Forest fire prevention efforts will lessen carbon sequestration, add to greenhouse warming
Date:7/8/2009

figure, however, assumes an optimal production of energy from biofuels that is probably not possible," Harmon said. "By the time you include transportation, fuel for thinning and other energy expenditures, you are probably looking at a return of more like 60-65 percent. And if you try to produce cellulosic ethanol, the offset is more like 35 percent."

"If you take old, existing forests from these regions and turn them into almost anything else, you will have a net loss in carbon sequestration," Harmon said.

That could be significant. Another recent OSU studied concluded that if forests of Oregon and northern California were managed exclusively for carbon sequestration, they could double the amount of sequestration in many areas and triple it in some.

The new study found that, in a Coast Range stand, if you removed solid woody biofuels for reduction of catastrophic fire risks and used those for fuel, it would take 169 years before such usage reached a break-even point in carbon sequestration. The study showed if the same material were used in even less efficient production of cellulosic ethanol, it would take 339 years.

The researchers did not consider in this analysis how global warming in coming years might affect the increase of catastrophic fire, Harmon said. However, "fire severity in many forests may be more a function of severe weather events rather than fuel accumulation," the report authors wrote, and fuel reduction efforts may be of only limited effectiveness, even in a hotter future.

"Part of what seems increasingly apparent is that we should consider using west side forests for their best role, which is carbon sequestration, and focus what fuel reduction efforts we make to protect people, towns and infrastructure," Harmon said. "It's almost impossible anyway to mechanically treat the immense areas that are involved and it's hugely expensive. As a policy question we have to face issues of what approaches will pa
