Forest fires caused by lightning once played a major role in forming and maintaining much of Florida’s palmetto-pine flatwoods, sandhills, scrub, prairies and wetlands ecosystems. Many species of wildlife benefit greatly from fire. Historically, Native Americans, farmers and ranchers practiced controlled burning to clear land and initiate new plant growth for wildlife and livestock. But over time, as more people moved into Florida, development began to take over and fragment many natural areas.
Prescribed fire is the best and most cost-effective tool the Florida Fish and Wildlife Conservation Commission’s wildlife managers have for managing wildlife habitat, especially large tracts. Safely-controlled prescribed fire techniques to improve and maintain habitats for deer, quail, turkey and many other wildlife species, have been used for some 75 years.
Some people worry that animals are harmed by prescribed fire. However, the slow-moving flames of carefully planned burns allow animals time to find shelter or move away from the approaching fire. Fire enables habitats to produce enough of the right kinds of food for wildlife by promoting nutritious, tender new growth of plants as well as increasing the production of seeds and fruit. This new growth attracts many insect species, which are great sources of protein for turkey and quail.
Periodic controlled burns also reduce the danger of devastating wildfires developing because the buildup of underbrush on the forest floor has been removed. Prescribed fire is the best way to eliminate such flammable debris, which helps lower the risks of wildfires forming and reduces their intensity if they do occur. Burning also allows animals to move through areas that would otherwise be impassable and unusable.
Controlled burns release and recycle nutrients back into the soil and allow more sunlight to reach the ground. This stimulates seeds to sprout, which produces tender, low-growing vegetation that provides food and appropriate shelter for wildlife. Prescribed fire also reduces the number of parasites and pests such as ticks.
Rigorous training and mandatory safety gear ensure that safety is the top priority for burn crew staff and the public on every prescribed burn the FWC conducts. Controlled burns are planned months in advance by skilled teams of experienced wildlife biologists and land managers who identify and prioritize areas that need it the most. Each burn unit has a specific plan, or “prescription,” that describes the area to be burned, optimal weather conditions, humidity levels and wind direction, personnel and equipment needed, and specifics necessary to conduct a safe and effective burn. When weather conditions are appropriate, the FWC obtains a burn authorization External Website from the Florida Forest Service External Website and notifies people living nearby before starting a burn.
The FWC conducts prescribed burns at various times of the year to produce the best-desired results. Burning during the spring and summer increases the growth of native grasses and hardwoods. Burning during the winter is less damaging to shrubby plants.
When conducting a prescribed burn, the FWC makes every effort to minimize impacts to the public. You might see smoke plumes travelling high into the air, where they quickly dissipate. It is normal for the area around a burn to smell smoky for a day or two.
Right after a prescribed burn, the area may appear charred and bare but will attract deer and turkey, which can often be found in a burned area the very next day. A few weeks to months following, the area will be lush with all kinds of thriving wildlife. By using prescribed fire as a management tool, the FWC can keep Florida’s wildlife populations and their habitats healthy.
