FFI Sampling Protocols

• Composite Burn Index (FEAT / FIREMON)
• Estimate burn severity rating (0none to 3high)
  for ecological components in several strata
• Strata Scores
• Understory CBI
• Substrates
• Herbs / Low Shrubs
• Tall Shrubs
• Overstory CBI
• Intermediate Trees
• Big Trees
• Total Plot CBI

12
FFI Sampling Protocols

• Normalized Burn Ratio
• Landsat TM/ETM based assessment of fire
  severity.
• NBR (R4-R7) / (R4R7)
• dNBR temporally differenced
• pre- and post-fire data sets
• CBI used to calibrate/validate
• remote sensing results, relate
• radiometric change to actual
• fire effects on the ground
