Suppression Firing
The unmeasured variable in American fire science: what is known, what is not, what it costs us, and what the agencies can do about it now.
American wildland firefighters deliberately ignite fire inside wildfire perimeters as a routine tactic. The practice is required by doctrine, taught in a national curriculum, equipped with an expanding arsenal of aerial delivery systems, and conducted at a scale nobody counts. The acres it burns enter the national wildfire statistics without a label. The fire it produces is not distinguished from free-spreading fire in any dataset researchers use. Its effects on soils, old trees, water, air, and listed species have never been measured against a control, in any fuel type, anywhere.
