REPORT: Pine beetle destruction expands dramatically on Front Range
"Aerial survey data from the USDA Forest Service and CSFS show that mountain pine beetles are spreading in ponderosa pine forests on the Front Range. These forests contain highly populated, high wildfire risk areas with many trees susceptible to this native insect. Mountain pine beetles impacted 5,544 acres of pine forests in a nine-county area of the Front Range in 2025, compared to 2,236 acres across this same area in 2024 – a 148% increase."
“What we’re seeing with mountain pine beetles along the Front Range isn’t cause for panic, but it is a reminder to stay vigilant and get to work,” said Matt McCombs, state forester and director of the Colorado State Forest Service. “Using good science and strong partnerships, we can build forests and communities that are more resilient in the long run.”
Colorado’s top forest health concern is a mountain pine beetle outbreak on the Front Range that has expanded by nearly 150% from 2024 to 2025, according to a Colorado State Forest Service report.
