Catastrophic wildfires have become a fact of life in the West—and they threaten not just the lives and homes of humans, but the health of the planet. We take a deep dive into the numbers behind wildfire and how to manage it.

Y

es, Colorado may be boasting a near-record snowpack this season, but that doesn’t mean wildfires aren’t going to be a concern for our state, which historically dries out quickly during summer. Here’s the good news: According to the National Interagency Fire Center, which publishes the “National Significant Wildland Fire Potential Outlook” report, large portions of Colorado will carry below normal fire potential at least until August. But as wildfire season approaches, it’s key to remember how devastating a blaze can be, especially along the wildland-urban interface, which in our state houses some 2.9 million residents. Here are the numbers on recent fires, fire destruction, and the federal government’s fiscal and physical commitment to fighting them. Read them with a little relief—and keep your fingers crossed for a safe summer—but withhold a steady dose of caution. Any fire could bloom into a big one, and in the wrong corridor in Colorado, that could be catastrophic.
