Different viewpoints explain the observation of secondary burns that follow closely after an initial fire. (1) Reburn results when falldown of the old burned forest contributes significantly to the fire behavior and fire effects of the next fire (Brown et al., 2003). (2) Karr et al. (2002), quoting a report by Everett, remind the House of Representatives that slash from salvage is just as likely to produce reburn: “The Everett Report (p. 5) also states that current research suggests that salvage logged areas may have elevated fire hazard over unlogged sites for the first twenty years after logging.” (3) The rapid release of previously suppressed understory growth and germination of new plants after a fire is also responsible for reburn, as noted by Everett et al. (1999): “once a vegetation has been created that burns more readily than previous plant assemblages, the probability for reburn is increased.” (4) Paysen et al (2000) added that this can occur from needle drop as well as woody debris: “Postburn accumulation of fuel is rapid as most grasses, shrubs, and palmetto resprout within a week of the burn regardless of the season.”
