The FFI ecological monitoring utilities are an integration of FEAT and FIREMON, two respected, science-based programs used for fire effects monitoring on public lands. Funded by the Interagency Fuels Management Committee and developed jointly by the National Park Service and Forest Service, FFI is designed as a comprehensive, database-driven framework that organizes sampling protocols, stores field data, and provides analysis tools for vegetation sampling and monitoring programs. FFI is designed for people with vegetation sampling experience who need a way to organize their sampling data so that it can be readily accessed. This user guide has been updated for FFI v1.05.00 and FFI-Lite v1.05.00.
