Pine Beetle Outbreak Threatens Douglas County Ponderosa Forests

Aerial surveys conducted over the last year showed mountain pine beetles have returned in force, killing ponderosa pines across the Front Range and creating visible pockets of dead trees along major highways. The U.S. Forest Service and the Colorado State Forest Service identified elevated infestation in portions of Larimer, Gilpin, Clear Creek, Boulder, Jefferson, Park and Douglas counties, and foresters warned that mortality caused by beetles can create public safety hazards, change fire behavior and make suppression more challenging for firefighters.

In response, Governor Jared Polis issued an executive order on December 15 creating a Ponderosa Mountain Pine Beetle Task Force and said the state would pursue stronger measures. “Colorado has long been a leader in forest health and fire mitigation efforts, and this is no exception,” Polis said. “As the latest outbreak of pine beetles begins to take shape along the densely populated Front Range, we are taking an aggressive approach to boost tools and partnerships to help protect our communities, forests and key water sources, and equipping homeowners with the resources they need to better protect their homes.” The administration said it will submit a supplemental request to the legislature recommending actions to reduce wildfire risk, support landowners and lower the cost of risk mitigation. Task force members were expected to be appointed by February 1, 2026.

For Douglas County residents the outbreak raises immediate concerns about home safety, local evacuation planning and the visual and ecological effects on nearby open space. Beetle killed stands increase the amount of dead fuel available for wildfire, and concentrated patches of dead trees near roads and utilities can create hazards during storms or when snow loads are high. State foresters advised homeowners to look for signs of infestation including popcorn shaped masses of resin on trunks, fine boring dust lodged in bark crevices, heavy woodpecker damage, visible beetle life stages and small exit holes on bark.

Foresters emphasized that warming temperatures and extended drought have created conditions that favor beetle spread, and that heavy rains and flooding in prior years only temporarily slowed past outbreaks. Officials say proactive mitigation and coordinated state support will be required to protect forests, water sources and the communities of Douglas County as the state moves from assessment to action.
