In 1995, the Canadian Forest Service published two wall posters related to the Canadian Forest Fire Behavior Prediction (FBP) System, both of which will be displayed during this poster paper presentation. One, jointly produced with the Alaska Division of Forestry entitled 'Head Fire Intensity Class Graph for FBP System Fuel Type C-2 (Boreal Spruce),' presents a practical approach for determining one of five possible head fire intensity classes, each illustrated with a representative color photograph, as well as the general type of fire (for instance, surface fire, intermittent crown fire, and continuous fire) and degree of crown fuel involvement. A table accompanying the graph offers additional information on fire potential and management implications. The other, entitled 'Fire Behavior in Three Jack Pine Fuel Complexes,' highlights some of the progress in experimental burning undertaken in Ontario that contributed to the development of the C-3 (Mature Jack or Lodgepole Pine), C-4 (Immature Jack or Lodgepole Pine), and S-1 (Jack or Lodgepole Pine Logging Slash) fuel types found in the FBP System. Four experimental fires were selected to illustrate the potential range in fire intensity within the fuel complex or type, and in each case two representative color photographs are presented along with the attendant burning conditions and ensuing fire behavior characteristics.
