Santa Rosa Island Wildfire Burns Over 16,000 Acres, Threatens Rare Ecosystems
California's largest wildfire of 2026 has scorched over 16,600 acres on Santa Rosa Island, part of Channel Islands National Park. The fire, which started after a flare gun was used by a stranded sailor, remains 0% contained. Dry winds, low humidity, and warm temperatures are fueling the blaze, which has already destroyed two historic structures and threatens rare plant species, including the iconic Torrey pines. Fire crews are working in rugged terrain to protect key areas, such as the Vail and Vickers Ranch historic district. Additional firefighting resources, including a Hotshot crew, are being deployed. The fire has consumed over 30% of the island's 53,000 acres, and its impact on the island's unique ecosystem is still being assessed.
