B.C. pine beetles now killing spruce trees

B.C. Canada

June 28, 2007
Starving mountain pine beetles in central British Columbia have moved into spruce trees as the supply of lodgepole pines disappears. Although spruce are generally not nutritionally or chemically suitable for the beetles to reproduce, they still do enough damage to kill the trees. Last year, more than 9.2 million hectares of B.C. and Alberta forest were in an advanced stage of attack from the tiny, but voracious beetles. As they seek new food sources they are moving east. The worry is that the beetles will soon hit the mother lode of pine trees in the boreal forest. If the beetles jump from the lodgepole pine to the boreal forest's jack pine, an infestation could wipe out billions of trees all the way to the East Coast
