The Thinning Trap

There is a circular logic going on around the issue of fuel buildup and fire suppression. Currently the major federal agencies including the Forest Service and BLM generally attempt to suppress fires, except in a few special locations like designated wilderness. Despite the fact that most agencies now recognize that wildfires have a very important ecological role to play, we are told by managing agencies that they must continue to suppress fires or face “catastrophic” blazes—which they consider to be “uncharacteristic”. The problem is that thinning won’t solve the “problem” of large blazes because the problem isn’t fuels. By allowing the timber industry to define the problem and propose a solution we have a circular situation whereby the land management agencies continue to suppress fires, thereby presumably permitting fuels to build up, which they assert thus drives large blazes, creating a need for more logging and fire suppression. This cycle of fire suppression, logging, grazing, and more fire suppression has no end. In addition, since thinning reduces completion, opens up the forest floor to more light, thus new plant growth, thinning can often lead to creation of even more of the flashy fine fuels that sustain forest fires. Unless these thinned stands are repeatedly treated, they can actually acerbate fire hazard by increasing the overall abundance of the very fuels which are most problematic—the smaller shrubs, grasses, and small trees that sustain fire spread. In addition, thinning can increase solar penetration leading to more rapid drying and greater penetration of wind—both factors that aid fire spread...read more
