FCCS Fuelbed Field Definitions

An FCCS fuelbed file encapsulates over 100 variables, organized by stratum: general, canopy, shrub, herbaceous, wood, litter-lichen-moss, and ground fuel. This table defines each field, as well as its XML file path and notes regarding valid data.

GeneralFuelbed NumberAlphanumeric number for fuelbed. The original FCCS reference fuelbeds are numbered 0 - 1299. Region 6 disturbance fuelbeds are numbered in the 5,000's. See complete list of FCCS-authored fuelbeds.//fuelbed_numberAlphanumeric
GeneralFuelbed NameIn general, the name of each FCCS reference fuelbed begins with a list of the most important or diagnostic species in the vegetation type that the fuelbed defines. Species in the same stratum are separated by a hyphen and those in different strata are separated by a slash (e.g., Engelmann spruce-subalpine fir/horsetail forest). Vegetation type (e.g., forest, shrubland, grassland) is listed after the species names.//fuelbed_name
GeneralFuelbed DescriptionFuelbed descriptions typically contain the geographic extent of a fuelbed, species commonly associated with the fuelbed, a description of applicable change agents, and any other information important to distinguishing that fuelbed from others.//fuelbed_description
GeneralEcoregion(s)One or more of Bailey's 14 ecoregion divisions (Bailey 1989) (see ID field definitions table for full list)//ecoregionComma-delimited list of IDs (see ID field definitions)
GeneralVegetation FormBroadleaf forest, conifer forest, mixed forest, savanna, shrubland, grassland, or slash. Mixed forests are defined as forests in which evergreen and deciduous species each contribute 25 to 75 percent of total tree cover in both overstory and midstory layers.//vegetation_formVegetation form ID (see ID field definitions)
GeneralStructural ClassOld-forest multistory, old-forest single story, stem exclusion closed canopy, stem exclusion open canopy, young-forest multistory, understory re-initiation, or stand initiation (null if non-forested fuelbed)//structural_classStructural class ID (see ID field definitions)
GeneralSAF/SRM Cover TypeOne or more of Society of American Foresters cover types (Eyre 1980) or Society for Rangeland Management cover types (Shiflet 1994) (see ID field definitions table for full list)//cover_typeComma-delimited list of IDs (see ID field definitions)
GeneralChange AgentOne or more from given list of natural or anthropogenic disturbances or management actions that affect fuelbed structure and composition (see ID field definitions table for full list)//change_agentComma-delimited list of IDs (see ID field definitions)
GeneralNatural Fire RegimeFire frequency/severity regime (see ID field definitions for list)//natural_fire_regimeNatural fire regime ID (see ID field definitions)
