Column: Can We Slow the Spread of Fire? Eliminating Palm Trees is Essential

In the aftermath of devastating wildfires in Southern California, a renewed focus on landscaping and tree selection is emerging as communities begin to rebuild. The recent Palisades and Eaton fires have raised critical questions about which types of trees can enhance safety while still contributing to the aesthetic and ecological value of neighborhoods.

Kathryn Barger, a member of the Los Angeles County Board of Supervisors, recently sparked a discussion about the role of trees in community life, stating, “trees do make a community.” However, in light of the fires that have ravaged local areas, many experts are advocating for a more cautious approach to urban forestry.

The consensus among fire ecology specialists is clear: structures, rather than vegetation, are often the primary fuel for wildfires, ignited by windborne embers. As neighborhoods look to recover, experts emphasize the importance of hardening homes against fire and incorporating fire-resistant landscaping to create a buffer between properties and potential flames.

Diana Nicole, an ecological horticulturalist, pointed out that the right vegetation can serve as a protective barrier. She and other experts recommend focusing on planting trees that are more resilient to fire, such as California live oaks and sycamores. These species are known for their moisture content, which can help them resist ignition and potentially protect homes from burning embers that might otherwise enter through vents or windows.

Alexandra Syphard, a research scientist specializing in fire ecology, highlighted the importance of maintaining healthy vegetation around homes. “You don’t need to moonscape your property,” she said, advocating for a balanced approach that includes both vegetation and clearings to facilitate firefighter access during emergencies.

The recent fires have also brought attention to the dangers of certain tree species. Experts have warned against planting highly flammable trees like Mexican fan palms and eucalyptus, which can exacerbate fire risks. San Diego landscape architect Kay Stewart noted that these trees can act like “tiki torches,” sending sparks flying during a blaze.

As communities begin to rebuild, discussions about tree selection are becoming increasingly relevant. Many residents are grappling with the loss of familiar landscapes while also considering the need for safety. Cristhian Mace, a biologist with the Eaton Canyon Natural Area, shared observations from the fires, noting that some native trees survived while buildings were destroyed.

Moving forward, experts recommend incorporating a variety of fire-resistant plants, such as toyon, lemonade berry, and lilac, into landscaping plans. These choices not only enhance fire safety but also contribute to biodiversity and the overall health of the local ecosystem.

As the rebuilding process unfolds, it is clear that the decisions made today regarding tree planting and landscaping will have lasting impacts on the resilience of communities in the face of future wildfires. The challenge lies in balancing the aesthetic and ecological benefits of trees with the pressing need for safety in a changing climate.
