Key Concepts

  • Fire intensity – energy release, links to wildfires
  • Burn severity – impacts on ecology/ecosystem services
  • The types of fire behaviour that represent intense and/or severe fires
  • The main factors that affect fire behaviour: wind, slope, aspect, fuels (especially fuel moisture)
  • Three main reasons why wildfires occur:
    • Fire behaviour exceeds expectations.
    • Control resources are inadequate for the expected fire behaviour.
    • Control lines (firebreaks) are inadequate for the expected fire behaviour.
  • Threshold of control for main suppression methods
  • Fire return interval / rotation length
