On a calm summer evening in the mountains around Steamboat, the forest can look perfectly healthy. Tall spruce and fir cast long shadows across the ground, young trees fill the spaces between older ones, and fallen branches slowly return to the soil. To most people, it looks natural and untouched—the way a forest should be.
But from a forest management perspective, what looks natural can sometimes be a warning sign. In many parts of Routt County, the greatest wildfire risk isn’t what people do to the forest; it’s what happens when nothing is done at all.
Forests in northwest Colorado evolved with regular disturbance. For thousands of years, fires, insects, windstorms, and other natural forces periodically reshaped the landscape. These disturbances thinned forests, cleared dead material, and created a mix of different tree ages and densities.
Wildfire played an especially important role. Smaller, lower-intensity fires once moved through many forests, clearing out brush and young trees while leaving larger trees standing. The result was a more open forest structure with less continuous fuel.
Today, those natural processes occur far less frequently in the wildland–urban interface (WUI), where homes and forests meet. Fire suppression over the past century has been extremely effective at protecting homes and communities, but it has also changed how forests grow. Without periodic disturbance, forests become crowded with small trees and dense vegetation. Dead branches accumulate, shrubs grow thick in the understory (layer of vegetation below the main forest canopy and above the forest floor), and fallen trunks build up on the forest floor.
Over time, these conditions create what foresters call heavy fuel loading. These landscapes provide poorer habitat for wildlife such as bears, elk, deer, and moose, and they produce hotter, faster-moving wildfires that are increasingly difficult to suppress.
This matters especially in Routt County, where much of the housing lies within the wildland–urban interface. In these areas, wildfire risk isn’t just about the forest itself. It is also about how fire can move from vegetation to structures and from one structure to another.
When forests become overly dense near homes, they can create a vertical ladder of fuel. Grasses and shrubs ignite easily, flames reach young trees, and those trees allow fire to climb into the canopy. Once a fire reaches the canopy, it can spread rapidly and produce embers that travel long distances in the wind. Those embers are responsible for many home ignitions during wildfires.
The goal of forest management is to mimic the historical disturbances that once shaped these forests. For thousands of years, periodic fires naturally thinned trees, reduced fuel, and maintained a more open forest structure. Today, however, the forests around Steamboat experience intense fire suppression activities to protect homes, preventing the natural thinning process that once maintained these forests.
Active management helps restore some of those natural patterns. Strategic thinning and fuel reduction remove excess trees, reduce dense patches of vegetation, and clear dead material from the forest floor. The goal isn’t to clear the forest, but to recreate historical conditions in which forests are healthier, and wildfires burn with lower intensity.
While these treatments reduce wildfire intensity across the broader landscape, the final and most important line of defense is the area immediately surrounding homes. Creating defensible space by clearing flammable vegetation, spacing trees, and removing dead material can significantly reduce the chances that a wildfire will ignite a structure.
Living in the forest is a privilege that comes with responsibility. Protect your home and community by creating defensible space around structures, regularly removing flammable vegetation and dead material, properly spacing trees, and supporting local active forest management efforts. Take proactive steps now to reduce wildfire risk—delay increases the threat each year.
Active management keeps forests, wildlife, and communities resilient.
