CHEYENNE, Wyo. — An outbreak of spruce beetles continues to accelerate across hundreds of square miles of new forest in Colorado, although a much larger outbreak of the similar mountain pine beetle continues to slow across Wyoming, Colorado and the Black Hills, according to a new survey by the U.S. Forest Service.
Every year, the Forest Service conducts an aerial survey of forests in Colorado, Wyoming and South Dakota. The 2013 survey shows spruce beetles spreading to ever-larger expanses of new forest in Colorado for a fifth consecutive year.
