Social • balance between social, economic, and ecological sustainability Ecological Economic Characteristics of Emerging Forest Management Philosophies SFM, ecosystem management, ecological management • systems-based, process oriented • stand and landscape level • current and future needs
Wildfires are a natural component of boreal and subalpine forest ecosystems Ecological benefits • ecosystem health • biodiversity • landscape metrics Socio-economic impacts • life and property • timber supply • water and air quality
It is neither economically possible nor ecologically desirable to eliminate fire from the ecosystem. • Forest management becomes a form of risk • Short-term socioeconomic risks associated with fire • Longer-term ecological risks associated with no-fire • Requires proactive, landscape level, long-term thinking that acknowledges the value of ecosystem processes
Fire-Smart Forest Management: The Concept
Minimize Area Burned Forest Mgt Fire Mgt • site preparation • regeneration • stand tending • harvesting systems and scheduling • block layout and design • road construction • prevention • suppression Fire-Forestry Relationship Under Sustained Yield Maximize Fibre Production
Fire-Smart Sustainable Forest Management Objective: To use forest management activities in a planned and strategic manner to: • reduce the area burned by undesirable wildfires and • reduce the risk associated with the use of prescribed fire Working with nature to determine where and when to put and/or allow fire on the landscape while minimizing short- and long-term risk
Forest Management site preparation, regeneration, stand tending, harvesting systems and scheduling, block layout and design, road construction Behaviour potential Ignition potential Suppression capability Number of escape wildfires Risk associated with prescribed fire Area burned by escape fires Social, economic, and ecological effect of fire Fire-Smart Sustainable Forest Management
Creating and Evaluating Fire-Smart Landscapes: An Exploratory Example
Factors affecting fire behavior Vertical arrangement Moisture content Size and shape Compactness Fuel loading Continuity Chemistry Steepness of slope Position on slope Aspect Elevation Shape of landscape Fuels Topography Weather Wind speed and direction, Relative humidity Precipitation, Temperature, Atmospheric stability
Use forest management to manipulate the forest fuels • Reduce fire intensity and spread potential • Increase suppression effectiveness

Creating a Fire Smart Landscape Understanding Fire and the Fire Environment • Assessment Data • Fire history • Fire weather • Large fire spread patterns • Fire occurrence risk • Fuels and current fire behaviour potential • Topography • Local knowledge of values (forestry, water, infrastructure, critical habitat, etc.)
