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

CORVALLIS, Ore. Widely sought efforts to reduce fuels that increase catastrophic fire in Pacific Northwest forests will be counterproductive to another important societal goal of sequestering carbon to help offset global warming, forestry researchers at Oregon State University conclude in a new report.

Even if the biofuels were used in an optimal manner to produce electricity or make cellulosic ethanol, there would still be a net loss of carbon sequestration in forests of the Coast Range and the west side of the Cascade Mountains for at least 100 years and probably much longer, the study showed.

"Fuel reduction treatments should be forgone if forest ecosystems are to provide maximal amelioration of atmospheric carbon dioxide over the next 100 years," the study authors wrote in their conclusion. "If fuel reduction treatments are effective in reducing fire severities in the western hemlock, Douglas-fir forests of the west Cascades and the western hemlock , Sitka spruce forests of the Coast Range, it will come at the cost of long-term carbon storage, even if harvested material are used as biofuels."

The study raises serious questions about how to maximize carbon sequestration in these fast-growing forests and at the same time maximize protection against catastrophic fire.

"It had been thought for some time that if you used biofuel treatments to produce energy, you could offset the carbon emissions from this process," said Mark Harmon, holder of the Richardson Chair in the OSU Department of Forest Ecosystems and Society. "That seems to make common sense and sounds great in theory, but when you actually go through the data it doesn't work."

Using biofuels to produce energy does not completely offset the need for other fossil fuels use and completely negate their input to the global carbon budget, the researchers found. At the absolute maximum, you might recover 90 percent of the energy, the study said.
