Controlled Burns Save $3.73 for Every Dollar Spent

Scientists just put a number on what Indigenous communities have known for centuries: controlled fires work, and they're worth every penny.

A study published in Science analyzed 285 wildfires across 11 Western states and found that for every dollar the U.S. Forest Service spends on clearing underbrush and prescribed burns, taxpayers avoid $3.73 in damage. That includes health costs from smoke, destroyed buildings, and carbon emissions.

The research tracked wildfires from 2017 to 2023 that burned through areas where the Forest Service had already reduced fuel loads. These treated areas saw 36 percent less total burning and 26 percent less severe damage compared to untreated land.

Frederik Strabo, an economist at UC Davis who led the study, says the savings are real and measurable. Fuel treatments prevented $1.39 billion in health and productivity losses from wildfire smoke, $895 million in structural damage, and $503 million in carbon emissions.

The research also revealed that bigger is better. Treatments covering more than 2,400 acres delivered the most bang for the buck.

Morgan Varner, director of fire research at conservation nonprofit Tall Timbers, called the work "the missing link" in understanding fuel treatment benefits. Data like this helps decision makers see the full picture of why these practices matter.

The Bright Side

While critics debate whether public lands management effectively protects nearby homes, researchers found encouraging evidence. Fires that burned through treated areas were often the most economically consequential, meaning the treatments likely prevented even worse disasters.

The 2021 Caldor Fire near Lake Tahoe serves as a powerful example. The fire still caused substantial damage, but treatments helped keep it from becoming catastrophic.

Not every expert agrees on the exact math, and some worry about assigning dollar values to things like ecosystem health and public recreation access. But even skeptics acknowledge the core finding: fuel treatments work.

The approach mirrors practices Indigenous nations have used for centuries to manage landscapes. Scientists are finally catching up with ancient wisdom, armed now with data to prove what traditional knowledge keepers always understood.

Recent shifts in federal forest management have reduced the number of acres treated in 2025 compared to 2024. But the science makes a compelling case for investing in prevention rather than just fighting fires after they start.

The study didn't even capture all the benefits, like savings to the outdoor recreation industry or long-term ecosystem health improvements.
