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