Presentation Transcript

  1. 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

  2. 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

  3. Supplementing Existing BP & FIL Data with Crop BP &FIL for DOI Lands • Methods: Create Fuel Model Map of NB3 Areas • Extract areas classified as NB3 in LANDFIRE FBFM40 fuel model layer

  4. Supplementing Existing BP & FIL Data with Crop BP &FIL for DOI Lands • Methods: Create Fuel Model Map of NB3 Areas • Determine Crop type in areas designated NB3

  5. Supplementing Existing BP & FIL Data with Crop BP &FIL for DOI Lands • Methods: Create Fuel Model Map of NB3 Areas • Assign Fuel Model to Crop Type based on fine fuel loading figures described in CDL research (representative fuel models based on Scott & Burgan FBFM 40 fine fuel loading)

  6. 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

  7. 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

  8. 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.

  9. 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.

  10. 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

  11. 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.

  12. Supplementing Existing BP & FIL Data with Crop BP &FIL for DOI Lands • Methods: Assign representative BP & FIL values to cropland designated NB3 based on existing FBFM BP &FIL values

  13. 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
