Forest Health and Wildfire Risk Increasing Wildfire Risk The smoke, fire and evacuations that signal Colorado’s fire season are a summer norm, but in recent years, wildfires have grown more frequent, intense, large and destructive. The 20 largest fires in the state’s history have all burned since 2000, with the three biggest ignited in 2020. Before development, wildland fires played a natural, healthy role in many ecosystems. They burned more frequently, thus the intensity and scale of fires was more limited, and they enabled fire-adapted plants and ecosystems to thrive. But today, decades of fire suppression, fuel buildup, development in close proximity to wildlands (known as the wildland-urban interface or WUI), increases in forest insect and disease infestations, and climate change, among other

factors, have caused an increase in size, severity and duration of wildfires. Fires are expected to continue getting worse. A 50% to 200% increase in the area burned in Colorado each year is projected by 2050, according to the 2017 Colorado State Forest Service and Colorado Water Conservation Board report “Forest Management to Protect Colorado’s Water Resources.” Today, fires threaten not only homes, infrastructure and human lives, but also the water that people depend on. Even in mountain forests, away from civilization, blazes can load rivers and reservoirs with sediment, nutrients and toxins, impacting water supplies, river and watershed health, and water conveyances or other infrastructure.
