The noble and heroic 'paradigm' in wildland fire protection is the firefighter who protects forest and other wildlands from attack by fire. The driptorch-lugging prescribed burner carries few of the heroic trappings of suppression personnel. In this paper, we describe the…

Florida's natural communities evolved under the influence of frequent, low-intensity lightning fires. Many communities require such fires for continued existence. Fire managers must contend with the increasing pressure of a burgeoning population. The state's population increases…
