What Happened
A wildfire on Santa Rosa Island, the second-largest island in Channel Islands National Park, was first spotted from aircraft and confirmed by the National Park Service on the morning of May 15, 2026.

Why this Matters to You
Santa Rosa Island was closed to the public for part of May 2026. The fire's impact on a rare stand of Torrey pines could affect the long-term ecological health of this unique national park. The scale of the fire may also indicate challenges for fire management in sensitive island ecosystems.
What's Next
Firefighters will continue working to contain the perimeter of the fire. The National Park Service may need to assess the damage to the island's habitats, including the rare Torrey pine stand, to determine recovery plans. Public access to Santa Rosa Island is likely to remain restricted until the fire is contained and safety is assured.
