A research project on forest lands in the mid-Atlantic region was performed with the dual goals of testing which of the 13 Anderson fuel models most accurately depicts common understory fuel characteristics in these forests, and what proportion of advance regeneration of desired species will sprout after burning. The work covered a range of public forest lands, and varying types of fuels and different burn intensities. Researchers found that, overall, one or more of the Anderson fuel models accurately portray most of the fuel conditions found on the experimental areas. However, no fuel model appears to represent evergreen heath shrubs such as mountain laurel. They believe this is true for the entire central Appalachian mixed-oak region. Evaluation of sprouting potential indicates variability in sprouting with the size and location of the root collar, and the duration and intensity of the fire.
