understory type and density, was then added to the fuel class (Table 7). For example, polygons with an understory of light density Kalmia latifolia (mountain laurel), an evergreen understory shrub that usually grows on dry, south-facing slopes, were assigned a decimal value of 0.1 and medium density mountain laurel a value of 0.3. The overstory-based fuel class integer value (1 through 13) added to the understory- based decimal value provides fire managers with a maximum amount of information on fuel conditions that considers both overstory and understory vegetation (Figure 17).
