Wildfire management

A wet winter and spring followed by a hot, dry summer can be a dangerous combination in the Western U.S. The rain fuels bountiful vegetation growth, and when summer heat dries out that vegetation, it can leave grasses and shrubs ready to burn. Drier than normal conditions, like many regions are experiencing in 2024, also raises the fire risk. In years like this, controlled burns and prescribed fire treatments are crucial to help protect communities against wildfires. Well-staffed fire crews ready to respond to blazes are essential, too.

However, taken at face value, budget cuts could be interpreted as a reductio...

As wildfire risk rises in the West, wildland firefighters and officials are keeping a closer eye on the high mountains – regions once considered too wet to burn. The growing fire risk in these areas became startling clear in 2020, when Colorado’s East Troublesome Fire burned up and over the Continental Divide to become the state’s second-largest fire on record. The following year, California’s Dixie Fire became the first on record to burn across the Sierra Nevada’s crest and start down the other side. We study wildfire behavior as climate scientists and engineers. In a new study, we show that fire risk has intensified in every region across the West over the past four decades, but the sharpest upward trends are in the high elevations.

It can be tempting to think that the recent wildfire disasters in communities across the West were unlucky, one-off events, but evidence is accumulating that points to a trend. In a new study, we found a 246% increase in the number of homes and structures destroyed by wildfires in the contiguous Western U.S. between the past two decades, 1999-2009 and 2010-2020. This trend is strongly influenced by major fires in 2017, 2018 and 2020, including destructive fires in Paradise and Santa Rosa, California, and in Colorado, Oregon and Washington. In fact, in nearly every Western state, more homes and buildings were destroyed by wildfire over the past decade than the decade before, revealing increasing vulnerability to wildfire disasters. What explains the increasing home and structure loss? Surprisingly, it’s not just the trend of burning more area, or simply more homes being built where fires historically burned. While those trends play a role, increasing home and structure l...
