To me there’s no greater irony than that,” Cohen said. “Ironically, we have this high-tech, European culture coming into the land of low-tech … and suddenly we find ourselves today not being compatible with fire as Native Americans were in the Great Plains. Whereas Native Americans used fires to replenish vegetation, that symbiosis disappeared as Europeans spread across North America. At the same time, frequent fires in some suburban foothills have allowed invasive, fast-burning plant species to encroach on homes, which are proliferating across the West’s mountain regions.Īccording to a 2017 study in the Proceedings of the National Academy of Sciences, home building in the wildland-urban interface increased 41% nationwide between 19 - to 41.3 million homes. If a home is ablaze and is close enough to a neighbor - as is the case in most foothill communities across California and the West - there’s a chance a single infected house could turn into an epidemic.Ī former hotshot firefighter, Cohen sees climate change and human folly combining to create ever-more dangerous wildfire conditions.Ī century of aggressive fire suppression has left forests thick with spindly trees and brush, dried out by drought and steadily increasing temperatures. Fire-resistant construction materials and well-maintained landscaping can prevent fires from spreading. Unfortunately, the steps also are within arm’s reach of a thicket of 6-foot-high plants entangled in the wood fence, providing another path for flames to spread to the structure with one inopportune wind shift.ĭetails matter in protecting homes from firebrands.įine wire mesh vent screens help keep out embers. The embers could spark a small fire that could burn the garden’s dead under-story, then spread to the wood fence that overlaps with the gravel and crawl to the home’s siding like a slow-burning fuse.Ĭohen then walked to a back corner of the property, where wood steps connected to the home jut out, providing a gorgeous view of the neighborhood. He crouched, pushed his hand between green plant leaves and grabbed a handful of dead and dying vegetation layered beneath - kindling that could feed a fire. It’s in areas like these across the West, where suburban life flirts with the edge of untamed wildland, that traditional, modern firefighting methods such as aircraft bombardment and clearing land for fuel breaks have failed to stop the worst wind-driven blazes.Ĭohen’s grim diagnosis started just inside the front yard of the Yusi property, where he pointed out a 10-inch-wide gravel strip between the home and the garden. Afterward, he toured the Palisades - where expensive residences are situated on steep hillsides of bone-dry chaparral overlooking Pacific Coast Highway between Malibu and Santa Monica - to assess the risk and provide guidance.

Which led her to join a class being taught by Cohen over the summer.Ĭonsidered by many to be the godfather of wildfire home ignition science, Cohen traveled this summer to Los Angeles from his home in Missoula, Mont., to conduct a three-day mitigation session for residents and firefighters. “Unless you try, you’re not going to get there.”

“It’s going to take every individual person having that commitment,” said Beth Burnam, 62, who leads the North Topanga Canyon Fire Safe Council and has worked to educate her neighbors for years. Launching a group effort can be more difficult than individually protecting homes, but increasingly, communities are banding together to do just that. “That’s where I’m an advocate for coding … so you don’t get a high level of contagion from house to house,” Cohen said of the community’s layout.
