The Palisades Fire that swept through southern California in January of 2025 led to not only the destruction of numerous buildings and homes, but also a large population of trees, according to an article by the Los Angeles Times. Although many of the trees have since recovered, researchers from UCLA recently discovered that nearly 20% of surviving street trees have already disappeared since the fires, raising concerns about the long-term loss of shade, cooling, air quality, and neighborhood character.
Several possible reasons have been proposed, such as insufficient efforts by local governments to ensure the trees are watered, mistakes in identification of dead trees by debris removal crews, and rapid removal for construction.
Edith de Guzman, a researcher at the UCLA Luskin Center for Innovation investigating the trees affected by the fires, found these numbers concerning, as their study was focused only on public spaces, where the trees should have been under the protection of the city and county. She stated, “we are still seeing removals that are unnecessary, and the city is not sure who is responsible.”
Local groups are making efforts to save the remaining trees by supplying watering trucks, conducting property tree surveys, and planning a long-term planting program, ensuring that the trees which are vital to cooling California’s communities are protected.
