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 – Michigan Tech Research institute developed fuel loading by crop type as an input to their studies on wildfire emissions

Supplementing Existing BP & FIL Data with Crop BP &FIL Background – We can use these crop fuel loading estimates to estimate a fuel model for each crop type based on fine fuel loading estimate – The resulting fuel model can then be used to estimate BP and FIL – Final result is updated BP/FIL grids that incorporate agricultural lands that have been incorrectly classified NB3 by LANDFIRE

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.

Supplementing Existing BP & FIL Data with Crop BP &FIL for DOI Lands 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.
