Background

On Friday, May 15, 2026, an aircraft flying over Santa Rosa Island in Channel Islands National Park reported a wildfire. National Park Service (NPS) staff already on the island confirmed it later that morning. The Santa Rosa Island Fire is located on the southeastern end of the island in remote and rugged terrain. This is a full-suppression human-caused wildfire and is under investigation. A team of Burned Area Emergency Response (BAER) specialists will be on the island through approximately June 10 evaluating post-fire conditions and identifying immediate risks. The team includes engineers, ecologists, hydrologists, archaeologists, and wildland fire specialists who will assess soil stability, watershed conditions, infrastructure damage, threats to natural and cultural resources, and other post-fire impacts. Their findings will help guide emergency stabilization efforts and inform decisions about public access.

• Emergency response overview:

"Current Conditions:A team of Burned Area Emergency Response (BAER) specialists will spend approximately one week on the island evaluating post-fire conditions and identifying immediate risks to public safety, infrastructure, and natural and cultural resources. Hazardous conditions can persist for weeks or months after a wildfire and may exist both inside and outside the burned area. Potential hazards include unstable soils, weakened trees, damaged infrastructure, falling rocks, erosion, and altered trail conditions. Closures:Santa Rosa Island is closed to all day and overnight use through at least June 30, 2026, due to the wildfire. All Water Canyon Campground reservations have been cancelled through this date and visitors have been notified by email. Campground reservation holders with bookings through August 14, 2026, have also been informed that the wildfire may affect their stay. If additional cancellations are needed, they will receive follow-up emails. Overnight and backcountry camping within the southeastern quadrant of Santa Rosa Island will remain closed for the remainder of the 2026 recreation season."

• Significant events:

"On 6/5, the Burned Area Emergency Response (BAER) team arrived on the island. The team received an inbriefing from National Park Service (NPS) staff and the departing wildland fire crew and toured the island and fire area. They were informed of fire history, post-fire concerns, and priorities. The crew will spend the next several days collecting data in the field."

The Forest Service's Burned Area Emergency Response (BAER) program aims to protect visitors, employees and resources by addressing post-fire dangers. Wildfires can lead to severe land damage, posing risks like erosion, flooding and infrastructure harm. BAER teams collect data to aid federal, state and local emergency agencies in assisting affected communities and landowners.

Fire containment

What does 100% containment mean?

Note that full containment doesn't mean the fire is completely out. In this case, it means that firefighters have managed to get a line completely around the emergency response's perimeter and it is now stopped from spreading. A fully contained wildfire may continue to burn within the containment perimeter but is not likely to spread.

However, there's a significant difference between containing and controlling a wildfire. After the fire is fully contained, the next step is to control it. Controlling a fire means ensuring that the fire can't spread or cross the containment line.

Containment is part of a larger plan for managing a wildfire. It is normally expressed as a percentage and it refers to how much of the fire perimeter has been surrounded/enclosed by a control line that firefighters create. The containment percentage indicates a certain level of control, but it doesn't always correlate to safety level. Also, it's important to note that containment doesn't mean a fire is out.

How is containment measured?

The incident's central command constantly receives progress reports from firefighters on the ground. As the fireline is constructed, inspected or reinforced, mappers record those details to adjust the containment percentage. The percentage tells the public how much of the fire perimeter is believed to not go beyond the control lines.
