The Tillamook Burn: Four Fires and Oregon's Schoolchildren

August of nineteen thirty-three was the driest summer in memory in the Coast Range east of Tillamook. The Douglas fir stands were old-growth, dense and tall, and the logging operations working through them had left the forest floor covered in slash, the branches and debris from felled trees, bone-dry under a summer sun. On August fourteenth, a logging cable rubbing against a dry log generated enough friction to start a fire. Ten days later, approximately two hundred forty thousand acres of old-growth timber had burned.

That was the first Tillamook Burn. A second fire swept through the recovering forest in nineteen thirty-nine, a third in nineteen forty-five, and a fourth in nineteen fifty-one, each burning portions of the same three hundred fifty thousand acres, each resetting the recovery. By the time the fourth fire was contained, the Tillamook State Forest had burned, in whole or in part, four times in eighteen years.

The recovery campaign that followed is one of the larger organized conservation efforts in American history. Beginning in the nineteen forties, schoolchildren across Oregon were mobilized as tree-planters. Over a generation, millions of seedlings were planted by hand across the burn, and young volunteers on school outings accounted for roughly a million of them. The campaign was organized, sustained, and successful. The forest grew back.

What those schoolchildren could not undo was the root cause: the logging industry's practice of extracting timber without managing the fire risk created by the debris left behind. The slash piles that fed the first fire were a predictable consequence of the extraction method. The conditions that produced the Tillamook Burn were not an accident. They were a business model.
