FRISCO —Bark beetles have already killed millions of acres of mid-elevation forests across the West, and warming temperatures are enabling the tree-killing bugs to invade higher elevations, where they are attacking trees that haven’t evolved with strong defenses to repel them.
Global warming is essentially giving the insects a huge advantage, as the trees, with their long lifespans, have no chance to develop biological resistance, according to researchers from the the University of Wisconsin-Madison, who report a rising threat to the whitebark pine forests of the northern Rocky Mountains.
