Report: Forest Beetles Not to Blame for Big Western Fires

PHOENIX - Major wildfires in the forest backcountry of the West are often blamed on pine bark beetles, and a common assumption has been that those diseased and dead trees present a higher fire risk. However, according to a new report from the National Center for Conservation Science and Policy, beetle outbreaks are not directly related to higher fire risks.

Report author Dr. Dominick Kulakowski, a professor of geography and biology at Clark University, says the research showed that drought and higher temperatures fuel backcountry fires - not beetles.

"And, in fact, drought conditions are so important to the occurrence of wildfires, that whatever effect that bark beetles outbreaks have are largely overridden."

The report suggests that the limited money available to reduce forest fire risk be spent on protecting communities at the edge of the forests, which Kulakowski believes are more cost-effective than backcountry tree-cutting projects.

"The best strategy is to clear away fuels and other flammable material from the vicinity of our homes, and make sure that we use non-flammable materials on our homes as much as possible."

Western forests are seeing the biggest beetle outbreaks in decades, with millions of acres of ponderosa, lodgepole and pinon pines killed. The full report, "Insects and Roadless Forests: A Scientific Review of Causes, Consequences and Management Alternatives," is online at http://nccsp.org.
