FORT COLLINS, Colo. — The latest findings about the health of Colorado’s forests are a “mixed bag”, according to forestry experts. On Tuesday, the Colorado State Forest Service released its annual report tracking the damage from forest pests. “Insects are so closely tied to a lot of that temperature and precipitation so in Colorado it’s really been a number of years, actually 31 years, since we’ve been below average temperatures so that makes it really hard to be a tree in Colorado,” CSFS forest entomologist Dr. Dan West said. …According to the report, the front range is experiencing a surge in activity from the mountain pine beetle. In 2021, the insect impacted 1,500 acres statewide. In 2024, that number grew to 5,600 affected acres and included areas in Jefferson County and Castle Rock. …Not only do the dead trees cause forests to be less visually attractive, but they also create more fuel for more damaging wildfires.
