fire on Santa Rosa Island within Channel Islands scorched tens of thousands of acres, the state’s largest fire of the year so far. Containment efforts are advancing as of late May, with crews working to control the fire, while structures including two historic buildings were destroyed. Access to the island was restricted to protect rare ecosystems. The fire originated when a mariner’s distress flare was fired, according to Coast Guard and National Park Service reports. Containment has improved with multi-agency coordination. No civilian or firefighter fatalities or injuries have been reported so far. Environmental impacts on the island's plant and animal life continue to be a focus of suppression-repair efforts.
