This photo-series was designed to present photographs and a detailed inventory of fuels for important stands in the Boreal and Great Lakes - St. Lawrence Forest Regions of Ontario. Over the last 20 years, an experimental burning program conducted by Forestry Canada, Ontario Region has resulted in detailed documentation of fuel loads in selected fuel types. However, very little quantitative data has been gathered on the majority of Ontario's fuel complexes that are found in the Boreal and Great Lakes - St. Lawrence Forest Regions. During the first phase of the study, a database was compiled on natural fuel loads for 300 stands in a variety of fire-dependent ecosystems across northern Ontario. The 75 stands included in this document depict a representative cross-section of fuel types from the 300 stands. All stands were coded according to the Forest Ecosystem Classification (FEC) system of Ontario, in anticipation that this classification system will find increasing application across many forestry disciplines, including fire management. With the move toward computer modeling of remote sensing data in conjunction with analysis tools such as Geographic Information Systems (GIS), fuels data such as that presented here will be useful in calibrating fire behavior and fire growth models. The photo-series and data will help fire managers to interpolate between specific fuel types found in the Canadian Forest Fire Behavior Prediction (FBP) System. The document can also be used as a training tool at the operational fire management level to demonstrate the variability within and between fuel types across the province.
