Fuel complex

n. The combination of all fuel strata present at a site.


  • Discussion


A fuel complex is composed of up to six fuel strata: tree, shrub, non-woody vegetation (grass and herbs), dead woody, litter/lichen/moss, and ground (duff). A fuelbed, as defined in the Fuel Characteristic Classification System (FCCS), is a description of all six fuel strata that comprise a fuel complex. Other fire management applications describe a fuel complex by the separate fuel strata. For more information on the FCCS, please refer to Ottmar and others (in press).
