What happened

Pine beetle damage expanded along Colorado's Front Range by an exponential amount between 2024 and 2025 amid a new outbreak, according to a newly released report from Colorado State Forest Service.

Why it matters

The 2025 Report on the Health of Colorado's Forests revealed that mountain pine beetles, which have plagued the Front Range for years, expanded nearly 150% between 2024 and last year.

Common ground

Notably, the report found that a new outbreak of these beetles, which are native, is currently spreading in ponderosa pine forests that are already at high risk of wildfires.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
