Supplementing Existing BP & FIL Data with Crop BP &FIL
• Background– Current BP & FIL grids not showing BP & FIL values
in areas designated NB3 by LANDFIRE– National Agricultural Statistics Service (NASS)
produces cropland data layer (CDL) for all CONUS http://nassgeodata.gmu.edu/CropScape
– Michigan Tech Research institute developed fuel loading by crop type as an input to their studies on wildfire emissions http://wfeis.mtri.org
Supplementing Existing BP & FIL Data with Crop BP &FIL for DOI Lands
• Methods: Create Fuel Model Map of NB3 Areas– Fuel Models applied to NB3 Areas based on fine fuel loading and
substituted in for NB3 pixels
Supplementing Existing BP & FIL Data with Crop BP &FIL for DOI Lands
• Methods: Remove NB3 Areas From Burn Probability (BP) and Fire Intensity Level (FIL) Grids
Supplementing Existing BP & FIL Data with Crop BP &FIL for DOI Lands
• Methods: Extrapolate Burn Probability and Fire Intensity values based on smallest geographically significant area– Agriculture occurs in areas where the fuel model
classification is not geographically similar in non-agricultural areas• Example: GR7 Fuel model assigned to Wheat Crop Type which has
wide distribution across the US.

Example: GR7 Fuel model assigned to Wheat Crop Type which has wide geographic distribution across the US.
Supplementing Existing BP & FIL Data with Crop BP &FIL for DOI Lands
Example: GR7 Fuel model distribution in LANDFIRE FBFM40 layer. The distribution is limited to NE MT, ND, SD, NE, MN
Supplementing Existing BP & FIL Data with Crop BP &FIL for DOI Lands
• Methods: Extrapolate Burn Probability and Fire Intensity values based on smallest geographically significant area– In GR2 & GR3 fuel model datasets the geographic
distribution of the fuel model pixels was wide enough to use matching or geographically similar Fire Planning Units (FPU) as a geographic unit to summarize mean BP & FIL values
– In GR4, GR5, GR7 fuel model datasets the geographic distribution of the fuel model pixels was not wide enough to use FPU as a summary unit, so the mean national BP&FIL values for each fuel model was used.

• Methods: Assign representative BP & FIL values to cropland designated NB3 based on existing FBFM BP &FIL values
Supplementing Existing BP & FIL Data with Crop BP &FIL for DOI Lands
• Methods: Add BP& FIL created for Agricultural areas to existing BP & FIL grids to create final product
