Western U.S. Wildfires Decline in Number but Intensify in Scale
Western U.S. Wildfires Decline in Number but Intensify in Scale
US · Published Jun 4, 2026
Recent research highlights a paradox in wildfire trends across the western United States.
While the total number of wildfires has decreased by 31% between 1992 and 2020, the acreage burned has surged by 40%, according to a study led by Amirhossein Montazeri, a PhD student at Boise State University.
The study, published in Environmental Research Letters, analyzed over 750,000 wildfires and found that human-caused fire starts have dropped by 33%, likely due to successful prevention campaigns.

Why It's Important?

The intensification of wildfires poses significant risks to ecosystems, communities, and infrastructure across the western U.S. Larger and more intense fires can lead to greater destruction of property, displacement of residents, and loss of wildlife habitats. The study underscores the role of climate change in creating conditions conducive to rapid fire growth, such as reduced fuel moisture and extreme weather thresholds. These trends highlight the need for adaptive land management strategies to mitigate risks, including the use of prescribed burns and targeted fire suppression efforts during critical periods.
