When initiating a prescribed fire, it is important to determine the type of ignition pattern, or combination of patterns prior to the burn. Making this determination depends on several factors: burning objectives, fuel characteristics, pre- and post-burn weather, smoke management, manpower and equipment availability, and adjacent fuels.
Prescribed fire is a tool utilized under very specific and predetermined conditions to manipulate the environment and achieve a desired outcome. Fires helped to control unwanted pests, and to increase safety around the living areas by increasing the visibility. Learning from the past, land stewards now use prescribed fire in forests to manage vegetation, improve wildlife habitat, and control pest problems.
Prescribed fire is one of a suite of tools used to manage landscapes to achieve specific management goals. Safety in using prescribed fire is of utmost importance. To conduct a safe and effective prescribed fire requires not only a burn plan and clear lines of communication, but also the right equipment and a crew who know how to safely use that equipment and employ the correct firing techniques.

Fire is a critical natural process necessary for maintaining ecosystems around the world, providing a means for renewal, regrowth and maintenance of habitats. In grassland and savanna ecosystems, fire plays an important role by limiting encroachment of wood species and cycling nutrients; however, in nearly all grassland and savanna habitats fire was not the only process at work. Historically, fire was closely coupled with grazing – namely by large mammals.

Oak wilt, the most damaging disease of oak trees in lowa, has killed many forest and landscape oaks in the eastern and central United States. Oak wilt has not devastated its host species, however, mainly because its spread from diseased to healthy trees has been relatively slow and sporadic. Nevertheless, local outbreaks of oak wilt can kill or injure many trees. The management practices described in this publication can help minimize the risk of losing oaks to this disease.

Managing smoke produced by prescribed fires has, in recent years, become a critical consideration when planning a prescribed fire event. In some situations, planning for smoke management may be more complicated than planning for the prescribed fire itself. Considerations such as human and animal health and safety, air pollution, and reduced visibility must be taken into careful account when planning even a small, routine prescribed burn.
