The Fire Next Time
While we’re facing more wildfires than ever, the federal government wants us to return to outdated firefighting methods.
For more than 100 years, the U.S. Forest Service has been researching, reacting to, and generally trying to understand wildfires, and along the way, our methods have changed significantly. In 1910, the “Big Blowup” destroyed about 3 million acres—roughly the size of Connecticut—in Idaho, Washington, and Montana. The devastation of the Big Blowup, much of which reportedly took place in just 36 hours, cemented the idea of fighting fires aggressively and immediately. In the 1930s, the Selway forest fires in Idaho and Montana led to the “10 a.m.” policy: Try to contain every fire that is reported by the next time 10 a.m. comes around. But in the 1960s and ’70s, foresters began to recognize that fires were important parts of natural systems, and the policy of “fire use” came into play—the idea that local and regional managers could and should allow some fires to burn. That’s partly because in mountainous areas, they are nigh impossible to control, and sometimes it’s deemed too dangerous to send firefighters into a blaze.But they also serve an important purpose: preventing even worse burns. “Thinning the herd,” it seems, happens in the forest—and can actually help build natural hurdles to subsequent blazes.
The 2000s have seen some very bad years for wildfires—in part thanks to a bevy of stupid or reckless human-started blazes—but until this summer the general policy stayed mostly the same: Let forest and land managers make the decisions of what to let burn and what to put out. This year’s shift is a reflection of just how up against the wall we are, nationally, when it comes to resources for fighting wildfires. The scariest part is that things seem to only be getting worse with climate change. A recent climate study published this summer in Ecosphere suggests that over the next 30 years, 38 percent of the planet will see increases in fire activity. By the end of the century, that number is projected to be 62 percent. If this holds true, now may not be the time to go back to fire-fighting techniques popular in the 1910s.
When I wrote earlier this season about the newer technologies we’re now using to fight fires, I spoke with David Calkin, a Ph.D. in economics and a research forester at the Rocky Mountain Research Station in Missoula, Mont. Calkin’s view of forest management is macro, and he doesn’t seem prone to exaggeration. Even when I was pressing him on climate change or how damaging the policy shift could be, he was more likely to talk about the natural progressions of systems than to say that the extreme weather and awesome scope of the burning—which NASA satellites are now monitoring from orbit—were cause for extreme alarm. But there’s no question that he is worried.
“When we look at climate models, some parts of the world are expected to get wetter and hotter, some expected to be drier and hotter,” he said. “But there is a concern that this is a step back. Even in the policy direction it acknowledges that it’s not a good long-term strategy.”
You could almost consider it a surge strategy—like the kind we used in Iraq with, shall we say, mixed success. Throw everything we’ve got at the fires now, to stop it from getting worse. Is there a third way? Until we can make our own rain, cool the climate, and stop shooting live ammo at rocks during drought season, probably not. Even our best technologies and treatments are still relatively puny against Mother Nature.
Any forester will tell you—fire is a part of life. And we’ve got ourselves a firewalker’s dilemma, a choice between setting our shovels against the small stuff and ignoring the smoke of a massive burn on the horizon, or taking the long view. This season, we’ve set our shovels to the small stuff, and lives and housing developments have been saved. But it’s going to set us back in the battle to manage, and to let nature take its course. This season, we’re making the next big burn even bigger.
