GAINESVILLE, Fla. — Forest managers would prefer to use prescribed burns every few years to help prevent costly wildfires and rebuild unhealthy ecosystems, but hurdles like staffing, budget, liability and new development hinder them, a new University of Florida study shows.
Fighting wildfires is costly. The U.S. government now spends about $2 billion a year just to stop them, according to the National Interagency Fire Center. That’s up from $239 million in 1985.
Leda Kobziar, an associate professor of fire science and forest conservation in UF’s School of Forest Resources and Conservation, led a web-based survey of 523 public and private land managers across Region 8 of the U.S. Forest Service, which consists of 13 Southern states, including Florida. She and her colleagues wanted to see whether front-line experts think prescribed burns prevent wildfires and maintain vegetation and healthy ecosystems. And if they do, what are the circumstances under which such burns work best.
As it turns out, prescribed burns should be done every few years to prevent wildfires or reduce their severity, depending on weather and the type of ecosystem land managers are trying to protect, according to the survey.
