The Canadian Forest Fire Behaviour System is a systematic method for assessing wild land fore behaviour potential. The guide provides a simplified version of the system, presented in tabular format. It was prepared to assist staff in making first approximations of FBP system outputs when computer-based applications are not available. Quantitative estimates of head fire spread rate, fire intensity, type of fire, and elliptical fire area, perimeter, and perimeter growth rate are provided for sixteen discrete fuel types within five broad groupings (coniferous, deciduous, and mixed wood forests, logging slash, and hrass), covering most of the major forest fuel types found in Canada. The FBP system is intended to supplement the experience and judgment of fire managers.
