| Beetle killed spruce on Mt. Dutton - Dead spruce along Cottonwood Cr. Road - U.S. Forest Service Entomologist Steve Munson. |
Living in southern Utah, most are not newcomers to spruce beetle outbreaks affecting both the Dixie and Fishlake National Forest. But even silviculturists (tree experts) and entomologists (insect experts) are newcomers in dealing with these large outbreaks. Like many other events, if we could see back a couple of hundred years, we would probably see a similar situation as with fire – periodic insect events that play a role in forest renewal. |
U.S. Forest Service Entomologist Steve Munson, who has spent much of his career following the small beetle, estimates that an outbreak occurs every 150 to 200 years in a spruce-fir forest. “Whether it is fire or spruce bark beetle that affects the system, it is a naturally occurring event,” says Munson. |
