The article examines new wildfire protection regulations in California that could ban nearly all plants in an 'ember-resistant zone' near homes. Researchers argue that healthy green vegetation can actually help slow fire spread and shield houses from embers, contradicting the proposed regulations. The mention of past urban fire patterns in areas like Los Angeles underscores how vegetation can influence fire behavior. If these regulations remain unchanged, they may face significant public backlash, reflecting wider implications for fire safety beyond California.
Research into how vegetation can reduce fire risk is a relatively new area of study. However, the findings from plant flammability studies and examination of patterns of where vegetation and homes survive large urban fires highlight its importance.
Wildfire safety guidelines have long encouraged homeowners to avoid having flammable materials next to their homes. But the state's plan for an 'ember-resistant zone' goes further by also prohibiting grass, shrubs, and many trees in that area.
