erosion, vegetation dynamics, insect-caused mortality, and climate change. • Modeled with VDDT, LANDSUM, SIMPPLE, TELSA, FFE-FVS and other models Learning to Use FOFEM 5: Basic Lesson
How FOFEM works • FOFEM 5 is a compendium of models for predicting fire effects • FOFEM 5 helps the user generate inputs for those models from • Detailed fuel and stand inventory data • General forest type information • A combination of these two sources • FOFEM 5 automatically uses the best available equation or model Learning to Use FOFEM 5: Basic Lesson
These modules have similar inputs FOFEM 5 modules • Mortality • Fuel consumption • Smoke • Soil heating Learning to Use FOFEM 5: Basic Lesson
Choose region Set fire severity Select “mortality” Define tree list Set fire intensity Tree mortality: inputs Learning to Use FOFEM 5: Basic Lesson
