“Total fire suppression,” the official policy in the Southern California mountains since 1919, has been a tragic error because it creates enormous stockpiles of fuel. The extreme fires that eventually occur can transform the chemical structure of the soil itself. The volatilization of certain plant chemicals creates a water-repellent layer in the upper soil, and this layer, by preventing percolation, dramatically accelerates subsequent sheet flooding and erosion. A monomaniacal obsession with managing ignition rather than chaparral accumulation simply makes doomsday-like firestorms and the great floods that follow them virtually inevitable.
