Description: Fuel model groups describe the fire-carrying fuel type of the surface fuels. The groups are broad categories of burnable fuels based on descriptions of live and dead vegetation that represent distinct fuel types, size classes, and load distributions (amounts) [Landfire 2016]. Standard fuel model groups are grass, shrub, timber, timber litter, timber understory, and slash/blowdown. Fuels and other elements of the fuelscape in the PNW Quantitative Wildfire Risk Assessment were extensively reviewed and refined by local expert consultation. Additionally, the fuelscape was updated to account for wildfire disturbances that occurred through 2017.</br></br><b>Grass:</b> Fuel Models 101-104, (GR1; GR2; GR3; GR4)</br></br><b><Grass/Shrub:</b> Fuel Models 121-123, (GS1; GS2; GS3)</br></br><b>Non-burnable-Other:</b> Fuel Models 91-93,99, (NB1; NB2; NB3; NB9)</br></br><b>Non-burnable-Water:</b> Fuel Models 98, (NB8)</br></br><b>Slash-blowdown:</b> Fuel Models 202, (SB2) </br></br><b>Shrub:</b> Fuel Models 141-147, (SH1; SH2; SH3; SH4; SH5; SH6; SH7)</br></br><b>Timber Litter:</b> Fuel Models 181-189, (TL1; TL2; TL3; TL4; TL5; TL6; TL7; TL8; TL9)</br></br><b>Timber-Understory:</b> Fuel Models 161-163, 165, (TU1; TU2; TU3; TU5)</br></br>(Pacific Northwest Quantitative Wildfire Risk Assessment, USFS, 2018.
