FUELSGeodataset Name: FUEL or XXXFUEL where XXX is a three letter abbreviation for district Geodataset Type: GRID Geodataset Feature: Surface Integer DESCRIPTION: Fuel map of the state of Florida based on the Anderson classification scheme (Anerson, Hal E. 1982. Aids to determining fuel models for estimating fire behavior. USDA For. Serv. Gen. Tech. Rep. INT-122, 22p. Intermt. For. And Range Exp. Stn., Ogden, Utah 84401).

Fire spreads in annual grasses or periphyton moss (south Florida only) and the fuel bed is < or = 1 foot tall. 2 FM2 GRASS Fire spreads in perennial grassy fuels (1 foot or less) where live fue3l is a part of the system. The density of the overstory or canopy may contribute to a reduced rate of spread and reduce the intensity. 3 FM3 GRASS Fire spreads in grassy fuels without canopy or where a limited canopy has little effect on the rate or intensity, the fuel bed is > 1 foot tall or is cogongrass. 4 FM4 SHRUB Fire spreads in shrubs > 4 feet in height and or melaleuca or cogongrass is present and are likely to contribute to the overall intensity of the shrub ignition, which may and often does lead to canopy involvement. (Scrubby flatwoods, Pine Flatwoods, coastal palmetto, and tall palmetto, Ti Ti, Pine Plantations and Oak scrub). 5 FM5 SHRUB Fire spreads in light, green shrubby herbaceous vegetation often with substantial overstory. However, shrubby flame length rarely lead to or contribute to the ignition of the overstory; wild grape, kudzu, or other vines may be present, but do not provide sufficient age and biomass to contribute as ladder fuels which would lead to canopy involvement. (Young scrub, 1-2 year old plantations, scrubby flatwoods). 6 FM6 SHRUB Live fuels are not present. Fire spreads through patchy shrubs (3-6 feet in height) with little or no logging slash and where canopy closure has little or no effect on the rate of spread, but may require sustained moderate winds to support the rate of spread; an example would be areas dominated by Rosemary Scrub. 7 FM7 SHRUB Live fuels present. Fires spread in shrubs < or = 4 feet in height. Palmetto / gallberry association with pine canopy. Managed pine flatwoods may be represented. 8 FM8 TIMBER LITTER Dead foliage is tightly compacted, short needle (2 inches or less) conifer litter or hardwood litter (Include aged stands of Brazilian Pepper and Australian Pine). 9 FM9 TIMBER LITTER Fire spreads in the surface litter of leafy or fine, blowy fuels. A canopy of long needle pine or deciduous hardwoods contribute to the seasonal accumulation of litter without logging slash. Some closed canopy pine plantations and Turkey Oak fit in this class. 10 FM10 TIMBER LITTER Fire spreads in surface fuels consisting of litter and / or dead and down stemwood occasionally produced by weather (tornado or hurricane) or other biological impacts such as insect defoliation and mortality. Dry ladder fuels resulting from herbicide application to vine laden treed communities and light slash associated with incompletely harvested timber operations may also contribute to this fuel type. 11FM11SLASHSlash is not continuous. Needle litter or small amounts of grass or shrubs must be present to help carry the fire, but primary carrier is still slash. Live fuels are absent or do not play a significant role in fire behavior. The slash depth is about 1 foot. 12FM12SLASHSlash generally covers the ground (heavier loadings than Model 11), though there may be some bare spots or areas of light coverage. Average slash depth is about 2 ft. Slash is not excessively compacted. Approximately one-half of the needles may still be on the branches but are not red. Live fuels are absent or are not expected to affect fire behavior. 13 FM13 SLASH Slash is continuous or nearly so (heavier loadings than Model 12). Slash is not excessively compacted and has an average depth of 3 ft. Approximately one-half of the needles may still be on the branches and are red. OR all the needles are on the branches but they are green. Live fuels are not expected to influence fire behavior. 97 FM97 NONE Agriculture 98 FM98 NONE Urban 99 FM99 NONE Barren 100 FM100 NONE Water |
