Fire‑Risk Plants and Smoke Hazards
Entities: France · World Health Organization · eucalyptus · Syndicat des Sapeurs‑Pompiers Volontaires de France · Office National des Forêts (ONF)
Overview
An initial advisory in July identified specific garden plants that increase fire danger, issuing a brief notice for outdoor safety.
A later, detailed WHO briefing expanded the scope, warning that smoke from wildfires, vegetation fires and building fires carries fine particles (PM2.5), carbon monoxide and other irritants that can aggravate respiratory and cardiovascular conditions. The health agency recommended limiting outdoor activity, keeping windows closed and following local air‑quality guidance. It also identified resinous conifers such as cedars, pines and thujas, dense‑rooted heather, eucalyptus, and certain palms as especially combustible, urging homeowners to replace them with less flammable species like oak or ash and to maintain clear vegetation buffers around structures.
During the 2026 European heatwave, France saw extensive wildfires that burned over 500 ha in the Écrins, with PM2.5 concentrations reaching 70 µg/m³. Health experts reiterated WHO advice to limit outdoor activity, keep windows and doors shut, and use indoor air filtration—especially for children who inhale more pollutants per body weight. French authorities launched a volunteer‑registration platform, increased forest‑service patrols, and issued regional advisories urging removal of highly flammable garden hedges such as thuya and cypress, alongside the previously cited species.
