A nearly century-old U.S. wildfire policy is facing renewed scrutiny as federal officials weigh aggressive suppression strategies against the ecological risks of heavy fuel accumulation, according to reporting by CalMatters. The debate centers on the U.S. Forest Service’s historical “10 a.m. rule,” established in 1933, which mandated that any new wildfire be suppressed by 10 a.m. the following day.
The policy originated in the wake of the 1910 “Big Burn,” a catastrophic series of fires that consumed over 3 million acres across Montana and Idaho, resulting in at least 85 deaths and destroying five towns. For decades, the federal mandate prioritized absolute containment. However, foresters eventually observed that suppressing every small fire allowed debris, needles, and dead brush—known as fuel—to accumulate. This buildup created conditions for larger, more destructive blazes when fires did break out, leading the agency to introduce “let burn” strategies for low-risk natural fires and officially discard the 10 a.m. rule in 1978.
Political Pressure and Federal Policy Shifts
Pressure to reinstate aggressive early suppression has mounted following major fires, including a destructive blaze in Los Angeles in January 2025. According to CalMatters, President Donald Trump issued an executive order in June 2025 titled “Common-Sense Wildfire Prevention and Response Authority Strengthening,” which cited the Los Angeles fire and criticized state and local governments for slow disaster responses. Drafts of that executive order and early iterations of the federal “Fix Our Forest Act” initially included provisions to revive the 10 a.m. rule or mandate total suppression, though those specific measures were ultimately removed, as reported by CalMatters.
Clashing Perspectives on Forest Management
Wildfire response organizations strongly oppose a return to blanket full-suppression policies. Matt Weiner, chief executive officer of the wildfire advocacy group Megafire Action, told CalMatters that forest ecosystems require beneficial fire and argued that his organization would actively block the inclusion of the 10 a.m. rule in legislation.
Despite pushback from conservation and advocacy groups, current Forest Service leadership remains committed to rapid initial attacks. During a congressional hearing on July 22, Forest Service Chief Tom Schultz stated that the agency prioritizes aggressive responses to new fire starts, emphasizing that a full-suppression strategy applies to all wildfires.
