Why It Matters

The shift toward aggressive fire suppression directly impacts how federal agencies manage public lands, the safety of residents in fire-prone areas, and the allocation of billions of dollars in federal firefighting budgets.

Key Facts

  • The '10 a.m. rule' was originally mandated in 1933, requiring all wildland fires to be extinguished by 10 a.m. the day after reporting.
  • The Forest Service officially abandoned the 10 a.m. rule in 1978 after recognizing it led to dangerous fuel accumulation.
  • The 'Wildfire Paradox' describes how suppressing 95-98% of fires leads to more intense, uncontrollable fires later due to fuel buildup.
  • Federal wildfire suppression costs reached $2 billion in 2017, a six-fold increase from the 1990s.
  • The 1994 South Canyon fire resulted in the deaths of 14 wildland firefighters.
  • The 2018 Camp Fire in Paradise, California, resulted in over 80 deaths.
  • Draft versions of the 'Fix Our Forests Act' included language for full suppression of all wildfires.
  • Forest Service Chief Tom Schultz confirmed at a July 22 hearing that the agency is currently prioritizing aggressive initial attack on all wildfires.
