A prescribed fire is a planned fire—sometimes called a controlled burn—used to manage certain types of landscapes. It reduces the chance of major wildfires and provides numerous other benefits for humans, plants, and wildlife.
Fires play a vital role in keeping certain types of forests, grasslands, and other landscapes healthy. These ecosystems evolved to tolerate semi-regular fires and flourish in their aftermath; despite this, land managers spent much of the 20th century focusing on preventing fire at all costs. But without fires, forests became thick with accumulated branches, leaves, and other organic matter—and this underbrush was fuel for big, deadly wildfires that raged across the United States.
Recognizing this mistake (and the looming threat of climate change), in recent years land managers have embraced prescribed fire—setting intentional, controlled fires set in a specific area with a specific goal—as a necessary and useful tool to prevent dangerous wildfires and manage certain landscapes for long-term ecological health. This guide provides links to resources that offer more detailed information about prescribed fire: how and why it works, crucial elements of safe and effective prescribed burns, and more.
By removing dead and overgrown vegetation, prescribed fires help prevent large, intense wildfires that claim lives, destroy communities, and cost billions of dollars in damage and firefighting costs. Prescribed fires also offer other significant benefits for landscapes, humans, and wildlife:
The following resources further explain the benefits of prescribed fire for humans, plants, and wildlife.
Prescribed fires are dangerous and complicated and may not be suitable for some landscapes. Land managers should consult with an expert before conducting a prescribed fire. Find expert Pennsylvania service foresters and consulting foresters here.
The following resources provide information about how to conduct a safe, effective prescribed fire.
(Note: States have different rules governing prescribed fires. In Pennsylvania, prescribed fires are subject to the regulations in the Pennsylvania Prescribed Burning Practices Act.)
