Fuel stratumn. A horizontal layer of a fuel complex.
Six fuel strata are generally recognized: tree, shrub, non-woody vegetation (grass and herbs), woody vegetation, litter/lichen/moss, and ground (duff). Together, these fuel strata comprise a fuel complex. Characteristics associated with each fuel stratum provide inputs to fire behavior, fire effects, and carbon accounting models.
