Massive Infestation of Beetles Threatens Mountain Pines in Western U.S.

Adult mountain pine beetle (Dendroctonus ponderosae) responsible for millions of acres of devestated pine forest. A major infestation of the mountain pine beetle, a scourge stretching from New Mexico, in the U.S., to British Columbia, Canada, has been turning vast areas of formerly green pine forests to rust red, and slowly killing them.

The beetle infestation has been growing “exponentially” since 2006-07, according to the Forest Service management team in Laramie, Wyoming, and has so far claimed millions of acres of pine forest in Montana, Colorado, and Wyoming. North of the border, British Columbia has already lost over 33 million acres of lodgepole pine forest due to the ravages of this type of bark beetle. And more recently (in 2008), Alberta province is come under threat due to an aberrant wind storm that apparently lofted the beetles across the continental divide.

Should We Pursue Biofuels From Beetle-killed Wood?

[This is the second half of a story about the pine beetle epidemic in Colorado and what is being done to mitigate its damage. Part one can be found by following this link to sustainablog.]

Residents of Colorado are witnessing a rapid destabilization of the forest around them, and they can do very little to stop it. The spread of the mountain pine beetle epidemic is now considered of ‘catastrophic’ proportion. Most foresters agree that the beetle will essentially run its course by eliminating its favorite food - the lodgepole pine. The most one can hope for is to mitigate fire risk by pursuing aggressive thinning programs. However, thinning forests does not come cheap: it is labor intensive, resource intensive, geo-politically awkward, and the end product is not held in very high regard by the market. But the economic viability of large-scale thinning projects is changing, and it is doing so almost as quickly as the trees themselves are changing from green to red.

This week, several stories hit the newswire that, taken collectively, hint at the growing conditions for a perfect storm for cellulosic ethanol. The ‘virgin’ biofuel industry got a kick in the seat yesterday when a study published in Science confirmed many environmentalists belief that ethanol from corn and switchgrass could actually worsen

Pine Beetles Cross the Continental Divide

While the situation may seem bleak at the outset of this story, I promise some good news in part two before all is said and done.]

Colorado has 1.7 million acres of lodgepole pine forests. Though, if you have any desire to see any of those trees alive, I’d suggest you move rather quickly. State and federal officials recently announced that the mountain pine beetle epidemic grew by a half a million acres in 2007, bringing the total infestation in the state to about 1.5 million acres. Foresters indicated that the epidemic would virtually eliminate every acre of lodgepole pines in the next three to five years.

Up until quite recently, the pine beetle epidemic in Colorado was limited to a five county area along the Continental Divide. However, recent forest surveys indicate that the beetle has crossed the Divide and is moving eastward. The Forest Service’s annual surveys that are produced by ’stitching’ together aerial photographs have enabled the forest service to illuminate the rapid acceleration of the beetles’ northeasterly march. Once restricted to high country hamlets like Breckenridge, Fraser and Steamboat Springs, the hungry beetles are quickly moving into the foothills and front range near Denver, Boulder and Fort Collins. According to Kyle Patterson at Rocky Mountain National Park, the pine beetles have reached “epic proportions.”
