Fire Risk To Homes Where Cities And Wildlands Meet

Since January 7, wildfires have been devastating the Los Angeles area. In the span of 10 days, several different fires, including the Palisades and Eaton fires, have burned more than 40,000 acres and destroyed more than 12,000 structures. At least 25 people have died.

The threat of fire is growing, especially in zones known as the wildland-urban interface, or WUI. That’s where unoccupied wildland and human developments meet and mingle. Think of a city sprawling around a forest, for example. In the US, around one in three homes is in this type of high-risk zone.

So what’s the science behind urban fires? And how do we protect ourselves in the face of them?

Ira Flatow talks with Dr. Kimiko Barrett, senior wildfire researcher and policy analyst at the research group Headwaters Economics in Bozeman, Montana; and Dr. Alexandra Syphard, senior research scientist at the Conservation Biology Institute in San Diego, California.

Transcripts for each segment will be available after the show airs on sciencefriday.com.
